Differently from BRAF-like PTCs, RAS-like tumours show higher levels of the inducible transporter SLC2A4 (alias Glut4; Fig. 1b) and of its main regulator, the transcription factor SLC2A4RG (Fig. 1c), whose expression levels are positively correlated across tumour samples (Fig. 1d). The gene discussed is BRAF; the disease is neoplasm.
