Abstract

As one of the subtypes of head and neck cancer (PBC), the oral squamous cell carcinoma, is the head and neck cancer more common and is strongly associated with use of tobacco and alcohol. The multifunctional protein SET is an oncoprotein involved in the regulation of apoptosis, transcription, besides being a subunit complex that inhibits histone acetylation by binding to and masking histone acetyltransferase targets of keeping the target DNA in its form hipoacetylated and, therefore contributing to the maintenance of DNA and genes silenced. However, potential targets of SET, regulatory RNAs (miRNAs) and processes such as apoptosis and cell migration have not been thoroughly checked. Our goal is to obtain quantitative and qualitative information regarding the expression of RNAs, miRNAs and proteins using model in vitro and in vivo (xenograft and transgenic animal for SET) regulated by SET protein in normal and tumor cells.
