Abbreviations: RKIP Raf kinase inhibitory protein, p-Ser153 RKIP RKIP in phosphorylated form at residue serine153, Ser serine
Note: P*, the p-Ser153 RKIP-positive expression versus the p-Ser153 RKIP–negative expression; P**, the comparison among 3 different staining scores of the p-Ser153 RKIP-positive expression
