Inactivation of tumor suppressors genes, which encode regulatory proteins critical for maintaining normal cellular function, is a common occurrence in cancer. Ikaros is a hematopoietic-specific zinc finger protein that functions as a differentiation regulator and has properties of a tumor suppressor. Ikaros functions to regulate gene expression as a component...
The nervous system develops through the highly regulated process of proliferation and differentiation of neural stem cells. Two major regulatory pathways that maintain neural stem cells in a proliferative state or promote their differentiation are the Notch and BMP signaling pathways, respectively. In this dissertation, we demonstrate that HeyL, a...
