AKT1 and lip and oral cavity carcinoma: Shi et al., studied the activation and ubiquitination of AKT in high TRAF6 expression cells such as oral cancer cell HN12 and breast cancer cell MDA-M-231 and low TRAF6 expression cells including oral cancer cell SCC9 and breast cancer cell MCF-7, their findings showed high ubiquitination and activation of AKT were observed in cells with highly expression of TRAF6, compared with low TRAF6 expression cells.
