Abstract

The aim of this study was to investigate the role of far upstream element-binding protein 1 (FUBP1) in gastric cancer development. Using immunohistochemistry, we detected FUBP1 expression in 18 chronic superficial gastritis patients, 33 chronic atrophic gastritis patients, 21 moderate and severe gastric dysplasia patients, and 31 gastric cancer patients. FUBP1 mRNA expression in gastric cancer tissue and paraneoplastic tissue was measured with fluorescent quantitative reverse transcription polymerase chain reaction. The FUBP1 expression rates in the chronic atrophic gastritis, moderate and severe dysplasia, and gastric cancer patients were 51.51% (17/33), 76.19% (16/21), and 90.32% (28/31), respectively; these were higher than the expression rate of the chronic superficial gastritis patients (11.11%, 2/18). FUBP1 expression in the gastric cancer patients was significantly higher than that in the chronic atrophic gastritis patients. The relative amount (0.2593 ± 0.1209) of FUBP1 mRNA in the gastric cancer tissue was higher than that in paraneoplastic tissue (0.1969 ± 0.0211) (p < 0.05). There was a statistically significant correlation between overall survival rates and age, sex, lymph node metastasis, and distant metastasis (p < 0.05). FUBP1 expression differs among gastric tissues. There is a correlation between overall survival rates and age, sex, lymph node metastasis, and distant metastasis.
