A higher ratio of STIM1β/STIM1 (0.2–0.3 compared to 0.01–0.03 in astrocytes and non‐cancerous HEK293 cells) was noted in several cancer cell lines (Figure 1d), including U87 MG, SK‐N‐SH, Caco‐2, and A549 originated from glioblastoma, neuroblastoma, colorectal adenocarcinoma, and lung adenocarcinoma tissues, respectively. The gene discussed is STIM1; the disease is cancer.
