FEZF1 and gastric cancer: To assess whether FEZF1-AS1expression was correlated with clinical pathological parameters and prognosis of gastric cancer, according to relative FEZF1-AS1 expression in tumor tissues, the 82 gastric patients were classified into two groups: the high FEZF1-AS1 group (n = 52, fold-change ≥2); and the low FEZF1-AS1 group (n = 30, fold-change < 2) (Fig. 2a).
