Abstract

Gastric cancer is a serious threat to human health. Nuclear receptor subfamily 1 group D member 1 (REV‑ERBα) is a member of the nuclear hormone receptor family that regulates lipid metabolism, inflammatory responses and circadian rhythms. However, the role of REV‑ERBα in the pathogenesis of human gastric cancer is unclear. The present study employed gastric cancer tissues from 74 patients and determined the association between REV‑ERBα expression with clinicopathological variables and prognosis. Furthermore, the association between REV‑ERBα and apoptosis in undifferentiated and moderately differentiated human gastric cancer cells was determined. It was identified that REV‑ERBα expression was decreased in gastric cancer, which was positively associated with poor differentiation (P=0.009), T stage (P=0.001), Tumor‑Node‑Metastasis (TMN) stage (P=0.001) and lymph node metastasis (P=0.007). In the survival analysis, the 3‑ and 5‑year survival times of patients were significantly associated with REV‑ERBα expression (P=0.009 and P=0.002, respectively). Low REV‑ERBα expression was associated with poor prognosis (P<0.05). Concurrently, cleaved caspase‑3 expression was downregulated, whereas expression levels of Bcl‑2 and the Bcl‑2/Bax ratio were upregulated in gastric cancer tissues compared with normal tissues. REV‑ERBα activator GSK4112 caused apoptosis in SGC‑7901 and BGC‑823 cell lines. REV‑ERBα levels were decreased in human gastric cancer, which was associated with poor differentiation, TMN stages and poor prognosis. REV‑ERBα is a potential biomarker for tumor development and prognosis, and a potential therapeutic target for gastric cancer.
