Abstract

Ulcerative colitis (UC) and Crohn's disease (CD) are two related yet different forms of chronic intestinal inflammation. We investigated the genes regulated by NKX2-3 in B cells from a UC patient by cDNA microarray and compared the results to those genes regulated by NKX2-3 in B cells from a CD patient. Genes regulated by NKX2-3 in B cells from UC were mainly involved in cell growth, inflammation, and immune response. Among the genes regulated by NKX2-3 in both UC and CD, expression of 145 genes was similarly altered and 34 genes was differentially affected by NKX2-3 knockdown. EGR1 was up-regulated in NKX2-3 knockdown B cells from UC while down-regulated in NKX2-3 knockdown B cells from CD. mRNA expressions of NKX2-3 and EGR1 were increased in diseased intestinal tissues from 19 CD patients. NKX2-3 may play different roles in UC and CD pathogenesis by differential regulation of EGR1.
