Involvement of the MicroRNA-1-LITAF Axis in Gastric Cancer Cell Growth and Invasion

Anticancer Res. 2020 Nov;40(11):6247-6256. doi: 10.21873/anticanres.14645.

Abstract

Background/aim: Lipopolysaccharide-induced tumor necrosis factor alpha factor (LITAF) has been identified as a tumor suppressor in human cancers. Present study, we assessed biological role of LITAF in human gastric cancer.

Materials and methods: The clinical impacts of LITAF expression were assessed in gastric cancer using public databases. The biological role of LITAF was assessed in gastric cancer cells using siLITAF transfection.

Results: High LITAF expression was correlated well with worse prognosis, including pathological stage (p=0.034) and pathological T stage (p=0.047), as well as with shorter survival. Herein, we present a novel finding that miR-1-3p could inhibit LITAF expression by directly binding to the 3'-untranslated region of LITAF mRNA. Cell functional assays revealed that LITAF knockdown could significantly suppress gastric cancer growth and motility.

Conclusion: High LITAF expression resulting from low miR-1-3p expression is a biomarker for poor prognosis or therapeutic targets in gastric cancer.
