A leading risk factor for cervical cancer (CC) initiation and progress includes human papillomavirus (HPV) infection. The telomerase catalytic subunit which regulates senescence and proliferation (carcinogenesis) is encoded by human telomerase reverse transcriptase (hTERT) gene. Our objective was the assessment of high risk HPV genotypes (16, 18 and 31) association with two polymorphisms of hTERT gene (rs2736098 and rs2736100) in CC development. Forty CC specimens were retired and 49 blood samples from healthy individuals were used as control group. The PCR-RFLP was performed for the detection of rs2736098 and rs2736100 polymorphisms. The differences of A, C or G alleles were not significant between case and control. Accordingly, among 10 high risk HPV genotypes, genotype 18 was detected and there was no meaningful relation between neither the hTERT rs2736098 nor the rs2736100 polymorphisms and CC risk.
Abstract
The glutathione S-transferase (GST) is a polymorphic supergene family of detoxification enzymes that are involved in the metabolism of potential carcinogens. To evaluate the association between polymorphisms in the GSTs (GSTT1, GSTM1 and GSTP1) and basal cell carcinoma (BCC), 50 BCC patients and 50 healthy ...

The glutathione S-transferase (GST) is a polymorphic supergene family of detoxification enzymes that are involved in the metabolism of potential carcinogens. To evaluate the association between polymorphisms in the GSTs (GSTT1, GSTM1 and GSTP1) and basal cell carcinoma (BCC), 50 BCC patients and 50 healthy controls were studied. Based on our findings, the frequencies of GSTM1 null genotype in patients and controls were 34 % and 6 %, respectively. Furthermore, the overall frequency of GSTT1 null genotype was higher than in the BCC patients compared to the control samples. The strongest association was observed between GSTP1 polymorphism and BCC in the population. Genotype mixture of GSTM1 and GSTT1 showed a higher risk of developing BCC in subjects with one null genotype. This study suggested a reasonable association between GST polymorphisms and BCC susceptibility among Iranian population.
