Deoxycytidylate and deoxyguanylate kinase activity in pneumococci after exposure to known polyribonucleotides

W FirsheinM Sease


Polycytidylic acid and to a lesser extent polyadenylic acid enhance the activity of deoxycytidylate and deoxyguanylate kinases in resting cell suspensions of encapsulated pneumococci. The active intracellular materials appear to be oligomers of A and C, respectively. The stimulation of the kinase activities is amino-acid dependent and can be abolished by the addition of chloramphenicol. The addition of all eight naturally occurring deoxyribonucleosides and deoxyribonucleotides to cell suspensions containing the homopolymers leads to a selective enhancement of DNA synthesis.

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.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration

HLA Genetic Variation

HLA genetic variation has been found to confer risk for a wide variety of diseases. Identifying these associations and understanding their molecular mechanisms is ongoing and holds promise for the development of therapeutics. Find the latest research on HLA genetic variation here.
