Fig. 5From: Functional consequences of enhanced expression of STIM1 and Orai1 in Huh-7 hepatocellular carcinoma tumor-initiating cellsOrai1 protein expression in STIM1-OE EpCAM(+)CD133(+) cells. Shown are (a) Orai1 (33 kDa) bands in WB analysis and (b) cumulative data of Orai1 protein expression levels. Orai1 band intensities were determined according to Orai1/β-actin ratios.
