Gene expression analysis of cervical cancer progression

ABSTRACT: Affymetrix-U133-plus2.0-based gene expression analysis of laser-captured epithelium from 128 cervical tissue specimens from women enrolled in SUCCEED Cervical cancer (CC) is the second most frequent cancer in women and the third leading cause of cancer death in women worldwide. Our analysis of normal, precancerous, and cancerous cervical tissue shows that progress of the disease is a cascade of increased DNA replication/repair and cell proliferation followed by substantial metabolic shifts. The data show a sharp decrease in estrogen receptor alpha (ERα) in tumor cells, and ranking tissue specimens by estrogen-responsive gene expression correlates remarkably closely with histological pathology.

Bio-cRNA was hybridized to Affymetrix U133-Plus2.0 arrays, scanned signals were processed through GC-RMA

To study the multistep process of cervical cancer development, we analyzed 128 frozen cervical samples spanning normalcy, increasingly severe cervical intraepithelial neoplasia (CIN1- CIN3), and cervical cancer (CxCa) from multiple perspectives, revealing a cascade of progressive changes. Compared with normal tissue, expression of many DNA replication/repair and cell proliferation genes was increased in CIN1/CIN2 lesions and further sustained in CIN3, consistent with high-risk human papillomavir  ...[more]
