Have they identified the genes behind frogs being able to produce antifreeze and surviving freezing themselves that way? Can anyone shed more light on frogs freezing themselves? thanks
Mike H said:In the link provided in the earlier discussion, the scientist interviewed addressed the possibility of freezing humans. It's too early to say anything definitively. Perhaps in a century (or perhaps sooner, or later, it's impossible to predict) we will be able to handle cryoprotectant delivery and extraction for an entire human body and know how to simultaneously freeze all organ systems. But right now, your guess is as good as mine.
The purpose of studying frog survival and their genes related to antifreeze and freezing abilities is to gain a better understanding of how these animals are able to survive in extreme cold temperatures. By identifying and studying the specific genes responsible for their antifreeze and freezing abilities, we can potentially apply this knowledge to developing new strategies for human cryopreservation and other medical applications.
Frogs have unique physiological adaptations that allow them to survive freezing temperatures. They produce special proteins and sugars that act as antifreeze, preventing ice crystals from forming in their cells and causing damage. They also have the ability to lower their metabolic rate and enter a state of hibernation, which helps them conserve energy and survive the cold.
The ability to survive freezing temperatures is a crucial adaptation for frogs that live in cold climates. It allows them to survive harsh winters and gives them a competitive advantage over other animals that cannot withstand such extreme conditions. Additionally, studying these abilities can provide valuable insights into the mechanisms of cryopreservation, which has potential applications in medicine and conservation efforts.
Scientists are using a combination of techniques such as genetic sequencing, gene expression analysis, and genetic engineering to identify and study the genes related to antifreeze and freezing abilities in frogs. By comparing the genomes of different frog species and studying how these genes are expressed in response to cold temperatures, researchers can gain a better understanding of their function and potential applications.
As with any scientific research involving animals, there are potential risks and ethical concerns that need to be considered. These may include the impact on wild frog populations, the use of genetically modified frogs, and the potential for unintended consequences. However, these concerns are carefully evaluated and addressed by researchers to ensure that their studies are conducted responsibly and ethically.
