The expression of miR-561 is down-regulated in GC cell lines. A. Down-regulation of miR-561 expression in GC cell lines (SGC-7901, HGC-27, MKN-45, MGC-803) compared with the corresponding controls. Relative expression of miR-561 in four GC cell lines and one normal gastric epithelial-1 cells (GES) was determined by qRT-PCR. U6 snRNA was used as internal control. B. Northern blot analysis of miR-561 expression in four GC cell lines and one normal gastric epithelial-1 cells (GES). U6 was also detected as a loading control.
