  2. 1. Morphological Features and Mismatch Repair in Colorectal Tumors

    Author : Britta Halvarsson; Tumörmikromiljö; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patologi allmän ; patologisk anatomi; Lynch syndrome; Colorectal tumors; HNPCC; Mismatch repaire; pathological anatomy; General pathology; Genetik; cytogenetik; cytogenetics; Genetics; Medicin människa och djur ; Medicine human and vertebrates ; Immunohistochemistry;

    Abstract : Corlorectal cancer affects 5% of individuals in the Western world and heredity is estimated to cause at least 10% of the tumors. Defective mismatch repair (MMR) is a tumorigenic mechanism through which about 15% of colorectal cancer develops and this feature characterizes tumors associated with Hereditary Nonpolyposis Colorectal Cancer (HNPCC) or Lynch syndrome.

  4. 2. Tumors associated with Hereditary Nonpolyposis Colorectal Cancer: Defective Mismatch Repair and Familial Risk of Cancer

    Author : Kajsa Ericson Lindquist; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; cancerology; Cytologi; onkologi; cancer; Multiple Tumors; Hereditary Nonpolyposis Colorectal Cancer; Cytology; Cohort study; Population based; Familial Risk of Cancer; Immunohistochemistry; MSH2; MSH6; MLH1; Microsatellite Instability; Soft Tissue Sarcomas; Cancer of the Upper Urinary Tract; Cancer of the Small Intestine; Colorectal Cancer;

    Abstract : Inactivation of the DNA mismatch repair (MMR) system is a tumorigenic mechanism involved in 15-20% of tumor types such as colorectal and endometrial cancer and is specifically associated with the Hereditary Nonpolyposis Colorectal Cancer (HNPCC) syndrome. These MMR defective tumors are characterized by microsatellite instability (MSI), a phenomenon that reflects alterations in length of repeated sequences, and 90% of MSI tumors show loss of immunohistochemical expression for the MMR protein affected.

  5. 3. Prostanoids and colorectal cancer

    Author : Annika Gustafsson Asting; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer prostanoid receptors cyclooxygenase PGE2 transcription factors;

    Abstract : Tumor disease is a main cause of death in Western countries and a most common malignancy is colorectal cancer (CRC). Growing tumors are dependent on interactions among several different cells as well as signaling pathways. READ MORE

  6. 4. Targeting allelic loss in colorectal cancer

    Author : Verónica Rendo; Tobias Sjöblom; Nickolas Papadopoulos; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer; gene editing; loss of heterozygosity; targeted therapy; whole genome sequencing;

    Abstract : Targeted cancer therapy exploits molecular differences between tumor and normal cells to selectively kill cancer cells. Whereas targeting of activated oncogenes has proved clinically useful, few current therapies exploit loss-of-function mutations in tumor suppressor genes or in the genome at large. READ MORE

  7. 5. p73 in colorectal cancer

    Author : Daniella Pfeifer; Sun Xiao-Feng; Vladimir Bykov; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Colorectal cancer (CRC) is the third most common cancer in the world, with about 5000 new cases in Sweden every year. CRC is caused by mutation (inherited or acquired) in genes, by gene variants and changed expression of proteins. The primary way to achieve a curative result for CRC is to remove the tumor by surgery. READ MORE
