RESUMEN

Fritillaria cirrhosa, an endangered plant endemic to plateau regions, faces escalating cadmium (Cd) stress due to pollution in the Qinghai-Tibet Plateau. This study employed physiological, cytological, and multi-omics techniques to investigate the toxic effects of Cd stress and detoxification mechanisms of F. cirrhosa. The results demonstrated that Cd caused severe damage to cell membranes and organelles, leading to significant oxidative damage and reducing photosynthesis, alkaloid and nucleoside contents, and biomass. Cd application increased cell wall thickness by 167.89% in leaves and 445.78% in bulbs, leading to weight percentage of Cd increases of 76.00% and 257.14%, respectively. PER, CESA, PME, and SUS, genes responsible for cell wall thickening, were significantly upregulated. Additionally, the levels of metabolites participating in the scavenging of reactive oxygen species, including oxidized glutathione, D-proline, L-citrulline, and putrescine, were significantly increased under Cd stress. Combined multi-omics analyses revealed that glutathione metabolism and cell wall biosynthesis pathways jointly constituted the detoxification mechanism of F. cirrhosa in response to Cd stress. This study provides a theoretical basis for further screening of new cultivars for Cd tolerance and developing appropriate cultivation strategies to alleviate Cd toxicity.

RESUMEN

Advancements in genomics have dramatically accelerated the research on medicinal plants, and the development of herbgenomics has promoted the "Project of 1K Medicinal Plant Genome" to decipher their genetic code. However, it is difficult to obtain their high-quality whole genomes because of the prevalence of polyploidy and/or high genomic heterozygosity. Whole genomes of 123 medicinal plants were published until September 2022. These published genome sequences were investigated in this review, covering their classification, research teams, ploidy, medicinal functions, and sequencing strategies. More than 1,000 institutes or universities around the world and 50 countries are conducting research on medicinal plant genomes. Diploid species account for a majority of sequenced medicinal plants. The whole genomes of plants in the Poaceae family are the most studied. Almost 40% of the published papers studied species with tonifying, replenishing, and heat-cleaning medicinal effects. Medicinal plants are still in the process of domestication as compared with crops, thereby resulting in unclear genetic backgrounds and the lack of pure lines, thus making their genomes more difficult to complete. In addition, there is still no clear routine framework for a medicinal plant to obtain a high-quality whole genome. Herein, a clear and complete strategy has been originally proposed for creating a high-quality whole genome of medicinal plants. Moreover, whole genome-based biological studies of medicinal plants, including breeding and biosynthesis, were reviewed. We also advocate that a research platform of model medicinal plants should be established to promote the genomics research of medicinal plants.

RESUMEN

Lung cancer is a chronic wasting disease with insidious onset and long treatment cycle. Exosomes are specialized extracellular vesicles, at first exosomes were considered as a transporter of cellular metabolic wastes, but recently many studies have identified exosomes which contain a variety of biologically active substances that play a role in the regulation of cellular communication and physiological functions. Exosomes play an important role in the development of lung cancer and can promote metastasis through a variety of mechanisms. However, at the same time, researchers have also discovered that immune cells can also inhibit lung cancer through exosomes. In addition, researchers have discovered that some specific miRNAs in exosomes can be used as markers for early diagnosis of lung cancer. Engineering exosomes may be one of the strategies to enhance the clinical translational application of exosomes in the future, for example, strategies such as modifying exosomes to enhance targeting or utilizing exosomes as carriers for drug delivery have been explored. but more studies are needed to verify the safety and efficacy. This article reviews the latest research on exosomes in the field of lung cancer, from the mechanism of lung cancer development, the functions of immune cell-derived exosomes and tumor-derived exosomes, to the early diagnosis of lung cancer.

