a A schematic outline of the experimental design. b Effect of miR-567 silence on transplanted tumor growth from SKBR-3 cells. Representative images of tumors as indicated in left panel and tumor growth as indicated in right panel, *P < 0.05. c Effect of miR-567 overexpression on transplanted tumor growth from SKBR-3-TR cells. Representative images of tumors as indicated in the left panel and tumor growth as indicated in the right panel, *P < 0.05. d Representative images of tumor samples derived from SKBR-3 cells that were stained with Ki67 by immunohistochemistry (IHC, left panel) and quantified (right panel); scale bars: 50 μm, **P < 0.01 compared with control inhibitor. e Representative images of tumor samples derived from SKBR-3-TR cells that were stained with Ki67 by IHC (left panel) and quantified (right panel); scale bars: 50 μm, **P < 0.01 compared with control mimics.
