Aberrant Expression of Long Non-coding RNAs in Peripheral Blood of Autistic Patients

Long non-coding RNAs (lncRNAs) constitute a large proportion of human transcriptome and are involved in fundamental aspects of neurodevelopment. In the present study, we evaluated expression levels of three lncRNAs, namely, Nuclear Paraspeckle Assembly Transcript 1 (NEAT1), p21-associated ncRNA DNA damage–activated (PANDA), and taurine-upregulated gene 1 (TUG1), in peripheral blood of autism spectrum disorder (ASD) patients compared with those in healthy subjects. We found a significant upregulation of NEAT1 and TUG1 in ASD patients. In addition, relative expressions of the pairs of lncRNAs were significantly correlated in both patients and healthy subjects. However, expressions of these lncRNAs were not correlated with age of study participants. The present study provides further evidences for dysregulation of lncRNAs in ASD patients.
