Role Of Ezrin In Colorectal Cancer Cell Survival Regulation, Premila Leiphrakpam Dec 2017

Role Of Ezrin In Colorectal Cancer Cell Survival Regulation, Premila Leiphrakpam

Theses & Dissertations

Colorectal cancer (CRC) is the second most common cause of cancer related deaths in the United States, mainly due to metastasis to the distant organ sites. However, the molecular basis of CRC metastasis is poorly understood. Therefore, identification and characterization of novel potential anti-cancer therapeutic targets CRC is of urgent need. Utilizing a 2D-DIGE proteomics approach ezrin was identified as a protein that is differentially expressed between primary colon tumors xenografts, orthotopically implanted in athymic nude mice, and corresponding and liver metastatic deposits. Ezrin, a cytoskeletal protein belonging to the ezrin–radixin–moesin (ERM) family plays important roles in cell ...


Regulation Of The Transmembrane Mucin Muc4 By Wnt/Β-Catenin In Gastrointestinal Cancers, Priya Pai Dec 2015

Regulation Of The Transmembrane Mucin Muc4 By Wnt/Β-Catenin In Gastrointestinal Cancers, Priya Pai

Theses & Dissertations

The transmembrane mucin MUC4 is a high molecular weight glycoprotein that is expressed de novo in pancreatic ductal adenocarcinoma (PDAC). MUC4 has been shown to play a tumor-promoting role in malignancies such as PDAC, ovarian cancer and breast cancer. Unlike the normal pancreas, MUC4 is ordinarily expressed by goblet and absorptive cells in the normal colonic epithelium. However, its expression/role in colorectal cancer (CRC) is not well studied.

In this dissertation, the goal was to identify factor(s) that may differentially regulate MUC4 in these two disparate malignancies. Furthermore, in light of its pro-tumorigenic role in other malignancies, we ...
