Abstract

Autism is a severe neurodevelopmental condition with unknown pathobiology. Nevertheless, multiple pieces of evidence suggest long non-coding RNA (lncRNA) dysregulation may be a contributing factor to this disorder. We investigated the association between the expression of five specific lncRNAs and autism. Peripheral blood was collected from 30 children with autism and 41 healthy children. The expression levels of PCAT-29, lincRNA-ROR, LINC-PINT, lincRNA-p21, and PCAT-1 were calculated. Then, their significance as biomarkers was also evaluated. The expression of LincRNA-ROR (27 times), LINC-PINT (5.26 times), LincRNA-p21 (4.54 times), PCAT-29 (16.66 times), and PCAT-1 (25 times) genes was significantly decreased in patients compared to the control group (p values < 0.05). According to the ROC curve analysis for each lncRNA, LincRNA-ROR, LINC-PINT, LincRNA-p21, PCAT-29, and PCAT-1 lncRNAs with diagnostic power of 0.85, 0.67, 0.64, 0.74, and 0.84, respectively, could be used as diagnostic biomarkers for autism. Additionally, significant positive correlations were reported between expression levels of PCAT-1 and PCAT-29 genes. Moreover, a positive correlation was detected between expression levels of lincRNA-ROR and patients’ age. The current study shows further pieces of evidence for deregulation of lncRNAs in autistic patients that show these lncRNAs may play an important part in the pathogenesis of ASD. However, the role of lncRNA in the neurobiology of autism needs to be investigated further.

自闭症患者体内 lncRNAs 的表达评估

自闭症是一种严重的神经发育疾病，其病理生理学尚不清楚。然而，多种证据表明，长非编码 RNA（lncRNA）失调可能是导致这种疾病的一个因素。我们研究了五种特定 lncRNA 的表达与自闭症之间的关系。我们收集了 30 名自闭症儿童和 41 名健康儿童的外周血。计算了 PCAT-29、lincRNA-ROR、LINC-PINT、lincRNA-p21 和 PCAT-1 的表达水平。然后，还评估了它们作为生物标志物的意义。与对照组相比，患者体内 LincRNA-ROR（27 倍）、LINC-PINT（5.26 倍）、LincRNA-p21（4.54 倍）、PCAT-29（16.66 倍）和 PCAT-1 （25 倍）基因的表达量均显著下降（P 值为
