Selaginella doederleinii Hieron, a well-known traditional Chinese herbal remedy, yielded an ethyl acetate extract (SDEA) displaying encouraging anticancer activity. Although the effect of SDEA on human cytochrome P450 enzymes (CYP450) exists, its nature is still ambiguous. A study on the inhibitory action of SDEA and its four components (Amentoflavone, Palmatine, Apigenin, and Delicaflavone) on seven CYP450 isoforms was conducted to forecast herb-drug interactions (HDIs) and to lay the foundation for future clinical trials, utilizing the established LC-MS/MS-based CYP450 cocktail assay. For the purpose of building a dependable LC-MS/MS CYP450 assay cocktail, substrates suitable for the seven tested CYP450 isoforms were determined. The investigation also included determining the presence of Amentoflavone, Palmatine, Apigenin, and Delicaflavone, within the SDEA material. The validated CYP450 cocktail assay was then utilized to investigate the inhibitory potency of SDEA and four constituents concerning CYP450 isoforms. The SDEA study demonstrated a potent inhibitory effect on CYP2C9 and CYP2C8 enzymes (IC50 = 1 g/ml), while showing moderate inhibition against CYP2C19, CYP2E1, and CYP3A (IC50 < 10 g/ml). Amentoflavone, present at the highest concentration (1365%) among the four constituents, demonstrated the strongest inhibitory action (IC50 less than 5 µM), significantly affecting CYP2C9, CYP2C8, and CYP3A in the extract. Amentoflavone exhibited a time-dependent inhibitory effect on both CYP2C19 and CYP2D6. T‐cell immunity The concentration of apigenin and palmatine influenced their inhibitory activity. Apigenin exerted an inhibitory effect on the enzymes CYP1A2, CYP2C8, CYP2C9, CYP2E1, and CYP3A. Palmatine exerted an inhibitory influence on CYP3A, and a moderately weaker effect on CYP2E1's activity. Regarding Delicaflavone, a potential anti-cancer agent, no significant inhibitory effect was observed on CYP450 enzymes. The inhibitory effect of amentoflavone on SDEA's activity toward CYP450 enzymes highlights the importance of evaluating potential drug interactions, especially when amentoflavone or SDEA are co-administered with other clinical agents. Alternatively, Delicaflavone appears more promising for clinical use, given its minimal interference with CYP450 metabolic processes.
Thunder God Vine (Tripterygium wilfordii Hook f), a traditional Chinese herb, which contains the triterpene celastrol, shows promising activity against cancer. An indirect mechanism of celastrol's effect on hepatocellular carcinoma (HCC) was investigated in this study, focusing on the gut microbiota's role in regulating bile acid metabolism and downstream signaling cascades. We established an orthotopic rat HCC model, which then underwent comprehensive analysis, including 16S rDNA sequencing and UPLC-MS analysis. The results of the study confirmed celastrol's influence on gut bacterial populations, reducing Bacteroides fragilis, increasing levels of glycoursodeoxycholic acid (GUDCA), and ameliorating the symptoms of hepatocellular carcinoma (HCC). GUDCA was observed to inhibit cellular proliferation and cause a halt in the mTOR/S6K1 pathway-driven cell cycle progression, specifically within the G0/G1 phase, in HepG2 cells. Analysis via molecular simulations, co-immunoprecipitation, and immunofluorescence, further supported the finding that GUDCA binds to farnesoid X receptor (FXR), affecting its interaction with retinoid X receptor alpha (RXR). FXR's requirement for GUCDA to suppress HCC cell proliferation was verified through transfection experiments with a mutant FXR. Animal studies demonstrated that the dual therapy of celastrol and GUDCA counteracted the negative effects of celastrol monotherapy, enhancing body weight maintenance and improving survival rates in rats with hepatocellular carcinoma. This study's findings demonstrate a mitigating effect of celastrol on HCC, occurring, in part, through modulation of the B. fragilis-GUDCA-FXR/RXR-mTOR axis.
