查询词典 a group of

The transforming growth factor-β superfamily, a large group of highly conserved growth factors including TGF-βs, activins and BMPs, regulate a wide variety of cellular functions such as proliferation, differentiation, apoptosis and migration. Signals from these growth factors are transduced by a group of Smad proteins. To date, there are nine vertebrate Smads, including the receptor-activated Smads , Smadsl-3, 5 and 8, the common mediator Smad4 and Smad4β, and the inhibitory Smads, Smad6 and 7. Signaling is initiated when the ligand induces assembly of a heteromeric complex of type Ⅱ and type Ⅰ TGFβ receptors. Then R-Smads are directly phosphorylated by activated type I TGF-β receptors.

在多种SMADS中，SMAD5令我们产生兴趣，基于三个原因：1、Smad5基因敲除胚胎中发现卵黄囊的异位造血以及CFU-GM祖细胞数目增加，表明SMAD5可能是早期造血发育的负向调控基因。；2、应用反义核酸封闭Smad5可以逆转TGF-β对祖细胞增殖的抑制效应，表明它可能介导TGF-β信号转导，后者的异常，包括某些SMADS的功能异常，和白血病紧密相关；3、Smad5基因定位在人染色体5q21，此区域的缺失和急性髓系白血病和骨髓增生异常综合症相关，因此，Smad5被怀疑为白血病抑制基因。
