RESUMEN

The evolving landscape of personalized medicine necessitates a shift from traditional therapeutic interventions towards precision-driven approaches. Embracing this paradigm, our research probes the therapeutic efficacy of the aqueous crude extract (ACE) of Calocybe indica in cervical cancer treatment, merging botanical insights with advanced molecular research. We observed that ACE exerts significant influences on nuclear morphology and cell cycle modulation, further inducing early apoptosis and showcasing prebiotic attributes. Characterization of ACE have identified several phytochemicals including significant presence of octadeconoic acid. Simultaneously, utilizing advanced Molecular Dynamics (MD) simulations, we deciphered the intricate molecular interactions between Vascular Endothelial Growth Factor (VEGF) and Octadecanoic acid to establish C.indica's role as an anticancer agent. Our study delineates Octadecanoic acid's potential as a robust binding partner for VEGF, with comprehensive analyses from RMSD and RMSF profiles highlighting the stability and adaptability of the protein-ligand interactions. Further in-depth thermodynamic explorations via MM-GBSA calculations reveal the binding landscape of the VEGF-Octadecanoic acid complex. Emerging therapeutic innovations, encompassing proteolysis-targeting chimeras (PROTACs) and avant-garde nanocarriers, are discussed in the context of their synergy with compounds like Calocybe indica P&C. This convergence underscores the profound therapeutic potential awaiting clinical exploration. This study offers a holistic perspective on the promising therapeutic avenues facilitated by C. indica against cervical cancer, intricately woven with advanced molecular interactions and the prospective integration of precision therapeutics in modern oncology.

RESUMEN

The fourth most frequent type of cancer in women and the leading cause of mortality for females worldwide is cervical cancer. Traditionally, medicinal plants have been utilized to treat various illnesses and ailments. The molecular docking method is used in the current study to look into the phytoconstituents of Juglans regia's possible anticancer effects on cervical cancer target proteins. This work uses the microarray dataset analysis of GSE63678 from the NCBI Gene Expression Omnibus database to find differentially expressed genes. Furthermore, protein-protein interactions of differentially expressed genes were constructed using network biology techniques. The top five hub genes (IGF1, FGF2, ESR1, MYL9, and MYH11) are then determined by computing topological parameters with Cytohubba. In addition, molecular docking research was performed on Juglans regia phytocompounds that were extracted from the IMPPAT database versus hub genes that had been identified. Utilizing molecular dynamics, simulation confirmed that prioritized docked complexes with low binding energies were stable.

RESUMEN

BACKGROUND: The intriguing connection between selenium and cancer resembles a captivating puzzle that keeps researchers engaged and curious. While selenium has shown promise in reducing cancer risks through supplementation, its interaction with epigenetics in cervical cancer remains a fascinating yet largely unexplored realm. Unraveling the intricacies of selenium's role and its interaction with epigenetic factors could unlock valuable insights in the battle against this complex disease. RESULT: Selenium has shown remarkable inhibitory effects on cervical cancer cells in various ways. In in vitro studies, it effectively inhibits the proliferation, migration, and invasion of cervical cancer cells, while promoting apoptosis. Selenium also demonstrates significant inhibitory effects on human cervical cancer-derived organoids. Furthermore, in an in vivo study, the administration of selenium dioxide solution effectively suppresses the growth of cervical cancer tumors in mice. One of the mechanisms behind selenium's inhibitory effects is its ability to inhibit histone demethylases, specifically JMJD3 and UTX. This inhibition is observed both in vitro and in vivo. Notably, when JMJD3 and UTX are inhibited with GSK-J4, similar biological effects are observed in both in vitro and in vivo models, effectively inhibiting organoid models derived from cervical cancer patients. Inhibiting JMJD3 and UTX also induces G2/M phase arrest, promotes cellular apoptosis, and reverses epithelial-mesenchymal transition (EMT). ChIP-qPCR analysis confirms that JMJD3 and UTX inhibition increases the recruitment of a specific histone modification, H3K27me3, to the transcription start sites (TSS) of target genes in cervical cancer cells (HeLa and SiHa cells). Furthermore, the expressions of JMJD3 and UTX are found to be significantly higher in cervical cancer tissues compared to adjacent normal cervical tissues, suggesting their potential as therapeutic targets. CONCLUSIONS: Our study highlights the significant inhibitory effects of selenium on the growth, migration, and invasion of cervical cancer cells, promoting apoptosis and displaying promising potential as a therapeutic agent. We identified the histone demethylases JMJD3 and UTX as specific targets of selenium, and their inhibition replicates the observed effects on cancer cell behavior. These findings suggest that JMJD3 and UTX could be valuable targets for selenium-based treatments of cervical cancer.

