As shown in Fig 1E, high SEMA3C mRNA levels were associated with increased levels of phospho‐EGFR (Y1068), phospho‐ErbB2 (Y1248), phospho‐SRC (Y416), and phospho‐SHC (Y317) as determined by reverse‐phase protein array (RPPA) measurements of phosphoprotein levels in patient tumor samples expressing increased SEMA3C mRNA with z‐score threshold >1.0 (SEMA3C high) versus unaltered SEMA3C (SEMA3C low) tumor samples from TCGA prostate adenocarcinoma provisional data set. Here, SHC1 is linked to prostate adenocarcinoma.
