We conducted a case-control study to investigate the role of common SNPs in ERCC2 (rs13181 and rs1799793) and ERCC3 (rs4150441 and rs4150506) in the development of osteosarcoma. A 1:2 matched case-control study was conducted. Between January 2012 and December 2013, 141 patients with pathologically diagnosed osteosarcoma and 282 controls were recruited in our study. Genotyping of ERCC2 rs13181 and rs1799793 as well as ERCC3 rs4150441 and rs4150506 were performed using polymerase chain reaction coupled with restriction fragment length polymorphism.
We conducted a study to investigate the association between ERCC1 (rs3212986) and ERCC2 (rs13181) gene polymorphisms and the risk of pancreatic cancer in a Chinese population. A total of 217 pancreatic cancer patients and 244 control subjects were recruited from the Nuclear Industry 215 Hospital of Shaanxi Province between February 2013 and December 2014. Genomic DNA was extracted from peripheral blood samples using a TIANamp Blood DNA Kit (Tiangen, Beijing, China) according to the manufacturer’s instructions.
