Riboflavin deficiency decreases the abundance of apolipoprotein B-100 in HepG2 cells. Cells were cultured in riboflavin-deficient (3.1 nmol/L) and riboflavin-sufficient (532 nmol/L) media for 4 d. Apolipoprotein B-100 was quantified by Western blot analysis and gel densitometry. Inserts depict representative Western blot images. a,bBars not sharing the same letter are significantly different (P < 0.05; n = 4). Means ± SD are shown.
