Studies utilizing knockout and transgenic mouse models revealed an important role for connexin 43 (Cx43) gap junctions in cardiac development. This may involve a quantitative requirement for gap junctions in modulating the development of cardiac crest cells. In addition, studies in humans and Xenopus indicate that Cx43 gap junctions also may play a role in regulating heart laterality. Together, these findings indicate that the perturbation of Cx43 function could play a significant role in specific congenital heart malformations.
利用基因敲除和转基因小鼠模型进行的研究揭示了连接蛋白43(Cx43)间隙连接在心脏发育中的重要作用。这可能涉及间隙连接在调节心脏嵴细胞发育方面的定量需求。此外,对人类和非洲爪蟾的研究表明,Cx43间隙连接也可能在调节心脏左右不对称性中发挥作用。这些发现共同表明,Cx43功能的扰动可能在特定先天性心脏畸形中起重要作用。
