Pathologists (MM, MA). CNKSR1 low (0 and 1 + expression) versus CNKSR1 high (2+, 3+) comprised 28.3 and 71.7 of cases in the study cohort and 44.1 and 55.9 of cases in the validation cohort suggesting similar expression patterns across the different arrays. In the study cohort 30 of cases also showed some degree of nuclear staining (Fig. 5b). Nuclear staining was lower than cytoplasmic expressi

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

Nostic marker using multivariate analysis, with patients in the low CNKSR1 expression group having a median OS that is nearly half that of patients with high CNKSR1 expression. In addition, we attempted to determine whether CNKSR1 status might affect the survival difference associated with resection in pancreatic cancer patients. If validated in a larger patient sample, such information might be u

In spite of this variability, the quality of the RNA was consistently high with a mean RNA integrity number of 8.13 ?0.74. Expression

Galectin-1 transfectants. A population of GFP-sorted cells (the "Gal-1" bars in Figure 4A) was compared to its parental counterpart. The number of metabolically-active cells attached to fibronectin was no different between the two lines at eight hours. Changing the media at four hours reduced the number of cells left for labeling, but the effect was equal in both groups, suggesting a similar rate
