Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease which is associated with inflammatory bowel disease (IBD) in most cases. As there is currently no medical therapy which alters the natural history of PSC, liver transplantation may be required. Areas covered: We searched for articles in PubMed and critically reviewed current literature on the interrelationship between PSC and IBD with a specific focus on considerations for patients in the liver transplant setting. Expert commentary: PSC is an uncommon disease which limits available studies to be either retrospective or contain relatively small numbers of patients. Based on observations from these studies, the behavior and complications of PSC and IBD impact on each other both before and after a liver transplant. Both these autoimmune conditions and their associated cancer risk also influence patient selection for transplantation and may be impacted by immunosuppression use post-transplant. Hence, a complex interplay exists between PSC, IBD and liver transplantation which requires clarification with ongoing research.

Abstract
To elucidate the roles of human gallbladder mucin (HGBM), such as in gallstone formation and cytoprotection, it is essential to identify HGBM and study its expression. This was performed by metabolic labeling, Western blotting, immunohistochemistry, and RT-PCR. In a large number of individuals, antibodies against purified HGBM and against MUC5B detected a mucin precursor (approximately 470 kDa) in the gallbladder and colon, but not in the small intestine. In the gallbladder, Western blotting using specific anti-MUC5B antibodies showed that this mucin precursor represented an identical mucin, MUC5B. RT-PCR experiments demonstrated a similar tissue distribution pattern of MUC5B mRNA. Immunohistochemistry with anti-HGBM and anti-MUC5B showed staining in gallbladder epithelial cells and colonic goblet cells in the crypt base, but not in the small intestine; double labeling showed that HGBM was located in small granules within goblet cells, colocalizing to MUC2-containing goblet cells. Metabolic labeling demonstrated the secretion of mature MUC5B in the colon. Conclusively, MUC5B is identified as the prominent HGBM and is also expressed and secreted in the colon.
