Chemoimmunotherapy with antibody-drug conjugates (ADC) is emerging as a promising therapy for solid tumors, whereas radioimmunotherapy (RAIT) of solid tumors has been relatively ineffective because of their resistance to radiation. We developed antibody-SN-38 conjugates that have significant antitumor activity in xenograft models at nontoxic doses. The goal of this study was to determine if an ADC could be combined with RAIT to enhance efficacy without a commensurate increase in host toxicity. Nude mice bearing human pancreatic cancer xenografts (Capan-1 and BxPC-3) were treated with a single dose of 90Y-labeled antimucin antibody (hPAM4; clivatuzumab tetraxetan) alone or in combination with an anti-Trop-2-SN-38 conjugate, typically administered twice weekly over 4 weeks...

BACKGROUND: The ingestion of both ethanol and whisky can induce acute gastrointestinal bleeding. The effects of the congeners, substances other than ethanol in whisky, on the ethanol-induced gastric mucosal damage were examined in the rat model. METHODS: After the whisky congeners were intragastrically administered previous to or simultaneous with ethanol ingestion, the gastric damage was macroscopically and microscopically measured. RESULTS: The simultaneous administration of the whisky congeners at a dose of 5 mg/kg body weight, which corresponds to the concentration of congeners contained in whisky, with 50% ethanol did not inhibit the hemorrhagic lesions, but inhibited them at a dose of 150 mg/kg...

Intraductal papillary-mucinous tumor of the pancreas is occasionally accompanied by biliopancreatic fistula. However, it is difficult to show the inflow of mucin produced by the tumor into the common bile duct. To confirm the biliopancreatic fistula, the mucin-rich fraction was purified from the bile and stained with antimucin antibodies. Western blot analysis showed characteristic smear staining patterns for mucin molecules with three types of antimucin antibodies. Immunohistochemical analysis with the antibody showed significant signals of the cancer cells and the luminal content of the dilated pancreatic duct...

OBJECTIVE: Airway mucins may play an important role in the mechanism of respiratory complications after cardiopulmonary bypass in infants and children. Our aim was to measure airway mucin levels before and after cardiopulmonary bypass and to determine whether changes in mucin levels were associated with the development of respiratory complications. METHODS: Airway glycoprotein and mucins (MUC5AC, MUC5B, and MUC2) in serial small-volume airway lavage samples from 39 young children who underwent cardiac operations with cardiopulmonary bypass were measured by slot-blot assay with specific antimucin peptide antibodies...

Cystic fibrosis (CF) patients develop chronic lung infections associated with airway obstruction by viscous and insoluble mucus secretions. Although mucus glycoproteins (mucins) are thought to be responsible for mucus plugs, other glycoconjugate components of airway secretions have not been systematically evaluated. The aim of the present study was to determine whether chondroitin sulfate proteoglycans (CSPG) contribute to the insolubility of CF sputum. Sputa obtained from 18 CF patients were incubated with chondroitinase ABC (ChABC) or buffer (control) for 18 h at 37 degrees C, and after centrifugation at 12,000 g, the volume of the insoluble pellet and turbidity of the supernatant were determined as measures of solubility...

The incidence of esophageal tumors, and of adenocarcinoma in particular, has risen markedly in recent years in the developed countries. The use of a variety of histopathological and biological markers is now offering promising prospects for the future. Vertical tumor invasion, intratumoral microvessel density, antimucin monoclonal antibodies, flow cytometry, telomerase activity, and overexpression of cyclin D1 have been correlated with the staging and prognosis of esophageal carcinomas. By combining these markers with Lugol staining, a practical new method of staging esophageal tumors may become available in the coming years...

BACKGROUND: Adenoma malignum of the uterine cervix was first described by Gusserow. We report here a case with cytologic, histologic and colposcopic findings and immunohistochemistry for HIK-1083. CASE: A 42-year-old female was noted to have a probable adenoma malignum due to the detection of atypical cells classified as V. On colposcopy, comma-shaped, atypical vessels spread over the entire cervical area. Histologic findings were characteristic of tumor invasion beyond the layer of cervical glandular ducts...

We have developed an air-liquid interface culture system for human nasal epithelial cells that differentiate into mucociliary phenotypes in a defined serum-free medium. Dissociated cells obtained from nasal polyps were cultured on a collagen gel substrate. At confluence, the cells lost characteristics of differentiated cells, and secretory cell and ciliated cell differentiation appeared after 7 days in an air-liquid interface. After 21 days, about half of the epithelial cells were stained with Alcian blue-periodic acid-Schiff stain or monoclonal antibody HCS18, which was directed against human nasal mucin specific for epithelial secretory (goblet) cells...

To clarify the role of colonic mucin in the autoimmune process of ulcerative colitis, circulating antibodies against human colonic mucin were investigated. Purified colonic mucin, obtained from human colonic mucosa by gel filtration, using a Bio-Gel A-1.5-m column and CsCl equilibrium density gradient, was divided into soluble mucin (S-mucin) secreted extracellularly and membranous mucin (M-mucin) binding to cell membrane. Sodium dodecylsulfate polyacrylamide gel electrophoresis and Western blotting analysis showed that antibodies in the serum samples of some patients with ulcerative colitis recognized purified S- and M-mucin of >180-kD...

BACKGROUND/PURPOSE: Mucin glycoproteins (mucins) recently have been shown to be deficient in the colonic mucosa of patients with Hirschsprung's disease (HD). The authors performed a detailed histo- and immunohistochemical analysis of mucins in the colonic mucosa and studied the expression of mucin genes to characterize histologically mucin quality and gene expression in HD compared with controls. METHODS: Paraffin-embedded 4-microm thick sections from patients with HD (n = 11 ganglionic, 10 aganglionic) and controls (n = 19) were taken...

CAM 17.1 is an antimucin monoclonal antibody which has recently been proven valuable as a reagent for serological diagnosis of pancreatic cancer. A series of studies have been performed to characterise its epitope. First it was screened immunohistochemically against a wide range of formalin-fixed normal and neoplastic human tissues and showed widespread binding to mucin throughout the gastro-intestinal tract, in both normal and malignant tissues. In pancreas, strong intracellular staining of acinar and ductal cells was found in normal tissue and in carcinoma cells in tumours...

Sixteen research groups participated in the ISOBM TD-4 Workshop in which the reactivity and specificity of 56 monoclonal antibodies against the MUC1 mucin was investigated using a diverse panel of target antigens and MUC1 mucin-related synthetic peptides and glycopeptides. The majority of antibodies (34/56) defined epitopes located within the 20-amino acid tandem repeat sequence of the MUC1 mucin protein core. Of the remaining 22 antibodies, there was evidence for the involvement of carbohydrate residues in the epitopes for 16 antibodies...
