Membrane potential recordings in awake mice from two genetically defined classes of neocortical inhibitory neurons reveal their distinct patterns of activity and unitary excitatory synaptic inputs, which are differentially modulated by behavior and local network activity.
Three months treatment with the drug rapamycin increases lifespan, alters cancer prevalence, remodels the microbiome, and improves functional measures of health in middle aged mice in a dose- and sex-dependent manner.
Mirroring human patients with ARID1B mutations, Arid1b haploinsufficient mice exhibited numerous neuropsychiatric defects and revealed IGF1 deficiency related growth impairment that could be ameliorated with growth hormone supplementation.
Social-interaction impairment in germ-free mice is associated with a markedly altered transcriptional response to social novelty in the amygdala, as characterised by replacement of upregulation of common stimulus-induced pathways with upregulation of the splicing machinery.
The dramatic extension of lifespan in Sirt6-deficient mice by Trp53 haploinsufficiency suggests that SIRT6 has distinct biological function from SIRT1 in regulating p53 activity and preventing cells from senescence/apoptosis.
