Figure 3From: Presence of activating KRAS mutations correlates significantly with expression of tumour suppressor genes DCN and TPM1 in colorectal cancer Expression of DCN and TPM1 in pairs of samples with a different KRAS status. Expression is shown in ΔΔCT units, whereby a negative ΔΔCT value represents down-regulation of DCN, TPM1 in comparison to normal tissue. Pairs of samples were grouped according to their KRAS status.Back to article page
