A promising approach to accelerating the development of innovative anti-cancer therapies involves the evaluation of natural plant compounds. In this study, we focused on examining the effects of Warbugia ugandensis (W. ugandensis) methanolic root and stem infusions on the activity of five target genes—COX-2, CASPS-9, Bcl-xL, Bcl2, and 5-LOX—using colorectal cancer (CRC) cell lines (Caco-2). The plant extracts were prepared for testing by dissolving them in dimethyl sulfoxide (DMSO) after undergoing a step-by-step extraction process. Caco-2 cells were then treated with different concentrations of the extracts, and RNA was extracted and purified for analysis. Our results demonstrated a dose-dependent relationship between the phytoconstituents of W. ugandensis and the overexpression of CASP9, along with the downregulation of COX-2, 5-LOX, Bcl-xL, and Bcl2 genes. This suggests that W. ugandensis acts as a potent natural inhibitor of CRC progression. Given the potential clinical benefits, we propose the use of W. ugandensis methanolic root and stem extracts as promising organic inhibitors for CRC tumorigenesis, with more in vitro studies warranted to validate and expand on our findings. Additionally, we recommend further studies to identify and characterize the specific metabolites in W. ugandensis that contribute to the modulation of pathways responsible for inhibiting CRC growth.
