Anticancer activities of natural abietic acid.

Cancer is the main cause of death in the world. There are several therapies that are in practice for cancer cure including radiotherapy, chemotherapy, and surgery. Among the chemotherapies, natural products are considered comparable safe, easily available and cost effective. Approximately 60% of cancer approved FDA drugs are natural products including vinblastine, doxorubicin, and paclitaxel. These natural products have complex structures due to which they work against cancer through different molecular pathways, STAT3, NF-kB, PI3K/AKT/mTOR, cell cycle arrest, mitochondrial dependent pathway, extrinsic apoptosis pathway, autophagy, mitophagy and ferroptosis. AA is a natural abietane diterpenoid compound from Pinus palustris and Pimenta racemose var. grissea with different pharmacological activities including anti-inflammatory, anti-convulsant, anti-obesity and anti-allergic. Recently it has been reported with its anticancer activities through different molecular mechanisms including NF-kB, PI3K/AKT, call cycle arrest at G0/G1 phase, mitochondrial dependent pathway, extrinsic apoptosis pathway, AMPK pathway and ferroptosis pathways. The literature survey reveals that there is no review on AA anticancer molecular mechanisms, therefore in current review, we summarize the anticancer molecular mechanisms of AA.

NMDA receptor modulation by Esculetin: Investigating behavioral, biochemical and neurochemical effects in schizophrenic mice model.

Schizophrenia, a global mental health disorder affecting approximately 1 % of the population, is characterized by neurotransmitter dysregulation, particularly dopamine, serotonin, and glutamate. Current antipsychotic therapies, despite their efficacy, are accompanied by adverse effects, which has motivated researchers to investigate more secure substitutes. This study examines the potential antipsychotic effects of esculetin, a natural coumarin derivative recognized for its wide-ranging pharmacological activities (anti-inflammatory, antioxidant, anti-pathogenic, anticancer, and neuroprotective), in animal model of schizophrenia induced by ketamine. In order to induce disease, acute and chronic ketamine administration was performed on Swiss albino mice, supplemented with esculetin (as the test substance) and clozapine (as the reference standard). Behavioral studies and biochemical assays were performed to evaluate positive, negative, and cognitive symptoms of schizophrenia, as well as antioxidant and oxidant levels in various brain regions. Esculetin demonstrated significant improvements in behavioral symptoms, attenuated oxidative stress and neuroinflammation, and modulated neurotransmitter levels. Afterwards, ELISA was performed to evaluate levels of schizophrenia biomarkers AChE, BDNF. Moreover, proinflammatory cytokines (IL-6 and TNF-α) and NF-κB were also determined. Histopathological parameters of under study brain parts i.e., hippocampus, cortex and striata were also assessed. Esculetin and clozapine significantly (***p < 0.0001) altered ketamine induced behavioral symptoms and attenuated ketamine induced oxidative stress and neuroinflammation. Additionally, esculetin significantly (***p < 0.0001) altered neurotransmitter (dopamine, serotonin, glutamate) levels. ELISA analysis depicts ketamine reduced BDNF levels in hippocampus, cortex and striata while esculetin significantly (***p < 0.0001) increased BDNF levels in under study three parts of brain. Histopathological changes were seen in test groups. The findings of this study indicate that esculetin may have therapeutic potential in the treatment of schizophrenia induced by ketamine. As a result, esculetin may have the potential to be utilized as a treatment for schizophrenia.

Synthesis of ZnO and PEG-ZnO nanoparticles (NPs) with controlled size for biological evaluation.

