Quantitative PCR estimation of
expression in GIST. Relative expression of ERG (upper left panel), NTRK2 (upper right panel), CALCRL (lower left panel) and COL22A1 (lower right panel) mRNA in the two KIT
WT GIST in respect to the others molecular subgroups (4 SDHx
mut, 19 KIT
mut and 10 PDGFRA
mut GIST). Significance was estimated by the Student T-test: *p-value < 0.05; **p-value < 0.01; ***p-value < 0.001.
