MT1JP and neoplasm: Among these, we observed one that was down-regulated to less than 50% in all tumor samples compared to the matched normal tissues (Figure 1A), and this transcript has previously been labelled as MT1JP. As an additional test, we determined the abundance of MT1JP in another 29 pairs of tissue samples from liver, colon, lung and gaster cancer by quantitative real time polymerase chain reaction (qRT-PCR).
