Zebrafish - a species of freshwater ray-finned fish of the carp family - a model organism in biology
Hibernation is a physiological condition in many species that protects them from harsh conditions such as lack of food and low ambient temperatures.
Human reproduction of hibernation can protectastronauts from the harsh conditions of space flight, which include problems such as radiation exposure, wasting of bones and muscles, aging and vascular problems. The researchers believe that if astronauts hibernate while traveling, these difficulties can be solved.
The research is published in the journal MDPI Cells.
Scientists exposed zebrafish to exposureradiation similar to a six-month trip to Mars. The researchers found that this radiation causes signs of oxidative stress, increased stress levels, and cell cycle arrest in zebrafish.
The researchers then numbed the secondgroups of zebrafish who were then exposed to the same dose of radiation and analyzed their gene expression patterns. The aim is to evaluate protective effects during an induced state of physical or mental inactivity.
The results showed that numbness lowers the metabolic rate in zebrafish and creates a radioprotective effect, protecting against the harmful effects of radiation.
Understanding how lower metabolic rates can provide protection from radiation exposure and help humans achieve this kind of hibernation for space travelers and explorers.
