自闭症谱系障碍(ASD)是一种神经发育疾病,以智力障碍(ID)和注意力缺陷/多动障碍(ADHD)为常见合并症。最近的遗传和临床研究报告称,KDM6B(一种编码组蛋白 H3 赖氨酸 27 特异性去甲基酶的基因)是 ASD 风险最高的基因之一。然而,KDM6B突变与神经发育疾病之间的关系仍不清楚。在这里,我们使用动物模型来证明小鼠中一个 Kdm6b 等位基因的基因缺失会导致类似自闭症的社交能力和物体识别记忆受损。此外,突变小鼠的运动活性和冲动性显着增加,这两种类似多动症的行为特征可以通过哌醋甲酯治疗得到改善。因此,我们的研究不仅揭示了破坏性 KDM6B 突变与 ASD/ADHD 样行为缺陷之间的潜在因果关系,而且还为研究 Kdm6b 突变相关神经发育疾病的细胞和分子机制提供了一种新的小鼠模型。
Autism spectrum disorder (ASD) is a neurodevelopmental disease that has intellectual disability (ID) and attention-deficit/hyperactivity disorder (ADHD) as its common comorbidities. Recent genetic and clinical studies report that KDM6B, a gene encoding a histone H3 lysine 27-specific demethylase, is one of the highest ASD risk genes. However, the relationship between KDM6B mutations and neurodevelopmental diseases remains unclear. Here we use an animal model to show that genetic deletion of one Kdm6b allele in mice leads to autistic-like impaired sociability and object recognition memory. In addition, the mutant mice display markedly increased locomotor activity and impulsivity, two ADHD-like behavioral traits that are ameliorated by methylphenidate treatment. Thus, our study not only uncovers a potential causal link between disruptive KDM6B mutations and ASD/ADHD-like behavioral deficits but also provides a new mouse model for studying the cellular and molecular mechanisms underlying the Kdm6b-mutation-related neurodevelopmental diseases.