RESUMEN

BACKGROUND: Cervical cancer is a prevalent and deadly malignancy in females, with chemotherapy often proving ineffective due to significant side effects and the development of chemo-resistance. This study investigates the medicinal potential of Clerodendrum infortunatum linn. , a genus with approximately 500 species in the Lamiaceae family. Limited research exists on the species of Clerodendrum infortunatum and its various solvent extracts. OBJECTIVE: The study aims to assess the anti-cancer properties of different solvent extracts from this plant on human cervical cancer cells. METHODS: The study examines the plant's phytochemical components and their potential to inhibit cancer growth. Aerial parts of the plant were extracted using the Soxhlet method, and the presence of Rutin, Quercetin, and Gallic Acid in specific solvent extracts was validated through High-Performance Thin Layer Chromatography (HPTLC). In vitro assays, including MTT, Apoptosis, Cell Cycle analysis, Intracellular Reactive Oxygen Species assessment, and Gene expression PCR, were conducted to investigate the plant's anti-cancer properties further. RESULTS: The outcomes of the phytochemical assessment indicated that Rutin was predominantly present in the water extract, with quercetin being more concentrated in the decoction, and the hydro-alcoholic extract showing elevated levels of gallic acid. Notably, the decoction extract demonstrated the highest cytotoxic activity, primarily through early apoptosis and arrests in the S-phase and G2M phases. Clerodendrum infortunatum exhibited a reduction in Intracellular Reactive Oxygen Species. The gene expression analysis disclosed an impact on the BCL-2 gene. CONCLUSION: Notably, Clerodendrum infortunatum exhibited the ability to initiate early apoptosis, halt the cell cycle at the S and G2M phases, and diminish levels of reactive oxygen species significantly. The gene expression analysis revealed an influence on the BCL-2 gene. To sum up, this research underscores the encouraging cytotoxic and antioxidant attributes of Clerodendrum infortunatum, implying its potential for cervical cancer treatment.

RESUMEN

BACKGROUND: Pinellia pedatisecta Schott extract (PE) is extracted from Pinellia pedatisecta Schott (PPS), a traditional Chinese medicinal plant with the potential for direct anticancer effects or eliciting an anti-tumor response by activating the immune system. PURPOSE: To explore PE's ability and mechanism to reconstruct cisplatin's immunogenicity. METHODS: Cervical cancer cells were treated with cisplatin (CDDP) and/or PE. The exposure of calreticulin (CRT) on cell membrane was investigated by flow cytometry. The extracellular of ATP and HMGB1 was investigated by Western blot analysis, immunofluorescence and ELISA assay. Changes in immune profiles were using flow cytometry in vaccination and anti-tumor assays in vivo. Lastly, the mechanism of PE influenced the ROS/ERS pathway was examined by ROS assay kit, flow cytometry and Western blotting. RESULTS: PE treatment induced translocation of CRT from the endoplasmic reticulum to the cell membrane of tumor cells, concomitantly triggering immunogenic cell death (ICD). In terms of mechanisms, endoplasmic reticulum (ER) stress relievers could impede the ability of PE to induce immunogenicity. This indicates that PE is activated by ER stress, leading to subsequent induction of ICD. Upon analyzing RNA-seq data, it was observed that PE primarily induces programmed cell death in tumors by impeding upstream antioxidant mechanisms. Additionally, it transforms dying tumor cells into vaccines, activating a series of immune responses. CONCLUSIONS: This study observed for the first time that PE-induced CRT exposure on the membrane of cervical cancer cells compensates for the defect of nonimmunogenic cell death inducer CDDP thereby stimulating potent ICD. This ability restores the immunogenicity of CDDP through ER stress induced by the ROS signal. ROS played a role in PE's ability to induce ICD, leading to increased expression of ER stress-related proteins, including ATF3 and IRE-1α. PE exerted anti-cancer effects by increasing the ROS levels, and ROS/ERS signaling may be a potential avenue for cervical cancer treatment. Hence, the synergistic use of PE and CDDP holds potential for enhancing immunochemotherapy in cancer treatment.

