GV1001, hTERT Peptide Fragment, Prevents Doxorubicin-Induced Endothelial-to-Mesenchymal Transition in Human Endothelial Cells and Atherosclerosis in Mice.

ABSTRACT: Doxorubicin is a highly effective anticancer agent, but its clinical use is restricted by severe side effects, including atherosclerosis and cardiomyopathy. These complications are partly attributed to doxorubicin's ability to induce endothelial-to-mesenchymal transition (EndMT) in vascular endothelial cells, a critical process in the initiation and progression of atherosclerosis and cardiomyopathy. GV1001, a multifunctional peptide with anti-inflammatory, anti-cancer, antioxidant, and anti-Alzheimer's properties, has demonstrated inhibition of EndMT. We investigated whether GV1001 could counteract doxorubicin-induced EndMT in endothelial cells and prevent atherosclerosis in a mouse model. The results revealed that GV1001 significantly suppressed EndMT induced by doxorubicin, likely throug
