缺乏必需基因的胚胎可能表现出复杂的表型,反映了编码蛋白质的多效性功能和非细胞自主需求。嵌合动物的产生,其中大多数细胞是野生型,但少数细胞是突变型,是一种强大的工具,可以在细胞和亚细胞分辨率下详细分析特定细胞类型中基因的细胞自主功能。在这里,我们将此方法应用于果蝇脑海绵状血管瘤 3 (CCM3) 通路的分析。保守的 CCM3 蛋白与其结合伴侣生发中心激酶 III(果蝇中的 Wheezy/GckIII,人类中的 MST3、STK24 和 STK25)一起在管形态发生的调节中发挥作用(Bergametti 等人,Am J Hum Genet. 76:42-51,2005 年;J Cell Sci,123:1274-1284,2010 年;Guclu 等人,2005 年;Lant 等人,6:6449,2015 年。 25:507–519, 2013; Ceccarelli et al.

Embryos deficient for an essential gene may show complex phenotypes that reflect pleiotropic functions and non-cell-autonomous requirements for the encoded protein. The generation of mosaic animals, where most cells are wild type, but a few cells are mutant, is a powerful tool permitting the detailed analysis of the cell autonomous function of a gene, in a particular cell type, at cellular and subcellular resolutions. Here we apply this method to the analysis of the Cerebral Cavernous Malformations 3 (CCM3) pathway inDrosophila.The conserved CCM3 protein functions together with its binding partner, Germinal Center Kinase III (Wheezy/GckIII inDrosophila, MST3, STK24, and STK25 in human) in the regulation of tube morphogenesis (Bergametti et al. Am J Hum Genet. 76:42–51, 2005; Fidalgo et al. J Cell Sci. 123:1274–1284, 2010; Guclu et al. Neurosurgery. 57:1008–1013, 2005; Lant et al. Nat Commun. 6:6449, 2015; Song et al. Dev Cell. 25:507–519, 2013; Ceccarelli et al. J Biol Chem. 286:25056–25064, 2011; Rehain-Bell et al. Curr Biol. 27:860–867, 2017; Xu et al. Structure. 21:1059–1066, 2013; Zhang et al. Front Biosci. 17:2295–2305, 2012; Zhang et al. Dev Cell. 27:215–226, 2013; Zheng et al. J Clin Invest. 120:2795–2804, 2010). TheDrosophilaproteins play a role in the regulation of tube shape in the tracheal (respiratory) system, analogous to the role of the human proteins in the vascular system. To understand the cellular basis for tube dilation defects caused by loss of pathway function, we describe techniques for the generation and analysis of positively marked homozygous mutantGckIIItracheal cells, coupled with an “open book” preparation that can be subjected to immunofluorescent analysis. Dozens of mutant tracheal cells are generated per mosaic animal, and neighboring heterozygous cells in the same animal serve as ideal internal controls.
