Pancreatic ductal adenocarcinoma (PDAC) is a highly metastatic malignancy that is the fourth leading cause of cancer death in the United States, with an overall five year survival rate of less than six percent (Siegel et al >>2011<<). PDAC exhibits a wide range of genetic and epigenetic alterations including a high frequency (90-95%) of activating Kras mutations, homozygous deletion (85%) and epigenetic silencing (15%) of the tumor suppressor genes p16INK4A/p14ARF

To assess the impact of GPC1 on the expression levels of VEGF-A and GPC2-6, total RNA was isolated from tumors arising in 60 day old GPC1+/+ and 5 GPC1-/- mice, using the low temperature guanidine isothiocyanate method (Chang et al >>1990<<, Han et al 1987). The concentration of RNA was determined spectrophometrically and RNA integrity was verified on a 1% agarose gel.
