  2. 1. 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

  4. 2. Human Embryonic Stem Cells: Directed Differentiation into Posterior Foregut Endoderm and a Functional Assay for Definitive Endoderm

    Author : Martina Johannesson; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : A decade has passed since the first human embryonic stem cell (hESC) line was established, providing immense hope in curing diseases by cell replacement therapy. For instance, in the pancreas, the insulin-producing β-cells are damaged in diabetes patients, and a successful replacement of those cells could provide a cure. READ MORE

  5. 3. FGF signaling in specification of hESC-derived definitive endoderm

    Author : Jacqueline Ameri; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Diabetes affects around 200 million people worldwide. Curing diabetes would require the prevention of autoimmune destruction of beta cells and restoration of the beta cell mass restored either through regeneration or transplantation of the insulin producing cells. READ MORE

  6. 4. Rotavirus Disease Mechanisms Diarrhea, Vomiting and Inflammation : How and Why

    Author : Marie Hagbom; Lennart Svensson; Karl-Eric Mangusson; Ove Lundgren; Niklas Arnberg; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Rotavirus infections cause diarrhea and vomiting that can lead to severe dehydration. Despite extensive tissue damage and cell death, the inflammatory response is very limited. READ MORE

  7. 5. Deciphering cell motility and spatial sensing of intestinal cell types using an ex vivo intestinal model

    Author : Anna Webb; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The intestine is a highly organized tissue with two distinct regions: the crypt and the villus. When stem cells divide at the crypt bottom, half of their progeny migrates upwards towards the villus, where they differentiate into various cell types, including the abundant absorptive enterocytes.