RESUMEN

BACKGROUND: Phytochemicals have become a growing source of alternative medicine in developing countries due to the poor prognosis, high cost of conventional pharmaceuticals, and undesirable effects associated with mainstream cancer treatment. OBJECTIVE: This study was aimed at investigating the anticancer effect of some selected Nigerian medicinal plants used in cancer treatment. These include ethanol extracts of Dialium guineense root (DGR), Dialium guineense leaves (DGL), Jateorhiza macrantha leaves (JML), Musanga cecropioides leaves (MCL), Musanga cecropioides stembark (MCSB), Piptadeniastrum africanum stembark (PASB), Piptadeniastrum africanum root (PAR), Pupalia lappacea flower tops (PLF), Raphiostylis beninensis root (RBR), Raphiostylis beninensis leaves (RBL), Ritchiea capparoides leaves (RCL), Ritchiea capparoides stembark (RCSB), and Triplochiton scleroxylon stembark (TSB). METHODS: The cytotoxic activity of the extracts was examined using a brine shrimp lethality assay and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay against three cancer cell lines, including MCF-7, HUH-7, and HeLa. The selectivity of all extracts towards cancer cells was investigated using normal lung fibroblasts (MRC-5). Cell migration and colony-forming assays of active extracts against MCF-7 cells were also performed. Additionally, the total polyphenolic contents of the active extracts were estimated using standard methods. RESULTS: The extract of PASB had the highest cytotoxicity (LC50 = 1.58 µg/mL) on the brine shrimps compared to vincristine sulphate (LC50 = 2.24 µg/mL). In the cell viability assay, all the extracts produced significant (p < 0.05) growth inhibitory effects against all cell lines tested in a dose-dependent manner. All extracts were selective to cancer cells at varying degrees. Worth mentioning are the extracts of MCL, DGR, RBR, and PASB, which exhibited 14-, 7-, 6- and 2-fold selectivity toward MCF-7 cancer cells relative to normal lung fibroblast (MRC-5), respectively. These four extracts also significantly inhibited cell migration and colony formation in MCF-7-treated cells in dose-dependent manners. Considerable amounts of phenolics, flavonoids, and proanthocyanidins were detected in all extracts evaluated. CONCLUSION: These findings advocate the continued development of MCL, DGR, RBR, and PASB as potential chemotherapeutic agents.

RESUMEN

OBJECTIVE: Investigate the anti-cancerous potential of garlic-derived nanovesicles (GDNVs), exploring their cytotoxic effects on HeLa and PC-3 cell lines, and elucidate the underlying mechanisms, including apoptosis induction and inhibition of epithelial-mesenchymal transition (EMT). METHODS: GDNVs were isolated using differential centrifugation and ultracentrifugation. Characterization was performed through dynamic light scattering (DLS), field-emission scanning electron microscopy (FESEM), and Fourier-transform infrared spectroscopy (FTIR). Cytotoxicity assessments on HeLa and PC-3 cell lines using MTT assay. Apoptosis induction was evaluated through nuclear morphology changes and quantification of apoptotic cells using DAPI and PI/annexin V analysis. Western blot of apoptosis-related proteins (bcl-2, bax, caspase-3) was analysed. Anti-metastatic potential was assessed using wound healing assay and EMT transition inhibition. RESULTS: Garlic-derived nanovesicles (GDNVs), characterized by a size of 134.2 nm, demonstrated a substantial and dose- as well as time-dependent anti-proliferative impact on HeLa and PC-3 cell lines. The induction of apoptosis was unequivocally established through discernible modifications in nuclear morphology. The apoptotic cell count in HeLa and PC-3 cells increased by 42.4 ± 4.2% and 38.2 ± 3.2%, respectively. Comprehensive Western blot demonstrated alterations in the expression of key apoptotic regulators, namely bcl-2, bax, and caspase-3, providing robust evidence for the initiation of apoptosis. Furthermore, GDNVs exerted a significant inhibitory effect (p < 0.001) on the migratory potential of both HeLa and PC-3 cells. Moreover, there was a discernible association between GDNVs and the suppression of Epithelial-Mesenchymal Transition (EMT), emphasizing their role in impeding the metastatic potential of these cancer cell lines. CONCLUSION: This study establishes, for the first time, the anti-cancerous potential of GDNVs. The observed dose- and time-dependent anti-proliferative effects, selective cytotoxicity, apoptosis induction, and anti-migratory potential highlight GDNVs as a promising candidate for cancer treatment.

