Antioxidant Response during the Kinetics of Anhydrobiosis in Two Eutardigrade Species

open access: yesLife, 2022
Anhydrobiosis, a peculiar adaptive strategy existing in nature, is a reversible capability of organisms to tolerate a severe loss of their body water when their surrounding habitat is drying out.

Fibril Structure of Desiccation-Protective Tardigrade Protein CAHS-8. [PDF]

open access: yesAngew Chem Int Ed Engl
We 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 ...

Verification of Hypsibius exemplaris Gąsiorek et al., 2018 (Eutardigrada; Hypsibiidae) application in anhydrobiosis research.

open access: yesPLoS ONE, 2022
Anhydrobiosis is considered to be an adaptation of important applicative implications because it enables resistance to the lack of water. The phenomenon is still not well understood at molecular level.

Search for putative gene regulatory motifs in CAHS3, linked to anhydrobiosis in a tardigrade Ramazzottius varieornatus, in vivo and in silico. [PDF]

open access: yesGenes Cells
Tardigrades 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.

Mitochondrial alternative oxidase contributes to successful tardigrade anhydrobiosis

open access: yesFrontiers in Zoology, 2021
Anhydrobiosis can be described as an adaptation to lack of water that enables some organisms, including tardigrades, to survive extreme conditions, even some that do not exist on Earth.

Cas9-mediated genome editing reveals a significant contribution of calcium signaling pathways to anhydrobiosis in Pv11 cells

open access: yesScientific Reports, 2021
Pv11 is an insect cell line established from the midge Polypedilum vanderplanki, whose larval form exhibits an extreme desiccation tolerance known as anhydrobiosis.

Metabolite phosphatase from anhydrobiotic tardigrades. [PDF]

open access: yesFEBS J
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 ...

A phase transition modulates the protective function of a tardigrade disordered protein during desiccation. [PDF]

open access: yesProtein Sci
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-associated nuclear DNA damage and repair in the sleeping chironomid: linkage with radioresistance. [PDF]

open access: yesPLoS ONE, 2010
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 ...

Suggested Involvement of PP1/PP2A Activity and De Novo Gene Expression in Anhydrobiotic Survival in a Tardigrade, Hypsibius dujardini, by Chemical Genetic Approach.

open access: yesPLoS ONE, 2015
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 ...
