根据之前的遗传连锁、表达和小鼠敲除研究,αN-连环蛋白 (CTNNA2) 基因是一种有前途的精神分裂症候选基因。精神分裂症患者吸烟对 CTNNA2 的调节存在差异。在本报告中,描述了灵长类动物特异性 αN-连环蛋白剪接变体(αN-连环蛋白 III)的基因组结构。对精神分裂症患者、非精神病吸烟者和非吸烟者死后海马 αN-连环蛋白 III mRNA 表达的比较显示,与所有其他组相比,非吸烟患者的表达显着下降。该基因最近的进化分歧,以及精神分裂症非吸烟者死后大脑中基因表达的差异,支持了 αN-catenin III 作为一种新型疾病易感基因的作用。
The αN-catenin (CTNNA2) gene represents a promising candidate gene for schizophrenia based upon previous genetic linkage, expression, and mouse knockout studies. CTNNA2 is differentially regulated by smoking in schizophrenic patients. In this report, the genomic structure of a primate-specific αN-catenin splice variant (αN-catenin III) is described. A comparison of αN-catenin III mRNA expression across postmortem hippocampi from schizophrenic and non-mentally ill smokers and non-smokers revealed a significant decrease in expression among patient non-smokers compared to all other groups. The recent evolutionary divergence of this gene, as well as the differences in gene expression in postmortem brain of schizophrenic non-smokers, supports the role of αN-catenin III as a novel disease susceptibility gene.