RESUMEN

As a global malignancy with high mortality rate, targeted drug development for Uterine Cervical Neoplasms is an important direction. The traditional formula Guizhi Fuling Wan (GFW) is widely used in gynecological diseases. However, its potential mechanism of action remains to be discovered. We retrieved GFW and cervical squamous cell carcinoma (CSCC) targets from public databases. The protein-protein interaction network was obtained by string computational analysis and imported Cytoscape_v3.9.0 to obtain the core network and the top 10 Hub genes. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes were used for enrichment analysis of the core network, and then molecular docking to verify whether the selected signaling pathway binds well to the core node. Finally, clinical prognostic analysis and expression differences of Hub genes were validated using the Cancer Genome Atlas database and R language. Our search yielded 152 common targets for GFW and CSCC. The interleukin-17 signaling pathway, tumor necrosis factor signaling pathway, and Toll-like signaling pathway were then selected for further molecular docking from the hub genes enrichment analysis results, which showed good binding. Among the Hub genes, JUN, VEGFA, IL1B, and EGF had a poor prognosis for CSCC. In conclusion, this study illustrates that GFW can have adjuvant therapeutic effects on CSCC through multiple targets and multiple pathways, providing a basis for further research.

RESUMEN

CONTEXT: Chinese medicine injections (CMIs) are widely used as adjuvant therapy for cervical cancer in China. However, the effectiveness of different types of CMIs remains uncertain. OBJECTIVE: To assess the effectiveness and safety of CMIs when used in conjunction with radiotherapy (RT) or concurrent chemoradiotherapy (CCRT), particularly in combination with cisplatin (DDP), docetaxel plus cisplatin (DP), and paclitaxel plus cisplatin (TP). MATERIALS AND METHODS: Randomized controlled trials (RCTs) were searched in databases including CNKI, WanFang, VIP, SinoMed, PubMed, Cochrane Library, Embase, and Web of Science from inception to September 2023. We calculated the risk ratio with a 95% confidence interval and the surface under the cumulative ranking area curve (SUCRA) for the clinical efficacy rate (CER), the efficacy rate by Karnofsky Performance Status (KPS), and the rates of leukopenia reduction (LRR) and gastrointestinal reactions (GRR). RESULTS: Forty-seven RCTs were included, including nine CMI types: Aidi, Fufangkushen, Huangqi, Kangai (KA), Kanglaite (KLT), Renshenduotang, Shenqifuzheng (SQFZ), Shenmai (SM), and Yadanzi. KLT and KA were likely optimal choices with radiotherapy for CER and KPS, respectively. KA and KLT were optimal choices with RT + DDP for CER and GRR, respectively. KLT was the likely optimal choice with RT + DP for CER and KA for both KPS and GRR. SM and SQFZ were the likely optimal choices with RT + TP for CER and LRR, respectively. CONCLUSIONS: The optimal recommendation depends on whether CMIs are used with radiotherapy or concurrent chemoradiotherapy. More high-quality RCTs are needed to confirm further and update the existing evidence.

RESUMEN

OBJECTIVE: To investigate the effects of asperuloside on cervical cancer based on endoplasmic reticulum (ER) stress and mitochondrial pathway. METHODS: Different doses (12.5-800 µg/mL) of asperuloside were used to treat cervical cancer cell lines Hela and CaSki to calculate the half maximal inhibitory concentration (IC50) of asperuloside. The cell proliferation was analyzed by clone formation assay. Cell apoptosis, intracellular reactive oxygen species (ROS) and mitochondrial membrane potential were determined by flow cytometry. The protein expressions of cleaved-caspase-3, Bcl-2, Bax, Cyt-c, cleaved-caspase-4 and glucose-regulated protein 78 (GRP78) were analyzed by Western blot. And the inhibitor of ER stress, 4-phenyl butyric acid (4-PBA) was used to treat cervical cancer cells to further verify the role of ER stress in the apoptosis of cervical cancer cells induced by asperuloside. RESULTS: Asperuloside of 325, 650, and 1300 µg/mL significantly inhibited the proliferation and promoted apoptosis of Hela and CaSki cells (P<0.01). All doses of asperuloside significantly increased intracellular ROS levels, reduced mitochondrial membrane potential, significantly reduced Bcl-2 protein expression level, and increased Bax, Cyt-c, GRP78 and cleaved-caspase-4 expressions (P<0.01). In addition, 10 mmol/L 4-PBA treatment significantly promoted cell proliferation and reduced apoptosis (P<0.05), and 650 µg/mL asperuloside could reverse 4-PBA-induced increased cell proliferation, decreased apoptosis and cleaved-caspase-3, -4 and GRP78 protein expressions (P<0.05). CONCLUSION: Our study revealed the role of asperuloside in cervical cancer, suggesting that asperuloside promotes apoptosis of cervical cancer cells through ER stress-mitochondrial pathway.

