LncRNA DQ786243 Affects Treg Related CREB and Foxp3 Expression in Crohn's Disease
Overview
Affiliations
Background: Long non-coding RNAs (lncRNAs) have different functions in cells. They work as signals, decoys, guides, and scaffolds. Altered lncRNA levels can affect the expression of gene products. There are seldom studies on the role of lncRNAs in inflammatory bowel disease (IBD).
Results: Quantitative RT-PCR showed that DQ786243 was significantly overexpressed in clinical active CD patients compared with clinical inactive CD patients (P = 0.0118) or healthy controls (P = 0.002). CREB was also more highly expressed in active CD than in inactive CD (P = 0.0034) or controls (P = 0.0241). Foxp3 was interestingly lower in inactive CD than in active CD (P = 0.0317) or controls (P = 0.0103), but there were no apparent differences between active CD and controls. CRP was well correlated with DQ786243 (r = 0.489, P = 0.034), CREB (r = 0.500, P = 0.029) and Foxp3 (r = 0.546, P = 0.016). At 48 hours after DQ786243 transfection, qRT-PCR showed both CREB (P = 0.017) and Foxp3 (P = 0.046) had an increased mRNA expression in Jurkat cells. Western blot showed the same pattern. After DQ786243 transfection, CREB phosphorylation ratio (p-CREB/t-CREB) was increased (P = 0.0043).
Conclusion: DQ786243 can be related with severity of CD. It can affect the expression of CREB and Foxp3 through which regulates the function of Treg. CREB itself seems not the mediator of DQ786243 to up-regulate Foxp3. The phosphorylation of CREB might play a more important role in the process.
