MiR-71 regulates vulval cell division during recovery of starved L1 worms. We thus asked whether miR-71 was required for the reinitiation of developmental programs during the recovery phase after L1 starvation. These results indicate that miR-71 is not essential for arresting seam cell or M-cell divisions during L1 diapause, suggesting that miR-71 function is distinct from DAF-16 function. DAF-16 (the FOXO homolog in C. elegans) has been shown to play an important role in cell cycle arrest and developmental progression partly by promoting cki-1 expression in some somatic cells during L1 arrest (2). S1A indicated a dominant role of intestinal miRNAs in regulating L1 starvation survival.

Support groups can be a place to feel heard, supported, and gently accompanied as you take steps forward. At Khiron Clinics, we see support groups as one strand in a wider web of care. For many, they are the first place where isolation begins to soften and hope feels possible again. These sessions complement individual therapy and help create a sense of containment, safety, and continuity.

Which leads me to add to my wholehearted endorsement of Gene’s call for libraries to make allowances for people to avoid play and games. The fact that family game night might, as Gene remarked, be a source of trauma is primarily an indictment of the state of those families – but given play’s links to health and the fact that games can heal and promote bonding and caring, it seems unwise to ignore the qualities of the games they are playing. It’s easy to take this as a joke – families fight over board games, oh well, It’s Only A Game – but if you dig even slightly into this, you find that some of these experiences are genuinely traumatic, as one would expect might be necessary to give someone a lifelong aversion to an entire medium. Monopoly is… as legendary for spawning bitter family fights and for dragging on interminably even though it’s obvious who’s going to win as it is for being widely played.

- However, the mechanisms that coordinate the long-term survival, overall developmental arrest, and reinitiation remain to be investigated.
- 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).

(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). We found that the 3′UTRs of several genes of the InsR pathway, including unc-31, age-1, pdk-1, akt-2, and sgk-1, contain predicted miR-71 targeting sites (as predicted by TargetScan and mirWIP). (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).
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.
By working toward these goals in a group setting, clients are able to track progress while receiving therapeutic input from trained clinicians. These sessions are not peer-led support groups, but professionally facilitated therapeutic spaces grounded in trauma-informed care. Our approach is not about peer discussion, but about structured healing guided by professionals involved in the recovery process.
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.

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.
(H) Fluorescence and DIC images showing that a lin-42 3′UTR reporter was repressed in mir-71(+) worms (2/2 transgenic lines) and prominently derepressed in mir-71(−) worms (2/2 transgenic lines). The numbers on each image indicate how many worms of the examined ones displayed the indicated phenotype. These results suggest that miR-71 regulates the expression of unc-31 and age-1 through their 3′UTRs. Note that there are extra GFP-positive cells (red arrows) in mir-71(lf) mutants.

(C) The reduced L1 starvation survival rate of ain-1(lf) mutants was significantly suppressed by a null allele of unc-31. Compromising overall miRNA function dramatically reduces the survival rate of L1 worms in starvation-induced diapause, and the effect can be significantly suppressed by an age-1/PI3K mutation. Our genetic analysis indicated that for both L1 diapause survival and developmental recovery functions, miR-71 regulates expressions of genes in both the insulin receptor-dependent and -independent pathways. (F) Fluorescence and DIC images showing that an hbl-1 3′UTR reporter was repressed in mir-71(+) worms and slightly derepressed in mir-71(lf) mutants. (E) DIC images showing that hbl-1(RNAi) caused precocious VPC divisions in late L2/early L3 in both wild-type and mir-71(lf) worms recovered from 4 d of L1 starvation. (C) Bar graph showing that the delayed VPC timing defects of mir-71(lf) worms was suppressed by an unc-31(lf) mutation and partially suppressed by an age-1(rf) mutation.
