IGF2 产生的微小核糖核酸通过抑制 IGF1 限制生长
胰岛素样生长因子1(IGF1)是一种关键蛋白质,有助于控制生物体出生后和发育期间的体型,而IGF2则是胎儿发育期间生长和体型的主要调节因子。细胞报告》(Cell Reports)上的一项研究描述了由Igf2产生的一种微RNA调节IGF1以抑制小鼠生长的机制,研究人员随后评估了miR-483对胎儿和出生后发育和生长的影响。"通讯作者米格尔-康斯坦西亚(Miguel Constância)说:"我们制造了一种基因敲除小鼠和两种小鼠品系,它们制造的miR-483拷贝数比正常水平要多;一种来自Igf2基因的'内源性'位置,另一种来自另一个基因组位置。敲除miR483(Mir483Pat-KO小鼠)不会导致明显的表型变化。然而,在胎儿发育过程中,Mir-483的过度表达普遍导致胎儿死亡。

期刊介绍: Chemical Research in Toxicology publishes Articles, Rapid Reports, Chemical Profiles, Reviews, Perspectives, Letters to the Editor, and ToxWatch on a wide range of topics in Toxicology that inform a chemical and molecular understanding and capacity to predict biological outcomes on the basis of structures and processes. The overarching goal of activities reported in the Journal are to provide knowledge and innovative approaches needed to promote intelligent solutions for human safety and ecosystem preservation. The journal emphasizes insight concerning mechanisms of toxicity over phenomenological observations. It upholds rigorous chemical, physical and mathematical standards for characterization and application of modern techniques.
