Our findings elucidate for the first time that CENPK is upregulated in GC and suggest that CENPK is an oncogene that promotes GC progression, which is consistent with the role of CENPK in other tumours, such as ovarian cancer,15 triple‐negative breast cancer16 and hepatocellular carcinoma.17 The gene discussed is CENPK; the disease is ovarian carcinoma.
