Bacterial-derived cyclic lipopeptides suppress dauer arrest in C. elegans.PMID:42779934
bioRxiv : the preprint server for biology2026-01-01

Secondary bacterial metabolites can regulate animal physiology, but the specific bacterial genes and molecules responsible for regulating, synthesizing, and transporting these molecules and the mechanisms by which they impact animal physiology often ...

AgeViva Modulates Inflammatory Responses, Autophagy, and Mitochondrial Homeostasis in BV-2 Cells and C. elegans.PMID:42783750
Metabolites2026-01-01

Background: Oxidative stress, neuroinflammation, impaired autophagy, and mitochondrial dysfunction are major contributors to ageing and neurodegenerative diseases. This study investigated whether AgeViva could counteract these processes by modulating...

Diapause and Developmental Arrest as Drivers of Population Resilience Through Stress.PMID:42538953
bioRxiv : the preprint server for biology2026-01-01

Dauer formation and L1 arrest are stress-responsive developmental strategies that enable Caenorhabditis elegans to survive unfavorable conditions. These responses are regulated by environmental cues, including food availability and pheromone signals ...

Aging, Dauer, and Stature Phenotypes Are Conferred by Structure-Directed Missense Mutations in the Endogenous AGE-1/Phosphatidylinositol 3-Kinase Catalytic Subunit.PMID:42313603
Aging cell2026-01-01

Phosphatidylinositol 3-kinase (PI3K) integrates insulin/IGF signaling (IIS) and Ras inputs to control lifespan, metabolism and growth. Yet the organismal consequences of selective structural perturbations remain poorly understood. Using structure-gui...

Natural variation in dauer pheromone production and sensing supports intraspecific competition in nematodes.PMID:24980503
Current biology : CB2014-01-01Bose N, Meyer JM, Yim JJ et al.

Dauer formation, a major nematode survival strategy, represents a model for small-molecule regulation of metazoan development [1-10]. Free-living nematodes excrete dauer-inducing pheromones that have been assumed to target conspecifics of the same ge...

Mammalian EAK-7 activates alternative mTOR signaling to regulate cell proliferation and migration.PMID:29750193
Science advances2018-01-01Nguyen JT, Ray C, Fox AL et al.

Nematode EAK-7 (enhancer-of-akt-1-7) regulates dauer formation and controls life span; however, the function of the human ortholog mammalian EAK-7 (mEAK-7) is unknown. We report that mEAK-7 activates an alternative mechanistic/mammalian target of rap...

CryoEM of endogenous mammalian V-ATPase interacting with the TLDc protein mEAK-7.PMID:35794005
Life science alliance2022-01-01Tan YZ, Abbas YM, Wu JZ et al.

V-ATPases are rotary proton pumps that serve as signaling hubs with numerous protein binding partners. CryoEM with exhaustive focused classification allowed detection of endogenous proteins associated with porcine kidney V-ATPase. An extra C subunit ...

ACaenorhabditis elegans dauer-inducing pheromone and an antagonistic component of the food supply.PMID:24318910
Journal of chemical ecology1984-01-01Golden JW, Riddle DL

The free-living soil nematodeCaenorhabditis elegans forms a nonfeeding dispersal stage at the second molt called the dauer larva when exposed to environmental cues indicating crowding and limited food. An improved bioassay, tenfold more sensitive tha...

Noncoding RNA Regulation of Dormant States in Evolutionarily Diverse Animals.PMID:31714856
The Biological bulletin2019-01-01Reynolds JA

Dormancy is evolutionarily widespread and can take many forms, including diapause, dauer formation, estivation, and hibernation. Each type of dormancy is characterized by distinct features; but accumulating evidence suggests that each is regulated by...

Microbiota succession influences nematode physiology in a beetle microcosm ecosystem.PMID:38879542
Nature communications2024-01-01Lo WS, Sommer RJ, Han Z

Unravelling the multifaceted and bidirectional interactions between microbiota and host physiology represents a major scientific challenge. Here, we utilise the nematode model, Pristionchus pacificus, coupled to a laboratory-simulated decay process o...

Claims (505)

supportskpc-1regulationkpc-1

The K. aerogenes infection affects age-1 regulation through the furin-like proprotein convertase (kpc-1); the absence of kpc-1 affects environment-dependent dauer formation.

supportsDAF-12regulationlet-7

In unfavorable conditions, the DAF-16/FOXO transcription factor and the DAF-12 nuclear hormone receptor in its ligand-free state promote dauer formation and oppose the expression of let-7 family microRNAs, thus pausing developmental progression during dauer.

supportsAGE-1causes_phenotypevariant

Unexpectedly, a putative AGE-1 variant defective in Ras association, together with a complementary Ras effector-binding mutation, produced enlarged animals with reduced dauer formation.

supportsdaf-16regulationdaf-7

Furthermore, lack of ets-10p::gfp expression early in the second larval stage partially predicts which daf-16 ; daf-7 larvae will bypass dauer formation.

supportsage-1regulationkpc-1

The K. aerogenes infection affects age-1 regulation through the furin-like proprotein convertase (kpc-1); the absence of kpc-1 affects environment-dependent dauer formation.

In unfavorable conditions, the DAF-16/FOXO transcription factor and the DAF-12 nuclear hormone receptor in its ligand-free state promote dauer formation and oppose the expression of let-7 family microRNAs, thus pausing developmental progression during dauer.

supportsdaf-2causes_phenotypelong

From this, we found that the effects of exogenous sugars on the phenotype of daf-2 mutant animals is dependent on the function of pyruvate dehydrogenase in bacteria and that the loss of bacterial pyruvate dehydrogenase genes (ex. aceE) is sufficient to mimic the effects of dietary sugars on dauer formation, longevity, and gene expression in insulin signaling deficient animals.

supportsAGE-1causes_phenotypelarge

Unexpectedly, a putative AGE-1 variant defective in Ras association, together with a complementary Ras effector-binding mutation, produced enlarged animals with reduced dauer formation.

supportsdaf-16regulationdaf-16

The FOXO ortholog daf-16 promotes dauer formation, but daf-16 mutants can enter dauer with incomplete penetrance in combination with a mutation in daf-7 /TGFβ.

supportsDAF-16regulationdaf-16

Timed auxin-mediated depletion of DAF-16 indicated that daf-16 is required before dauer formation, rather than after dauer, to prevent reiterative seam cell fates in post-dauer larvae and adults.