The objective of this research was to produce the smallest possible ZnO nanoparticles through an adapted wet chemical process and subsequently, to fabricate a core-shell structure utilizing polyethylene glycol (PEG) as the shell component. The synthesis, size, and shape of the NPs were confirmed using advanced techniques. The resulting clustered NPs were round and had a size of 9.8 nm. Both plain and core-shell NPs were tested for their antibacterial properties against multi-drug resistant bacteria strains (E. cloacae, E. amnigenus, S. flexneri, S. odorifacae, Citrobacter, and E. coli), with concentrations of 500, 1000, and 1500 µg ml-1 used for testing. Both types of NPs demonstrated antibacterial activity against the tested pathogens, with the core-shell NPs being more effective. The synthesized NPs were biocompatible with human red blood cells, with a low level of hemolysis observed. The biocompatibility of the core-shell NPs was significantly enhanced by the presence of the PEG added as the shell. In addition, their effectiveness as photosensitizers for cancer treatment via photodynamic therapy (PDT) was evaluated. MTT assay was used to evaluate the cytotoxicity of ZnO and PEG-ZnO, and the results showed that these NPs were able to generate ROS inside tumor cells upon irradiation, leading to apoptosis and cell death, making them a promising candidate for PDT.

Synthesis of new class of non-sulfonamide bis-benzimidazoles as antitumor agents by inhibiting carbonic anhydrase-IX enzyme.

In several types of cancers, the expression of carbonic anhydrase-IX (CA-IX) enzyme is elevated than its normal level which ultimately plays a key role in the tumor growth of epithelial cells in breast and lung cancer by acidifying tumor microenvironment, therefore, inhibition of this target is important in antitumor therapy. We have synthesized bis-benzimidazole derivatives (1-25) by using 3,3'-diaminobenzidine and various aromatic aldehydes and characterized by various spectroscopic methods (UV/Visible, 1HNMR, 13CNMR, and mass spectrometry). Their inhibitory potential for human CA-IX (hCA-IX) was evaluated in-vitro, where several synthesized derivatives showed potent inhibition of hCA-IX (IC50 values in range of 5.23 ± 1.05 to 40.10 ± 1.78 µM) and compounds 3-5, 7-8, 13-16, 21 and 23 showed superior activity than the standard drug "acetazolamide" (IC50 = 18.24 ± 1.43 µM). Furthermore, all these compounds showed no toxicity on human fibroblast cell lines (BJ cell lines). Moreover, molecular docking was carried out to predict their binding modes in the active site of CA-IX and revealed a significant role of imidazole ring of synthesized entities in their effective binding with the specific residues of CA-IX. The obtained results paved the way for further in vivo and other pharmacological studies for the optimization of these molecules as possible anti-cancer agents.

Cytotoxic Activity of Phytoconstituents Isolated from Monotheca buxifolia against Hepatocellular Carcinoma Cell Line HepG2: In Vitro and Molecular Docking Studies.

Natural products and conventional chemotherapeutic drugs are believed to enhance anticancer treatment efficacy while lowering toxicity. The current study investigates the cytotoxic and apoptogenic effects of Monotheca buxifolia bioactive compounds on HepG2 cell lines. MTT assay was used to assess the effect on the viability of HepG2 cells. Morphological changes were investigated. Annexin-V-FITC/PI was used to demonstrate apoptotic activity. A molecular dynamics simulation study was carried out to investigate the compound binding pattern in the active site of the PPRAδ protein. MTT and annexin V-FITC/PI assays revealed that the isolated compounds lauric acid, oleanolic acid, and bis(2-ethylhexyl) phthalate inhibited the growth of hepatocellular cancer cells. The IC50 value for lauric acid was 56.46 ± 1.20 µg/mL, 31.94 ± 1.03 µg/mL for oleanolic acid, and 83.80 ± 2.18 µg/mL for bis(2-ethylhexyl) phthalate. Apoptosis was observed in 29.5, 52.1 and 22.4% of HepG2 cells treated with lauric acid, oleanolic acid, and bis(2-ethylhexyl) phthalate, respectively, after 24 h of treatment. Morphological assays and Hoechst staining microscopy revealed that the treatment caused morphological changes in the cell membrane and nuclear condensation. The high fluctuation indicates that various interactions were highly potent and widely adopted, and vice versa. Oleanolic acid displayed high residue fluctuation, remaining stable in the active site of the PPRAδ protein and involved in various interactions while remaining locally fluctuating in the binding sites of the other two compounds. These findings concluded that lauric acid, oleanolic acid, and bis(2-ethylhexyl) phthalate have a significant apoptogenic effect against HepG2 cells in inducing apoptosis. Our findings suggest that these bioactive compounds could be used as adjuvant therapies.

