Basic Pancreatic Cancer 110 Nestin-Positive Cells in the Pancreas – Precursor Cell for Pancreatic Adenocarcinoma? T. Kennedy, X.Z. Ding, T.E. Adrian, R.H. Bell Jr Department of Surgery, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA Introduction: The cell type of origin for development of pancreatic adenocarcinoma is controversial. While pancreatic cancers cells behave like ductal cells, other evidence sug- gests that islet or acinar cells may be the origin. Recently, a new pancreatic cell type was characterized as a nestin-positive stem cell. These nestin-positive cells have extended proliferative capacity in culture and are capable of differentiating into multiple cell types. We hypothesize that this nestin-positive cell is the origin for pancreatic adenocarcinoma. Materials and Methods: RT-PCR was performed on RNA extracted from pancreatic ...

Basic Pancreatic Cancer 116 Gene Therapy for Pancreas Cancer with a Genetically Engineered Tumour Suppressor MTBP N. Eardley, N. Vlatkovic, M.T. Boyd University of Liverpool, UK Background: Whilst studying the regulation and function of MDM2 we discovered a novel MDM2 binding protein with potent tumour cell inhibitory properties that we named MTBP (Boyd et al. JBC 2000). We have since discovered that ectopic expression of this gene inhibits pancreatic cancer cell growth comparably to p53. We have now developed a truncated form of the protein that lacks a negative regulatory element and which has enhanced tumour cell growth inhibitory activity. Methods: Full length MTBP and deletion mutants of MTBP expressed from a CMV promoter in a eukaryotic expression vector were tested for their ability to inhibit colony formation in a variety of tumour cell lines including ...
