Effect of bitter melon juice on SREBP-1c mRNA expression. Differentiating preadipocytes treated with varying concentrations of BMJ (0.5% to 2%, v/v) demonstrate a significant reduction in SREBP-1c mRNA gene expression. Bar graphs depict the densitometry scans of SREBP gene amplicons (238-bp) and are expressed as a ratio to GAPDH amplicon (298-bp) intensity. Data are expressed as a percentage of the control (set as 100%) and the values represent the mean ± SE (n = 6) of three independent experiments analyzed in duplicate. a, b, cMean values with common letters do not differ (p < 0.05).
