Mice with a mutation that disrupts the release of growth hormone show greatly increased lifespan, which can be further increased by caloric restriction.
Bacteria use the transcription factor binding region of their transcription activator-like effectors to hijack host basal transcription factor to cause rice diseases by activating host susceptibility genes.
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.
The use of tissue culture reduces the chemical modification of plant DNA, and this has lasting effects on gene expression in the plants and their descendants.
The expression of small RNAs (or sRNAs) is regulated not only by mRNA expression, but also by their own regulatory elements and by sRNA biogenesis genes.
LRRK2 G2019S knock-in mice are a genetically faithful model that recapitulates the slow disease progression of familial PD, with initial alterations to behaviour and neurotransmission providing early pathophysiological targets for neuroprotective interventions.
A new perception of the organization of T-cell receptor repertoires in mice and humans, based on high-throughput sequencing and CDR3 sequence similarity, indicates hubs of cross-species public sequences forming evolutionary conserved 'foci of attention' of T cell immunity.
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.
Specialized fungal pathogen populations infect rice varieties with contrasting immune systems co-cultivated in a traditional agro-system, indicating the relevance of crop diversity to restricting epidemics in the landscape.