RESUMEN

Phospholipase C (PLC) has important biological functions in specific cancer types, immune disorders and neurodegeneration. Here, an ultrasensitive electrochemical sensor for PLC was developed via signal amplification based on breathing atom transfer radical polymerization (ATRP). First, phosphatidylethanolamine (PE) was immobilized on the surface of a gold electrode by L-cysteine and cross-linker. Then, PE was specially hydrolyzed by PLC to obtain the phosphate groups and tethered with the ATRP initiator α-bromophenacetic acid (BPAA) by the coordination action of Zr4+. After the breathing ATRP, a large number of electroactive monomers (ferrocenylmethyl methacrylate, FcMMA) were successfully grafted from BPAA. The experimental results indicated that the detection signal of the obtained electrode (sensor) was proportional to the concentration of PLC. The sensor showed a low detection limit of 0.270 U L-1 and a wide linear range of 1-40 U L-1 (R2 = 0.997). Most importantly, the sensor was successfully applied to detect PLC in breast cancer cells (MCF-7, MDA-MB-231) and nontumor cells (MCF-10A). The value obtained by our electrochemical sensor had no obvious difference from that determined by the commercial ELISA kit. These results showed that the fabricated PLC sensor had acceptable potential in clinical applications.

RESUMEN

Purpose: Quality control circle (QCC) has acquired success in many fields in healthcare industry as a process management tool, whereas its efficacy in surgical antimicrobial prophylaxis (SAP) remains unknown. This study aimed to implement QCC interventions to improve the appropriateness of SAP. Methods: A QCC activity team was established to grasp the current situation of SAP in clean surgery procedure, set target, formulate corresponding countermeasures and implement and review them in stages. The plan-do-check-act (PDCA) method was cyclically applied. Results: The appropriateness of antibiotic prophylaxis before (January to December 2020) and after (January to December 2021) the implementation of QCC activities were evaluated based on relevant international and Chinese SAP guidelines. The overall SAP appropriateness was significantly improved from 68.72% before QCC to 93.7% post QCC implementation (P<0.01). A significant improvement (P<0.05) was also determined for each category: selection (from 78.82% to 96.06%), duration (from 90.15% to 96.46%), indication (from 94.09% to 97.64%), timing of first dose (from 96.55% to 99.21%), antimicrobial usage (from 96.8% to 99.41%), re-dosing of antimicrobial (from 96.55% to 99.21%). Conclusion: Implementation of a QCC program can optimize the use of antibiotics and improve the appropriateness of SAP and is of practical importance to their standardization.

RESUMEN

The evaluation of germplasm resources is the prerequisite for the development, utilization, and conservation of Chinese medicinal resources. The selection of excellent germplasm is the key to the breeding and orderly production of Pinellia ternata. In this study, 21 germplasm materials of P. ternata from major production areas in China were collected and analyzed for population diversity after phenotypic preliminary screening. The results have revealed that the P. ternata population has abundant phenotypic variation, and the phenotypic changes could be divided into five phenotypes in terms of organ trait variation. Further analysis of variation in 20 quantitative traits of the population revealed that the coefficient of variation for adenosine content(339.05%) was the largest, while the coefficient of variation for the underground plant height(16.35%) was the smallest. Correlation analysis showed that there was a strong correlation among various traits, with 52 pairs of traits showing highly significant correlation(P<0.01) and 19 pairs of traits showing a significant correlation(P<0.05). The 21 germplasms in the test could be classified into three major clusters by cluster analysis, with Cluster Ⅱ having the highest number and content of nucleosides, making it suitable for the selection and breeding of P. ternata varieties with high content of nucleosides. The yield in Cluster Ⅲ was higher than that in other groups, making it suitable for the selection and breeding of P. ternata varieties with a high yield. All trait indicators could be simplified into five principal component factors through principal component analysis, and the cumulative contribution rate was up to 86.04%. Further, comprehensive analysis using membership function and stepwise regression analysis identified nine traits, such as plant height, main leaf length, and underground plant height as characteristic indicators for the comprehensive evaluation of germplasm resources of P. ternata. BX007, BX008, and BX005 were identified as germplasms with both high yield and high uridine content, with BX007 having the highest uridine content of 479.51 µg·g~(-1). It belonged to the germplasm of P. ternata with double bulbils and could be cultivated as a potential good variety. Based on the phenotypic classification of P. ternata, systematic resource evaluation was carried out in this study, which could lay a foundation for the excavation of genetic resources and the breeding of new varieties of P. ternata.

