Results are depicted in Fig. 4A. Absolute Rac1 protein levels in other drug-classified patients groups did not differ from the IBD groups in remission on AZA/MP or TG (p > 0.01), median 0.99 AU in the IFX monotherapy group, median 1.32 AU in the thiopurine/IFX combination group, and median 1.03 AU in the no therapy group, successively. Here, RAC1 is linked to inflammatory bowel disease.
