The expression of MiR-128b is significantly down-regulated in GC tissues and cell lines.
Ectopic expression of miR-128b directly affects cell proliferation, migration and invasion in vitro.
Overexpression of miR-128b increases apoptosis in GC cells.
A2bR is a candidate target gene of miR-128b.
MiR-128b represses cell proliferation, migration and invasion and promotes apoptosis by targeting A2bR in GC.
