Levels of EPOR transcripts were also not elevated in brain tumours relative to normal brain (Figure 3C), colon and lung adenocarcinomas relative to patient-matched normal tissue (Figure 3D), and laser-dissected tumour epithelia from head and neck tumours relative to stroma (samples collected from three different regions from each tumour A–C, Figure 3E). Here, EPOR is linked to brain neoplasm.
