Y intensity of p-ERK immunostaining. Figure 8C shows nuclear p-ERK expression levels (0, 1+, 2+, 3+)) by CNKSR1 cellular distribution (cytoplasmic CNKSR1 expression only vs cytoplasmic and nuclear) in pancreas cancer specimens of the SEER Pancreatic Cancer TMA (Mann Whitney U test; p = 0.017). To test whether expression levels of the two proteins are correlated as well, including if a possible neg