Sustained virological response to antiviral drugs in treatment of different genotypes of HCV cirrhotic patients.

Cirrhosis and liver cancer are both caused by hepatitis C virus (HCV) infection of the liver. Patients with HCV cirrhosis may be treated with one of many antiviral medications, depending on their specific genotype. Samples of cirrhotic HCV were obtained from 190 people at the Khyber Teaching Hospital and the Hayatabad Medical Complex in Peshawar, Pakistan. Multiplex and real-time PCR were used to assess the genotypes and viral loads of the samples, respectively. Sixty patients were given sofosbuvir plus daclatasvir with ribavirin, while the remaining 56 patients were given sofosbuvir with ribavirin for a period of 12-24 weeks. LFTs were also tracked both before and after therapy. Group I (sofosbuvir + daclatasvir) had a sustained virological response of 82.70 percent. Group II (sofosbuvir + daclatasvir with ribavirin) had an 86% sustained virological response, whereas group III (84% sustained virological response) received only ribavirin. When compared to other genotypes, genotype 3 showed the most impressive sustained virologic response (SVR) to the antiviral medicines. Based on the results of this trial, we propose sofosbuvir + daclatasvir ribavirin for the treatment of cirrhotic patients with various HCV genotypes since it produces the greatest sustained virological response.

Comparative study of microscale and macroscale technique for encapsulation of Calotropis gigantea extract in metal-conjugated nanomatrices for invasive ductal carcinoma.

The encapsulation of plant extract in nanomatrices has limitations due to its adhesion to walls, size control, high cost and long durations that results in low yield. Macroscale and microscale level techniques for development of micro/nanoparticles may impact the encapsulation of plant extract. This study aimed to evaluate the relative efficiency of microscale and macroscale techniques for encapsulation of plant extract, which is not compared yet. Keeping this in view, encapsulation of Calotropis gigantea leaves extract (CaG) was attained in silver-conjugated poliglusam nanomatrices (POL/Ag) to induce apoptosis in invasive ductal carcinoma (IDC) cells. The ethanolic CaG extract was prepared using percolation method and characterized by chemical tests for its active phytochemical compounds. The droplet-based microfluidic system was utilized as microscale encapsulation technique for CaG in nanomatrices at two different aqueous to oil flow rate ratios 1.0:1.5, and 1.0:3.0. Moreover, conventional batch system was utilized as macroscale encapsulation technique consisted of hot plate magnetic stirrer. The prepared nanomatrices were analysed for antioxidant activity using DPPH test and for cytotoxicity analysis using MCF-7 cells. The characteristic peaks of UV-Vis, FTIR and XRD spectrum confirmed the synthesis of CaG(POL/Ag) by both the encapsulation methods. However, microfluidic system was found to be more expedient because of attaining small and uniform sized silver nanoparticles (92 ± 19 nm) at high flow rate and achieving high encapsulation efficiency (80.25%) as compared to the conventional batch method (52.5%). CaG(POL/Ag) nanomatrices found to have significant antioxidant activity (p = 0.0014) against DPPH radical scavenging activity. The CaG(POL/Ag) of the smallest sized formulated by the microfluidic system has also shown the highest cytotoxicity (90%) as compared to batch method (70%) at 80 µg/mL. Our results indicate that the microscale technique using microfluidic system is a more efficient method to formulate size-controlled CaG(POL/Ag) nanomatrices and achieve high encapsulation of plant extract. Additionally, CaG(Pol/Ag) was found to be an efficient new combination for inducing potent (p < 0.0001) apoptosis in IDC cells. Therefore, CaG(Pol/Ag) can be further tested as an anti-cancer agent for in-vivo experiments.

Pharmacological screening of silibinin for antischizophrenic activity along with its acute toxicity evaluation in experimental animals.

