A Scorpion Peptide Exerts Selective Anti-Leukemia Effects Through Disrupting Cell Membranes and Triggering Bax/Bcl-2-Related Apoptosis Pathway.

ABSTRACT: Numerous modern scientific studies have demonstrated that animal venoms harbor a wealth of diverse anticancer active components, serving as a valuable resource for the development of natural antitumor drugs. AI-based computation and prediction models enable rapid screening of extensive active peptides. In this study, the anticancer activity of seven peptides was predicted using our previous deep learning model. Further verification experiments confirmed that Lpep3 can selectively and efficiently inhibit the growth of leukemia cells. Electron microscopy observations revealed cell shrinkage in morphology and honeycomb-like perforations on the cell membrane in the treated group. It is hypothesized that high-concentration peptides disrupt the cell membrane and increase cell permeability, which
