Project description:Array comparative genomic hybridization characterization and comparison of cell lines from 9 different cancer tissue of origin types (Breast, Central Nervous System, Colon, Leukemia, Melanoma, Non-Small Cell Lung, Ovarian, Prostate, Renal) from NCI-60 panel.
Project description:We conducted a comprehensive genomic characterization of the cisplatin sensitive A2780 ovarian cancer cell line compared to A2780cis, its resistant derivative. The data includes eXcision Repair-sequencing (XR-seq) to map cisplatin repair,RNA-Seq to characterize gene expression and ATAC-Seq to detect changes in chromatin accessibility.
Project description:The identification and characterization of subpopulations of cancer stem cells (CSCs) provide new understandings and possible therapeutic implications in cancer biology. We found the ovarian cancer sphere cells possessed CSCs properties maintained self renewal, drug resistance, and tumorigenesis. Using high-throughput microarray system, we identified common GO terms and pathway signatures significantly enriched in ovarian and breast cancer stem cells. Ovarian and breast cancer cells were cultured in sphere formation conditions, and total RNA from those spheres and conresponding adhered cell was hybridized on Affymetrix microarrays.
Project description:The distinction between primary and secondary ovarian tumors may be challenging for pathologists. We performed transcriptomic analysis in order to discriminate between primary ovarian tumors and ovarian metastases after primary breast cancer. We performed genomic analysis on tumor paired samples (breast/ovary) in order to know if genomic profiles could help for the discrimination of primary ovarian tumors and ovarian metastases after primary breast cancer.
Project description:Purpose: There are three goals of this study of these analysis: 1. To compare the genomic, exome and chromatin accessiblity profiles of the specific engineered fallopian tube cells of high-grade serous tubo-ovarian cancer (HGSC) models (this study) using whole-exome-, whole-genome- and ATAC sequencing. Methods: Genomic DNA was extracted from the cell lines mentioned below. Conclusions: We conclude that whole-exome, whole-genome and ATAC-seq characterization would expedite genetic network analyses and permit the dissection of complex biological functions.

Project description:Characterization of differential gene expression due to cisplatin resistance in human ovarian cancer spheroids by microarray analysis. In this dataset, we include the expression data obtained from cisplatin-sensitive and cisplatin-resistant human ovarian cancer spheroids. These data are used to obtain 1316 genes that are differentially expressed in response to cisplatin resistance.
