Erved association of CNKSR1 expression and survival outcome suggests scaffolding proteins of the RAS-MAPK pathway may account, in part, for the observed heterogeneity of PDAC biology, and clinically may aid in improved future patient stratification.MethodsStudy participants and tissue microarray (TMA) compositionDe-identified cancer tissues included in this analysis were confirmed to be pancreatic

Enhancer of the Kinase Suppressor of Ras-1), a regulator and binding partner of KSR1, is another scaffolding protein which is less understood. Its role in pancreatic cancer biology, or as a biomarker, remains to be explored. Current data suggests that CNKSR1 has multiple roles cancer biology, with some reports demonstrating that CNKSR1 interacts with tumor suppressors and othersdescribe its scaffo

On began the day after transfection. When enough GFP-expressing cells were identified, single cell suspensions were sorted under sterile conditions using the GFP filters (488/530 nm excitation/emission) on a FACS Vantage Sorter (Beckton Dickinson Immunocytometry Systems, San Jose, CA). Cells were collected in 96-well plates at a setting of 2 cells / well, after attempts to collect 1 cell per well

One microliter of each eluted RNA sample was used for quantitation with the RiboGreen (Molecular Probes, Eugene, OR) assay kit. These total RNA samples were analyzed for integrity by obtaining electropherograms on an Agilent 2100 Bioanalyzer chip. Samples of acceptable quality based on RNA integrity numb
