Abstract
- Abstract Aim Furowanin A (Fur A) is a flavonoid isolated from Millettia pachycarpa Benth. Studies show its potent anti-neoplastic effects against leukemia cells. The aim of the present study was to determine the potential therapeutic effect of Fur A against colorectal cancer (CRC), and elucidate the underlying mechanism. Material and methods Cell Counting Kit-8 (CCK-8) assay was used to determine cell, and TUNEL and Annexin-V/PI staining was used to detect apoptosis and the cell cycle distribution. The expression levels of specific proteins in the CRC cells were analyzed by Western blotting. A xenograft model was also established to evaluate the therapeutic effect of Fur A in vivo. Key findings Fur A suppressed proliferation, blocked cell cycle progression, induced apoptosis and promoted autophagy in CRC cells. Interestingly, Fur A-induced autophagy functioned not only as a survival mechanism against apoptosis but also intensified the cell cycle arrest in CRC cells. In addition, Fur A mediated its effects via the inactivation of the STAT3/Mcl-1 axis. Significance Fur A is a promising drug candidate for the treatment and prevention of CRC. [ABSTRACT FROM AUTHOR]
