Mucin And Splice Variant Profiles Of Pancreatic Adenocarcinoma Predict Patient Survival And Subtyping, Christopher M. Thompson
Mucin And Splice Variant Profiles Of Pancreatic Adenocarcinoma Predict Patient Survival And Subtyping, Christopher M. Thompson
Theses & Dissertations
PDAC is a pancreatic epithelial malignancy and demonstrates aggressive progression and bleak patient prognosis. Despite decades of research, the evolution of novel diagnostics and intervention modalities for PDAC is stagnant. This dissertation explores the characteristic aberrant and elevated expression of mucins in PDAC. Beginning with the hypothesis that mucins are associated with disease aggressiveness, analysis of PDAC patient survival in TCGA revealed no associations between single mucin expression and patient survival. This led to the underlying issue of PDAC tumor cellularity since this disease demonstrates variability in the proportion of cancer cells within the tumor. Tumor purity assessed with the …

The mucosal layer that shields the epithelium of the body cavities is made up of high molecular weight, heavily glycosylated proteins called mucins that are broadly categorized into transmembrane and secreted members. Aberrant expression of secreted mucin MUC5AC has been implicated in lung, stomach, and colon cancer pathologies. MUC5AC is expressed de novo in the pancreas upon oncogenic insult, and its abundance in pancreatic tumor and circulation correlates to disease progression. However, few studies have explored beyond the diagnostic and prognostic significance of MUC5AC in pancreatic cancer (PC).
In this dissertation, we sought to investigate the mechanistic contribution of MUC5AC …
