Using genetically engineered mouse models of cutaneous carcinogenesis to characterize oncogene-driven cancer immunoediting
Cancer develops as the end product of a multistep process in which cells and/or their microenvironments accumulate alterations, either genetic or epigenetic, which enable uncontrolled growth. During the early steps of this process, altered cells constituting the precursors to cancer are subject to the constraints of natural selection. As such, variations within the population of transformed cells which lead to increased relative fitness are reproductively favored by the various selective pressures of the local microenvironment. Anti-tumor immunity is an important arm of this pre-malignant ...
