Aim: To determine whether the CLDN2 risk allele is associated with CLD or has effects unique to the pancreas. Methods Samples from patients with

CLD (ETOH, NASH, HCV, HBV, PBC, PSC) were prospectively collected and stored in our Liver Disease Biorepository. Patients with CP and healthy control patients were prospectively enrolled in the North American Pancreatitis Study 2 (NAPS2). DNA was purified from blood and genotyped using TaqMan for rs12688220. http://www.selleckchem.com/products/AZD6244.html Comparisons were made utilizing Chi Square and Fisher’s exact test. Results: 412 patients with CLD were compared with 999 patients with CP and 642 healthy control patients. The T allele frequency for all patients with CLD was similar to controls (0.23 vs 0.25, p=0.43) and was significantly less than patients with CP (0.23 vs 0.40, p<0.0001). When only patients with alcoholic liver dis ease (n=76) were analyzed, the T allele frequency was similar to controls (0.24 vs 0.25, p=0.73), and was significantly less than patients with

alcohol-induced CP (n=334) (0.24 vs 0.47, p<0.0001). No differences were seen when males and females were analyzed separately for all patients with CLD and CP. Conclusions: The AZD6738 CLDN2-loci risk allele does not strongly predispose to liver disease. The functional effects of the CLDN2-loci may be unique to the pancreas, especially with chronic alcohol consumption. Disclosures: David C.

Calcium-dependent signaling delivers pro-inflammatory promotes inflammation. Here we aimed to define the role of calcium-dependent signaling in liver macrophages (Mf) Kupffer cells (KC) as it relates to ALD pathogenesis. Methods: We fed alcohol (Lieber-deCarli) or control diet to control, macrophage-depleted (by exposure to clodronate liposomes) or cyclosporine-treated C57Bl6 mice. Kupffer cells (KC) and hepatocytes (Hpt) were isolated by enzymatic digestion and gradient centrifugation. Livers were analyzed by histology, RNA by PCR, protein by western blot, NFAT activity by EMSA, cytokines by ELISA and Multiplex. Results: Alcohol diet, unlike control diet, led to significant increase in serum ALT, suggestive of liver injury and serum cytokines (TNFα, IL1, IL6, KC), suggestive of inflammation, in control C57Bl6 mice.