RESUMEN

BACKGROUND: The interaction of microRNA with Chinese herbal medicines is a promising therapeutic approach for prevention of cervical cancer. METHODS: Western blotting or qRT-PCR were carried out to identify the expression of NCAPG2 and miR-638. A tetrandrine (TET) cell model was used to explore the effects of miR-638 and its target gene NCAPG2 using CCK-8, transwell, wound healing, and western blot assays. Furthermore, luciferase activity assay was conducted to measure the interaction among TET, NCAPG2 and miR-638. RESULTS: Under TET treatment, Hela and SiHa cells exhibited repressed cell viability, migration, invasion, and epithelial-mesenchymal transition (EMT), and these effects were further enhanced by high expression of miR-638. In contrast, NCAPG2 expression was low in TET-treated cells and had an opposite effect to that of miR-638. CONCLUSION: We highlighted that miR-638 suppresses cervical cancer progression by inhibiting NCAPG2 under tetrandrine treatment.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Cervical cancer is one of the most common malignancies in women that continues to be a public health problem worldwide. Human papillomavirus (HPV) infection is closely related as the causative agent of almost all cases of cervical cancer. Currently, there is no effective treatment for the persistence of HPV. Although vaccines have shown promising results in recent years, they are still a costly strategy for developing countries and have no therapeutic effect on existing infections, which is why the need arises to search for new strategies that can be used in treatment, suppressing oncogenic HPV and disease progression. Extracts of Schisandra Chinensis and Pueraria lobata have been used in traditional medicine, and it has been shown in recent years that some of their bioactive compounds have pharmacological, antioxidant, antitumor, apoptotic, and proliferation effects in HPV-positive cells. However, its mechanism of action has yet to be fully explored. AIM OF THE STUDY: The following study aimed to determine the chemical composition, antioxidant activity, and potential antiproliferative and viral oncogene effects of natural extracts of S. chinensis and P. lobata on HPV-18 positive cervical cancer cells. MATERIALS AND METHODS: The HPV-18-positive HeLa cells were treated for 24 and 48 h with the ethanolic extracts of S chinensis and P. lobata. Subsequently, cell viability was evaluated using the resazurin method, the effect on the cell cycle of the extracts (1.0, 10, and 100 µg/mL) was measured by flow cytometry, the gene of expression of the E6/E7, P53, BCL-2, and E2F-1 were determined by RT-PCR and the protein expression of p53, Ki-67, x|and Bcl-2 by immunohistochemistry. Additionally, the chemical characterization of the two extracts was carried out using LC-MS, and the total phenolics content (TPC), Total flavonoid content (TFC), and DPPH radical scavenging capacity were determined. Data were analyzed using the Mann-Whitney and Kruskal Wallis U test with GraphPad Prism 6 software. RESULTS: The natural extracts of Schisandra chinensis and Pueraria lobata induced down-regulation of E6 HPV oncogene (p<0.05) and a strong up-regulation of P53 (p<0.05), E2F-1 (p<0.05), and Bcl-2 (p<0.05) gene expression. Simultaneously, the natural extracts tend to increase the p53 protein levels and arrest the cell cycle of HeLa in the G1/S phase (p<0.05). Investigated extracts were characterized by the occurrence of bioactive lignans and isoflavones in S. chinensis and P. lobata, respectively. CONCLUSION: The extracts of S. chinensis and P. lobata within their chemical characterization mainly present lignan and isoflavone-type compounds, which are probably responsible for inhibiting the expression of the HPV E6 oncogene and inducing an increase in the expression of p53, Bcl -2 and E2F-1 producing cell cycle detection in S phase in HeLa cells. Therefore, these extracts are good candidates to continue studying their antiviral and antiproliferative potential in cells transformed by HPV.

