Pharmacogenetics of DNA repair gene polymorphisms in non-small-cell lung carcinoma patients on platinum-based chemotherapy

L. Zhang, Ma, W., Li, Y., Wu, J., and Shi, G. Y., Pharmacogenetics of DNA repair gene polymorphisms in non-small-cell lung carcinoma patients on platinum-based chemotherapy, vol. 13, pp. 228-236, 2014.

Individual differences in chemosensitivity and clinical outcome of non-small-cell lung carcinoma (NSCLC) patients can be influenced by host-inherited factors. We investigated the impact of XRCC1 Arg194Trp, XRCC1 Arg280His, XRCC1 Arg399Gln, XPD Arg156Arg, XPD Asp312Asn, XPD Asp711Asp, and XPD Lys751Gln gene polymorphisms on treatment efficacy in 375 NSCLC patients on platinum-based chemotherapy. We also examined progression-free survival and overall survival. The gene polymorphisms were analyzed by duplex PCR.

Implication of polymorphisms in DNA repair genes with an increased risk of hepatocellular carcinoma

J. S. Wu, Chen, Y. P., Wang, L. C., Yang, Y. J., Deng, C. W., Hou, B. X., He, Z. L., and Chen, J. X., Implication of polymorphisms in DNA repair genes with an increased risk of hepatocellular carcinoma, vol. 13, pp. 3812-3818, 2014.

We explored the association between 4 XRCC1 (Arg194Trp and Arg399Gln) and XPD (Asp312Asn and Lys751Gln) polymorphisms with the development and prognosis of hepatocellular carcinoma (HCC). A total of 218 cases with HCC and 277 healthy controls were included in the study. Genotyping of the XRCC1 (Arg194Trp and Arg399Gln) and XPD (Asp312Asn and Lys751Gln) polymorphisms was performed in a 384-well plate format on the Sequenom MassARRAY platform.

Association between XPD Lys751Gln polymorphism and risk of head and neck cancer: a meta-analysis

H. Yuan, Niu, Y. M., Wang, R. X., Li, H. Z., and Chen, N., Association between XPD Lys751Gln polymorphism and risk of head and neck cancer: a meta-analysis, vol. 10, pp. 3356-3364, 2011.

Several studies have investigated the association between Lys751Gln polymorphism in the xeroderma pigmentosum group D (XPD) gene and risk of head and neck cancer; however, the published results are conflicting. We conducted a meta-analysis that comprised 15 published case-control studies examining the association of head and neck cancer risk with XPD Lys751Gln polymorphism in different populations, based on the data identified in Medline up to November 2010. Odds ratios (ORs) with 95% confidence intervals (CI) were used to assess the strength of the association.

XPD and hOGG1 gene polymorphisms in reperfusion oxidative stress

O. İsbir, Gormus, U., Ergen, H. A., Cakmakoglu, B., Kahraman, Ö. T., and Baykan, N., XPD and hOGG1 gene polymorphisms in reperfusion oxidative stress, vol. 10, pp. 3157-3162, 2011.

Knee replacement surgery is an ischemia/reperfusion model, as it uses tourniquet applied to the knee area to stop the blood flow during the operation. Fifty patients that were undergoing elective arthroscopic knee surgery were included in our study. Human 8-oxoguanine glycosylase 1 (hOGG1) is an enzyme to repair specific DNA lesions and a good marker of hydroxyl radical damage to DNA. XPD is another DNA repair gene. We investigated the effect of hOGG1 (Ser326Cys) and XPD (Lys751Gln) polymorphisms on the oxidative stress level after reperfusion.
