Resumo:	Radiation Therapy (RT) is a treatment option for a large number of neoplasias. However, the effect of RT on the level of hypoxia markers is poorly understood. The present study aimed to investigate the effect of RT on the levels of hypoxic markers in Oral squamous cell carcinoma (OSCC). Evaluation of HIF-1α and miR-210 levels in OSCC was performed. Then a proteomic analysis was performed to identify candidate hypoxic targets of RT. To validate proteomic studies, the effect of RT on HIF-1α, miR-210, PDH-A and LDH-A levels under hypoxia was assessed by qRT-PCR. The impact of RT in hypoxia markers was evaluated in patients to confirm in vitro results. An increase in the HIF-1α levels was observed in OSCC. RT reduced OSCC cell proliferation and migration. Interestingly, hypoxia could revert the effect of radiation on OSCC phenotype. However, proteomics analyses suggested that LDH is one of the critical targets of RT even in hypoxia. Moreover, RT decreased HIF-1α, miR-210, and LDH even in hypoxia. The current study demonstrated that hypoxia could revert the effects of RT in the OSCC context. However, RT reduces the levels HIF-1α, miR-210 and LDH in vivo and in vitro. The consequences of RT in blood should be carefully investigated.