RESUMEN

Radiotherapy is still the recommended treatment for cervical cancer. However, radioresistance and radiation-induced side effects remain one of the biggest clinical problems. Selenium (Se) has been confirmed to exhibit radiation-enhancing effects for cancer treatment. However, Se species dominate the biological activities and which form of Se possesses better radiosensitizing properties and radiation safety remains elusive. Here, different Se species (the valence state of Se ranged from - 2, 0, +4 to + 6) synergy screen was carried out to identify the potential radiosensitizing effects and radiation safety of Se against cervical cancer. We found that the therapeutic effects varied with the changes in the Se valence state. Sodium selenite (+4) displayed strong cancer-killing effects but also possessed severe cytotoxicity. Sodium selenate (+6) neither enhanced the killing effects of X-ray nor possessed anticancer activity by its alone treatment. Although nano-selenium (0), especially Let-SeNPs, has better radiosensitizing activity, the - 2 organic Se, such as selenadiazole derivative SeD (-2) exhibited more potent anticancer effects and possessed a higher safe index. Overall, the selected Se drugs were able to synergize with X-ray to inhibit cell growth, clone formation, and cell migration by triggering G2/M phase arrest and apoptosis, and SeD (-2) was found to exhibit more potent enhancing capacity. Further mechanism studies showed that SeD mediated p53 pathway activation by inducing DNA damage through promoting ROS production. Additionally, SeD combined with X-ray therapy can induce an anti-tumor immune response in vivo. More importantly, SeD combined with X-ray significantly inhibited the liver metastasis of tumor cells and alleviated the side effects caused by radiation therapy in tumor-bearing mice. Taken together, this study demonstrates the radiosensitization and radiation safety effects of different Se species, which may shed light on the application of such Se-containing drugs serving as side effects-reducing agents for cervical cancer radiation treatment.

RESUMEN

BACKGROUND: Cervical cancer is a prevalent malignancy among women globally. OBJECTIVE: We aimed to uncover the mechanism of action of kaempferol in the treatment of cervical cancer using an integrated approach that combines metabolomics with network pharmacology. METHODS: Initially, we investigated the specific metabolites and potential pathways influenced by kaempferol in the pathological progression of cervical cancer, employing UHPLC-Q-Orbitrap MS metabolomics. In addition, network pharmacology analysis was performed to ascertain the pivotal targets of kaempferol in the context of CC therapy. RESULTS: Metabolomics analysis indicated that the therapeutic effect of kaempferol on cervical cancer is primarily associated with 11 differential metabolites and 7 metabolite pathways. These pathways include arginine and proline metabolism, the tricarboxylic acid cycle, phenylalanine, tyrosine, and tryptophan biosynthesis, fatty acid biosynthesis, glycerophospholipid metabolism, pantothenate and CoA biosynthesis, and tyrosine metabolism. Additionally, kaempferol was found to regulate 3 differential metabolites, namely palmitic acid, citric acid, and L-tyrosine, by directly targeting 7 specific proteins, including AKR1B1, CS, EGFR, PLA2G1B, PPARG, SLCO2B1, and SRC. Furthermore, molecular docking demonstrated strong binding affinities between kaempferol and 7 crucial targets. CONCLUSION: This study elucidates the intricate mechanisms by which kaempferol acts against cervical cancer. Furthermore, this research offers a novel approach to investigating the potential pharmacological mechanisms of action exhibited by natural compounds.

RESUMEN

Cervical cancer is one of the most prevalent malignancies among females and is correlated with a significant fatality rate. Chemotherapy is the most common treatment for cervical cancer; however, it has a low success rate due to significant side effects and the incidence of chemo-resistance. Curcumin, a polyphenolic natural compound derived from turmeric, acts as an antioxidant by diffusing across cell membranes into the endoplasmic reticulum, mitochondria, and nucleus, where it performs its effects. As a result, it's been promoted as a chemo-preventive, anti-metastatic, and anti-angiogenic agent. As a consequence, the main goal of the present review was to gather research information that looked at the link between curcumin and its derivatives against cervical cancer.

