View SamplesMicroRNAs (miRNAs) regulate target mRNAs through a combination of translational repression and mRNA destabilization, with mRNA destabilization dominating at steady state in the few contexts examined globally. Here, we extend the global steady-state measurements to many additional mammalian contexts and find that regardless of the miRNA, cell type, growth condition or translational state, mRNA destabilization explains most (70% to >90%) miRNA-mediated repression. We also determine the relative dynamics of translational repression and mRNA destabilization for endogenous mRNAs as a miRNA is induced. Although translational repression occurs rapidly, its effect on gene expression is relatively weak, such that by the time consequential repression ensues, the effect of mRNA destabilization dominates. These results add to the fundamental understanding of miRNAs, imply that consequential miRNA-mediated repression is largely irreversible and simplify future studies, dramatically extending the known contexts and time points for which monitoring mRNA changes captures most of the direct miRNA effects.

View SamplesTo ask whether MANF contributes to the rejuvenating effects of heterochronic parabiosis, we generated heterochronic pairs in which 20 month old WT mice were combined with either 4 month old MANFHet (O-YgHet) or WT (O-YgWT) littermates, and maintained for 5 weeks before analysis. Control pairs in which old WT mice were combined together (O-O) were used. Livers were collected from each animal in the pair and RNA was sequenced for 5 independent animals/condition. Overall design: RNA was extracted and sequenced for 5 animals/condition
MANF regulates metabolic and immune homeostasis in ageing and protects against liver damage.

View SamplesIn the nervous system, neural stem cells (NSC) are necessary for the generation of new neurons and for cognitive function. Here we show that FoxO3, a member of a transcription factor family known to extend lifespan in invertebrates, regulates the NSC pool. We find that adult FoxO3-/- mice have fewer NSC in vivo than wild type counterparts. NSC isolated from adult FoxO3-/- mice have decreased self-renewal and an impaired ability to generate different neural lineages. Identification of the FoxO3-dependent gene expression profile in NSC suggests that FoxO3 regulates the NSC pool by inducing a program of genes that preserves quiescence, prevents premature differentiation, and controls oxygen metabolism. The ability of FoxO3 to prevent the premature depletion of NSC might have important implications for counteracting brain aging in long-lived species.
