Notch-1 Specifically Activates Erk1/2 In Multiple Breast Cancer Subtypes, Allison Schuyler Rogowski

Master's Theses

Notch-1 is a cell fate regulatory protein and a potent breast oncogene. Notch-1 and its ligand Jagged-1 are over-expressed in human breast cancers that are associated with poor overall survival (Reedijk, Odorcic et al. 2005). Deregulated Notch signaling may contribute to tumorigenesis by increasing proliferation, inhibiting differentiation, and preventing apoptosis (Miele, Golde et al. 2006). The mitogen-activated protein kinase (MAPK) pathway is a critical cell signaling pathway that has been implicated in the development and progression of cancer (Hanahan and Weinberg 2000). Four major MAPK pathways are involved in both cell growth and apoptosis. The regulation of these pathways is …
