Stromal‐interacting molecule 1 (STIM1) overexpression is related to acquired imatinib resistance in gastrointestinal stromal tumors (GIST) patients. A, Scatterplots of relative STIM1 expression in GIST tissues and their matched nontumor counterparts. STIM1 expressions were calculated and are expressed as the STIM1/GADPH expression ratio (2^−ΔCT). B, Comparison of STIM1 expression levels between GIST tissues and corresponding nontumor tissues. C, Scatterplots of relative STIM1 mRNA expression levels in imatinib‐resistant and imatinib‐sensitive groups. D, Relative STIM1 protein expression levels in GIST tissues and corresponding non‐GIST tissues. **P < .01
