OLFM4 and inflammatory bowel disease: This analysis revealed OLFM4 upregulation in inflamed biopsies of UC patients compared to paired biopsies from uninflamed regions (Figure 7Eii) from a genome-wide expression study comparing biopsies from 67 patients with UC and 31 control subjects (23 normal and 8 patients with inflamed non-IBD biopsies) (GEO accession GSE11223; Noble et al., 2008).
