Mitochondrial Oncometabolites and mTORC1 Dominant mutations in mitochondrial enzymes led to identification of mitochondrial derived signaling molecules, called oncometabolites

Overall, these genetic defects result in disrupted energy metabolism and defective mitochondrial signaling pathways

this may be because NMN first requires dephosphorylation into NR before uptake into cells 39
