While small animal models have proven extraordinarily effective at exploring mechanisms, studies in large animal models are critically needed, as a bridge between rodent studies and human trials, and to develop new therapies. We have shown that insulin-like growth factor-1 (IGF-1) reduces atherosclerotic burden and promotes features of plaque stability in Apoe-/- mice and in Rapacz swine with familial hypercholesterolemia (FH pigs). Our novel findings indicate that IGF-1 reduces the number of senescent…
