Deep Sequencing of the Breast Cancer Transcriptome
This project is a pilot study designed to investigate transcriptional regulation in breast cancer. Although the main focus of the present study will be triple negative breast cancer where all of the clinically relevant receptors - estrogen receptor (ER), progesterone receptor (PR) and herceptin (HER2) - are absent, all breast tissue biospecimens, including normal and mammary dysplasia, stored in the UAMS Tissue bank, procured from outside collaborators or purchased from commercial vendors will eventually be investigated. We will use high throughput molecular profiling techniques such as microarrays and next generation sequencing to correlate gene expression and gene expression regulation with clinical parameters such as tumor size, time to relapse and overall survival.
|Study Design:||Observational Model: Case-Only
Time Perspective: Retrospective
|Official Title:||Deep Sequencing of the Breast Cancer Transcriptome|
The informed consent process for biospecimen collection we expect to use in this research has already been obtained by the UAMS Tissue Bank personnel as a part of the UARK 2005-06 protocol. Tissue is collected during biopsies or mastectomies after pathologist approval. We will sequence small non-coding molecules (microRNA), messenger RNA, chromatin immunoprecipated and bisulfite treated DNA.
|Study Start Date:||September 2009|
|Study Completion Date:||December 2013|
|Primary Completion Date:||December 2013 (Final data collection date for primary outcome measure)|
Tissue Bank Samples
Because this study is a retrospective tissue bank study, there are no subjects actively participating in this study. All samples studied will be obtained through the UAMS Tissue Bank.
Other: No intervention
Because this study is a retrospective tissue bank study, there are no subjects actively participating in this study, thus no intervention. All samples studied will be obtained through the UAMS Tissue Bank.
