LINC01410-miR-532-NCF2-NF-kB feedback loop promotes gastric cancer angiogenesis and metastasis.

ABSTRACT: Dysregulation of non-coding RNAs, including miRNAs and lncRNAs has been reported to play vital roles in gastric cancer (GC) carcinogenesis, but the mechanism involved is largely unknown. Using the cancer genome atlas (TCGA) data set and bioinformatics analyses, we identified miR-532-5p as a potential tumor suppressor in GC, and found that lncRNA LINC01410 might be a negative regulator of miR-532-5p. We then conducted a series of in vivo and in vitro assays to explore the effect of LINC01410 on miR-532-5p-mediated GC malignancy and the underlying mechanism involved. MiR-532-5p overexpression inhibited GC metastasis and angiogenesis in vitro and in vivo, whereas miR-532-5p silencing had the opposite effect. Further study showed that miR-532-5p attenuated NF-κB signaling by directly inhibitin
