To further figure out BBR’s molecular mechanism in colitis cure, transfection of the miR-103a-3p inhibitor and BRD4 elevation vector and their separate NC was into Caco-2 cells stimulated via IL-6, and co-culture was with BBR with verification of the transfection efficiency (Figures 6a,b, Attached Figures. The gene discussed is BRD4; the disease is colitis.
