Compromised activity of the DNA repair enzymes may raise the risk of a number of cancers. We analyzed polymorphisms in the Xeroderma Pigmentosum, Complementation Group C (XPC) gene for their correlation with urinary bladder cancer. Ala499Val and Lys939Gln polymorphisms were genotyped in 234 urinary

BACKGROUND Interleukin-6 is a multifunctional cytokine, which plays a key role in tumor proliferation and differentiation. Variations in its gene (IL6) sequence may affect the risk of developing various cancers, including urinary bladder cancer. The present study was done to find the association of
