激活转录因子5 (ATF5)是各种组织发育所必需的,特别是在应激条件下。ATF5功能障碍已被证明与许多疾病有关。ATF5的确切功能是组织特异性的,其在红细胞生成中的作用尚不清楚。我们采用功能缺失策略来研究ATF5在小鼠红细胞生成中的作用。我们发现Atf5基因的敲低会损害胎儿肝红系祖细胞的增殖。此外,ATF5缺乏抑制了红系分化。我们的研究表明,ATF5可能是一个潜在的治疗靶点,治疗血液疾病无效的红细胞生成。
Activating transcription factor 5 (ATF5) is necessary for the development of various tissues, particularly under stress. Dysfunctions of ATF5 have been shown to be involved in many diseases. The exact function of ATF5 is tissue-specific, and its role in erythropoiesis is still unknown. We here employed the loss of function strategy to investigate the role of ATF5 in murine erythropoiesis. We found that knockdown of Atf5 impaired the proliferation of fetal liver erythroid progenitors. Furthermore, erythroid differentiation was inhibited by ATF5 deficiency. Our study suggests that ATF5 may be a potential therapeutic target for treating blood diseases with ineffective erythropoiesis.
