For example, Yeung et al confirmed that hypoxia stimulates STC1 gene expression in various human cancer cells including colon carcinomas, nasopharyngeal cancer cell lines (CNE‐2, HONE‐1 and HK‐1), and ovarian cancer cell lines (CaOV3, OVCAR3 and SKOV3).22 Here, STC1 is linked to nasopharyngeal carcinoma.
