ProteomicsMitochondria preconditioning delays aging and associated diseases in C. elegans impacting on key ferroptosis players
Excessive iron accumulation or deficiency have detrimental consequences across species, leading to a variety of pathologies in humans. In the nematode Caenorhabditis elegans severe iron as well as oxygen deprivation induce developmental arrest. Instead, hypoxia preconditioning protects against sever...

TranscriptomicsLoss of Caenorhabditis elegans UNG-1 uracil-DNA glycosylase affects apoptosis in response to DNA damaging agents.
The nematode Caenorhabditis elegans has been used extensively to study responses to DNA damage. In contrast, little is known about DNA repair in this organism. C. elegans is unusual in that it encodes few DNA glycosylases and the uracil-DNA glycosylase (UDG) encoded by the ung-1 gene is the only kno...

TranscriptomicsDefective Mitophagy in XPA via PARP1 activation and NAD+/SIRT1-depletion: Implications for neurodegeneration (mouse)
Mitochondrial dysfunction is a common feature in neurodegeneration and aging. We identify mitochondrial dysfunction in xeroderma pigmentosum group A (XPA), a nucleotide excision DNA repair disorder with severe neurodegeneration, in silico and in vivo. XPA deficient cells show defective mitophagy wit...

TranscriptomicsExpression changes in Caenorhabditis elegans xpa-1 mutant
Background: The ability of an organism to repair DNA damage is implicated in carcinogenesis and aging. Interestingly expression profiling of Nucleotide Excision Repair (NER) deficient segmental progeroid mice revealed gene expression changes resembling these observed in aged wild type animals. Our p...
