Additional file 1: Figure S1. of Prognostic value of protein inhibitor of activated STAT3 in breast cancer patients receiving hormone therapy

Expression patterns of protein inhibitor of activated signal transducers and activators of transcription 3 (PIAS3) was detected in a panel of breast cancer cell lines. Total PIAS3 was determined by immunobotting in various breast cancer cell lines and one normal breast epithelial cell line. PIAS3 expression levels were normalized to the levels of the corresponding β-actin protein. The Image J software was used to compare the expression levels of total PIAS3. ER: estrogen receptor; HME: human mammary epithelial cells. (PDF 73 kb)
