Fig. 2From: In vivo evaluation of two tissue transglutaminase PET tracers in an orthotopic tumour xenograft modelTransglutaminase mRNA expression in MDA-MB-231 tumour cells and in MDA-MB-231 tumour tissue. Results are expressed as relative values to GAPDH mRNA expression ± standard deviation (n = 4; **p < 0.005; ***p < 0.0005)Back to article page
