The most common Parkinson’s disease-associated mutation, LRRK2 G2019S, impairs mitophagy in clinically relevant cells within the mouse brain and this defect can be reversed using a novel LRRK2 inhibitor.
Transgenic mice and cell models provide evidence of a pathophysiological mechanism that connects mtDNA damage to cardiac dysfunction via reduced NAD+ levels and loss of mitochondrial function and communication.
Oxaliplatin-resistant colorectal cancer cells exhibit unregulated death receptor 4 expression with increased receptor palmitoylation and translocation into lipid rafts, increasing their sensitivity to apoptosis via TRAIL.
Highly conserved C-terminal domains of the tumor suppressor BRCA2 are not essential for accumulation at damaged DNA but affect conformation and cell survival, implying roles beyond delivering strand-exchange protein RAD51.
The piRNA pathway regulates satellite DNAs in the Drosophila melanogaster germline and affects heterochromatin establishment at pericentromeric satellite DNA in embryos, implying a general role for piRNAs in ensuring genome stability.
