Much early work on environmental stress, including ionizing radiation and environmental toxins, emphasised their action on DNA and subsequent mutagenesis in long term effects including germ cell mutagenesis, carcinogenesis and trans-generational effect. However, recent studies are increasingly pointing a complementary role of epigenetic effects in these processes. While a substantial part of the literature focuses on DNA methylation, there is increasing recognition of the role of non-coding RNAs, including small-, micro-, and pi-RNAs, as well as transposable elements. These play key roles in carcinogenesis, and in germ cell changes including trans-generational effects.
