“…In this study, FBN1 gene expression was first detected and showed a gradually increasing trend in normal gastric mucosa, chronic superficial gastritis, chronic atrophic gastritis, and gastric cancer tissues and showed strong expression in gastric cancer tissues. Chronic superficial gastritis and chronic atrophic gastritis are precancerous lesions of gastric cancer (16,17). The results suggested that FBN1 can be used as a marker to determine precancerous lesions of gastric cancer, which may be closely related to the progression of gastric cancer and the prognosis of patients.…”
