A mitochondrial superoxide theory for oxidative stress diseases and aging

Indo H.; Yen H.; Nakanishi I.; Matsumoto K.; Tamura M.; Nagano Y.; Matsui H.; Gusev O.; Cornette R.; Okuda T.; Minamiyama Y.; Ichikawa H.; Suenaga S.; Oki M.; Sato T.; Ozawa T.; Clair D.; Majima H. (2015)

© 2015 JCBN. Fridovich identified CuZnSOD in 1969 and manganese superoxide dismutase (MnSOD) in 1973, and proposed "the Superoxide Theory," which postulates that superoxide (O2 -) is the origin of most reactive oxygen ...
A new anhydrobiotic midge from Malawi, Polypedilum pembai sp.n. (Diptera: Chironomidae), closely related to the desiccation tolerant midge, Polypedilum vanderplanki Hinton

Cornette R.; Yamamoto N.; Yamamoto M.; Kobayashi T.; Petrova N.; Gusev O.; Shimura S.; Kikawada T.; Pemba D.; Okuda T. (2017)

© 2017 The Royal Entomological Society The sleeping chironomid (Polypedilum vanderplanki Hinton) lives on temporary rock pools in the semi-arid tropical regions of Africa. Its larvae are able to survive the dry season in ...
Anhydrobiosis-associated nuclear DNA damage and repair in the sleeping chironomid: Linkage with radioresistance

Gusev O.; Nakahara Y.; Vanyagina V.; Malutina L.; Cornette R.; Sakashita T.; Hamada N.; Kikawada T.; Kobayashi Y.; Okuda T. (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 ...
Chironomid Midges (Diptera, Chironomidae) Show Extremely Small Genome Sizes

Cornette R.; Gusev O.; Nakahara Y.; Shimura S.; Kikawada T.; Okuda T. (2015)

© 2015 Zoological Society of Japan. Chironomid midges (Diptera; Chironomidae) are found in various environments from the high Arctic to the Antarctic, including temperate and tropical regions. In many freshwater habitats, ...
Combined metabolome and transcriptome analysis reveals key components of complete desiccation tolerance in an anhydrobiotic insect

Ryabova A.; Cornette R.; Cherkasov A.; Watanabe M.; Okuda T.; Shagimardanova E.; Kikawada T.; Gusev O. (2020)

© 2020 National Academy of Sciences. All rights reserved. Some organisms have evolved a survival strategy to withstand severe dehydration in an ametabolic state, called anhydrobiosis. The only known example of anhydrobiosis ...
Comparative genome sequencing reveals genomic signature of extreme desiccation tolerance in the anhydrobiotic midge

Gusev O.; Suetsugu Y.; Cornette R.; Kawashima T.; Logacheva M.; Kondrashov A.; Penin A.; Hatanaka R.; Kikuta S.; Shimura S.; Kanamori H.; Katayose Y.; Matsumoto T.; Shagimardanova E.; Alexeev D.; Govorun V.; Wisecaver J.; Mikheyev A.; Koyanagi R.; Fujie M.; Nishiyama T.; Shigenobu S.; Shibata T.; Golygina V.; Hasebe M.; Okuda T.; Satoh N.; Kikawada T. (2014)

© 2014 Macmillan Publishers Limited. All rights reserved. Anhydrobiosis represents an extreme example of tolerance adaptation to water loss, where an organism can survive in an ametabolic state until water returns. Here ...
Diversity of the expression profiles of late embryogenesis abundant (LEA) protein encoding genes in the anhydrobiotic midge Polypedilum vanderplanki

Hatanaka R.; Gusev O.; Cornette R.; Shimura S.; Kikuta S.; Okada J.; Okuda T.; Kikawada T. (2015)

© 2015, Springer-Verlag Berlin Heidelberg. Main conclusion: In the anhydrobiotic midgePolypedilum vanderplanki, LEA family proteins are likely to play distinct temporal and spatial roles in the larvae throughout the process ...
Genetic background of enhanced radioresistance in an anhydrobiotic insect: transcriptional response to ionizing radiations and desiccation

Ryabova A.; Mukae K.; Cherkasov A.; Cornette R.; Shagimardanova E.; Sakashita T.; Okuda T.; Kikawada T.; Gusev O. (2017)

© 2016, Springer Japan.It is assumed that resistance to ionizing radiation, as well as cross-resistance to other abiotic stresses, is a side effect of the evolutionary-based adaptation of anhydrobiotic animals to dehydration ...
Karyotypical characteristics of two allopatric African populations of anhydrobiotic Polypedilum Kieffer, 1912 (Diptera, Chironomidae) originating from Nigeria and Malawi

Petrova N.; Cornette R.; Shimura S.; Gusev O.; Pemba D.; Kikawada T.; Zhirov S.; Okuda T. (2015)

© Ninel A. Petrova et al. The African chironomid Polypedilum vanderplanki Hinton, 1951 is the only chironomid able to withstand almost complete desiccation in an ametabolic state known as anhydrobiosis. The karyotypes of ...
MnSOD downergulation induced by extremely low 0.1 mGy single and fractionated X-rays and microgravity treatment in human neuroblastoma cell line, NB-1

Indo H.; Tomiyoshi T.; Suenaga S.; Tomita K.; Suzuki H.; Masuda D.; Terada M.; Ishioka N.; Gusev O.; Cornette R.; Okuda T.; Mukai C.; Majima H. (2015)

Copyright © 2015 JCBN. A human neuroblastoma cell line, was treated with 24 h of microgravity simulation by clinostat, or irradiated with extremely small X-ray doses of 0.1 or 1.0 mGy using single and 10 times fractionation ...
Planetary protection challenges in space exploration missions and ways of their resolution with account of Russian exobiology experiments
