摘要: Since the majority of high-grade breast cancers express reduced levels BRCA1 mRNA, we investigated factors regulating transcription. Factors with specific affinity for previously identified positive regulatory region (PRR) in promoter were purified from whole-cell extracts. Identified proteins included replication protein A and a series related sense strand PRR. subset activated promoter. Identification these families represents an important step comprehension mechanisms responsible cancer development.
