BRMS1 performs an anti-tumor effect on renal cell carcinoma via inhibition of PI3K/AKT/mTOR signaling pathway

Objective:To explore the anti-tumor of breast cancer metastasis suppressor 1(BRMS1)on renal cell carcinoma.Methods:BRSM1 stabilized overexpressed and knockdown cell models were constructed to detect the effect of BRMS1 overexpression and knockdown on viability rate of 769-P cells.Activation of PI3K/AKT-mTOR-NFκB signaling pathway,expression of cellular apoptosis-related proteins,DNA damage repair-related proteins and angiogenesis-related proteins were detected using Western blotting analysis.Results:The viability rate of 769-P cells were significantly decreased in BRMS1 overexpression cells while significantly increased in BRMS1 knockdown cells(P<0.05).The activity of PI3K/AKT-mTOR-NFκB signaling pathway was significantly inhibited with BRMS1 overexpression(P<0.05),and expression of BAX was significantly increased with significantly decreased expression of Bcl-2(P<0.05).Besides,BRMS1 overexpression could significantly decrease the expression of DNA damage repair-related proteins and angiogenesis and cell-matrix degradation related proteins(P<0.05).Conclusion:BRMS1 induces apoptosis of renal cell carcinoma and performs an anti-tumor effect via inhibition of PI3K/AKT-mTOR-NFκB signaling pathway,expression of DNA damage repair-related proteins and angiogenesis-related proteins.

Therapeutic targets of Traditional Chinese Medicine for colorectal cancer

OBJECTIVE: To explore the role of Traditional Chinese Medicine(TCM) in the prevention and treatment of colorectal cancer and identify possible therapeutic targets of TCM to provide clues for the use of TCM for colorectal cancer prevention and treatment in the clinic and to find novel directions for new drug discovery for colorectal cancer.METHODS: We used Pub Med and Google to search for and collect scientific publications for a full evaluation of current evidence in the literature indicating the potential role of Chinese herbal medicines and their respective ingredients as effective candidatesforcolorectalcancerpreventionandtreatment.RESULTS: We extracted a detailed description of potential therapeutic Chinese herbal medicines and their constituent ingredients that target different mechanisms in colorectal cancer such as gene mutation, dysregulation of signaling pathways, metabolism disorders, and the inflammatory microenvironment, including both conventional and non-conventional approaches.CONCLUSION: TCM may be a promising complementary and alternative therapy for the treatment of colorectal cancer.
