CST1 and cancer: By using the Pan‐cancer analysis in the online starBase software (http://starbase.sysu.edu.cn/), we found that CST1 was highly expressed in the cancer tissues (n = 510) compared with the normal samples (n = 58) collected from patients with thyroid carcinoma (P < 0.05; Fig. 1A), which were validated by our real‐time qPCR (Fig. 1B) and western blot analyses (Fig. 1C,D; Fig. S1A–F).