RESUMEN

BACKGROUND: Intradural lumbar disc herniation (ILDH) is special type of lumbar disc herniation in which the lumbar nucleus pulposus prolapses and enters the dura mater. ILDHs comprise 0.04-0.33% of all herniated discs. In most cases, the diagnosis could not be confirmed preoperatively by identifying the typical features of ILDH in radiological evaluation. In the current report, we present a case of ILDH at lumbar 2/3 level and discuss the clinical presentations, typical imaging features, treatments, and outcomes. CASE DESCRIPTION: We describe a rare case of ILDH. The patient was a 65-year-old man with pain in waist and back, and with bilateral radiating pain of lower extremities and fatigue for more than 2 weeks. Magnetic resonance imaging (MRI) revealed a large round, low-density mass at lumbar 2/3, which was easily mimicked as an intradural spinal tumor lesion. While enhanced MRI showed the typical rim enhancement sign and "Hawk beak" sign. Due to progressive decrease in muscle strength in both lower limbs, posterior microscopically assisted laminectomy, dural incision of the lumbar 2/3 was performed. Pathological examination revealed degenerated fibrous connective tissue and cartilage tissue. The patient's lower back pain and radiating pain and numbness of both legs improved remarkably postoperatively, and he became asymptomatic at 3 months and 1-year postoperatively. CONCLUSIONS: ILDH is a rare intervertebral disc herniation in clinical practice. The pathogenesis of ILDH may be related to aseptic inflammatory edema, closely fixing of ventral dura and the posterior longitudinal ligament, repeated mechanical action and chemical corrosion. Typical rim enhancement sign, "Hawk beak" sign and "Y" sign are important features of MRI in diagnosing ILDH, and intraspinal gas is also helpful in computed tomography (CT) diagnosis of ILDH. Prompt microscopically assisted laminectomy, dura mater incision to remove the intradural disc, pedicle screw fixation regardless of fusion, surgical results are usually favorable. We also reviewed the literature and discussed the epidemiology, potential pathogenesis, diagnosis, treatment and poor prognostic factors of ILDH.

RESUMEN

Asparagi Radix (AR), a traditional Chinese medicine, is the dried roots of Asparagus cochinchinensis (Lour.) Merr. Modern pharmacological studies have shown that AR has various excellent bioactivities, such as antioxidative, antitumor, antibacterial, anti-inflammatory, and hypoglycemic effects. However, the quality control method of AR is incomplete and there are various AR adulterants in markets due to their similar morphological characters. Here, holistic and practical quality evaluation methods were developed to chemically distinguish three common Asparagus species in markets, including Asparagus cochinchinensis (Lour.) Merr., Asparagus officinalis L., and Asparagus lycopodineus (Baker) F.T.Wang & Tang. The chemical constituents of three species were rapidly tentatively annotated using a combination of ultra-high pressure liquid chromatography-linear ion trap-orbitrap high resolution mass spectrometry (UHPLC-LTQ-Orbitrap-MS) and molecular networking (MN). Fifty-six steroidal saponins were annotated, including common and characteristic chemical constituents of the three Asparagus species. Besides, to establish holistic and practical methods to differentiate three Asparagus species, an HPLC-ELSD (evaporative light scattering detector) was applied for fingerprint analysis and content determination of the sum of protoneodioscin and protodioscin of twenty samples. Each Asparagus species showed characteristic chemical profile and AR showed much higher level of the sum of protoneodioscin and protodioscin than that in the others. The above analyses showed that the three Asparagus species mainly contain steroidal saponins and the developed HPLC-ELSD profile of saponin can be used to differentiate them. In conclusion, this study reveals the different chemical constituents of three Asparagus species and provides relatively feasible quality evaluation methods for them which are essential for the rational utilization of these Asparagus species.

RESUMEN

RNA-binding proteins (RBPs) are significantly dysregulated in glioma. In this study, we demonstrated the upregulation of Nuclear cap-binding subunit 3 (NCBP3) in glioma tissues and cells. Further, knockdown of NCBP3 inhibited the malignant progression of glioma. NCBP3 directly bound to small nucleolar RNA host gene 6 (SNHG6) and stabilized SNHG6 expression. In contrast, the gastrulation brain homeobox 2 (GBX2) transcription factor was downregulated in glioma tissues and cells. SNHG6 inhibited GBX2 transcription by mediating the H3K27me3 modification induced by polycomb repressive complex 2 (PRC2). Moreover, GBX2 decreased the promoter activities and downregulated the expression of the flotillin protein family 1 (FLOT1) oncogene. In conclusion, NCBP3/SNHG6 inhibits GBX2 transcription in a PRC2-dependent manner to facilitate the malignant progression of gliomas.

