Fig. 6From: Calcitriol downregulates fibroblast growth factor receptor 1 through histone deacetylase activation in HL-1 atrial myocytesChromatin immunoprecipitation (ChIP) assay of acetyl-histone H4 (Ac-H4) and histone deacetylase (HDAC) in the fibroblast growth factor receptor 1 (FGFR1) promoter in control and calcitriol-treated HL-1 cells. Representative image and average data (n = 6) of (a) histone H4 acetylation, and (b) HDAC1, HDAC2, and HDAC3 binding to the FGFR1 promoter from control and calcitriol (10 nM)-treated HL-1 cells. * p < 0.05, *** p < 0.005Back to article page
