JUP and atherosclerosis: Intravenous injection of Pg to the bloodstream alone induced atherosclerotic changes and significantly increased systemic and local aortic expressions of inflammatory factors, NF-κB p65, phospho-p38-MAPK, and JNK, especially in Group D. Injection of microamount Pg induced inflammatory immune response and accelerated atherosclerosis, in which the NF-κB p65, p38-MAPK, and JNK signaling pathways played important roles.