Silibinin (SIL), a flavolignan extracted from the medicinal plant "silybum marianum (milk thistle)", has traditionally been used to treat liver disease. This phytochemical has displayed neuroprotective properties, its activity against schizophrenia is not elucidated. The present study was designed to evaluate the antipsychotic potential of silibinin and probe its toxic potential. The acute oral toxicity study was assessed as per OECD 425 guidelines. Animals were divided into two groups of female rats (n = 6): one group served as the normal control and the other group received a 2,000 mg/kg dose of SIL. We also evaluated the antipsychotic potential of SIL. To this end, animals were divided into six groups (n = 10) of mice for both the preventive and curative protocols. Group I (CMC 1 mL/kg) served as the normal control and received CMC 1 mL/kg; group II was the diseased group treated with ketamine (10 mg/kg) i.p; group III was the standard group treated with clozapine 1 mg/kg; groups IV, V, and VI served as the treatment groups, receiving SIL 50, 100, and 200 mg/kg, respectively, orally for both protocols. Improvement in positive symptoms of the disease was evaluated by stereotypy and hyperlocomotion, while negative symptoms (behavioral despair) were determined by a forced swim test and a tail suspension test in the mice models. The results suggested that the LD50 of SIL was greater than 2,000 mg/kg. Moreover, SIL prevented and reversed ketamine-induced increase in stereotypy (p < 0.001) and behavioral despair in the forced swim and tail suspension tests (p < 0.001). Taken together, the findings suggest that silibinin is a safe drug with low toxicity which demonstrates significant antipsychotic activity against the positive and negative symptoms of schizophrenia.

Anti-arthritic and toxicological evaluation of ethanolic extract of Alternanthera bettzickiana in rats.

In many developing countries, medicinal plants have long been used for therapeutic purposes due to their low cost and toxicity. This study evaluated the safety and anti-arthritic potential of Alternanthera bettzickiana ethanolic extract (ABEE). Acute oral toxicity (OECD 425) was tested in the safety evaluation. A limit test was used to identify the LD50 value. For an acute oral toxicity study a dose of 2000 mg/kg of ABEE was given orally to the treatment group, and the control group received distilled water at a rate of 10 ml/kg. Biochemical, hematological, and histopathological analyses were performed after 14 days. A formaldehyde 2% w/v solution was injected via i.p. to rats of all groups to prepare the arthritic model. Five groups were divided into control (D.H2O), standard (Diclofenac), and three groups receiving the plant extract at dose levels of 125 mg/kg, 250 mg/kg, and 500 mg/kg respectively. Treatment was continued for 10 days. Paw diameter and hematological and biochemical variables were quantified. ELISA was performed for the estimation of inflammatory cytokines. In the acute oral toxicity study, no mortality or morbidity were observed, so the LD50 of this plant was greater than 2000 mg/kg. ABEE decreased the paw diameter with the restoration of hematological and biochemical changes. SOD and CAT levels were increased while decreasing the MDA, NO, TNF-α, and IL-6 levels in arthritic rats. It is concluded that the use of A. bettzickiana has low toxicity, and it can be used for the treatment of arthritis.

Morchella esculenta mushroom polysaccharide attenuates diabetes and modulates intestinal permeability and gut microbiota in a type 2 diabetic mice model.

Type 2 diabetes mellitus (T2DM) is a health issue that causes serious worldwide economic problems. It has previously been reported that natural polysaccharides have been studied with regard to regulating the gut microbiota, which plays an important role in T2DM. Here, we investigate the effects of Morchella esculenta polysaccharide (MEP) on a high-fat diet (HFD) and streptozotocin (STZ)-induced T2DM in BALB/c mice. The administration of MEP effectively regulated hyperglycemia and hyperlipidemia and improved insulin sensitivity. We also determined an improvement in gut microbiota composition by 16sRNA pyrosequencing. Treatment with MEP showed an increase in beneficial bacteria, i.e., Lactobacillus and Firmicutes, while the proportion of the opportunistic bacteria Actinobacteria, Corynebacterium, and Facklamia decreased. Furthermore, the treatment of T2DM mice with MEP resulted in reduced endotoxemia and insulin resistance-related pro-inflammatory cytokines interleukin 1ß (IL-1ß), tumor necrosis factor-alpha (TNF-α), and interleukin 6 (IL-6). Moreover, MEP treatment improved intestinal permeability by modulating the expression of the colon tight-junction proteins zonula occludens-1 (ZO-1), occludin, claudin-1, and mucin-2 protein (MUC2). Additionally, MEP administration affects the metagenome of microbial communities in T2DM mice by altering the functional metabolic pathways. All these findings suggested that MEP is a beneficial prebiotic associated with ameliorating the gut microbiota and its metabolites in T2DM.

