Until recently, radiation effects have been considered to be mainly due nuclear DNA damage and their management by repair mechanisms. However, molecular biology studies reveal that the outcomes of exposures ionizing (IR) highly depend on activation regulation through other components organelles determine cell survival proliferation capacities. As typical epigenetic-regulated central power stations cells, mitochondria play an important pivotal role in those responses. They direct cellular metabolism, energy supply homeostasis as well radiation-induced signaling, death, immunological This review is focused how energy, dose quality IR affect mitochondria-dependent epigenetic functional control at tissue level.
