en Role of Long non Coding RNAs, NEAT1 and Lnc-DC Expression in Pediatric Immune Thrombocytopenic Purpura زیست شناسی ملکولی Molecular Biology مقالات اصلی Original Article <div style="text-align: justify;">Background: Pediatric immune thrombocytopenic purpura (ITP) is an autoimmune disease; whose etiology is unknown. lncRNAs are regulators of numerous actions, which participate in the development of autoimmune diseases. We evaluated the expression ofNEAT1 and Lnc-RNA in dendritic cell (Lnc-DC) in pediatric ITP. Methods: Sixty ITP patients and 60 healthy subjects were enrolled in the present study; Real-time PCR was performed to assess the expression levels of NEAT1 and Lnc-DC in sera of children with ITP as well as healthy children. Results: Both lncRNAs, NEAT1 and Lnc-DC were significantly upregulated in ITP patients in comparison to controls (p <0.0001 and P= 0.001 respectively). Furthermore, significant upregulation of the expression levels of NEAT1 and Lnc-DC were observed in the non-chronic compared with chronic ITP patients. Also, there was significant negative correlation between each of NEAT1 and Lnc-DC and platelet counts before treatment (r= -0.38; P= 0.003 and r= -0.461; P< 0.0001, respectively). Conclusions: serum lncRNAs, NEAT1 and Lnc-DC could be used as potential biomarkers in differentiating childhood ITP patients and healthy controls in addition to differentiating non-chronic from chronic ITP which may provide a theoretical basis for the mechanism and treatment of immune thrombocytopenia.</div> Lnc-DC, NEAT1, Pediatric, ITP. 635 643 http://rbmb.net/browse.php?a_code=A-10-1170-1&slc_lang=en&sid=1 Soha Mohamed Hamdy 100319475328460016821 100319475328460016821 No Departments of Chemistry, Faculty of Science, Fayoum University, Fayoum, Egypt.
