Fig 1: Protein expression levels of tTG and inflammatory proteins in the duodenal tissue of children with CD and the control group. (a) Protein expression of tTG, iNOS, p-NF-?B, and TNF-a were determined by WB analysis and quantified by densitometric analysis. Relative densitometric values of the (b) tTG protein expression; (c) iNOS protein expression; (d) p-NF-?B p65 protein expression; and (e) TNF-a protein expression levels. The ß-actin signal was used to normalize the data, which were then expressed in arbitrary densitometric units. Data were expressed as mean ± SEM (n = 3). * p < 0.05 versus the control group (CD: celiac disease group).
