Evaluation of the Anticancer Effects of Warburgia salutaris Leaf Extracts: A Comparative Study of Both Liposomal-Encapsulated and Unencapsulated Extracts, with Mechanistic Insights into Apoptotic Signalling

Abstract

< 0.0195 mg/mL) with minimal toxicity toward Vero kidney cells and RAW 264.7 macrophages. Mechanistically, WSN induced rapid cytotoxicity with necrotic features, whereas WSE promoted regulated apoptosis. Apoptosis was validated by DAPI/PI staining, Annexin V/PI flow cytometry, mRNA expression levels of Bax, Bcl-2, and caspase-3 measured with RT-PCR and proteome profiling array, confirming activation of intrinsic and extrinsic pathways. Both extracts also reduced LPS-induced ROS production. LC-MS identified multiple bioactive phytochemicals. Overall, liposomal encapsulation enhanced therapeutic precision, stability, and selectivity cytotoxicity, supporting its development as a nanomedicine-based anticancer strategy.
