"Activation of mTORC1 after feeding increases phosphorylation of ubiquitin-specific peptidase 20 (USP20) which stabilizes HMG-CoA reductase (HMGCR) and therefore promotes cholesterol synthesis."

reach
"This licenses USP20’s recruitment into the HMGCR complex and antagonizes its degradation, thereby stabilizing HMGCR and promoting cholesterol synthesis [133]."

reach
"USP20 stabilizes 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) to increase liver cholesterol biosynthesis, which aggravates metabolic disorders [14]."

reach
"In sum, these findings suggest that TBBPA enhances cholesterol synthesis by increasing USP20 protein levels, which in turn stabilizes the HMGCR protein."

reach
"USP20 was recruited to the HMGCR complex and antagonized its degradation, up-regulating cholesterol synthesis and converting absorbed glucose and other nutrients into cholesterol."
