Additional file 1: Figure S1. of Invasion of ovarian cancer cells is induced byPITX2-mediated activation of TGF-β and Activin-A

The expression of PITX2 is up-regulated in human ovarian cancer. (A) The level of PITX2 was observed by IHC in human ovarian tissue-sections with specific antibody followed by Alexa Fluor-488 (green) of low malignant potential (i; n = 20) and high malignant potential metastatic adenocarcinoma patients (ii; n = 20). The DAPI-stained nuclei and the merged images were also shown. Scale bar, 10 μm. (TIFF 28495 kb)
