利用芯片克隆技术,我们发现了一个锌指蛋白804a(Zfp804a),它可能是Hoxc8下游的靶基因之一。我们在F9细胞和小鼠胚胎中用芯片聚合酶链式反应证实了Hoxc8与Zfp804a内含子区域的结合。在体外,Hoxc8上调Zfp804a的mRNA水平,增强最小启动子的活性。在E11.5小鼠胚胎中,Zfp804a和Hoxc8共表达。最近的全基因组研究发现Zfp804a(或人类的ZNF804A)是精神分裂症的一个合理的标记,这让我们假设这种胚胎调控也可能在精神病等复杂特征的发育中发挥影响。
Using a ChIP-cloning technique, we identified a Zinc finger protein 804a (Zfp804a) as one of the putative Hoxc8 downstream target genes. We confirmed binding of Hoxc8 to an intronic region of Zfp804a by ChIP-PCR in F9 cells as well as in mouse embryos. Hoxc8 upregulated Zfp804a mRNA levels and augmented minimal promoter activity in vitro. In E11.5 mouse embryos, Zfp804a and Hoxc8 were coexpressed. Recent genome-wide studies identified Zfp804a (or ZNF804A in humans) as a plausible marker for schizophrenia, leading us to hypothesize that this embryogenic regulatory control might also exert influence in development of complex traits such as psychosis.
