The accumulation of somatic mutations during aging is not uniform across tissue types and, in addition, shows significant variability in the source of mutation that can be modified by small molecule interventions.
Modulation of histone levels in gut enterocytes by rapamycin treatment alters chromatin organisation and induces intestinal autophagy through transcriptional regulation to prevent age-related decline in the intestine and extend lifespan.

Biologically plausible levels of myelin dystrophy induce substantial working memory impairment in a computational model of brain aging across two spatial and temporal scales.

Short-term treatment with rapamycin reverses periodontal bone loss, attenuates inflammation, and remodels the oral microbiome toward a more youthful state.
Rat blood profiles support non-linear aging with distinct trajectory shifts, and these profiles could be used to predict non-overt illness in rats or aging intervention efficacy.
By controlling the SUMOylation of the protein CAR-1, the aging-regulating pathways downstream of the Insulin/IGF signaling cascade and of the germ cells of the nematode Caenorhabditis elegans are integrated.
