Abstract

MicroRNAs (miRNAs) are small noncoding RNAs that involved in various normal and cancer-related cellular pro-cesses. Studies on expression profiling of miRNAs have been performed and the data showed that some miRNAs are up-regulated or down-regulated in cancer. miRNAs play a crucial role in HNSCC development, metastasis, prognosis and survival rate. Several studies have been conducted previously to investigate that use of miRNAs as the biomark-ers in disease diagnostic/prognostic and potential therapeutic targets management that may improve the outcomes of HNSCC. Our previous study revealed that upregulation of oncogenic miRNAs including hsa-miR-181a-2*, hsa-miR-29b-1*, hsa-miR-181a, hsa-miR-181b, hsa-miR-744, hsa-miR-1271 and hsa-miR-221* were able to distinguish HNSCC from normal samples. These miRNAs may contribute in a simple profiling strategy to identify individuals at higher risk of developing head and neck cancers, thus helping in the elucidation of the molecular mechanisms involved in head and neck cancer pathogenesis.
