Evaluating the Anti-proliferative and Apoptotic Role of Atrial Natriuretic Peptide in Colon Cancer Cell Lines
Journal Title: International Journal of Experimental Research and Review - Year 2024, Vol 38, Issue 2
Abstract
The use of small peptides and conventional anticancer drugs is gaining importance in oncology as small peptides may help increase chemo or radiation sensitivity. The present study aimed to study the impact of atrial natriuretic peptide (ANP) in reducing colon cancer cell proliferation in primary and metastatic colon cancer cell lines. The proliferation of colon cancer cell lines (SW480 and SW620) was analysed by CCK-8 assay and cell damage was analyzed by lactate dehydrogenase activity. Catalase activity assay was performed to measure the oxidative stress and antioxidant defense mechanisms in SW480 and SW620 cell lines. Subsequently, up or downregulation of cancer-specific gene expression such as BAX, Caspase-3, BCL-2, CDK-6, and PCNA genes were assessed after the treatment of small peptide ANP in SW480 and SW620 colon cancer cell lines. The ANP treatment decreased the colon cancer cell proliferation, upregulated the apoptosis-related gene expression (Caspase-3, BAX), downregulated the anti-apoptotic gene (BCL-2) expression, and proliferation-related genes (CDK-6, PCNA) in SW480 and SW620 colon cancer cell lines, and the differences were found to be statistically significantly. Further, increased levels of catalase in the colon cancer cell lines after ANP-treatment suggested the therapeutic role of ANP. Subsequently, the LDH analysis showed the potential of ANP in inducing colon cancer cell damage. Collectively, the current study clearly shows that ANP is a potential molecule in reducing uncontrolled cancer cell growth. However, additional research using animal models and additional colon cancer cell lines is needed to validate its potential usage in clinical studies.
