Knocking down lit-1 by RNAi in mir-71(lf); lin-42(lf) double mutants caused no significant suppression of the VPC timing defects of mir-71(lf) worms. To determine the functional relationship of miR-71 with LIN-42 and LIT-1, mir-71(lf); lin-42(lf) L1 worms were starved for 4 d and recovered on lit-1(RNAi) plates. The strong suppression of the mir-71(lf) defect by hbl-1(RNAi), and the relatively weak effect of miR-71 on hbl-1 expression, are consistent with the idea that miR-71 exerts its role by modulating activities of multiple genes related to hbl-1 function in developmental timing. We then compared the expression of a hbl-1 3′UTR reporter (18) in the mir-71(lf) mutants with that in wild type and found that the expression of this reporter was slightly derepressed at L3 in the mir-71 mutant (Fig. 4 F and G).

This result suggests that the high expression of miR-71 during L1 diapause is induced or maintained by other signaling pathways. We asked whether the expression of miR-71 was regulated by DAF-16, which is required during L1 diapause for long-term survival (2). It is possible that other miRNAs, including those in the let-7 family, control developmental timing in other tissues during the recovery phase after L1 starvation. We speculate that the expression of heterochronic genes controlling the L2/L3 programs, including that of hbl-1 and lin-42, are increased during L1 diapause to arrest the developmental progression, and miR-71 is probably required to suppress these “excess” signals during the recovery phase (Fig. S5). As pointed out above, multiple miRNAs in addition to miR-71 and the let-7 family miRNAs have roles in L1 diapause, and they may regulate the expression of many diverse targets that may include, but are not limited to, factors involved in UNC-31–InsR-signaling activities. Although the complete removal of miRNA functions causes embryonic lethality or infertility in worms, a partial disruption of overall miRNA functions by mutating either ain-1 or ain-2 provides an effective way to investigate miRNA functions (16, 17).

Given my views on play, you won’t be surprised to learn that I asked the presenters about whether play experiences could qualify as the kinds of responsive, positive, engaged, and empowering interactions they described. I was attending professional development aimed at helping library staff support families from refugee backgrounds, and we were discussing the role that libraries and childcare staff (mostly the latter, based on the mix of the group) can play in helping often highly traumatised communities. A small increase in risk of harm, replicated many times on a massive scale, means harm is certainly occurring. As COVID-19 lockdowns unfolded around the world, and sales of games, puzzles, toys, and other playful artforms spiked, a friend asked me if I felt a sense of validation. And worst of all, a combination of the two, where other players essentially become supporting cast for a scripted victory that is neither earned, nor fun, nor remotely playful – a psychodrama rather than a game, toying with their victims rather than playing with them. Controlling bullies who insist everyone play their way, forcing people to make deals they don’t want and to keep playing even when they aren’t having fun.

However, we found that the reporter transgene with the lin-42 3′UTR was significantly repressed in wild-type worms, but derepressed in the mir-71(lf) worms (Fig. 4 H and I). In starved L1 worms, we detected only a slight increase in the mRNA level of hbl-1 in mir-71 mutants compared with that in wild type (∼10%), which may not be biologically significant. These results indicate that miR-71 plays a significant role in larval development of animals recovering from L1 diapause and likely does so by regulating the expression of components of the insulin receptor/DAF-16 pathway, as well as factors acting downstream, or in parallel to, DAF-16. If this were true, the starved mir-71(lf); daf-16(lf) double-mutant worms should show a slow growth phenotype similar to that of daf-16(lf) worms, but no specific VPC timing defect.

  • Community support is stronger when everyone involved is informed and connected.
  • Reduction-of-function mutation (rf) in the age-1/PI3 kinase gene, age-1(hx546), made worms long-lived in the L1 starvation assay and was able to suppress the reduced L1 survival rate of mir-71(lf); the rate of the double mutants was comparable to that of wild type (Fig. 2A).
  • The roles of InsRs have also been implicated in arresting the cell cycle in germ cells and a portion of somatic cells during L1 diapause (2, 4).
  • At festivals, the group shared the stage with acts like Casper, Distance in Embrace, and Rantanplan.
  • Rather, we should be – you guessed it – intelligently curating and sharing the more pro-social alternatives, and giving people context and vocabulary for their engagement with culture.
  • (B) The severely reduced survival rate of the mir-71(lf) mutant was suppressed by a null allele of unc-31(e928).

  • He’s far from the only one who has a negative reaction to play as a result of traumatic associations.
  • And as we’ve discussed above, simply offering the kind of safe, supported opportunities to play that we’d want to offer anyway is enough to create that space for healing.
  • To identify individual miRNAs that play prominent roles in L1 diapause, we screened 72 available mutant strains of individual miRNAs and miRNA families (87 miRNAs in total) using the L1 starvation assay.
  • The effect observed in ain-1(lf) mutants is likely the consequence of the combined effects of attenuating functions of these individual miRNAs.
  • Moreover, the expression of hbl-1 is repressed by let-7 family miRNAs at L3 during normal development, and the hyperactivity of hbl-1 caused by failure of miRNA regulation leads to retarded development (26).
  • What playing the tape forward does is remind me.

The PlayStation Family app lets you manage your family from your mobile device, and offers additional options to monitor your children’s playtime. Understanding the role support groups play in mental health crisis recovery is essential for individuals, families, and professionals seeking effective support during difficult times. Education should be pursued in every area of life, including addiction, recovery, and how family support is intertwined in it. Furthermore, the observed derepression of individual genes by mir-71(lf) seemed too weak to account for the phenotype, consistent with the idea that a prominent phenotype of an miRNA mutation is caused by the collective effect of changing expression in many genes, an important property of miRNA-mediated gene regulation.

It’s also notorious among tabletop enthusiasts for making some people loathe the entire medium of board games… I’ve got several posts to write on this topic, but I want to start by honouring Gene’s remarks with a ringing endorsement of his point about supporting those with trauma responses to play, and building on what that means more broadly. I’d like to thank whoever chose the GLAM Blog Club theme for this month, and highlight some of my past posts as potential inspiration for anyone thinking of writing about play and games in a libraries/GLAM context – specifically my Talking Points series, especially the second one, on the powers of play.

miR-71 Likely Directly Represses the Expression of age-1 and unc-31 by Acting on Their 3′ Untranslated Regions.

Furthermore, worms that are long-lived due to dietary restriction or decreased mitochondrial respiratory rates are short-lived during L1 diapause, suggesting that the mechanisms controlling L1 starvation survival are different at least in some aspects from those controlling aging (3). We provide evidence that miRNA miR-71 is not required for the animals’ entry into L1 diapause, but plays a critical role in long-term survival by repressing the expression of insulin receptor/PI3K pathway genes and genes acting downstream or in parallel to the pathway. We need to be promoting better-quality games that do more to help people have fun, and we need to be modelling and making room for healthy play that promotes pro-social behaviour. That means running programs, preferably having staff who can teach the games, having services that help people find others who can teach and/or are interested in playing, and establishing norms for play in the library space in the hopes of (a) offering that safe, and potentially healing, interaction; (b) having those norms spread.
