Aberrant Glycosylation In Pancreatic Cancer Progression, Seema Chugh May 2017

Aberrant Glycosylation In Pancreatic Cancer Progression, Seema Chugh

Theses & Dissertations

Aberrant changes in O-glycosylation patterns underlie pancreatic ductal adenocarcinoma (PDAC) progression and metastasis. Glycosylation is a post-translational modification in which carbohydrate moieties are attached to the protein substrate. My dissertation is focused on mucin-type O-glycosylation, which is the predominant form of O-glycosylation and is regulated by a myriad of glycosyltransferases.

PDAC is one of the most lethal diseases and the mechanistic involvement of aberrant O-glycosylation in its progression and metastasis is unknown. The aberrant glycosylation refers to the appearance of unusual carbohydrate structures such as truncated carbohydrate antigens, often referred to as tumor-associated carbohydrate antigens.

In this dissertation, my goal ...
