Therapeutic potential of the human endogenous retroviral envelope protein HEMO: a pan-cancer analysis.

ABSTRACT: Human endogenous retroviruses represent approximately 8% of our genome. Most of these sequences are defective except for a few genes such as the ancestral retroviral HEMO envelope gene (Human Endogenous MER34 ORF), recently characterized by our group. In this study, we characterized transcriptional activation of HEMO in primary tumors from The Cancer Genome Atlas (TCGA) and in metastatic tumors from a Gustave Roussy cohort. Pan-cancer detection of the HEMO protein in a series of patient samples validated these results. Differential gene expression analysis in various TCGA datasets revealed a link between HEMO expression and activation of Wnt/β-catenin signaling, in particular in endometrial cancer. Studies on cell models led us to propose that the Wnt/β-catenin pathway could act as an upst
