Experiments in mice with matching nuclear DNA but different mitochondrial DNA linked aging to changes in retinal energy-producing proteins and immune signalling.Experiments in mice with matching nuclear DNA but different mitochondrial DNA linked aging to changes in retinal energy-producing proteins and immune signalling.
Experiments in male and female mice with differing mtDNA, against mice with C57 mtDNAMitochondrion
Limit: The mtDNA damage result lost significance when a potential outlier was excluded
Animal experiments found that loss of an immune-signalling protein harmed early bone development but protected against age-related bone loss from middle age onward.Animal experiments found that loss of an immune-signalling protein harmed early bone development but protected against age-related bone loss from middle age onward.
Experiments in male mice, against age-matched WT miceImmune response
Limit: Bone-mass differences supporting the age-dependent reversal were not statistically significant

In mouse midbrain and cultured human neurons, alpha-synuclein pathology led to shorter, more saturated lipid chains, an effect largely reversed in mice by intermittent…In mouse midbrain and cultured human neurons, alpha-synuclein pathology led to shorter, more saturated lipid chains, an effect largely reversed in mice by intermittent fasting.
In aged mice, lacking Sestrin1 worsened liver cell senescence and fat buildup, and the protein proved indispensable for the liver benefits of exercise.In aged mice, lacking Sestrin1 worsened liver cell senescence and fat buildup, and the protein proved indispensable for the liver benefits of exercise.
