Parp1 Modulates Gata3-Mediated Gene Regulation In Breast Cancer, Mikhala Cooper
Theses and Dissertations
In eukaryotic cells, chromatin acts as a physical barrier for many transcription factors, preventing them from efficiently binding to their recognition sequences within the nucleosome. Pioneer factors are a class of transcription factors that bind to nucleosomes and activate silent chromatin. Pioneer factors are frequently involved in various immune cell pathways, tissue development, and homeostasis, thereby underscoring their important roles in development and disease. Previous research found that pioneer factors have at least three fundamental properties: 1) they can interact with their cognate recognition sequences before transcription activation, 2) they can increase local chromatin accessibility, and 3) they have integral …
