TranscriptomicsA High-Fat Diet and NAD+ Rescue Premature Aging in Cockayne Syndrome
Cockayne syndrome (CS) is an accelerated aging disorder characterized by progressive neurodegeneration caused by mutations in the genes encoding the DNA repair proteins CSA or CSB. Csbm/m mice were given a high-fat, caloric-restricted or resveratrol-supplemented diet. The high-fat diet rescued the p...

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...

TranscriptomicsSRT2104 extends survival of male mice on a standard diet and preserves bone and muscle mass
Increased expression of SIRT1 extends the lifespan of lower organisms and delays the onset of age-related diseases in mammals. Here, we show that SRT2104, a synthetic small molecule activator of SIRT1, extends both mean and maximal lifespan of mice fed a standard diet. This is accompanied by improve...

TranscriptomicsEffects of Sex, Strain, and Energy Intake on Hallmarks of Aging in Mice
Calorie restriction (CR) is the most robust non-genetic intervention to universally delay the onset of age-related diseases and extend mean and maximum lifespan. However, species, strain, sex, diet, age of onset, and level of CR are emerging as important variables to consider for a successful CR res...