Sarcococca saligna Hydroalcoholic Extract Ameliorates Arthritis in Complete Freund's Adjuvant-Induced Arthritic Rats via Modulation of Inflammatory Biomarkers and Suppression of Oxidative Stress Markers.

Traditionally, Sarcococca saligna has been used for the treatment of arthritis and many other inflammatory disorders. The current study was planned to give scientific evidence to this traditional use of S. saligna. Phytochemical profiling of SSME was carried out by using electrospray ionization mass spectrometry (ESI-MS/MS). Complete Freund's adjuvant (CFA), 150 µL was injected in the subplantar region of the left hind paw to induce arthritis in rats. Aqueous methanolic extract of S. saligna (SSME) was administered orally at 250, 500, or 1000 mg/kg dose from the 7th day to the 28th day of the study to explore its anti-arthritic potential. Histopathological and radiographic assessment of joints and enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction (RT-PCR) analyses were performed. Determination of oxidative stress biomarkers in the serum was also carried out. ESI-MS/MS identified ten such phytoconstituents which have reported strong anti-inflammatory and anti-arthritic activity. The SSME extract considerably reduced paw inflammation and arthritic index, subdued cachexia, and significantly improved biochemical and hematological changes. Oxidative stress decreased in SSME administered rats dose-dependently. Histopathological and radiographic evaluations also showed the anti-arthritic activity of SSME, which was associated with the downregulation of tumor necrosis factor (TNF)-α, nuclear factor (NF)-kB, COX-2, interleukin (IL)-6, and IL-1ß and upregulation of I-kB, IL-4, and IL-10, in contrast to disease group rats. The outcomes of the study proposed that S. saligna have anti-arthritic potential, supporting its traditional use for rheumatoid arthritis treatment.

Preparation of mixed-mode stationary phase for separation of peptides and proteins in high performance liquid chromatography.

Porous silica particles were prepared by sol-gel method with some modification to get wide-pore particles. These particles were derivatized with N-phenylmaleimide-methylvinylisocyanate (PMI) and styrene by reversible addition fragmentation chain transfer (RAFT) polymerization to prepare N-phenylmaleimide embedded polystyrene (PMP) stationary phases. Narrow bore stainless steel column (100 × 1.8 mm i.d) was packed by slurry packing method. The chromatographic performance of PMP column was evaluated for the separation of synthetic peptides mixture composed of five peptides (Gly-Tyr, Gly-Leu-Tyr, Gly-Gly-Tyr-Arg, Tyr-Ile-Gly-Ser-Arg, Leucine enkephalin) and tryptic digest of human serum albumin (HAS) respectively. Number of theoretical plates as high as 280,000 plates/m were obtained for peptides mixture at optimum elution condition. Separation performance of the developed column was compared with commercial Ascentis Express RP-Amide column and it was observed that separation performance of PMP column was better than commercial column in terms of separation efficiency and resolution.

Molecular Mechanisms Responsible for In Vitro Cytotoxic Attributes of Conyza bonariensis Extract against Lymphoblastic Leukaemia Jurkat Cells.

