Deciphering the Biological Enigma—Genomic Evolution Underlying Anhydrobiosis in the Phylum Tardigrada and the Chironomid Polypedilum vanderplanki [PDF]
Insects, 2022 Anhydrobiosis, an ametabolic dehydrated state triggered by water loss, is observed in several invertebrate lineages. Anhydrobiotes revive when rehydrated, and seem not to suffer the ultimately lethal cell damage that results from severe loss of water in ...

How long can tardigrades survive in the anhydrobiotic state? A search for tardigrade anhydrobiosis patterns. [PDF]
PLoS ONE, 2023 Anhydrobiosis is a desiccation tolerance that denotes the ability to survive almost complete dehydration without sustaining damage. The knowledge on the survival capacity of various tardigrade species in anhydrobiosis is still very limited.

Recovery from anhydrobiosis in the tardigrade Paramacrobiotus experimentalis: Better to be young than old and in a group than alone [PDF]
HeliyonDesiccation-tolerant organisms can survive dehydration in a state of anhydrobiosis. Tardigrades can recover from anhydrobiosis at any life stage and are considered among the toughest animals on Earth.

Transcriptome analysis of the tardigrade Hypsibius exemplaris exposed to the DNA-damaging agent bleomycin [PDF]
Proceedings of the Japan Academy. Series B, Physical and Biological SciencesTardigrades are microscopic animals that are renowned for their capabilities of tolerating near-complete desiccation by entering an ametabolic state called anhydrobiosis.

Fibril Structure of Desiccation-Protective Tardigrade Protein CAHS-8. [PDF]
Angew Chem Int Ed EnglWe present the atomic structure of the fibril formed by an intrinsically disordered protein that has been shown to be responsible for remarkable environmental stress in tardigrades. X‐ray crystallography reveals a unique mechanism of fibril assembly whereby a single helix forms a stable, antiparallel coiled‐coil dimer, which then assembles into a ...

The phenomenon of anhydrobiosis—structural and functional changes in yeast cells [PDF]
Applied Microbiology and BiotechnologyAnhydrobiosis is a phenomenon that involves the ability of microorganisms to survive in an environment of virtually complete dehydration. Yeast cells in anhydrobiosis exhibit several structural and functional changes.

Possible roles of CAHS proteins from Tardigrade in osmotic stress tolerance in mammalian cells [PDF]
Cell Structure and FunctionAnhydrobiosis, a phenomenon in which organisms survive extreme dehydration by entering a reversible ametabolic state, is a remarkable example of survival strategies. This study focuses on anhydrobiosis in tardigrades, which are known for their resilience

Biomolecular condensates-Prerequisites for anhydrobiosis? [PDF]
Protein SciAbstractIt is often underappreciated that despite water being a requirement for life on Earth, organisms belonging to all taxonomic kingdoms have developed mechanisms to survive desiccation. These organisms, referred to as anhydrobiotes, accumulate specific biomolecules during or before drying that facilitate the survival of desiccation stress ...

Search for putative gene regulatory motifs in CAHS3, linked to anhydrobiosis in a tardigrade Ramazzottius varieornatus, in vivo and in silico. [PDF]
Genes CellsTardigrades can survive in an almost completely dehydrated state, known as anhydrobiosis, aided by proteins like CAHS3. Research using a newly developed tardigrade‐specific vector revealed that CAHS3 expression is most pronounced in the epidermis, suggesting tissue‐specific regulation rather than uniform expression.

Physiological and genetic regulation of anhydrobiosis in yeast cells. [PDF]
Arch Microbiol, 2023 AbstractAnhydrobiosis is a state of living organisms during which their metabolism is reversibly delayed or suspended due to a high degree of dehydration. Yeast cells, which are widely used in the food industry, may be induced into this state. The degree of viability of yeast cells undergoing the drying process also depends on rehydration.
