Furthermore, miR-71 plays a prominent role in developmental recovery from L1 diapause partly through repressing the expression of certain heterochronic genes. 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. But offering people opportunities to explore games and play in a safe, non-abusive, self-directed context like a library seems to me to matter, and for folks who are more likely than most to have social anxieties, finding those opportunities can be extremely hard. This certainly accords with the rise of therapists using games as therapy – a web search for “Dungeons & Dragons therapy” shows the recent explosion in ways in which people are finding healing in play. That means that when sales are up, more people are playing this and other older, less-fun games instead of games with the advantage of more than a century’s advancements in the art and science of play, including co-operative games, social games, nomic games, and more.

Non-Unc stable transgenic lines were maintained, and the expression of GFP and mCherry were observed under a Zeiss Axiovision II microscope. Three days later, the number of worms that were L2 or older was recorded as number of survived worms (Ns), and the survival rate was calculated as Ns/Np, which is an estimation of survived worms in the whole population. MT12993 mir-71(n4115) worms were outcrossed with N2 for four generations before any test except the initial screen. A recent study showed that the expression of miR-71 was significantly increased relative to other miRNAs in starved L1 worms (15). However, miR-71 does not appear to regulate all postembryonic development during L1 diapause recovery. Unlike classical heterochronic miRNAs such as lin-4 and let-7, the role of miR-71 in vulval cell division is essential in animals recovering from starvation-induced L1 diapause, but not in animals hatched on plates with food.

It is also worth mentioning that multiple components of the InsR pathway, including age-1, pdk-1, akt-2, and daf-16, are predicted to be targets of the let-7 family miRNAs. On one hand, we showed that deletions of a good number of miRNAs have varying impacts on the L1 diapause survival rate, although they may effect the rate through different mechanisms. Instead, many specific physiological functions, such as the starvation-induced stress response, are regulated by a miRNA-target network, often involving multiple miRNAs and a large number of their targets. This is consistent with hbl-1 being one of the downstream targets of miR-71, although this modest effect alone is not expected to account for the vulval developmental phenotype in mir-71 mutant. 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).

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). In worms that recovered from 4 d of L1 starvation, we also found that a significant portion of the mir-71(lf) mutants displayed egg-laying defects and overproliferating or precociously reflexed gonads. (A) The mir-71(n4115, lf) mutant displayed severe reduction in L1 starvation survival rate, and the reduced survival rate of mir-71(lf) was suppressed by a reduction-of-function allele of age-1(hx546). To investigate the roles of miRNAs in animal survival during starvation-induced L1 diapause, we impaired the overall miRISC function with loss-of-function (lf) mutants of ain-1 (ku322, ku425, and tm3681) and ain-2(tm2432) and examined their L1 starvation survival rate (Materials and Methods). To test the hypothesis that these developmental timing genes mediate the regulatory role of miR-71 in larval development during recovery from starvation-induced L1 diapause, we examined whether knocking down HBL-1 function can suppress the retarded VPC timing defect of mir-71(lf). Note that the daf-16(lf) worms recovering from 3 d of L1 starvation displayed a ∼12-h delay in overall development and that the mir-71(lf); daf-16(lf) double mutants displayed an ∼24-h delay.

I recommend turning it off to see how it impacts this specific image. In normally exposed images, this method can lead to oversaturation, so I usually reduce it using other modules like Color Balance RGB. The LAB tone curve is mostly me experimenting to see how it affects color saturation, particularly in the Blue and Magenta spectrum, which I often adjust.

These benefits are especially important for people dealing with a health condition that may make them feel isolated. These lived experiences can offer meaningful insight, showing that recovery is possible even when it feels far away. Support groups are guided by experienced clinicians and often include people who have been through similar challenges. This kind of open environment helps reduce feelings of shame and encourages honest conversations. They offer a space where people can talk about what they’re going through without fear of judgement.

The coordinated entrance into developmental arrest, long-term survival, and the reinitiation of development upon food availability are important biological processes to investigate. Different organisms have developed versatile growth arrest strategies to overcome starvation-induced metabolic and developmental problems. Food deprivation is a life-threatening challenge that animals frequently face as individuals and as species. Numerous animal species across multiple phyla enter developmental arrest for long-term survival in unfavorable environments and resume development upon stress removal.

L1 Starvation Survival Assay and Statistical Analysis.
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).
The overall effect of miRNAs on L1 starvation survival is expected to be significantly stronger than that reflected by the data in Fig. These results suggest that miRNAs act in the intestine, and possibly in other tissues, to promote L1 starvation survival. However, the mechanisms that coordinate the long-term survival, overall developmental arrest, and reinitiation remain to be investigated.
Waking up not knowing what you did last night and that when we promise we’ll never drink again, it’s quite fine when we reach for the wine and wine glass the next weekend when happy hour hits. And for those of us who have taken a step into the other side, regardless of sobriety time, see it. A mechanism through which we can move through our addiction and keep saying YES to an AF life.
Laura explains that you are to imagine a scenario where you would anticipate feeling that without alcohol/drinking, it would be incomplete, not fun, boring etc. She writes about a practice she learned in therapy, a form of written visualization, where you play two different tapes forward (hmm… I thought there was only one…). A life of freedom and rid of the toxicity that drives us further and further away from who we really are. What playing the tape forward does is remind me.
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. We detected that you have an open account recovery request. Penalties are applied no matter who was playing at the time.

Components of the InsR pathway, including age-1, have recently been predicted to be targets of miR-71 in its role in aging (14). On the other hand, the role of a particular miRNA (miR-71) is executed by repressing the expression of many genes in multiple pathways. These results compelled us to examine specific interactions between individual miRNAs and their targets to gain mechanistic insights. This result is also consistent with the prediction from a miRISC immunoprecipitation analysis that hbl-1 is likely a target of one or more miRNAs, in addition to the let-7 family miRNAs, during early development (18). This result suggests that miR-71 likely functions upstream of, or in parallel to, HBL-1 in regulating VPC timing.