BACKGROUND: Conyza bonariensis is known to have anti-cancer properties. OBJECTIVE: The current study investigated the in vitro pro-apoptotic properties of Conyza bonariensis (C. bonariensis) towards human lymphoblastic leukemia Jurkat cells. METHODS: Ariel parts of C. bonariensis were macerated in a non-polar (n-Hexane) solvent. MTS cell viability assay was employed to determine the cytotoxic activity of the extract towards human leukemia Jurket cells and normal Peripheral Blood Mononuclear Cells (PBMCs). The phytochemical composition of the extract was screened using HPLC method. Flow cytometric studies (FACS) were conducted to explore the pro-apoptotic potential of the extract. Western blot studies were employed to identify the molecular targets involved in the induction of apoptosis. RESULTS: The n-hexane extract showed selective cytotoxic activity towards Jurkat cells. FACS analysis indicated that the extract induced early and late apoptosis in Jurkat cells. Western blot studies revealed that the extract downregulated the expression of DNMT1, SIRT1, and UHRF1 with a simultaneous up-regulation of p73 and caspases-3 proteins expression. HPLC characterization of the extract revealed the presence of phenolic compounds. CONCLUSION: Overall, these findings demonstrate that the anti-cancer effects of a Conyza bonariensis extract towards human lymphoblastic leukemia Jurkat cells are due to the modulation of the activity of multiple oncogenic and tumor suppressor proteins. Phenolic contents of the extract are proposed to be responsible for these activities.

A network pharmacology approach to assess Reno-protective and -curative effects of methanolic extract of Malva neglecta Wallr in gentamicin induced renal toxicity rat model

Abstract The aim of present study was to explore protective and curative effects of Malve neglecta on kidneys. In silco study with network pharmacology was performed to find out potential target organs, genes and cellular cell lines which confirmed kidneys as target organ of phyto-constituents present in Malva neglecta extract. Gentamicin (40 mg/kg, i.p) was given to induce renal toxicity. Prophylactic study was performed with 300-, 600- and 900 mg/kg doses to find out nephro-protective and -curative effects and curative potential was evaluated at 900 mg/kg dose. Renal function biomarkers, blood urea, BUN, serum creatinine and uric acid, and oxidative stress measuring biomarkers, SOD, CAT, GSH and MDA levels in kidney homogenate were quantified at the end of study. Treatment groups showed decrease in blood urea, BUN, serum creatinine and uric acid levels dose dependently and curative group also showed decline in these biomarkers. SOD, CAT, GSH levels were increased and MDA level decreased in treatment groups significantly as compared to toxic control which revealed the role of oxidative stress in renal damage and anti-oxidant power of MN. Data suggested that use of MN along with drugs causing renal toxicity may prove beneficial due to its nephro- protective and curative effects.

Colorimetric Detection of Organophosphate Pesticides Based on Acetylcholinesterase and Cysteamine Capped Gold Nanoparticles as Nanozyme.

Organophosphates (OPs) are neurotoxic agents also used as pesticides that can permanently block the active site of the acetylcholinesterase (AChE). A robust and sensitive detection system of OPs utilising the enzyme mimic potential of the cysteamine capped gold nanoparticles (C-AuNPs) was developed. The detection assay was performed by stepwise addition of AChE, parathion ethyl (PE)-a candidate OP, acetylcholine chloride (ACh), C-AuNPs, and 3, 3', 5, 5'-tetramethylbenzidine (TMB) in the buffer solution. The whole sensing protocol completes in 30-40 min, including both incubations. The Transmission Electron Microscopy (TEM) results indicated that the NPs are spherical and have an average size of 13.24 nm. The monomers of C-AuNPs exhibited intense catalytic activity (nanozyme) for the oxidization of TMB, revealed by the production of instant blue colour and confirmed by a sharp peak at 652 nm. The proposed biosensor's detection limit and linear ranges were 5.8 ng·mL-1 and 11.6-92.8 ng·mL-1, respectively, for PE. The results strongly advocate that the suggested facile colorimetric biosensor may provide an excellent platform for on-site monitoring of OPs.

Age-Based Disparities in Metastatic Melanoma Patients Treated in the Immune Checkpoint Inhibitors (ICI) Versus Non-ICI Era: A Population-Based Study.

