Glycerol 3-phosphate acyltransferase exacerbates α-synuclein-induced toxicity by increasing lipid peroxidation

2 months 4 weeks ago
Although multiple cellular pathways have been implicated in α-Synuclein (α-syn)-associated Parkinson's disease (PD), the role of lipid metabolism remains elusive. In this study, we identify Drosophila mino, which encodes the mitochondrial isoform of the lipid synthesis enzyme glycerol 3-phosphate acyltransferase (GPAT), as a potent modifier of α-syn. Silencing the expression of mino significantly suppresses α-syn-induced PD phenotypes in Drosophila, including dopaminergic neuronal loss and...

C1q-dependent clearance of alpha-synuclein allows macrophages to transiently limit enteric synucleinopathy in male mice

2 months 4 weeks ago
Deposition of misfolded α-synuclein (αsyn) in the enteric nervous system (ENS) is found in multiple neurodegenerative diseases. It is hypothesized that ENS synucleinopathy contributes to both the pathogenesis and non-motor morbidity in Parkinson's Disease (PD), but the cellular and molecular mechanisms that shape enteric histopathology and dysfunction are poorly understood. Here, we employ a fibrillar injection model of enteric synucleinopathy in male mice and demonstrate that ENS-resident...

Integrative epigenetics and transcriptomics identify aging genes in human blood

2 months 4 weeks ago
Recent epigenome-wide studies have identified a large number of genomic regions that consistently exhibit changes in their methylation status with aging across diverse populations, but the functional consequences of these changes are largely unknown. On the other hand, transcriptomic changes are more easily interpreted than epigenetic alterations, but previously identified age-related gene expression changes have shown limited replicability across populations. Here, we develop an approach that...
