RT-PCR showed that the expression of GLUT-1 (A), HIF-1α (B), p-Akt (C), and PI3K (D) mRNA were high than these in precancerous lesion and laryngeal squamous cell carcinoma. Akt = protein kinase B, GLUT-1 = glucose transporter-1, HIF-1α = hypoxia-inducible factor-1α, PI3K = phosphatidylinositol 3-kinase, RT-PCR = reverse transcription-polymerase chain reaction.
