High Throughput NPY-Venus and Serotonin Secretion Assays for Regulated Exocytosis in Neuroendocrine Cells

[Abstract]  Here we describe two assays to measure dense core vesicle (DCV) exocytosis-mediated cargo secretion in neuroendocrine cells. To conduct siRNA screens for novel genes in regulated DCV exocytosis, we developed a plate reader-based secretion assay using DCV cargo, NPY-Venus, and an orthogonal 3H-serotonin secretion assay. The NPY-Venus secretion assay was successfully used for a high throughput siRNA screen, and the serotonin secretion assay was used to validate hits identified from the screen (Sorensen, 2017; Zhang et al., 2017). [摘要]  在这里我们描述了两种测定方法来测量神经内分泌细胞中的致密核心囊泡(DCV)胞吐作用介导的货物分泌。 为了在受调控的DCV胞吐作用中对新基因进行siRNA筛选,我们开发了使用DCV货物,NPY-金星以及正交3H-血清素分泌测定的基于读板器的分泌测定法。 NPY-金星分泌测定成功地用于高通量siRNA筛选,并且使用血清素分泌测定来验证从筛选中鉴定的命中(Sorensen,2017; Zhang等人,2017)。


【背景】致密核心囊泡(DCV)胞吐作用介导内分泌和神经内分泌细胞分泌蛋白质,肽和小分子。当蛋白质和肽激素被内质网上的核糖体合成时,蛋白质和肽激素进入分泌途径,并在跨高尔基网络(TGN)(Borgonovo等人,2006; Bowman等, >等人,2009)。小分子物质,如5-羟色胺,直接被胞质单胺转运蛋白(VMATs)从细胞质直接吸收到DCV的内腔(Sudhof,2004)。在非刺激条件下,货物分子被储存在靠近质膜的DCV内。当细胞接受增加细胞质Ca ...

[Abstract]  This is a protocol to detect HIV-1 reverse transcription products in cytoplasmic and nuclear fractions of cells infected with VSV-G-pseudotyped envelope-defective HIV-1. This protocol can also be extended to HIV-1 with regular envelope.
