概括

这项研究发现,自闭症儿童的五种长非编码RNAs (lncRNAs) 的表达减少,这表明它们有可能成为自闭症谱系障碍 (ASD) 的诊断生物标志物. 需要进一步的研究来了解它们在ASD神经生物学中的作用.

科学领域:

神经科学是一个神经科学.
遗传学是一个遗传学.
生物标志物发现发现

背景情况:

自闭症谱系障碍 (ASD) 是一种复杂的神经发育状况,其病理生物学在很大程度上是未知的.
新出现的证据表明,长非编码RNAs (lncRNAs) 的失调可能会导致ASD的发病.
这项研究的重点是研究特定的lncRNAs作为ASD的潜在参与者.

研究的目的:

研究五种特定lncRNAs (PCAT-29,lincRNA-ROR,LINC-PINT,lincRNA-p21,PCAT-1) 的表达水平与自闭症之间的关联.
评估这些lncRNAs作为自闭症生物标志物的诊断潜力.
探索这些lncRNAs表达与年龄等临床因素之间的相关性.

主要方法:

从30名被诊断为自闭症的儿童和41名健康对照组中采集了外周血液样本.
进行了定量分析,以测量PCAT-29,lincRNA-ROR,LINC-PINT,lincRNA-p21和PCAT-1的表达水平.
采用接收器操作特征 (ROC) 曲线分析来评估每个lncRNA的诊断能力.

主要成果:

与对照组相比,所有五种研究的lncRNAs (LincRNA-ROR,LINC-PINT,LincRNA-p21,PCAT-29和PCAT-1) 在患有自闭症的儿童中都显示出显著下降的表达 (p <0.05).
在ROC曲线分析中,LincRNA-ROR (0.85) 和PCAT-1 (0.84) 的诊断能力很好,PCAT-29 (0.74),LINC-PINT (0.67) 和LincRNA-p21 (0.64) 的诊断能力中等.
在PCAT-1和PCAT-29表达之间,以及在lincRNA-ROR表达和患者年龄之间观察到显著的正相关性.

结论:

这些发现为患有自闭症的个体中特定 lncRNAs 的放松调节提供了进一步的证据.
这些lncRNAs显示出作为自闭症谱系障碍诊断生物标志物的潜力.
需要进一步研究lncRNAs在ASD神经生物学和发病过程中的确切作用.

关键词:

在LINC-PINT上,我们可以看到.这就是LincRNA-ROR.这就是LincRNA-p21的原因.在PCAT-1中使用PCAT-1.在PCAT-29中使用PCAT-29.自闭症自闭症自闭症生物标志物生物标志物

lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

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.
