骨形态发生蛋白(BMPs)在发育和疾病中起着关键作用,调节背腹模式、腭形成和骨化等多种过程。这些配体通常被认为通过BMP受体特异性Smad蛋白1、5和8发出信号。为了确定Smad1/5/8活性的时空模式,从而确定发育中的斑马鱼胚胎中典型的BMP信号传导,我们在BMP响应元件的控制下产生了表达EGFP的转基因系。EGFP在许多已建立的BMP信号域中表达,并响应BMP I型受体活性和smad1和smad5表达的改变。这种转基因Smad1/5/8报告系将有助于确定BMP活性特定区域的配体和受体需求,以及用于鉴定典型BMP信号传导增强或抑制的遗传和药理学筛选。
Bone morphogenetic proteins (BMPs) are critical players in development and disease, regulating such diverse processes as dorsoventral patterning, palate formation, and ossification. These ligands are classically considered to signal via BMP receptor-specific Smad proteins 1, 5, and 8. To determine the spatiotemporal pattern of Smad1/5/8 activity and thus canonical BMP signaling in the developing zebrafish embryo, we generated a transgenic line expressing EGFP under the control of a BMP responsive element. EGFP is expressed in many established BMP signaling domains and is responsive to alterations in BMP type I receptor activity and smad1 and smad5 expression. This transgenic Smad1/5/8 reporter line will be useful for determining ligand and receptor requirements for specific domains of BMP activity, as well as for genetic and pharmacological screens aimed at identifying enhancers or suppressors of canonical BMP signaling.
