Individuals with at least one copy of the following risk alleles: T of SNP (-590C > T IL-4), C of SNP (-573G > C IL-6), A of SNP (-592C > A IL-10), T of SNP (-819C > T IL-10) and T of SNP (-509C > T TGFB1), had an adjusted odds ratio (OR) of 2.08 (95 % CI 1.475-2.934, p = 0.0001), an OR of 1.70 (95 % CI 1.208-2.404, p = 0.002), an OR of 1.87 (95 % CI 1.332-2.630, p = 0.0001), an OR of 1.67 (95 % CI 1.192-2.353, p = 0.003) and an OR of 1.91 (95 % CI 1.354-2.701, p = 0.0001), respectively, for CC.
This study suggests that passive smokers among North Indian women having IL-4 Rp1/Rp2 and IL-10 (AC) genotypes had an increased risk for developing cervical cancer.
Our data therefore suggest that IL-4 and IL-13 may play a role in the biosynthesis of active sex steroids from the inactive adrenal steroid dehydroepiandrosterone, not only in breast cells but also in various cell types derived from peripheral target tissues, such as normal human prostate epithelial cells, immortalized keratinocytes, as well as colon and cervix cancer cell lines.
