Figure 2. RFX6 regulates GPR68 expression in human β-cells.

Figure 2

EndoC-βH2 cells (a) and adult human islets (b) were transfected with control non-target siRNA (siNT) or siRNA targeting RFX6 (siRFX6). GPR68 expression was analyzed 72 h post transfection by RT-qPCR. Data are expressed as percentage of siNT transfected cells. (c–e) wtRFX6 and Mut506RFX6 (one-way ANOVA) (c), transactivation domain VP16- conjugated RFX6 (d) and transcriptional repression domain KRAB- conjugated RFX6 (e) were expressed in EndoC-βH2 cells using bicistronic constructs with IRES-EGFP. GFP+ve cells were FACS isolated 48 h post-transfection and GPR68 expression was analyzed by RT-qPCR. Data are mean ± SEM of 3–5 experiments. *p < 0.05; **p < 0.01; ***p < 0.001 and ns, not significant.
