Epigenetic Priming in Cancer Initiation

Trends Cancer. 2018 Jun;4(6):408-417. doi: 10.1016/j.trecan.2018.04.007.

Abstract

Recent evidence from hematopoietic and epithelial tumors revealed that the contribution of oncogenes to cancer development is mediated mainly through epigenetic priming of cancer-initiating cells, suggesting that genetic lesions that initiate the cancer process might be dispensable for the posterior tumor progression and maintenance. Epigenetic priming may remain latent until it is later triggered by endogenous or environmental stimuli. This Opinion article addresses the impact of epigenetic priming in cancer development and in the design of new therapeutic approaches.

Keywords: cancer; cancer stem cell; cancer therapy; oncogenes; reprogramming; stem cells.