Immune checkpoint inhibitors (ICIs) have revolutionized metastatic melanoma treatment, but our knowledge of ICI activity across age groups is insufficient. Patients in different age groups with advanced melanoma were selected based on the ICI approval time in this study. Patients with melanoma were identified in the Surveillance, Epidemiology, and End Result (SEER) database program 2004-2016. The results showed that 4,040 patients had advanced melanoma before the advent of ICI (referred to as the "non-ICI era"), whereas there were 6,188 cases after ICI approval (referred to as the "ICI era"). In all age groups, the cases were dominated by men. The differences between the first (20-59 years) and second (60-74 years) age groups in both eras were significant in terms of surgery performance and holding of insurance policies (p = 0.05). The first and second groups (20-59 and 60-70 years old, respectively) showed no difference in survival (median = 8 months) during the non-ICI era, but the difference was evident in the first, second, and third age groups in the ICI era, with the younger group (20-59 years) having significantly better survival (median = 18, 14, and 10 months, respectively, p = 0.0001). Multivariate analysis of the first group (the youngest) in the ICI era revealed that surgery was significantly associated with an increase in survival among patients compared with those who did not undergo surgery (p < 0.0001). Furthermore, having an insurance policy among all age groups in the ICI era was associated with favorable survival in the first (20-59 years) and second (60-74 years) age groups (p = 0.0001), while there were no survival differences in the older ICI group (>74 years). Although there were differences in survival between the ICI era and the non-ICI era, these results demonstrate that ICI positively affected the survival of younger patients with advanced melanoma (first age group) than it had beneficial effects on older patients. Moreover, having had cancer surgery and holding an insurance policy were positive predictors for patient survival. This study emphasizes that adequate clinical and preclinical studies are important to enhance ICI outcomes across age groups.

The anti-cancer potential of 2,4,6 tris-methyphenylamino1,3,5-triazine compound against mammary glands cancer: Via down-regulating the hormonal, inflammatory mediators, and oxidative stress.

AIM OF THE STUDY: Breast cancer is caused by abnormal growth of the cells and progressed due to the over-expression of estrogen (ER) and progesterone (PR). The current study was designed to evaluate the anti-tumor activity of 2,4,6 tris-methyphenylamino1,3,5-triazine compound (MPAT) in N-nitroso, N-methyl urea (NMU)-induced mammary gland cancer. METHODS: Molecular docking and in-vitro studies were conducted before the in-vivo analysis. Female Albino rats were divided into 5 groups (n = 6). Group I received Carboxymethylcellulose (CMC) (1 mL/100 g). Group II (diseased group) received NMU 50 mg/kg. Group III (standard group) received tamoxifen (5 mg/kg). Group IV-V received MPAT at doses of 30 and 60 mg/kg respectively. All groups received NMU intraperitoneally except the control group at 3 weeks intervals for 12 weeks. After 12 weeks of NMU dosing, MPAT was given for 15 consecutive days. Biochemical, oxidative stress markers, hormonal profile, and inflammatory mediators were analyzed. KEY FINDINGS: MPAT showed significant interaction with the selected targets in docking studies. An over-expression of ER and PR was observed in NMU-treated rats which were restored significantly after MPAT administration. Nitrite and MDA levels were high in the diseased group and MPAT treatment attenuated the oxidative damage after treatment. Antioxidants such as superoxide dismutase (SOD), Catalase (CAT), total sulfhydryl (TSH), glutathione (GSH), and Lactate dehydrogenase (LDH) values were low in NMU-treated rats. SIGNIFICANCE: This study concluded that MPAT can be used as an anticancer agent due to its significant effects on down-regulating the hormonal profile and oxidative stress markers.

Genistein: An Integrative Overview of Its Mode of Action, Pharmacological Properties, and Health Benefits.

