Effect of high glucose (HG) culture medium on Orai1 and STIM1 protein expression in MUS-M1 cells. Representative immunoblotting images (A) and summarized data (B,C) showing the expression levels of Orai1 (B) and STIM1 (C) proteins in MUS-M1 cells cultured in normal glucose (NG, 5.6 mM D-glucose + 20 mM α-mannitol) or HG (25 mM D-glucose) medium for 1, 3, and 7 days. Alpha-actin was used as a loading control. Values are shown as the mean ± SEM (n = 3); **, and *** denote P < 0.01, and P < 0.001, respectively. NS means non-significant, NG vs. HG on the same day.
