Immunoblotting of serum deprivation‐response protein (SDPR) in endometrioid carcinoma cells. A, SDPR protein levels in HEC1B, HEC108, HEC116, and SNG‐M cells. B, HEC‐1B and HEC‐108, ALDH‐hi cells showed higher levels of SDPR than that of ALDH‐lo cells. Equal protein loading was confirmed by quantifying β‐actin levels (input control). Data are representative of 3 independent experiments. We quantified the results using ImageJ. SDPR/β‐actin quotient of ALDH‐hi cells is expressed as 1. The relative quotient of ALDH‐lo cells is presented as the ratio to that of ALDH‐hi cells. Results are shown as the mean ± SE. Student's t test: *P < .05, **P < .01
