A phase transition modulates the protective function of a tardigrade disordered protein during desiccation. [PDF]
Abstract Water is essential for active life, yet some organisms, such as tardigrades, can survive prolonged periods of drying‐induced dormancy. Cytoplasmic abundant heat‐soluble (CAHS) proteins are disordered proteins that undergo a phase transition from the solution to gel state.

Anhydrobiosis: The Model Worm as a Model? [PDF]
New work now shows that the dauer larvae of Caenorhabditis elegans can survive anhydrobiotically. The genetic tractability of this model organism may be useful in studying how organisms survive when losing most or all of their water.

Metabolite phosphatase from anhydrobiotic tardigrades. [PDF]
In this study, we determined the crystal structure of a Ferritin‐like protein widely distributed among intriguing organisms such as tardigrades, which show tolerance to extreme environmental conditions. We identified a dinuclear metal‐binding site, which we found harbors phosphatase activity toward several metabolites, including compounds related to ...

Anhydrobiosis-associated nuclear DNA damage and repair in the sleeping chironomid: linkage with radioresistance. [PDF]
Anhydrobiotic chironomid larvae can withstand prolonged complete desiccation as well as other external stresses including ionizing radiation. To understand the cross-tolerance mechanism, we have analyzed the structural changes in the nuclear DNA using ...

Tun formation is not a prerequisite for desiccation tolerance in the marine tidal tardigrade Echiniscoides sigismundi [PDF]
The so-called ‘tun’ state is best known from limno-terrestrial tardigrades and rotifers that rely on this compact body shape for anhydrobiotic survival.

DAF-16/FoxO in Caenorhabditis elegans and its role in metabolic remodeling [PDF]
DAF-16, the only forkhead box transcription factors class O (FoxO) homolog in Caenorhabditis elegans, integrates signals from upstream pathways to elicit transcriptional changes in many genes involved in aging, development, stress, metabolism, and ...

Upon desiccation, some tardigrades enter an ametabolic dehydrated state called anhydrobiosis and can survive a desiccated environment in this state. For successful transition to anhydrobiosis, some anhydrobiotic tardigrades require pre-incubation under ...

Survival potential of the anhydrobiotic nematode Panagrolaimus superbus submitted to extreme abiotic stresses [PDF]
Most organisms die when confronting extreme desiccation regimes, as observed in severe and prolonged droughts. However, some organisms are able to withstand such conditions by entering into a unique state of true suspended animation known as ...
