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 …

The differentiation of CD4+ T cells to different effector lineages in response to pathogenic stimuli is the core of the adaptive immune system. One of the effector subsets recently discovered is Thelper 17 (Th17) and it plays a predominant role in autoimmune diseases and inflammatory disorders.
In my thesis, I aimed to study the role of Notch cell surface receptors in Th17 differentiation. Using in vitro Th17 differentiation assays of human naïve CD4+ T cells, I have shown that Notch signaling, particularly Notch1, plays a crucial role in Th17 polarization. By using pharmacological inhibitors and specific knockdown of Notch1, I …
