概括

研究人员确定了45个影响神经前体细胞发育的先天性心脏病 (CHD) 基因,这表明它们可能会增加自闭症谱系障碍 (ASD) 风险. 细胞生物学成为这种共同共患病的关键因素.

科学领域:

发育生物学发展生物学
遗传学是一个遗传学.
神经科学是一个神经科学.
心脏病学心脏病学

背景情况:

自闭症谱系障碍 (ASD) 经常与先天性心脏病 (CHD) 发生,但潜在的分子机制尚不清楚.
识别与ASD风险相关的CHD变异可能使得早期诊断和干预受影响的儿童.
已知的ASD和CHD基因之间存在有限的重叠,需要新的策略来优先考虑ASD风险的CHD基因.

研究的目的:

为了确定破坏神经前体细胞 (NPC) 生物学的先天性心脏病 (CHD) 基因,假设这些基因更有可能产生自闭症谱系障碍 (ASD) 的风险.
探索阴在ASD和CHD的共同生物学中的作用.
验证特定的CHD基因作为ASD的潜在风险因素.

主要方法:

进行了体外聚合的CRISPR干扰 (CRISPRi) 选,以评估CHD基因对神经原生细胞 (NPC) 增殖和生存的影响.
分析了ASD和CHD基因之间的物理相互作用,以确定为特定生物功能丰富的集群.
研究了七个候选基因 (CEP290,CHD4,KMT2E,NSD1,OFD1,RFX3,TAOK1) 对乳毛形成和心脏发育的体外和体内影响.

主要成果:

确定了45个CHD基因,这些基因显著影响NPC增殖和/或生存.
发现了一组与ASD和CHD相互作用的基因集群,这些基因对状生物学的丰富.
观察到七个候选基因的干扰在体外影响初级乳毛形成;体内研究证实了TAOK1在运动乳毛和心脏发育中的作用.

结论:

影响NPC生物学的CHD基因的一个子集可能会给ASD带来风险,突出显示神经发生是潜在的联系.
乳在ASD和CHD的共同病因学中发挥着重要作用.
结果确定了特定的CHD基因是潜在的ASD风险贡献者,需要进一步调查.

Mechanism of Ciliary Motion

Mechanism of Ciliary Motion

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Microtubules in Signaling

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Autism Spectrum Disorder

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
