  • Title: [Roles of STAT5 in hematopoietic regulation and blood diseases].
    Author: Zhao YZ, Yuan WP, Cheng T.
    Journal: Zhongguo Shi Yan Xue Ye Xue Za Zhi; 2012 Dec; 20(6):1496-500. PubMed ID: 23257461.
    Abstract:
    Signal transducer and activator of transcription 5 (STAT5) is an important transcription factor existing in the cytoplasm of various types of cells. Once activated, STAT5 dimers translocate into nucleus and bind to the corresponding DNA sequence to regulate the transcription of its target genes. There are two isoforms of STAT5: STAT5A and STAT5B with 96% sequence homology and are encoded by two closely related but different genes. Studies have shown that STAT5 can regulate the survival, proliferation, differentiation and death of hematopoietic cells. Furthermore, elevated activation of STAT5 was found in many malignant hematologic diseases and therefore raised the possibility that STAT5 may be used as a new therapeutic target for blood related diseases. This review discusses the regulatory role of STAT5 in hematopoietic cells and its effect on the occurrence and development of blood diseases.
