The Role Of Oncogenic Kras In Initiation, Progression And Maintenance Of Pancreatic Cancer, Nirakar Rajbhandari May 2016

The Role Of Oncogenic Kras In Initiation, Progression And Maintenance Of Pancreatic Cancer, Nirakar Rajbhandari

Theses & Dissertations

Pancreatic cancer is a lethal disease that is almost invariably associated with a KRAS gene mutation. Due to a very high frequency of gain-of-function mutations within the KRAS gene, and its proven role in initiation of pancreatic cancer in animal models, mutant KRAS is considered a rational therapeutic target. To determine the potential role of oncogenic KRAS in pancreatic tumor maintenance in vivo, we generated a mouse model with a Doxycycline regulated expression of oncogenic KRAS (KRASG12D) in pancreas. Using this reversible model, we demonstrated that the expression of oncogenic KRAS in a Cdkn2a deficient background was …


Novel Regulatory Mechanisms And Functions Of Muc4 In Pancreatic Cancer, Suhasini Joshi May 2016

Novel Regulatory Mechanisms And Functions Of Muc4 In Pancreatic Cancer, Suhasini Joshi

Theses & Dissertations

Mucins are high molecular weight glycoproteins and have critical functions in protecting epithelial cells from a myriad of cellular stress. However, mucins are expressed aberrantly under cancer conditions that allow tumors to progress and metastasize. Among many mucins, Mucin 4 (MUC4) serves as one of the top-differentially expressed proteins in pancreatic cancer (PC), however, the precise mechanism responsible for its aberrant expression is still not clear. The evolving view of cancer as an energetic and growing ecosystem underlines an intricate interplay between cancer and its microenvironment. In spite of being recognized as one of the most critical oncogenic proteins in …
