Interaction Information:

Comment The structure of degenerating MNs (motor neurons) in G93A-mSOD1 mice does not resemble apoptosis but rather slow necrosis. It is characterized by somal and mitochondrial swelling and formation of DNA single-strand breaks prior to double-strand breaks occurring in nuclear and mitochondrial DNA.
