Functional analyses of the rs28514894 SNP in luciferase reporter gene transfections in HepG2 (A) and JEG3 (B) cells. HepG2 and JEG3 cells were transiently co-transfected with either the empty basic-pGL3 (O) or the pGL3-LXRβ*T allele or the pGL3-LXRβ*C allele vector with or without an HNF4α or NF1s expression vector. Activity was expressed as fold activity compared with the pGL3-LXRβ*T vector and the empty basic-pGL3 vector. White and black bars represent activities obtained without or with HNF4α or NF1s, respectively. Each bar represents the means ± SEM of at least 3 independent experiments. Firefly luciferase activities were normalized against renilla luciferase activities. Data were compared using the Kruskal-Wallis non-parametric test. *p < 0.05, ** p < 0.01.
