Human mucin genes include membrane-bound mucins (MUC1, MUC3, MUC4) and secretory mucins (MUC2, MUC5AC, MUC5B, MUC6). Our aim was to determine mucin gene expression in human gallbladder cell lines, normal gallbladder from liver donors (N = 7) and surgical specimens with mild chronic cholecystitis (N = 29), chronic cholecystitis (N = 48), and acute and chronic cholecystitis (N = 27). MUC1 mRNA was ubiquitous; however, only rare MUC1 immunoreactivity was detected. MUC3, MUC5AC, MUC5B, and MUC6 mRNA were present in all gallbladder specimens and cell lines examined. Prominent MUC3, MUC5AC, MUC5B, and MUC6 immunoreactivity was present in 86-100% of normal gallbladders. The frequency of MUC5AC reactivity was decreased in specimens with acute cholecystitis (P < 0.05). In contrast, MUC2-reactivity was absent in normal gallbladder and present in 53.8% of acute cholecystitis specimens (P < 0.05). Surface epithelium is characterized by MUC3, MUC5AC, and MUC5B, whereas deeper mucosal folds display MUC5B and MUC6 immunoreactivity. Gallbladder epithelium demonstrates a unique and diverse pattern of mucin core proteins that becomes altered with increasing degrees of inflammation.

Tangier disease is a rare, autosomally inherited disorder of lipoprotein metabolism characterized by absence or marked deficiency of normal high density lipoprotein (HDL) cholesterol in plasma resulting in the accumulation of cholesterol esters in various organs. A 57-year old male with a past medical history of hypertension, coronary artery disease and splenectomy admitted to our hospital for rectal bleeding. In routine laboratory tests thrombocytopenia, hypocholesterolemia and low HDL levels were detected. Colonoscopy revealed 1-3 mm sized, brownish, spotty lesions spread throughout the colonic mucosa. Histopathologically accumulation of foam cells which showed lipid vacuoles and myeline figures on electron microscopy were observed. Bone marrow biopsy was also suggestive of lipid storage disease. The laparoscopic operation performed for acute cholecystitis showed similar appearances in the gall bladder and liver. The case was diagnosed as rare presentation of Tangier disease with gallbladder involvement in view of the low HDL cholesterol level and systemic lipid deposition.
