印戒细胞癌(SRCC)是胃癌的一种独特亚型,其细胞间粘附受损。其发病机制尚不清楚。在这里,我们表明,表达驱动蛋白相关蛋白3(KAP 3),货物接头亚基的驱动蛋白超家族蛋白3(KIF 3),马达蛋白,是特别减少SRCC的胃。CRISPR/Cas9介导的基因敲除实验表明,KAP 3的缺失通过使RhoA失活而损害了周向肌动球蛋白电缆的形成,导致细胞-细胞粘附减弱。此外,在KAP 3基因敲除细胞中,层粘连蛋白(基底膜的关键成分)的高尔基体后转运受到抑制,导致基底膜形成受损。总之,这些发现揭示了KAP 3在胃SRCC发病机制中的潜在作用。
Signet-ring cell carcinoma (SRCC) is a unique subtype of gastric cancer that is impaired for cell–cell adhesion. The pathogenesis of SRCC remains unclear. Here, we show that expression of kinesin-associated protein 3 (KAP3), a cargo adaptor subunit of the kinesin superfamily protein 3 (KIF3), a motor protein, is specifically decreased in SRCC of the stomach. CRISPR/Cas9-mediated gene knockout experiments indicated that loss of KAP3 impairs the formation of circumferential actomyosin cables by inactivating RhoA, leading to the weakening of cell–cell adhesion. Furthermore, in KAP3 knockout cells, post-Golgi transport of laminin, a key component of the basement membrane, was inhibited, resulting in impaired basement membrane formation. Together, these findings uncover a potential role for KAP3 in the pathogenesis of SRCC of the stomach.
