Figure 2 Immunohistochemical detection of OGR1. ( A , B ) OGR1 (GPR68) recombinant rabbit monoclonal antibody (16H23L16) for immunohistochemical (IHC) detection of OGR1 was verified in previously validated tools. Caco-2 clone stably overexpressing OGR1 (clone U1); negative control, Caco-2 vector control (VC) cells. ( A1 , A2 ) Strong positive OGR1 staining (brown colour), predominantly in the cytoplasm, is present in OGR1-clone U1. ( B1 , B2 ) No specific staining for OGR1 in VC cells. Counterstaining with haematoxylin. Scale bar: ( A1 , B1 ) 100 um and ( A2 , B2 ) 25 um. ( C ) Localisation of OGR1 in healthy human duodenal mucosa. Scale bars: C. Insert overview image 1 mm; detail images, ( C1 ) 250 um; ( C2 ) 100 um; ( C3 , C5 ) 50 um; ( C4 , C6 ) 25 um. ( D ) Localisation of OGR1 in duodenal tunica muscularis. Scale bars: ( D1 , D2 ) 1 mm; detail images, ( D3 , D4 ) 25 um. OGR1: ovarian cancer G-protein-coupled receptor 1.

Experimental details

Figure 3 OGR1 protein expression is significantly increased in the inflamed mucosa of IBD patients. Immunohistochemical detection of OGR1 using the anti-OGR1 antibody 16H23L16. Paired samples: ( A1 - A3 , B1 - B3 ) non-inflamed; ( A4 - A6 , B4 - B6 ) inflamed. Representative images shown are from two CD patients. Scale bars: ( A2 , B2 ) and ( A5 , B5 ) detail images, 100 um; ( A3 , B3 ) and ( A6 , B6 ) 25 um. ( C , D ) Representative images shown are from two non-IBD subjects. Scale bars: ( C1 , D1 ) 100 um; ( C2 , D2 ) detail images, 25 um. Intestinal resections were taken from five non-IBD subjects and paired (non-inflamed and inflamed) samples from five CD patients and five UC patients. ( E ) Total protein was isolated from colonic tissue samples and Western blotting was performed using an OGR1 (GPR68) custom mouse monoclonal antibody (AbMart). ( F ) Densitometry after normalization of OGR1 to beta-actin: five non-IBD subjects, four CD patients and four UC patients. Statistical analysis was performed using one-way ANOVA followed by Tukey's post-test (** p < 0.01; *** p < 0.001). CD: Crohn's disease; IBD: inflammatory bowel disease; OGR1: ovarian cancer G-protein-coupled receptor 1; UC: ulcerative colitis.
