  2. 1. New Approaches to Studies of Paracellular Drug Transport in Intestinal Epithelial Cell Monolayers

    Author : Staffan Tavelin; Per Artursson; Staffan Tavelin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; intestinal epithelium; tight junctions; cell culture; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Studies of intestinal drug permeability have traditionally been performed in the colon-derived Caco-2 cell model. However, the permeability of these cell monolayers resembles that of the colon rather than that of the small intestine, which is the major site of drug absorption following oral administration.

  4. 2. Human intestinal T lymphocytes : a comparative analysis of phenotype and function in normal and inflamed mucosa

    Author : Silvia Melgar; Nadine Cerf-Bensussan; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestinal mucosa; intraepithelial lymphocyte; lamina propria lymphocyte; γδ T cell; regulatory T cell; cytotoxicity; cytokine; basal lymphoid aggregate; ulcerative colitis; Crohn s disease;

    Abstract : The epithelial lining of the gut must allow immediate contact with beneficial components as nutrients and normal microflora. At the same time it runs the constant risk of attack from pathogenic microbes and noxious agents. READ MORE

  5. 3. Involvement of Eicosanoid Signaling in Intestinal Epithelial Cell Survival

    Author : John Öhd; Malmö Experimentell patologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General pathology; Tcf Lef; Bcl-2 family; b-catenin; 5-LO; apoptosis; cell survival; colorectal cancer; COX-2; LTD4; CysLT1 R; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Abstract : Eicosanoids are known to be involved in many different aspects of eukaryotic physiology and pathology. Notably, over the past 10 years much attention has been given to cyclooxygenase-2 (COX-2) due to its involvement in colorectal cancer. Less is known about the other major branch of arachidonic acid metabolism, namely the lipoxygenases (LO). READ MORE

  6. 4. O-glycosylation of intestinal and respiratory mucins in health and disease

    Author : Jessica Holmén Larsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucins; oligosaccharide; O-linked glycosylation; mass spectrometry; MUC2; Fut2 enzyme; Nippostrongylus brasiliensis infection; Cystic Fibrosis; Ulcerative colitis;

    Abstract : Mucins are large glycoproteins with a diverse O-glycosylation constituting up to 80% of the total mucin mass. The mucus layer covering the epithelial cells of the gastrointestinal and respiratory tract is largely made up of gel-forming mucins. READ MORE

  7. 5. Molecular understanding of KRAS- and BRAF-mutated colorectal cancers

    Author : Ida Lundberg; Richard Palmqvist; Maria Wikberg; Sofia Edin; Anita Sjölander; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; BRAF; KRAS; SOX2; CDX2; cancer stem cell; Th1 lymphocytes; miRNA; prognosis;

    Abstract : Colorectal cancer (CRC) is the third most commonly diagnosed malignancy in both men and women, and one of the leading causes of cancer-related deaths worldwide. One frequently mutated pathway involved in oncogenesis in CRC is the RAS/RAF/MAP kinase pathway. READ MORE
