DNA damage repaired by antioxidant enzymes

The human nucleus is metabolically active, according to the findings of a new study in Molecular Systems Biology by researchers at the CRG in Barcelona and CeMM/Medical University of Vienna, In a state of crisis, such as widespread DNA damage, the nucleus protects itself by appropriates mitochondrial machinery to carry out urgent repairs that threaten the genome’s integrity The findings represent a paradigm shift because the nucleus has been historically considered to be metabolically inert, importing all its needs through supply chains in the cytoplasm Cancer hijacks cellular metabolism for unfettered growth. The findings can help guide future lines of cancer research by offering new clues to overcome drug resistance and eventually the design of new treatments