RESUMEN

BACKGROUND: Xihuang Pills/Capsules have a longstanding history of utilization in traditional Chinese medicine (TCM) for treating cancer. Nevertheless, a comprehensive investigation is required regarding the specific impacts and safety of Xihuang Pills/Capsules in individuals with uterine cervical neoplasms. Thus, conducting a meta-analysis is essential to evaluate the clinical effectiveness of combining Xihuang Pills/Capsules with Western medicine in patients with cervical neoplasms. METHODS: The research involved searching 5 English and 4 Chinese databases for randomized controlled trials (RCTs) investigating the use of Xihuang Pills/Capsules in conjunction with Western medicine for treating uterine cervical neoplasms. Subsequently, statistical analysis was carried out using Review Manager software (version 5.3). RESULTS: This research encompassed 10 RCTs involving 937 patients. The findings revealed that the combination of Xihuang Pills/Capsules with Western medicine treatment led to improvements in various aspects of the patients' condition. Specifically, there was an enhancement in the short-term efficacy rate (risk ratio [RR] = 1.14, 95% confidence interval [CI]: 1.06-1.22, P = .0003), Karnofsky performance score (KPS) (mean difference [MD] = 5.90, 95% CI: 0.54-11.26, P = .03), survival rates, CD3+, CD3 + CD4+, CD3 + CD8+, CD3-CD56 + cells, and immunoglobulin M in patients with uterine cervical neoplasms. Moreover, the combination treatment resulted in a reduction of adverse reactions, including gastrointestinal reactions (RR = 0.52, 95% CI: 0.42-0.64, P < .00001), radiation proctitis (RR = 0.47, 95% CI: 0.33-0.68, P < .0001), myelosuppression (RR = 0.41, 95% CI: 0.26-0.64, P < .0001), as well as carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCC-Ag) levels. Additionally, the treatment exhibited an inhibitory effect on white blood cells (WBCs) and platelets (PLTs). CONCLUSION: The amalgamation of Xihuang Pills/Capsules with conventional anti-tumor therapy proves to be both effective and safe in the treatment of cervical neoplasms. However, further validation through high-quality RCTs is necessary to substantiate these findings.

RESUMEN

Cu4 O3 is the least explored copper oxide, and its nanoformulation is anticipated to have important therapeutic potential especially against cancer. The current study aimed to biosynthesize Cu4 O3 nanoparticles (NPs) using an aqueous extract of pumpkin seeds and evaluate its antiproliferative efficacy against cervical cells after screening on different cancer cell lines. The obtained NPs were characterized by different spectroscopic analyses, such as UV-vis, thermogravimetric, energy dispersive X-ray, and Fourier-transform infrared spectroscopy (FTIR). In addition, high-resolution transmission electron microscopes (HR-TEM) were used to observe the morphology of the biosynthesized NPs. The UV-vis spectra showed a peak at around 332 nm, confirming the formation of Cu4 O3 NPs. Moreover, FTIR and TAG analyses identified the presence of various bioactive phytoconstituents that might have worked as capping and stabilization agents and comparative stable NPs at very high temperatures, respectively. The HR-TEM data showed the spherical shape of Cu4 O3 NPs in the range of 100 nm. The Cu4 O3 NPs was screened on three different cancer cell lines viz., Hela, MDA-MB-231, and HCT-116 using cytotoxicity (MTT) reduction assay. In addition, Vero was taken as a normal epithelial (control) cell. The high responsive cell line in terms of least IC50 was further assessed for its anticancer potential using a battery of biological tests, including morphological alterations, induction of apoptosis/ROS generation, regulation of mitochondrial membrane potential (MMP), and suppression of cell adhesion/migration. Vero cells (control) showed a slight decline in % cell viability even at the highest tested Cu4 O3 NPs concentration. However, all the studied cancer cells viz., MDA-MB-231, HCT 116, and HeLa cells showed a dose-dependent decline in cell viability after the treatment with Cu4 O3 NPs with a calculated IC50 value of 10, 11, and 7.2 µg/mL, respectively. Based on the above data, Hela cells were chosen for further studies, that showed induction of apoptosis from 3.5 to 9-folds by three different staining techniques acridine orange/ethidium bromide (AO/EB), 4',6-diamidino-2-phenylindole (DAPI), and propidium iodide (PI). The enhanced production of reactive oxygen species (>3.5-fold), modulation in MMP, and suppression of cell adhesion/migration were observed in the cells treated with Cu4 O3 NPs. The current study obtained the significant antiproliferative potential of Cu4 O3 NPs against the cervical cancer cell line, which needs to be confirmed further in a suitable in vivo model. Based on our results, we also recommend the green-based, eco-friendly, and cost-effective alternative method for synthesizing novel nanoformulation.

