Abstract

MicroRNA-182 (miR-182) is significantly downregulated in human gastric tissue samples. Overexpression of miR-182 suppresses the proliferation and colony formation of gastric cancer cells. However, new aspects of the mechanism are still emerging in gastric cancer. ANUBL1, also known as ZFAND4 (zinc finger, AN1-type domain 4), its roles are scarely reported in cancer. In this study, we not only showed that ANUBL1 as an oncogene was upregulated and could promote proliferation of SGC-7901 cells, but also demonstrated that its over-expression led to a strong decrease of miR-182 expression and expression of ANUBL1 was in turn directly downregulated by miR-182, thereby establishing a negative feedback loop between miR-182 and ANUBL1. The elucidation of the mechanisms of miR-182 targeting ANUBL1 in gastric cancer helps us to further understand the mechanism of gastric cancer initiation and progression.
