Furthermore, we found that the increased fecal fat excretion was associated with decreased fecal bile acid excretion, suggesting that a decrease in bile acid production

This over- view highlights the current knowledge gap in the molecular regulation of the intracellular LDLR trafficking pathway, and we suggest that filling this gap may help to

Autosomal recessive hypercholesterolemia (ARH) might also play a role in directing LDLR from the endosomes to recycling vesicles, as demonstrated for the LDLR family member

In addition, LRP1 controls cellular cholesterol efflux by modulating the expression of ABCA1 and ABCG1, and hepatic LRP1 protects against diet-induced hepatic insulin

Although the total protein levels of hepatic LDLR and LRP1 in WT and ApoE3*L mice are not affected upon CCC inactivation, this study and our previous work (8) showed that

Hepatic WASH/LDLR deficiency mimics the plasma lipid phenotype in hepatic LRP1-deficient mice with an Ldlr knockout background (27), suggesting that the WASH complex is also

Cyp7a1 catalyzes the first and rate-limiting step in the conversion of cholesterol into bile acids in mice (30); however, decreased Cyp7a1 expression in Washc1 depleted
