Abstract

Epidemiological and experimental observations tend to prove that environment, lifestyle or nutritional challenges influence heart functions together with genetic factors. Furthermore, when occurring during sensitive windows of heart development, these environmental challenges can induce an ‘altered programming’ of heart development and shape the future heart disease risk. In the etiology of heart diseases driven by environmental challenges, epigenetics has been highlighted as an underlying mechanism, constituting a bridge between environment and heart health. In particular, micro-RNAs which are involved in each step of heart development and functions seem to play a crucial role in the unfavorable programming of heart diseases. This review describes the latest advances in micro-RNA research in heart diseases driven by early exposure to challenges and discusses the use of micro-RNAs as potential targets in the reversal of the pathophysiology.

Fig. 2 Micro-RNAs biogenesis. Micro-RNAs biogenesis involves different steps. Pri-micro-RNAs are transcribed from inter- and intra-genic regions. They are then processed into pre-micro-RNAs and double-stranded micro-RNAs. The mature single-stranded micro-RNAs binds to the UTR ends of targets messenger RNAs (mRNAs) to regulate their levels.
