Summary: | Cell proliferation and differentiation are the foundation of reproduction and growth. Mistakes in these processes may affect cell survival, or cause cell cycle dysregulation, such as tumorigenesis, birth defects and degenerative diseases, or cell death. Myeloid ecotropic viral integration site 1 (MEIS1) was initially discovered in leukemic mice. Recent research identified MEIS1 as an important transcription factor that regulates cell proliferation and differentiation during cell fate commitment. MEIS1 has a pro-proliferative effect in leukemia cells; however, its overexpression in cardiomyocytes restrains neonatal and adult cardiomyocyte proliferation. In addition, MEIS1 has carcinogenic or tumor suppressive effects in different neoplasms. Thus, this uncertainty suggests that MEIS1 has a unique function in cell proliferation and differentiation. In this review, we summarize the primary findings of MEIS1 in regulating cell proliferation and differentiation. Correlations between MEIS1 and cell fate specification might suggest MEIS1 as a therapeutic target for diseases. |
