  1. 1. Biomarkers of one-carbon metabolism in colorectal cancer risk

    Författare :Björn Gylling; Richard Palmqvist; Katarina Bälter; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; one-carbon metabolism; biomarkers; folate; epidemiology; Cancer Epidemiology; cancerepidemiologi;

    Sammanfattning : One-carbon metabolism, a network of enzymatic reactions involving the transfer of methyl groups, depends on B-vitamins as cofactors, folate as a methyl group carrier, and amino acids, betaine, and choline as methyl group donors. One-carbon metabolism influences many processes in cancer initiation and development such as DNA synthesis, genome stability, and histone and epigenetic methylation. LÄS MER

  2. 2. Metabolic Risk Factors and Molecular Subtypes of Colorectal Cancer

    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; risk factors; metabolic syndrome; one-carbon metabolism; molecular subtypes; KRAS; BRAF; MSI; molecular pathological epidemiology; Cancer Epidemiology; cancerepidemiologi;

    Sammanfattning : Background: Colorectal cancer (CRC) is a heterogeneous disease developing from distinct pathways, resulting in tumor subtypes with large differences in clinical and molecular characteristics. Molecular characteristics are increasingly being used clinically to guide therapy. LÄS MER

    Sammanfattning : BackgroundColorectal cancer (CRC) – i.e., cancer in the colon or rectum – is one of the most common cancers both globally and in Sweden. The risk for CRC is mainly related to age, heredity, and life-style risk factors. LÄS MER

  4. 4. Prospective studies of hormonal and life-style related factors and risk of cancer

    Författare :Sara Wirén; Pär Stattin; Håkan Jonsson; Tanja Stocks; Alicja Wolk; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; epidemiology; androgens; risk factors; fatherhood status; dizygotic twins; height; cohort; case-control; prospective; Cancer Epidemiology; cancerepidemiologi;

    Sammanfattning : Background: Androgens are important in prostate cancer development but how circulating levels of androgens affect risk of prostate cancer of different aggressiveness is not clear. Being childless has been associated with a lower risk of prostate cancer, but it is not clear if this association is causal or a result of residual confounding. LÄS MER
