Knockdown of stromal‐interacting molecule 1 (STIM1) suppresses proliferation in imatinib‐resistant gastrointestinal stromal tumors (GIST) cells. A and B, Knockdown efficiency of STIM1 in GIST‐T1‐R and GIST‐882‐R cells tested by quantitative RT‐PCR and western blotting, respectively. GADPH was used as the loading control. C, Cell growth curves detected by Cell Counting Kit‐8 proliferation assays at various time points. D, Macroscopic images of colonies formed by treated GIST cells. *P < .05
