果蝇无翅(Wg)是一种在发育过程中决定细胞命运的形态因子。先前的研究表明,内吞途径调节了Wg的运输和信号传导。在这里,我们发现vamp7(一个囊泡融合所需的基因)的缺失会显著增加Wg水平并减少Wg信号。有趣的是,我们发现Dally-like (Dlp)的水平在vamp7突变细胞中也增加了,Dlp是一种可以与Wg相互作用以抑制果蝇翅膀后腹边界的Wg信号的glytypican。rab4依赖性再循环核内体中wppuncta呈Dlp阳性。我们假设VAMP7是细胞内转运Wg所必需的,并且在依赖rab4的循环内体中积累Wg可能会影响Wg信号传导。
Drosophila Wingless (Wg) is a morphogen that determines cell fate during development. Previous studies have shown that endocytic pathways regulate Wg trafficking and signaling. Here, we showed that loss of vamp7, a gene required for vesicle fusion, dramatically increased Wg levels and decreased Wg signaling. Interestingly, we found that levels of Dally-like (Dlp), a glypican that can interact with Wg to suppress Wg signaling at the dorsoventral boundary of the Drosophila wing, were also increased in vamp7 mutant cells. Moreover, Wg puncta in Rab4-dependent recycling endosomes were Dlp positive. We hypothesize that VAMP7 is required for Wg intracellular trafficking and the accumulation of Wg in Rab4-dependent recycling endosomes might affect Wg signaling.