RESUMEN

Physalis angulata L. is a medicinal plant of the Solanaceae family, which is used to produce a variety of steroids. The present study reports on the cytotoxic withanolides of this plant. The species of Physalis angulata L. was identified by DNA barcoding techniques. Two new withanolides (1-2), together with six known analogues (3-8), were isolated from the whole plant of Physalis angulata L. The structures of these new compounds were determined on the basis of extensive spectroscopic data analyses and electronic circular dichroism (ECD) calculations. The withanolides exhibited strong cytotoxic activities against A549, Hela and p388 cell lines. Furthermore, compounds 1 and 2 induced typical apoptotic cell death in A549 cell line according to the evaluation of the apoptosis-inducing activity by flow cytometric analysis.

RESUMEN

Mounting evidence has illustrated the vital roles of long non-coding RNAs (lncRNAs in gastric cancer (GC). Nevertheless, the majority of their roles and mechanisms in GC are still largely unknown. In this study, we investigate the roles of lncRNA SLC25A5-AS1 on tumourigenesis and explore its potential mechanisms in GC. The results showed that the expressions of SLC25A5-AS1 in GC were significantly lower than that of adjacent normal tissues, which were significantly associated with tumour size, TNM stage and lymph node metastasis. Moreover, SLC25A5-AS1 could inhibit GC cell proliferation, induce G1/G1 cell cycle arrest and cell apoptosis in vitro, as well as GC growth in vivo. Dual-luciferase reporter assay confirmed the direct interaction between SLC25A5-AS1 and miR-19a-3p, rescue experiment showed that co-transfection miR-19a-3p mimics and pcDNA-SLC25A5-AS1 could partially restore the ability of GC cell proliferation and the inhibition of cell apoptosis. The mechanism analyses further found that SLC25A5-AS1 might act as a competing endogenous RNAs (ceRNA), which was involved in the derepression of PTEN expression, a target gene of miR-19a-3p, and regulate malignant phenotype via PI3K/AKT signalling pathway in GC. Taken together, this study indicated that SLC25A5-AS1 was down-regulated in GC and functioned as a suppressor in the progression of GC. Moreover, it could act as a ceRNA to regulate cellular behaviours via miR-19a-3p/PTEN/PI3K/AKT signalling pathway. Thus, SLC25A5-AS1 might be served as a potential target for cancer therapeutics in GC.

RESUMEN

Early evidence indicates that the long non-coding RNA CCAL plays a critical role in cancer progression and metastasis. However, the overall biological role and clinical significance of CCAL in gastric tumourigenesis and progression remain largely unknown. We observed that CCAL was upregulated in gastric cancer tissues and was associated with the tumour-node-metastasis stage. Functional experiments showed that CCAL promoted gastric cancer cell proliferation and metastasis in vitro and in vivo. Luciferase reporter assay indicated that CCAL directly bind to miR-149. Moreover, knockdown of CCAL significantly reduced the expression of FOXM1, a direct target of miR-149. We also showed that FOXM1 suppression by miR-149 could be partially rescued by CCAL overexpression. In addition, we identified a negative correlation between the mRNA expression of CCAL and miR-149 in gastric cancer tissues. Furthermore, we observed a negative correlation between the expression of miR-149 and FOXM1 and a positive correlation between CCAL and FOXM1 levels. These results demonstrated that the CCAL/miR-149/FOXM1 axis functions as a key regulator in gastric cancer metastasis and CCAL potentially represents a biomarker for diagnosis and potential target for therapy in the future.

RESUMEN

BACKGROUND: Rhizoma Paridis (Chonglou) is a commonly used and precious traditional Chinese medicine. Paris polyphylla Smith var. yunnanensis (Franch.) Hand. -Mazz. and Paris polyphylla Smith var. chinensis (Franch.) Hara are the two main sources of Chonglou under the monograph of Rhizoma Paridis in Chinese Pharmacopoeia. In the local marketplace, however, this medicine is prone to be accidentally contaminated, deliberately substituted or admixed with other species that are similar to Rhizoma Paridis in shape and color. Consequently, these adulterations might compromise quality control and result in considerable health concerns for consumers. This study aims to develop a rapid and sensitive method for accurate identification of Rhizoma Paridis and its common adulterants. METHODS: DNA barcoding coupled with high resolution melting analysis was applied in this research to distinguish Rhizoma Paridis from its adulteration. The internal transcribed spacer 2 (ITS2) barcode was selected for HRM analysis to produce standard melting profile of the selected species. DNA of the tested herbal medicines was isolated and their melting profiles were generated and compared with the standard melting profile of P. polyphylla var. chinensis. RESULTS: The results indicate that the ITS2 molecular regions coupled with HRM analysis can effectively differentiate nine herbal species, including two authentic origins of Chonglou and their seven common adulterants. Ten herbal medicines labeled "Chonglou" obtained from a local market were collected and identified with our methods, and their sequence information was analyzed to validate the accuracy of HRM analysis. CONCLUSIONS: DNA barcoding coupled with HRM analysis is a accurate, reliable, rapid, cost-effective and robust tool, which could contribute to the quality control of Rhizoma Paridis in the supply chain of the natural health product industry (NHP).

