All cases with missing information were included in proportional hazard ratio calculations after performing a sensitivity analysis which showed negligible effects of excluding missing data.ImmunohistochemistryImmunohistochemical staining for CNKSR1 (mouse monoclonal antibody CNKSR1 (clone 46), Santa Cruz Biotechnology, TX, USA, #sc-135,870; dilution 1:200) was performed on a Leica BOND-M

Ibed above. With phosphorylation of extracellular-signalregulated kinase (ERK) inducing nuclear translocation staining was predominantly nuclear with a few cases also showing cytoplasmic staining. Scoring of p-ERK1/2 was done blinded to the CNKSR1 results using standard intensity scores above (0 = no staining, 1 = weak staining, 2 = moderate staining, 3 = strong staining). In addition, the percent

Radial migration assay was performed as previously described [30,31]. In a blinded fashion, various U87Gal-1 clones were analyzed and compared to U87GFP controls and parental U87MG cells. Of each clone, 2500 cells were allowed to sediment through a cooled manifold onto laminin-coated cell culture wells (Creative Scientific Methods, Inc., Phoenix, AZ). The manifold and slide were incubated together
