Global loss of DNA methylation is frequently observed in the genome of human tumors. Although this epigenetic alteration is clearly associated with cancer progression, the way it exerts its pro-tumoral effect remains incompletely understood. A remarkable consequence of DNA hypomethylation in tumors is the aberrant activation of "cancer-germline" genes (also known as "cancer-testis" genes), which comprise a diverse group of germline-specific genes that use DNA methylation as a primary mechanism for repression in normal somatic tissues. Here we review the evidence that such cancer-germline genes contribute to key processes of tumor development. Notably, several cancer-germline genes were found to stimulate oncogenic pathways involved in cell proliferation (SSX, DDX43, MAEL, PIWIL1), angiogenesis (DDX53), immortality (BORIS/CTCFL), and metastasis (CT-GABRA3). Others appear to inhibit tumor suppressor pathways, including those controlling growth inhibition signals (MAGEA11, MAGEB2), apoptosis (MAGEA2, MAGEC2), and genome integrity (HORMAD1, NXF2). Cancer-germline genes were also implicated in the regulation of tumor metabolism (MAGEA3/MAGEA6). Together, our survey substantiates the concept that DNA hypomethylation promotes tumorigenesis via transcriptional activation of oncogenes. Importantly, considering their highly restricted pattern of expression, cancer-germline genes may represent valuable targets for the development of anti-cancer therapies with limited side effects.
