  1. Association of Prostate cancer risk with genetic polymorphisms in vitamin D receptor and androgen receptor.

    Article - En anglais

    Background 

    Prostate cancer is an increasingly common disease for which there are few well-established risk factors.

    Family history data suggest a genetic component ; however, the majority of prostate cancer cases cannot be explained by a single-gene model.

    Prostate cell division is influenced by two steroid hormones, testosterone and vitamin D, the action of each being mediated by its respective receptor.

    The genes for the two receptors are candidates in a multigenic model for prostate cancer susceptibility.

    Purpose 

    We examined genetic polymorphisms in two steroid receptors, the androgen receptor (AR) and the vitamin D receptor (VDR), in a case-control pilot study of prostate cancer.

    Methods 

    Fifty-seven non-Hispanic white case patients with prostate cancer and 169 non-Hispanic white control subjects were genotyped for a previously described microsatel-lite (CAG repeats) in the AR gene and for a newly discovered poly-A micro-satellite in the 3'-untranslated region (3'UTR) of the VDR gene.

    To compare genotypes with respect to prostate cancer risk, we estimated odds ratios (ORs) by using logistic regression.

    ORs were also estimated separately for advanced and localized cases of disease.

    All P values resulted from two-sided tests.

    Results 

    Both the AR and the VDR polymorphisms were associated, individually and after mutual adjustment, with prostate cancer.

    Adjusted ORs (95% confidence intervals [CIs]) for prostate cancer were 2.10 (95% CI=1.11-3. (...)