Pediatric neuroblastoma, a highly prevalent solid tumor affecting children, is estimated to account for approximately 15% of cancer-related mortality among children in the United States. Currently, various treatment modalities, such as chemotherapy, radiotherapy, targeted therapies, and immunotherapy, are being utilized clinically to address neuroblastoma. While therapy may initially be effective, resistance inevitably emerges after extended use, causing treatment failure and cancer recurrence. For this reason, the study of the processes that lead to therapy resistance and the creation of strategies for reversing it have become a critical need. Recent research has uncovered a correlation between neuroblastoma resistance and several genetic alterations and dysfunctional pathways. These molecular signatures represent potential targets for intervention in refractory neuroblastoma. impulsivity psychopathology Building upon these targets, a range of novel interventions for neuroblastoma patients has been brought into existence. This review investigates the intricate pathways of therapy resistance and highlights potential therapeutic targets, such as ATP-binding cassette transporters, long non-coding RNAs, microRNAs, autophagy, cancer stem cells, and extracellular vesicles. Enitociclib CDK inhibitor A summary of reversal strategies for neuroblastoma therapy resistance, gleaned from recent studies, has been compiled, detailing approaches targeting ATP-binding cassette transporters, the MYCN gene, cancer stem cells, hypoxia, and autophagy. This review explores novel approaches to optimizing neuroblastoma therapy against resistance, offering potential insights into future treatment directions that could enhance outcomes and extend patient survival.
Globally, hepatocellular carcinoma (HCC) is a prevalent malignancy characterized by poor outcomes, evident in high morbidity and mortality. HCC's solid tumor structure relies heavily on angiogenesis, which is not only a key driver of its progression but also presents a promising avenue for therapeutic intervention. The research we conducted examined the utilization of fucoidan, a sulfated polysaccharide readily abundant in edible seaweeds commonly eaten in Asian diets due to their many health advantages. Though fucoidan displays promising anti-cancer activity, its anti-angiogenic properties are still subject to exploration and confirmation. Fucoidan, in conjunction with sorafenib (a tyrosine kinase inhibitor targeting VEGFR) and Avastin (bevacizumab, an anti-VEGF monoclonal antibody), was investigated for its impact on HCC, both within laboratory cultures and living organisms. Fucoidan, when combined with anti-angiogenic medications in an in vitro environment utilizing HUH-7 cells, displayed a substantial synergistic effect, resulting in a dose-dependent decrease in HUH-7 cell viability. The scratch wound assay for assessing cancer cell motility indicated that treatments with sorafenib, A + F (Avastin and fucoidan), or S + F (sorafenib and fucoidan) resulted in consistent incomplete wound closure, with wound closure percentages significantly lower (50% to 70%) than the untreated control group (91% to 100%), as determined by one-way ANOVA (p < 0.05). The RT-qPCR data clearly showed that fucoidan, sorafenib, A+F, and S+F treatments significantly lowered the expression of the pro-angiogenic PI3K/AKT/mTOR and KRAS/BRAF/MAPK pathways by up to threefold, based on one-way ANOVA analysis (p<0.005), compared to the untreated control group. Cells treated with fucoidan, sorafenib, A + F, and S + F displayed a significant upregulation of caspase 3, 8, and 9 protein levels according to ELISA results, particularly the S + F group showing a 40-fold and 16-fold increase in caspase 3 and 8 protein levels respectively, relative to the untreated control (p < 0.005, one-way ANOVA). In the DEN-HCC rat model, H&E staining showed larger areas of apoptosis and necrosis in tumor nodules for rats receiving the combined therapies; immunohistochemical analysis of caspase-3 (apoptosis), Ki67 (proliferation), and CD34 (angiogenesis) exhibited remarkable enhancements with the application of the combined therapies. Although this report reveals encouraging chemo-modulatory effects of fucoidan when used with sorafenib and Avastin, more research is necessary to fully understand the possible beneficial or detrimental interactions between these agents.
