The funnily adorable and resilient tardigrade , or water bear , just might withstand the Francis Scott Key to realize cancer treatment a lot more ( water- ) bearable . That ’s because a squad of researchers just found grounds that a protein produced by these microscopic creatures could protect our healthy cell from the depredation of radiation therapy .
Scientists at MIT , the University of Iowa , and elsewhere carry on the new study , publishedthis Wednesday inNature Biomedical Engineering . In experiments with mice , the inquiry team detect that the protein cut radiation therapy damage in normal cells , while still allowing the radiation therapy to place cancerous mobile phone . The findings could someday lead to an invaluable tote up - on discourse for many Cancer the Crab patients , the researchers say .
Tardigrades are extremophiles , notorious for their remarkable ability to survive some of the most inhospitable consideration on Earth ( and space ) . One of the consideration the dauntless critters acquire to withstand is extreme doses of actinotherapy — thousands of times more than a man can handle — and one of the trick they apply to resist that radiation is the production of something called thedamage suppressor protein , or Dsup . This protein , as the name imply , is thought to suppress radiation - induced DNA legal injury by binding to desoxyribonucleic acid strands and preventing them from break off apart as common .

The research team decided to test whether it was potential to safely transfer the tardigrade ’s trunk armor against radiation to other fauna , depart with computer mouse .
Using mRNA applied science , the squad made it possible for certain cell in its shiner to temporarily bring forth Dsup ( only a few hours ) , then they exposed the cadre to radiation . The researchers specifically pick out cells lining the mouth and rectum , since radiation is commonly used to treat Cancer in these areas .
Just as with tardigrade , the team ’s mouse appear to have added security against radiation impairment , the researchers found . In experiments with mice that had unwritten Crab , they also certify that the mRNA therapy did n’t spoil radiation ’s power to wipe out off nearby tumour cells .
“ The scheme may be broadly applicable to the protection of level-headed tissue from desoxyribonucleic acid - damage agent , ” the researcher wrote in their paper .
Of course , this research still is a farsighted way from being applicable to human cancer affected role , and it will take more study and tweaking to make this technology safe and practical for medical consumption .
The scientist plan to create an upgraded version of the protein that ’s less likely to provoke an unwanted reply from our immune system , for representative . Researchers elsewhere have alsorecently discoveredtardigrades that are even more resistant to irradiation , suggesting that Dsup is n’t the only radiation - proof tool we can borrow from them . But if the squad ’s work does continue to progress , it could eventually provide widespread benefit to the roughly50 to 60 % of cancer patientswho undergo radiation therapy .
The protein could even perchance be used to protect astronauts from quad - bear on radiation or to protect cancer patient role from other sources of intervention - induced desoxyribonucleic acid damage , such as chemotherapy drugs , the researchers say .
“ Radiation can be very helpful for many tumour , but we also recognize that the side result can be limiting , ” field co - author Giovanni Traverso , an associate prof of mechanical engineering at MIT and a gastroenterologist at Brigham and Women ’s Hospital , toldMIT News . “ There ’s an unmet need with respect to helping affected role extenuate the risk of damage adjacent tissue paper . ”
tardigrade have long been one of the most fascinating animals around because of their manifold invulnerabilities . If we ’re prosperous , we might one sidereal day harness a second of that superpower for ourselves .
