Signal Transducer and Activator of Transcription (STAT)-A and STAT5B Differentially Regulate Human Mammary Carcinoma Cell Behavior

Increased signal transducer and activator of transcription (STAT)-5 activation has been reported in various malignancies including mammary carcinoma. However, it is only recently that potentially distinct roles of STAT5A and STAT5B in neoplasia have begun to emerge. Herein we systematically delineate the functions of STAT5A and ..
