In some adult holometabolous insects, specific epithelial tissues form imaginal discs, small sac-like clusters of cells that form in the larval body. During metamorphosis, in response to hormones, the discs undergo dramatic changes including cell proliferation and differentiation. In Bombyx mori insects, the cuticular protein (CP) genes, which are expressed at prepupal stage in the wing discs, are divided into six groups according to their developmental expression profile and responsiveness to steroid hormones. In this article, we discuss the expression of CP genes in the wing disc, and examine the molecular mechanisms by which metamorphosis and cell transformations are regulated by hormones in insects.
在一些成年完全变态昆虫中,特定的上皮组织形成成虫盘,这是一种在幼虫体中形成的小袋状细胞簇。在变态过程中,细胞增殖和分化等剧烈变化会响应激素而发生在盘上。在家蚕中,表皮蛋白(CP)基因根据其在翅盘上的发育表达谱和对类固醇激素的反应性被分为六组。本文讨论了 CP 基因在翅盘上的表达,并研究了激素调节昆虫变态和细胞转化的分子机制。
