  1. 21. Colorectal cancer and radiation response : The role of EGFR, AKT and cancer stem cell markers

    Författare :Sara Häggblad Sahlberg; Bo Stenerlöw; Bengt Glimelius; Marika Nestor; Torgny Stigbrand; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colorectal cancer; radiation; AKT; EGFR; cancer stem cells; CD133; CD44; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap; Biologi med inriktning mot molekylär cellbiologi; Biology with specialization in Molecular Cell Biology;

    Sammanfattning : The primary treatment for colorectal cancer is surgery. Radiotherapy and chemotherapy, sometimes combined, are also frequently used to diminish recurrence risk. In response to radiation exposure, several cellular signaling cascades are activated to repair DNA breaks, prevent apoptosis and to keep the cells proliferating. LÄS MER

  3. 22. The role of hyaluronan and its CD44 receptor in inflammation and cancer

    Författare :Chun-Yu Lin; Jyrki Tenhunen; Miklós Lipcsey; Paraskevi Heldin; Markku Tammi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CD44; Dengue; Hyaluronan; HAS2; iASPP; TGFbeta; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Hyaluronan, an important extra-cellular matrix molecule, was thought to be interstitial connecting glue decades ago. However, recent evidence has revealed that hyaluronan and its binding proteins also play crucial roles in various pathophysiological conditions in humans, including inflammation and infection.

  4. 23. Responses of fibroblasts and chondrosarcoma cells to mechanical and chemical stimuli

    Författare :Juha Piltti; Mikko Lammi; Jukka Häyrinen; Frank Beier; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rho-kinase inhibition; Y-27632; hypoxia; cyclic stretching; human chondrosarcoma 2 8 cells; chondrocyte phenotype; fibroblasts; proteomics; protein pathway analytics; Medical Cell Biology; medicinsk cellbiologi;

    Sammanfattning : Osteoarthritis is an inflammation-related disease that progressively destroys joint cartilage. This disease causes pain and stiffness of the joints, and at advanced stages, limitations to the movement or bending of injured joints. Therefore, it often restricts daily activities and the ability to work. LÄS MER

  5. 24. Free fatty acids and insulin hypersecretion studied in human islets

    Författare :Jing Cen; Peter Bergsten; Miriam Cnop; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; free fatty acids; palmitate; human islets; EndoC-βH1 cells; metformin; sorcin; insulin secretion; mitochondrial respiration; ER stress; human transcriptome array; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Free fatty acid (FFA) levels are increased in many obese subjects. High FFA levels stimulate the pancreatic beta-cells but have negative long-term effects. In obese children with high FFA levels circulating insulin concentration is high early in life but decline with age precipitating the development of type 2 diabetes mellitus (T2DM). LÄS MER

  7. 25. Effects of Free Fatty Acids on Insulin and Glucagon Secretion : – with special emphasis on the role of Free fatty acid receptor 1

    Författare :Hjalti Kristinsson; Peter Professor; Birgitte Holst; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FFAR1; GPR40; palmitate; lipotoxicity; islets of Langerhans; type 2 diabetes; obesity; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Prevalence of type 2 diabetes mellitus (T2DM) is still rising and even so in the juvenile population. Obesity is highly associated with increased risk for developing T2DM. LÄS MER
