Transforming growth factor-β1 (TGF-β1) enhances high mobility group A1 (HMGA1) expression in MCF-7 and MDA-MB-231 cells. (A) qPCR analysis of HMGA1 expression induced by treatment with various concentrations of TGF-β1 for 9 h in MCF-7 and MDA-MB-231 cells. (B) qPCR analysis of HMGA1 expression induced by treatment with 5 ng/ml of TGF-β1 for the indicated periods of time. (C) Immunofluorescence staining of HMGA1 expression induced by treatment with various concentrations of TGF-β1 for 9 h in MCF-7 and MDA-MB-231 cells. *P<0.05 and **P<0.01, compared with the group not treated with TGF-β1.
