Radiation tolerance in the tardigrade Milnesium tardigradum
TLDR
Gamma-irradiation shortened average life span in a dose-dependent manner both in hydrated and anhydrobiotic groups and made tardigradum sterile. Expand
Dehydration-induced expression of LEA proteins in an anhydrobiotic chironomid.
TLDR
This first description of LEA protein genes in arthropods suggests that this protein family is widespread throughout invertebrate phyla, and that animals, plants, and microorganisms possess similar mechanisms for combating dehydration stress. Expand
Vitrification is essential for anhydrobiosis in an African chironomid, Polypedilum vanderplanki
Anhydrobiosis is an extremely dehydrated state in which organisms show no detectable metabolism but retain the ability to revive after rehydration. Thus far, two hypotheses have been proposed toExpand
Trehalose transporter 1, a facilitated and high-capacity trehalose transporter, allows exogenous trehalose uptake into cells
TLDR
The isolated and characterized the functions of a facilitated trehalose transporter from an anhydrobiotic insect, Polypedilum vanderplanki, and TRET1 was found to function in mammalian cells, suggesting that it confers tre Halose permeability on cells, including those of vertebrates as well as insects.

Purification and characterization of silkworm hemocytes by flow cytometry.
TLDR
An array of flow cytometric analyses is used to characterize silkworm hemocytes with various molecular probes, such as propidium iodide, green fluorescence protein, monoclonal antibodies, and fluorescent lectins, which provide most reliable results for the isolation of the hemocyte subsets. Expand
Establishment of a rearing system of the extremotolerant tardigrade Ramazzottius varieornatus: a new model animal for astrobiology.
TLDR
The successful rearing of the herbivorous tardigrade, Ramazzottius varieornatus, by supplying the green alga Chlorella vulgaris as food is reported, and it is reported that the reared individuals of this species had an anhydrobiotic capacity throughout their life cycle in egg, juvenile, and adult stages. Expand
Effects of silkworm paralytic peptide on in vitro hematopoiesis and plasmatocyte spreading.
TLDR
The results suggest that BmPP plays important roles both in hematopoietic regulation and in the hemocyte immune reaction of the silkworm. Expand
Hormonal control of a metamorphosis-specific transcriptional factor Broad-Complex in silkworm.
TLDR
BR-C mRNAs are inducible by 20E only in the absence of JH, a finding that explains their metamorphosis-specific expression. Expand
In vitro studies of hematopoiesis in the silkworm: cell proliferation in and hemocyte discharge from the hematopoietic organ.
TLDR
The effects of 20-hydroxyecdysone and juvenile hormone-I showed a weak, but significant, hematopoietic activity, whereas JH-I did not, suggesting that a part of larval hepatopoiesis is endocrinally regulated. Expand
Anhydrobiosis-Associated Nuclear DNA Damage and Repair in the Sleeping Chironomid: Linkage with Radioresistance
TLDR
One of the factors explaining the relationship between radioresistance and the ability to undergo anhydrobiosis in the sleeping chironomid could be an adaptation to desiccation-inflicted nuclear DNA damage. Expand
