Mutating miR-71 drastically reduces the survival rate of animals in L1 diapause, and the effect can be suppressed by mutations of insulin receptor pathway genes age-1 and unc-31. Among short-lived miRNA mutants, a mir-71 deletion mutant, mir-71(n4115) (referred to as mir-71(lf) hereafter), displayed a severe reduction in L1 starvation survival rate (Table S1 and Fig. 2A). We found that the reduced survival rate of ain-1 was suppressed by either reduction of age-1 function or loss of unc-31 function (Fig. 1 B and C), suggesting that a significant portion of the overall miRNA functions in L1 diapause is upstream of, or in parallel to, the InsR pathway. In this study, we addressed the questions of whether and how miRNAs impact developmental arrest and the long-term survival of early L1 stage worms in response to food starvation. Here we show that compromising overall microRNA (miRNA) functions or mutating certain individual miRNAs impairs the long-term survival of nematodes during starvation-induced L1 diapause. Third-party accounts will also be restored if third-party backup was enabled on the old device.
Member States can also amend their plan if they can demonstrate that objective circumstances render the implementation of certain milestones and targets unfeasible. The RRF is also crucial for implementing the REPowerEU plan – the Commission’s response to the socio-economic hardships and global energy market disruption caused by Russia’s invasion of Ukraine. Through the Facility, the Commission raises funds by borrowing on the capital markets (issuing bonds on behalf of the EU).

(D) Bar graph showing that the delayed VPC timing defect of mir-71(lf) worms was enhanced by daf-16(lf) after 1 or 3 d of L1 starvation. (B) Bar graph showing the correlation between the severity of the retarded vulval precursor cell (VPC) timing defect of mir-71(lf) mutants and the duration of L1 starvation. Whereas the vulva of wild-type worms developed into the pyramidal stage (81 of 82 worms), the P6.p of mir-71(n4115, lf) mutant worms divided only once (83 of 89 worms). The computation-based prediction that age-1 and pdk-1 are potential targets of miR-71 was also reported in a recent study focusing on miRNA functions in aging where the mRNA level of pdk-1 was shown to be up-regulated in mir-71 worms (14). (C) Fluorescence and differential interference contrast (DIC) images showing that the age-1 3′UTR reporter was repressed in mir-71(+) worms (3/4 transgenic lines) but not in mir-71(lf) worms (4/4 transgenic lines).
