On the mechanism of a radiation-induced change in enzymic differentiation during development

Radiation and Environmental Biophysics
A M KuzinT E Ushakova


In experiments on glucose-6-phosphatase and tyrosine aminotransferase it was shown that radiation induces changes in enzymic differentiation in perinatal rat liver. A study was made of the probable reasons for the observed changes. It was shown that the macromolecular system of the protein enzyme synthesis was not damaged by the radiation doses used. The observed decrease in glucose-6-phosphatase activity during late embryogenesis, after pre-irradiation at early organogenesis, is eliminated by administration of exogenous thyroxine. A radiation-induced rise in the tyrosine aminotransferase activity during the perinatal period correlated with the cyclic AMP system status. It is proposed that modification of enzymic differentiation after irradiation results from the change in the amount of inductors.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Separation Anxiety

Separation anxiety is a type of anxiety disorder that involves excessive distress and anxiety with separation. This may include separation from places or people to which they have a strong emotional connection with. It often affects children more than adults. Here is the latest research on separation anxiety.

KIF1A Associated Neurological Disorder

KIF1A associated neurological disorder (KAND) is a rare neurodegenerative condition caused by mutations in the KIF1A gene. KAND may present with a wide range and severity of symptoms including stiff or weak leg muscles, low muscle tone, a lack of muscle coordination and balance, and intellectual disability.
