Q-RT-PCR and Western blot analyses of EPOR expression in oral squamous cell carcinoma (OSCC). (A) The mRNA expression level of EPOR was determined by Q-RT-PCR in 12-paired OSCC patients (from early tumor stage to late tumor stage). Results were normalized against the expression level of GAPDH mRNA in each sample. (B) The Western blot analysis showed high EPOR expression in the tumor tissue compared with that in the adjacent non-tumor tissue in 8-paired tissue samples (from early tumor stage to late tumor stage). β-Actin was used as an internal control. EPOR, erythropoietin receptor; N, adjacent non-tumor tissue; T, tumor tissue.
