( A ) Immunoblots depicting protein level alterations in β-catenin, SATB1 and SATB2 upon simvastatin treatment and mevalonate supplementation in HCT15 cells. Mevalonate supplementation resulted in the rescue of the protein levels of β-catenin and SATB1. ( B ) Relative transcript expression of β-catenin, SATB1 and SATB2 upon simvastatin treatment and mevalonate supplementation. No significant changes were observed in the transcript levels of any of these genes. ( C ) Relative levels of cholesterol upon mevalonate supplementation and simvastatin treatment in HCT-15 cells monitored by LC-MS analysis. Cholesterol level was reduced upon treatment with simvastatin or mevalonate and restored upon combined treatment with simvastatin plus mevalonate as compared to the untreated control. Biological replicates n = 3, ** p < 0.05, *** p < 0.005, ns is non-significant as per Students’ t -test analysis. ( D ) A model illustrating the impact of these two conditions on the feedback mechanism regulating cholesterol-responsive genes. The decreased cholesterol levels observed with mevalonate supplementation could be attributed to the feedback system, which suppresses cholesterol-responsive gene expression in the presence of excess mevalonate.
