KDM4D expression is elevated in GIST tissue. a KDM4D expression was examined in normal and GIST tissues from the Oncomine public data set. b, c KDM4D protein expression in normal and GIST tissues was analysed by western blot b. KDM4D protein expression was quantified using Image J software (c). d KDM4D mRNA expression was detected in normal and GIST tissues. e KDM4D protein expression in normal and GIST tissue was analysed by IHC. f The association between KDM4D expression and GIST tissue type was assessed using Pearson’s χ² test
