Outline of Final Research Achievements

We have shown previous that the small-GTPase Arf6 and its downstream signaling factors are frequently overexpressed in different cancers and execute a cancer mesenchymal program, including invasion, metastasis and drug resistance. Here, we show a molecular basis by which Arf6 protein becomes overexpressed in some cancer cells. Our results indicated that an oncogenic mutation of a certain gene evokes an enhanced activity of eIF4A, which promotes translation of the Arf6 mRNA; and thus established an causative role of the enhanced mRNA translation in cancer malignancy development.
