1. 16. Genetic and epidemiological studies of hereditary colorectal cancer

   Författare :Kristina Cederquist; Henrik Grönberg; Irina Golovleva; Gösta Holmgren; Mef Nilbert; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Lynch syndrome; HNPCC; colorectal cancer; endometrial cancer; cancer risk; MSI; MLH1; MSH2; MSH6; genome-wide scan; Genetik; Clinical genetics; Klinisk genetik; medicinsk genetik; Medical Genetics;

   Sammanfattning : Lynch syndrome (Hereditary Nonpolyposis Colorectal Cancer, HNPCC) is the most common hereditary syndrome predisposing to colorectal cancer, accounting for 1-3% of all colorectal cancer. This multi-organ cancer predisposition syndrome is caused by mutations in the mismatch repair (MMR) genes, especially MLH1 and MSH2, and to lesser extents MSH6 and PMS2, which lead to widespread genetic instability and thus microsatellite instability (MSI).

3. 17. Approaches for analysis of mutations and genetic variations

   Författare :Afshin Ahmadian; KTH; []
   Nyckelord :LOH; microsatellite; fragment analysis; DNA sequencing; pyrosequencing; cancer; mutation; variation; SNP; allele-specific extension; apyrase; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Detecting mutations and genomic variations is fundamental indiagnosis, isolating disease genes, association studies,functional genomics and pharmacogenomics. The objective hasbeen to use and further develop a variety of tools andtechnologies to analyze these genetic alterations andvariations. LÄS MER

4. 18. Morphological Features and Mismatch Repair in Colorectal Tumors

   Författare :Britta Halvarsson; Tumörmikromiljö; []
   Nyckelord :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;

   Sammanfattning : 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.

5. 19. Gut microbiota in colorectal cancer : The importance of Parvimonas micra

   Författare :Thyra Löwenmark; Richard Palmqvist; Sofia Edin; Pär Larsson; Michael Dahlberg; Per Hellström; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; mucosal microbiota; Parvimonas micra; Fusobacterium nucleatum; immunity; survival; biomedical laboratory science; biomedicinsk laboratorievetenskap;

   Sammanfattning : Colorectal cancer (CRC) is a heterogenous disease consisting of multiple molecular subtypes, each of which has diverse treatment responses and prognoses. The importance of the gut microbiota in CRC development and progression has undergone increasing recognition in recent years, with a structural segregation in terms of microbial composition between CRC patients and healthy controls.

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; DNA methylation; folate; microsatellite instability MSI ; prognosis; risk factors; t-lymphocytes; the CpG island methylator phenotype CIMP ; Vitamin B12; Pathology; Patologi; Tumour biology; Tumörbiologi; patologi; Pathology;

   Sammanfattning : Background Colorectal cancer (CRC) is the second most common malignancy in developed countries. The mortality is high, with nearly half of patients dying from the disease. The primary treatment of CRC is surgery, and decisions about additional treatment with chemotherapy are based mainly on tumor stage. LÄS MER
