Effect of 1,25(OH)2D on GOT1 Expression. MCF10A-ras cells were treated with vehicle or 1,25(OH)2D (10 nM). (A) ME1 expression was measured after 96 h of treatment using qRT-PCR and normalized to 18S. (B) GOT1 mRNA expression was measured after indicated hours of treatment using qRT-PCR and normalized to 18S. (C) GOT1 protein expression was measured after indicated hours of treatment and normalized to actin. Values are presented relative to vehicle treated cells at each time point and representative images are shown for each time point. (D) GOT1 mRNA expression was measured after cell transfection with a pCMV6-Neo or GOT1 expressing plasmid and 96 h vehicle or 1,25(OH)2D treatment. (E) NEO and GOT1 transfected MCF10A-ras cells were treated with vehicle or 1,25(OH)2D for 96 h with a concurrent H2O2 challenge (100 μM) for the last 24 h. Values are expressed as mean ± S.E.M. Asterisk (*) indicates significant difference from vehicle treatment (P < 0.05). Bars with different letters are significantly different (P < 0.05).
