Description: The objective of this project was to use high resolution microarray comparative genomic hybridization (CGH) to identify differentiating regions of genomic imbalance between epithelial ovarian tumors resistant and sensitive to chemotherapy. Our analysis has confirmed the presence of copy number alterations At specific chromosomal loci in these tumors. Gains at 1q, 3q, 8q, 12p and 20q as well as losses at 1p, 4q, 6q, 8p, 9q, 13q, 16q 17p, 18q, are consistent with reported changes in the literature. The improved resolution of array CGH has further allowed us to determine important discriminating regions in these two tumor sets. These regions include 1q42.3, 6q25.3, 13q12.3 and 17q25.3. Two of these regions have been identified in previous work and another contains a gene identified as playing a role in chemotherapy response. Once refined, these regions may be used as markers to identify resistance to chemotherapy prior to initiation of treatment.