RESUMEN

The proliferation and apoptosis of tumor cells are regulated by a variety of microRNAs (miRs). miR­21 can inhibit the apoptosis of cancer cells in vitro. Tumor necrosis factor α (TNF­α) serves an important role in the induction of proliferation of cervical cancer cells. Previous studies have demonstrated that the expression level of miR­21 is associated with TNF­α expression in alveolar macrophages. However, to the best of our knowledge, whether miR­21 regulates TNF­α in cervical cells has not been reported. The present study was designed to investigate whether miR­21 regulates TNF­α expression, proliferation and apoptosis of cervical cancer cells. miR­21, miR­21 inhibitor and control miRNA were synthesized and transfected into HeLa cervical cancer cells. Reverse transcription­quantitative polymerase chain reaction was used to measure the expression levels of miR­21 and TNF­α at the mRNA level. Western blotting was used to measure the expression levels of TNF­α at the protein level. MTT assay and Hoechest­33342 staining were used to measure the proliferation and apoptosis of HeLa cells. miR­21 was identified to upregulate the mRNA and protein expression levels of TNF­α. Furthermore, upregulation of TNF­α enhanced the proliferation capability of HeLa cells. Changes in the expression levels of miR­21 and TNF­α did not significantly affect the apoptosis of Hela cells. In conclusion, the present study demonstrated that miR­21 regulates the expression of TNF­α in HeLa cells. Additionally, the expression level of TNF­α was positively associated with the proliferation capability of Hela cells, but not apoptosis. Therefore, miR­21 regulates the proliferation of HeLa cells through regulation of TNF­α. These results provide novel potential therapeutic targets for the treatment of cervical cancer.

RESUMEN

BACKGROUND: This meta-analysis aimed to demonstrate the efficacy and safety of intravenous glucocorticoids for reducing pain intensity and postoperative nausea and vomiting (PONV) in patients undergoing total joint arthroplasty (TJA). METHODS: PubMed, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and Google databases were searched for randomized controlled trials (RCTs) comparing intravenous glucocorticoids versus no intravenous glucocorticoids or sham for patients undergoing TJA. Outcomes included visual analogue scale (VAS) pain at 12, 24, and 48 hours; the occurrence of PONV; length of hospital stay; the occurrence of infection; and blood glucose levels after surgery. We calculated risk ratios (RR) with a 95% confidence interval (CI) for dichotomous outcomes and the weighted mean difference (WMD) with a 95% CI for continuous outcomes. Trial sequential analysis was also used to verify the pooled results. RESULTS: Thirteen clinical trials involving 821 patients were ultimately included in this meta-analysis. The pooled results indicated that intravenous steroids can decrease VAS at 12 hours (WMD = -8.54, 95% CI -11.55 to -5.53, P = 0.000; I = 35.1%), 24 hours (WMD = -7.48, 95% CI -13.38 to -1.59, P = 0.013; I = 91.8%), and 48 hours (WMD = -1.90, 95% CI -3.75 to -0.05, P = 0.044; I = 84.5%). Intravenous steroids can decrease the occurrence of PONV (RR = 0.56, 95% CI 0.44-0.73, P = 0.000; I = 33.1%). There was no significant difference in the length of hospital stay, occurrence of infection, and blood glucose levels after surgery. CONCLUSION: Intravenous glucocorticoids not only alleviate early pain intensity but also decrease PONV after TJA. More high-quality RCTs are required to determine the safety of glucocorticoids before making final recommendations.

