This protein is responsible for restoring bonds in DNA chains and “correcting” errors caused by the duration and quality of wakefulness, oxidative stress, ultraviolet light, enzymatic errors and other aggressive factors.
Scientists conducted research based on optogenetic techniques, radiation and pharmacological preparations. The first experiments were done on zebrafish, which, like mammals, need sleep to recuperate. A connection was found between sleep and the PARP1 protein – if the expression of the protein was stimulated, a signal was sent to the brain about the need for sleep; if the protein was blocked, the fish could not sleep.
The minimum sleep time for DNA and strength restoration was also determined – 6 hours.
