ParpCH1 heterozygous mutant adults do not present altered oxygen consumption and do not present brain mitochondria with altered potential, as compared to controls.
ParpCH1/+ mutants display no reduction in dopaminergic PPL1 neuron number as compared to controls.
The average size of the heat shock puffs at 87A and 87C on the polytene chromosomes is reduced threefold in mutant larvae compared to wild type. Mutant larvae often develop intracellular bacterial infections, which is rarely seen in wild type. The larvae are also sensitive to experimental infection; 95% die after a dose of injected E.coli that kills less than 7% of controls.
Homozygotes develop slowly and usually die during the second instar stage after 6-9 days. The brain is of normal size. Up to 50% of the larvae are arrested at the onset of ecdysis II (as seen by the phenotype of the mouth hooks). Nuclear morphology is dramatically altered in mutants; the nuclei appear more uniform than wild type, have a less distinct chromocenter and lack a nucleolar region of low DNA density.

ParpCH1 heterozygosity leads to a significant suppression of the defects in lifespan, climbing capacity, thorax morphology, number of dopaminergic PPL1 neurons, mitochondria cristae morphology in the neuropil and oxygen consumption, observed in Pink1B9 homozygous mutant adults; ParpCH1 also rescues the decreased mitochodria potential observed in the brains of Pink1B9 homozygous mutant adults.
