Phlda3基因编码一个只有PH结构域的127个氨基酸的小蛋白,与肿瘤抑制、胰岛β细胞增殖、胰岛素分泌、糖耐量和肝脏损伤有关。然而,phlda3在血管发育中的作用尚不清楚。在这里,我们发现phlda3的过表达降低了血管母细胞标志物sc1、fl1和etsrp以及节间血管(ISV)标志物flk1和cdh5的表达水平,并扰乱了TG(flk1:gfp)和tg(fli1:gfp)斑马鱼的ISV发育。此外,在斑马鱼胚胎中,phlda3的过表达抑制了AKT的激活,而由phlda3过表达导致的ISV的发育缺陷可以被AKT的表达所逆转。这些数据表明,phlda3通过AKT信号对血管母细胞规范和ISV的发展起负调控作用。血管母细胞是一种多能祖细胞,可分化为造血细胞和内皮细胞。尽管已经确定了几个促进血管母细胞分化的因素,如aggf1、scl和etsrp,但大多数血管母细胞调控因子仍然未知。在这里,我们发现phlda3的过表达通过抑制AKT信号来损害血管母细胞的规格和节间血管的发育,这表明phlda3是血管母细胞规格的负调节因子。
The phlda3 gene encodes a small, 127 amino acid protein with only a PH domain, and is involved in tumor suppression, proliferation of islet β-cells, insulin secretion, glucose tolerance, and liver injury. However, the role of phlda3 in vascular development is unknown. Here, we show that phlda3 overexpression decreases the expression levels of hemangioblast markers scl, fli1 and etsrp and intersegmental vessel (ISV) markers flk1 and cdh5, and disrupts ISV development in tg(flk1:GFP) and tg(fli1:GFP) zebrafish. Moreover, phlda3 overexpression inhibits the activation of AKT in zebrafish embryos, and the developmental defects of ISVs by phlda3 overexpression were reversed by the expression of a constitutively active form of AKT. These data suggest that phlda3 is a negative regulator of hemangioblast specification and ISV development via AKT signaling. Hemangioblasts are multipotent progenitor cells that differentiate into hematopoietic and endothelial cells. Although several factors for hemangioblast differentiation, such as aggf1, scl and etsrp, were identified, most hemangioblast regulators remain unknown. Here, we show that overexpression of phlda3 impairs hemangioblast specification and development of intersegmental vessels by inhibiting AKT signaling, suggesting that phlda3 is a negative regulator of hemangioblast specification.
