Identification of AK4 and RHOC as potential oncogenes addicted by adult T cell leukemia.

ABSTRACT: Adult T cell leukemia (ATL) is a highly aggressive T cell malignancy characterized by human T cell leukemia virus type 1 (HTLV-1) infection. ATL has a very poor prognosis and lacks satisfactory treatments; therefore, it is critical to identify potential targets in ATL cells in order to develop effective targeted therapeutics. Here, we report the identification of two oncogenes, AK4 and RHOC, as target genes of miR-455-3p, a tumor-suppressive microRNA in ATL patients. Importantly, AK4 and RHOC are highly expressed in ATL and exhibit oncogenic potentials in vitro and in vivo. Interestingly, transcriptome and metabolome analyses reveal a functional overlap of AK4 and RHOC, including activating oncogenic pathways such as Myc targets and deregulating lipid metabolism such as enhancing the produ
