In addition to our studies showing that DUSP26 clearly dephosphorylates p38, multiple other studies have shown p38 dephosphorylation with DUSP26 overexpression.18, 20, 21 As far as expression in NB, our group has clearly shown by immunohistochemistry that DUSP26 is overexpressed in NB tissue samples versus normal adrenal gland controls particularly in high-risk patients. This evidence concerns the gene MAPK14 and neuroblastoma.