Genistein is an isoflavone first isolated from the brooming plant Dyer's Genista tinctoria L. and is widely distributed in the Fabaceae family. As an isoflavone, mammalian genistein exerts estrogen-like functions. Several biological effects of genistein have been reported in preclinical studies, such as the antioxidant, anti-inflammatory, antibacterial, and antiviral activities, the effects of angiogenesis and estrogen, and the pharmacological activities on diabetes and lipid metabolism. The purpose of this review is to provide up-to-date evidence of preclinical pharmacological activities with mechanisms of action, bioavailability, and clinical evidence of genistein. The literature was researched using the most important keyword "genistein" from the PubMed, Science, and Google Scholar databases, and the taxonomy was validated using The Plant List. Data were also collected from specialized books and other online resources. The main positive effects of genistein refer to the protection against cardiovascular diseases and to the decrease of the incidence of some types of cancer, especially breast cancer. Although the mechanism of protection against cancer involves several aspects of genistein metabolism, the researchers attribute this effect to the similarity between the structure of soy genistein and that of estrogen. This structural similarity allows genistein to displace estrogen from cellular receptors, thus blocking their hormonal activity. The pharmacological activities resulting from the experimental studies of this review support the traditional uses of genistein, but in the future, further investigations are needed on the efficacy, safety, and use of nanotechnologies to increase bioavailability and therapeutic efficacy.

Therapeutic role of Typha elephantina leaves aqueous extract in paracetamol intoxicated rabbits.

Present study is aimed to investigate the hepatoprotective and hematopoietic effect of Typha elephantina leaves aqueous (T.E.AQ), extract in paracetamol (PCM) intoxicated rabbits. Experimental animals were divided into various groups. The blood was taken on day 7th (W1=Week 1), day 14th (W2 = week 2) and day 21st (W3 = week 3) of treatments and was analyzed for all hematological and serum biochemical markers. PCM administration caused marked increase in the levels of serum biochemical and hematological parameters. The leaves of T.E.AQ extract at dose rate 300mg/kg body weight significantly (P<0.05) reduced the elevated levels of serum biochemical and hematological indices towards normal values on third week (day 21st) of treatment while treatment in the first two weeks revealed non-significant effects even at all doses of extract. The levels of glutathione (GSH) and radical scavenging activity (RSA) were reduced and thiobarbituric acid reactive substances (TBARS) levels was high in the PCM feed animals. Administration of (T.E.AQ) extract at high dose (300mg/kg) significantly regulated and normalized these antioxidant values. The antioxidant capacity of (TE.AQ) extract, showed increase inhibition against various extract concentrations on the basis of percent scavenging of (DPPH) free radical. The histological sections of liver further supported the hepatoprotective activity of extract.

Latcripin-7A from Lentinula edodes C91-3 induces apoptosis, autophagy, and cell cycle arrest at G1 phase in human gastric cancer cells via inhibiting PI3K/Akt/mTOR signaling.

Gastric cancer (G.C) is one of the most lethal cancer types worldwide. Current treatment requires surgery along with chemotherapy, which causes obstacles for speedy recovery. The discovery of novel drugs is needed for better treatment of G.C with minimum side effects. Latcripin-7A (LP-7A) is a newly discovered peptide extracted from Lentinula edodes. It is recently studied for its anti-cancer activity. In this study, LP-7A was modeled using a phyre2 server. Anti-proliferation effects of LP-7A on G.C cells were examined via CCK-8, colony formation, and morphology assay. Apoptosis of LP-7A treated G.C cells was evaluated via Hoechst Stain, western blot and flow cytometry. Autophagy was assessed via acridine orange staining and western blot. The cell cycle was assessed via flow cytometry assay and western blot. Pathway was studied via western blot and STRING database. Anti-migratory effects of LP-7A treated G.C cells were analyzed via wound healing, western blot, and migration and invasion assay. LP-7A effectively inhibited the growth of G.C cells by inhibiting the PI3K/Akt/mTOR pathway. G.C cells treated with LP-7A arrested the cell cycle at the G1 phase, contributing to the inhibition of migration and invasion. Furthermore, LP-7A induced apoptosis and autophagy in gastric cancer cells. These results indicated that LP-7A is a promising anti-cancer agent. It affected the proliferation and growth of G.C cells (SGC-7901 and BGC-823) by inducing apoptosis, autophagy, and inhibiting cell cycle at the G1 phase in G.C cells.