RESUMEN

Carlina acaulis is highly valued in the traditional medicine of many European countries for its diuretic, cholagogue, anthelmintic, laxative, and emetic properties. Moreover, practitioners of natural medicine indicate that it has anti-cancer potential. However, its phytochemistry is still little known. In the present study, the polyphenolic composition of the plant was investigated using ultra-high-performance liquid chromatography coupled with a high-resolution/quadrupole time-of-flight mass spectrometer (UHPLC-HR/QTOF/MS-PDA). The fractionation of the extract was carried out using liquid-liquid extraction and preparative chromatography techniques. Cytotoxicity was assessed based on neutral red and MTT assays. The obtained data showed that the species is rich in chlorogenic acids and C-glycosides of luteolin and apigenin. The total amount of chlorogenic acids was 12.6 mg/g. Among flavonoids, kaempferol dihexosidipentose and schaftoside were the most abundant, reaching approximately 3 mg/g, followed by isoorientin, vitexin-2-O-rhamnoside, and vicenin II, each with a content of approximately 2 mg/g. Furthermore, the cytotoxic potential of the plant against human colorectal adenocarcinoma (HT29) and human cervical cancer (HeLa) cells was investigated using the normal epithelial colon cell line (CCD 841CoTr) as a reference. It has been demonstrated that the ethyl acetate fraction was the most abundant in polyphenolic compounds and had the most promising anticancer activity. Further fractionation allowed for the obtaining of some subfractions that differed in phytochemical composition. The subfractions containing polyphenolic acids and flavonoids were characterized by low cytotoxicity against cancer and normal cell lines. Meanwhile, the subfraction with fatty acids was active and decreased the viability of HeLa and HT29 with minimal negative effects on CCD 841CoTr. The effect was probably linked to traumatic acid, which was present in the fraction at a concentration of 147 mg/g of dried weight. The research demonstrated the significant potential of C. acaulis as a plant with promising attributes, thus justifying further exploration of its biological activity.

RESUMEN

Our previous laboratory findings suggested the beneficial effects of epigallocatechin gallate (EGCG) against cervical cancer (CC) cells survival. The present study is aimed at identifying the effects of EGCG in preventing the actions of epidermal growth factor (EGF) in human papilloma virus (HPV) 68 positive ME180 and HPV negative C33A CC cells. An elevated level of EGF in tumor micro-environment (TME) is linked to the metastasis of several cancers including CC. We hypothesized that EGCG has the ability to block the actions of EGF. To test this, survival assay was performed in cells treated with or without EGF and EGCG. The mitochondrial activity of cells was ascertained using MTT assay and mitored staining. Protein and non-protein components in the extracellular matrix such as collagen and sulphated glycosaminoglycans (GAGs) were evaluated using sirius red and alcian blue staining, respectively. Matrix metalloproteinase-2 (MMP-2) gene expression and enzymatic activity were assessed using real time-reverse transcriptase-polymerase chain reaction (RT-PCR) and gelatin zymography. Wound healing assay was performed to assess the EGF induced migratory ability and its inhibition by EGCG pre-treatment. Clonogenic assay showed that EGCG pre-treatment blocked the EGF driven colony formation. In silico analysis performed identified the efficacy of EGCG in binding with different domains of EGF receptor (EGFR). EGCG pre-treatment prevented the epithelial-mesenchymal transition (EMT) and metabolic activity induced by EGF, this is associated with concomitant reduction in the gene expression and enzyme activity of MMP-2. Further, reduced migration and ability to form colonies were observed in EGCG pre-treated cells when stimulated with EGF. HPV positive ME180 cells showed increased migratory and clonogenic ability upon EGF stimulation, whose effects were not much significant in HPV negative C33A cells. EGCG effectively blocked the actions of EGF in both HPV positive and HPV negative conditions and can be advocated as supplementary therapy for the management of EGF driven CC. However, further studies using cell line-derived xenograft (CDX)/patient-derived xenograft (PDX) model system is warranted to validate the therapeutic utility of EGCG.

RESUMEN

Piper longum L. is widely cultivated for food, medicine, and other purposes in tropical and subtropical regions. Sixteen compounds including nine new amide alkaloids were isolated from the roots of P. longum. The structures of these compounds were determined by spectroscopic data. All compounds showed better anti-inflammatory activities (IC50 = 1.90 ± 0.68-40.22 ± 0.45 µM) compared to indomethacin (IC50 = 52.88 ± 3.56 µM). Among the isolated compounds, five dimeric amide alkaloids exhibited synergistic effects with three chemotherapeutic drugs (paclitaxel, adriamycin, or vincristine) against cervical cancer cells. Moreover, these dimeric amide alkaloids also enhanced the efficacy of paclitaxel in paclitaxel-resistant cervical cancer cells. The combination treatment of one of these dimeric amide alkaloids and paclitaxel promoted cancer cell apoptosis, which is related to the Src/ERK/STAT3 signaling pathway.
