Disease duration and age influence CARD15 expression in Crohn’s disease
Journal Title: Advances in Hygiene and Experimental Medicine - Year 2016, Vol 70, Issue
Abstract
One of the susceptibility genes in Crohn’s disease (CD) is CARD15. Our study examined the relationship between peripheral CARD15 expression and phenotype and duration of CD, treatment methods and inflammatory indices. Sixty patients with CD and 30 healthy volunteers as controls were enrolled in the study. Total RNA was isolated from peripheral blood mononuclear cells (PBMCs) with E.Z.N.A. Total RNA Kit (Omega Bio-tek) then quantitative real-time PCR was performed on the ABI Prism 7900 HT Real-Time PCR System. CARD15 gene expression in PBMCs in CD was significantly higher than in the control group. The highest level of gene expression was found in CD patients in the fourth decade of life. The mRNA level of the CARD15 gene was higher in patients with disease duration between 12 and 60 months. A positive correlation was found between erythrocyte sedimentation rate (ESR) and gene expression level. Gene expression increased with increasing level of C-reactive protein and ESR, but it was not statistically significant. CARD15 expression significantly decreased in CD patients treated with anti-TNFα agents compared to azathioprine or steroid treatment groups. Expression of the CARD15 gene in Crohn›s disease is higher than in healthy individuals. Disease duration and age of patients seem to be the most important factors influencing CARD15 expression.
