LRPAP1 and atherosclerosis: In addition to the KIAA0513-Abs employed in the present study, autoantibodies against ATPase, Ca++ transporting, plasma membrane 4, bone morphogenetic protein 1, deoxyhypusine synthase, low-density lipoprotein receptor-related protein-associated protein 1 and additional sex combs-like 2, which are markers of atherosclerosis, were also elevated in the sera of patients with EC (13,14,17,18), indicating that arterial abnormalities can also affect the carcinogenic process.
