Knockdown of HOXD8 promotes the proliferation, migration and invasion of MCF-7 breast cancer cells. (A) Transfection efficiency of shRNA-HOXD8 was determined using western blotting. Cell proliferation was analyzed using (B) Cell Counting Kit-8 and (C and D) colony formation assays following knockdown of HOXD8. (E and F) Cell migration was determined using a wound healing assay. (G and H) Cell invasion was measured using a Matrigel Transwell assay. (I) MMP2 and MMP9 protein expression was analyzed using western blotting. ^*P<0.05, ^**P<0.01 and ^***P<0.001 vs. shRNA-NC; n≥3. Scale bar, 100 µm. HOXD8, homeobox D8; NC, negative control; shRNA, short hairpin RNA.