RESUMEN

UNLABELLED: The synthesizing evidence on the effectiveness of using oil massage to promote the growth of infants is still lacking. This paper aims to determine whether oil massage can promote the physical and neurobehavioral growth of infants according to variables and to evaluate whether oil massage is safe for infant skin. ELIGIBILITY CRITERIA: The randomized controlled trials, clinical controlled trials and quasi-experimentally designed trials published prior to or in 2014 were searched according to predetermined inclusion criteria and exclusion criteria in Medline, PubMed, Ovid, the Cochran Library, and Chinese databases, including the China National Knowledge Infrastructure, Wan Fang database and VIP journal integration platform. Besides, the grey lectures were searched as well through Open Grey, GrayLIT Network and Clinical Trials.gov. SAMPLE: Eight studies out of 625 retrieved articles were eligible for inclusion. RESULTS: Oil massage increased the infant weights, lengths and head circumferences. However, it did not promote a significant advantage in neurobehavioral scores or cause a significant risk of adverse skin reactions. IMPLICATIONS: The core mechanisms and standard procedures of oil massage as well as the preferred oil type should be the focus of future nursing practice and research. CONCLUSIONS: Oil massage may effectively improve the physical growth of infants, and it presents a limited risk of adverse skin reactions. However, the relationship between neurodevelopment and oil massage requires further study.

RESUMEN

The issues including excessive pesticide residues and heavy metal contamination have become the bottle-neck in the development of Chinese herbal medicines. Compared with traditional chemical pesticides, biological pesticides, especially botanical pesticides, are more safe and environment-friendly, which were beneficial to the quality improvement Chinese medicinal materials. Though there exists a weak basic research and it is hard for promotion and regulation, the policy of good and the desire for botanical pesticides will accelerate its development, and replace traditional chemical pesticides gradually. This paper reviews the current situation of botanical pesticides, and gives some pertinence suggestions according to the existing problems and challenges. Research on botanical pesticides will become the key point to solve the problem of excessive pesticides residues and heavy metal contamination, and promote the healthy development of Chinese materia medica.

RESUMEN

Objective: To establish a novel approach based on DNA barcode sequence, so as to guarantee the quality stability of Chinese medicinal materials. Methods: Eight species of Paris plants were collected, and a standard DNA barcode library was developed by ITS loci. Furthermore, the barcodes also used to identify the seed and seedling products that purchased from the markets. Results: ITS loci can stably and accurately distinguish Paris polyphylla var. yunnanensis and its adulterants. Conclusion: The seeds and seedlings of Chinese medicinal materials need to be properly authenticated before planting,and DNA barcoding has been found to be effective for this purpose.

RESUMEN

Epimedii Folium (Yinyanghuo in Chinese) is one of the most commonly used traditional Chinese medicines. Its main active components are flavonoids, which exhibit multiple biological activities, such as promotion of bone formation and sexual function, protection of the nervous system, and prevention of cardiovascular diseases. Flavonoids also show anti-inflammatory and anticancer effects. Various effective methods, including genetic and chemical approaches, have been developed for the quality control of Yinyanghuo. In this review, the studies conducted in the last decade about the chemical constituents, quality control, and bioactivity of Yinyanghuo are summarized and discussed.

RESUMEN

INTRODUCTION: Triterpenoids isolated from Ganoderma lucidum are a class of naturally occurring compounds and structurally highly oxidized lanostanes. Accumulated data show that triterpenoids exhibit a broad spectrum of anti-cancer properties, including anti-proliferative, anti-metastatic and anti-angiogenic activities. A systematic summary and knowledge of future prospects are necessary to facilitate further studies on this species. AREAS COVERED: This review aims to summarize and analyze the current knowledge on the anti-cancer properties and mechanisms of G. lucidum triterpenoids (GLTs) and discuss the future prospects of the application of GLTs in cancer treatment. EXPERT OPINION: Extensive research over the last 10 years has provided evidence of the anti-cancer activities of GLTs in different stages of carcinogenesis. These activities include cell cycle arrest, induction of apoptosis and autophagy, and suppression of metastasis and angiogenesis. However, the exact molecular mechanisms involved in these processes remain unclear. Androgen receptor, nuclear factor-kappa B, activator protein-1, p53 and 14-3-3 are reportedly involved in the anti-cancer properties of GLTs. Animal models further shed light on the development of GLTs as anti-cancer agents. However, more research and clinical trials are necessary to exploit these compounds.
