Abstract
S100 binding protein A16 (S100A16) expression levels are closely associated with microRNA (miRNA) processing. Higher levels of S100A16 are reported during the progression of many cancers. Our study mainly
explored the interaction between S100A16 and miR-6884-5p in gastric cancer (GC). Quantitative real-time polymerase chain reaction (qRT-PCR) was used to determine the level of S100A16 and miR-6884-5p in GC tissues
and cell lines. The si-S100A16, pcDNA-S100A16, miR-6884-5p mimic or inhibitor was transfected into GC
cells, and the effects of S100A16 and miR-6884-5p on the proliferation, invasion, and epithelial–mesenchymal
transition (EMT) were explored by qRT-PCR and Western blot assays. Luciferase assays were performed to
validate S100A16 as an miR-6884-5p target in GC cells. In our study, we found that the level of miR-6884-5p
was significantly decreased and the expression of S100A16 was significantly increased in GC tissues and cell
lines. There was a close association between these changes. Knockdown of S100A16 significantly inhibited the
proliferation, invasion, and EMT of GC cells. The bioinformatics analysis predicted that S100A16 is a potential
target gene of miR-6884-5p, and the luciferase reporter assay confirmed that miR-6884-5p could directly target
S100A16. Introduction of miR-6884-5p to GC cells had similar effects to S100A16 silencing. Overexpression
of S100A16 in GC cells partially reversed the inhibitory effects of the miR-6884-5p mimic. miR-6884-5p
inhibited the proliferation, invasion, and EMT of GC cells by directly decreasing S100A16 expression.
