Statin therapy inhibits Fatty Acid Synthase via dynamic protein modifications

ABSTRACT: Recent discoveries revealed HMG-CoA is a reactive metabolite that can non-enzymatically modify proteins and impact their activity. Therefore, we predicted that inhibition of HMGCR by statins might increase HMG-CoA levels and protein modifications. Upon statin treatment, we observed a strong increase in HMG-CoA levels, and only a single protein was modified. Mass spectrometry revealed fatty acid synthase (FAS) was modified on active site residues and, importantly, the modification is located on non-lysine side-chains.

Statins are a class of drug widely prescribed for the prevention of cardiovascular disease, with pleiotropic cellular effects. Statins inhibit HMG-CoA reductase (HMGCR), which converts the metabolite HMG-CoA into mevalonate. Recent discoveries have shown HMG-CoA is a reactive metabolite that can non-enzymatically modify proteins and impact their activity. Therefore, we predicted that inhibition of HMGCR by statins might increase HMG-CoA levels and protein modifications. Upon statin treatment, we ...[more]
