The mRNA and protein expression levels of WASF2 for the same cell line showed a high positive correlation (Pearson’s correlation coefficient r = 0.79, P = 0.006; Fig. 1J) We performed IHC analysis on non-tumor and tumor tissues from patients, in cases where archived tissue was available, to confirm the expression of the putative marker, WASF2, indicated as brown spots corresponding to positive antibody staining. This evidence concerns the gene WASF2 and neoplasm.
