An Investigation of the Anticancer Mechanism of L. Extract Against Colorectal Cancer by Integrating a Network Pharmacological Analysis and Experimental Validation.

L. has exhibited various pharmacological effects, yet its anticancer activities against colorectal cancer (CRC) and underlying molecular mechanisms remain unclear. This study investigated the anticancer properties of an ethanol extract of L. (CSE) against CRC cells, focusing on the identification of bioactive compounds and their mechanisms of action. A network pharmacology analysis was conducted to identify potential CRC targets and bioactive compounds of CSE, using LC-MS for compound identification. The anticancer effects of CSE were then validated through in vitro and in vivo models of CRC. The network pharmacological approach identified 87 overlapping genes between CSE targets and CRC-related genes, with protein-protein interaction analysis highlighting 33 key target genes. CSE inhibited cell proliferation in human CRC cell lines, including HCT 116, KM12SM, HT-29, and COLO 205, and induced apoptosis via caspase 3/7 activation. Western blot analyses confirmed the modulation of critical signaling pathways, including STAT3, AKT, and mitogen-activated protein kinases. Furthermore, CSE significantly suppressed tumor growth in MC38 CRC-bearing mice. These findings suggest that CSE possesses substantial potential as a natural anticancer agent for CRC treatment, highlighting the need for further exploration in therapeutic development.
