Abstract

Background:Dysregulation of the cell cycle is a hallmark of many cancers including ovarian cancer, a leading cause of gynaecologic cancer mortality worldwide.Methods:We examined single nucleotide polymorphisms (SNPs) (n288) from 39 cell cycle regulation genes, including cyclins, cyclin-dependent kinases (CDKs) and CDK inhibitors, in a two-stage study. White, non-Hispanic cases (n829) and ovarian cancer-free controls (n941) were genotyped using an Illumina assay.Results:Eleven variants in nine genes (ABL1, CCNB2, CDKN1A, CCND3, E2F2, CDK2, E2F3, CDC2, and CDK7) were associated with risk of ovarian cancer in at least one genetic model. Seven SNPs were then assessed in four additional studies with 1689 cases and 3398 controls. Association between risk of ovarian cancer and ABL1 rs2855192 found in the original population odds ratio, OR BB vs AA 2.81 (1.29-6.09), P0.01 was also observed in a replication population, and the association remained suggestive in the combined analysis OR BB vs AA 1.59 (1.08-2.34), P0.02. No other SNP associations remained suggestive in the replication populations.Conclusion:ABL1 has been implicated in multiple processes including cell division, cell adhesion and cellular stress response. These results suggest that characterization of the function of genetic variation in this gene in other ovarian cancer populations is warranted.
