Role Of Ddr1 In Pancreatic Cancer, Huocong Huang
Theses & Dissertations
Pancreatic ductal adenocarcinomas are highly malignant cancers, characterized by extensive invasion into surrounding tissues, metastasis to distant organs at a very early stage, and a limited response to therapy. One of the main features of pancreatic ductal adenocarcinomas is desmoplasia, which leads to extensive deposition of collagen I. We have demonstrated that collagen I can induce epithelial-mesenchymal transition (EMT) in pancreatic cancer cells. A hallmark of EMT is an increase in the expression of a mesenchymal cadherin, N-cadherin. Our previous studies have shown that up-regulation of N-cadherin can promote tumor cell invasion and that collagen I-induced EMT is through two …

Secretory Mucin Muc5ac In Gastrointestinal Malignancies, Shiv Ram Krishn
Theses & Dissertations
Secretory mucin MUC5AC is an extensively glycosylated high molecular weight protein that forms a polymeric gel layer over the epithelial layers under physiological conditions, to protect these surfaces from myriad of insults. MUC5AC is known to be implicated in various malignancies including pancreatic cancer and colorectal cancer. MUC5AC is overexpressed in pancreatic cancer compared to no expression in normal pancreas. However, its functional implications and associated mechanistic basis in pancreatic cancer remains obscure. Therefore, we investigated the role of MUC5AC in onset and progression of pancreatic cancer. Our study showed that MUC5AC expression is elevated during pancreatic cancer progression while …
