miR-71 Is Not Required for Arresting Seam Cell or M-Cell Divisions During L1 Diapause.
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.
Everyone Can Play A Part In The Recovery Journey
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.
The reporter is strongly expressed in H and V cells in both wild-type and mir-71(lf) worms. Because miRNA-mediated gene silencing may cause translational inhibition or mRNA degradation or both (19), the relatively small increase of UNC-31 in mir-71(lf) animals was still consistent with unc-31 being a target of miR-71. To test whether the activity of the InsR pathway was down-regulated by miR-71, we first examined the endogenous expression of components of the InsR pathway in mir-71(lf). (C) The poor survival rate of daf-16(mu86, null) was enhanced by mir-71(lf).
What are the common family roles in addiction recovery?
- By Johanna C, 3 months sober (at the time of writing), most recent sober date August 18th, 2023.
- Non-Unc stable transgenic lines were maintained, and the expression of GFP and mCherry were observed under a Zeiss Axiovision II microscope.
- If someone you know has struggled with alcohol and drug addiction, we want to support you in your recovery journey today.
- We further examined the functional relationship between miR-71 and DAF-16, a FOXO transcription factor acting critically and negatively downstream of AGE-1/PI3K in the InsR pathway.
- 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.
Wild-type strains A and B are an N2 strain recently obtained from the C. (A) Survival rate curves of wild-type and mutant strains, as indicated. This is consistent with the previous reports that AIN-1 and AIN-2 are functional homologs with overlapping biochemical roles (16, 17). AIN-1 and AIN-2 are GW182 family proteins that are essential and partially redundant components of miRNA-induced silencing complexes (miRISCs) in C. MicroRNAs (miRNAs) are well known for their functions in controlling developmental timing in the nematode (5, 6). 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).

Elegans Genetic Center for many mutants of miRNA and other genes. Images were pseudocolored in Photoshop CS3 (Adobe) and assembled in Illustrator CS3 (Adobe). The data for 3′UTR expression and for VPC timing were analyzed using χ2 test. To determine viability, 20-μL aliquots (60–100 worms) were placed every 3 d onto two 6-cm nematode growth medium (NGM) plates seeded with OP50, and the numbers of L1 worms were recorded as number of plated worms (Np). A total of 16–24 h later, the density of newly hatched L1 worms was adjusted to three to five worms per microliter S-basal. The eggs were transferred to plates seeded with HB101 and bleached again 3 d later.
At festivals, the group shared the stage with acts like Casper, Distance in Embrace, and Rantanplan. The band was a support act for groups like Bakkushan, Callejon, Ohrbooten, We Butter the Bread with Butter, and Neaera. The band’s debut EP, Eskimo Callboy, was self-released in 2010 and was distributed via EMP. She has been reinventing her recovery since having children. A young people’s AA group in So CA allowed her to meet some great young people, and they partied without the alcohol. Her life became different when she let others help her and did what they said.
(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.
Briefly, worms were well fed for at least two generations, and gravid adults were bleached with hypochlorite and sodium hydroxide. L1 starvation assay was adapted from a previously described protocol (3). Worms strains were grown and maintained at 20 °C as described (29). This result is consistent with the observation that miR-71 is specifically required for the starvation-induced stress response (Fig. S5). For example, we observed a robust retarded mutant phenotype in the vulval lineage but did not see obvious defects in seam cell differentiation or alae formation. Our data provide the experimental evidence that two components of the InsR pathway are likely direct targets of miR-71 in its role in a specific physiological process, L1 diapause (see a model in Fig. S5).
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.
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 further found that this survival rate reduction of ain-1 mutants was overcome by ectopic expression of the AIN-2 protein in the intestine but not in the muscle (Fig. 1A and Fig. S1A). 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. Furthermore, a recent study suggests that the expression of certain miRNAs is differentially regulated by starvation-induced dauer diapause (15). Consistent with these ideas, several recent lines of evidence suggest that miRNA let-7 and the heterochronic genes lin-42 and hbl-1 are required to regulate the starvation-induced dauer diapause (10–12) and that a number of miRNAs including lin-4 and mir-71 are involved in regulating life span (13, 14).
