精神分裂症中的DISC1基因是包括精神分裂症和抑郁症在内的重大精神疾病的遗传易感基因。最近发现DISC1蛋白与Wnt信号蛋白DIX结构域相互作用,该结构域包含1(Dixdc1)。这两种蛋白都依赖于Wnt信号参与神经前体细胞的增殖,而不依赖于Wnt信号参与神经迁移。有趣的是,它们对神经前体细胞增殖的影响是相加的。与DISC1类似,Dixdc1的突变可能会导致小鼠的异常行为,并导致人类的精神分裂症或抑郁症。为了进一步探索这一假设,我们在Dixdc1基因座产生了突变的小鼠,并分析了它们的行为。Dixdc1−/−小鼠脉冲前抑制正常,但自发活动减少,在高架+迷宫中表现出异常行为,惊吓反应能力下降。我们的结果表明,Dixdc1−/−小鼠将是阐明DISC1在主要精神疾病中的分子病理生理学的有用工具。
Disrupted-in-Schizophrenia-1 (DISC1) is a genetic susceptibility locus for major mental illness, including schizophrenia and depression. The Disc1 protein was recently shown to interact with the Wnt signaling protein, DIX domain containing 1 (Dixdc1). Both proteins participate in neural progenitor proliferation dependent on Wnt signaling, and in neural migration independently of Wnt signaling. Interestingly, their effect on neural progenitor proliferation is additive. By analogy to Disc1, mutations in Dixdc1 may lead to abnormal behavior in mice, and to schizophrenia or depression in humans. To explore this hypothesis further, we generated mice mutant at the Dixdc1 locus and analyzed their behavior. Dixdc1−/− mice had normal prepulse inhibition, but displayed decreased spontaneous locomotor activity, abnormal behavior in the elevated plus maze and deficits in startle reactivity. Our results suggest that Dixdc1−/− mice will be a useful tool to elucidate molecular pathophysiology involving Disc1 in major mental illnesses.
