Effects of cytosine arabinoside on the incorporation of pyrimidine nucleosides into hamster cells transformed by herpes simplex type 1 and type 2 viruses and by human cytomegalovirus

Acta Virologica

The incorporation of 3H-thymidine and 3H-deoxycytidine into acidoprecipitable fraction of hamster cells transformed by herpes simplex viruses type 1 and type 2 and of 3H-thymidine into hamster cells transformed by human cytomegalovirus was found to be resistant to the action of cytosine arabinoside. More 3H-thymidine was incorporated into these cells in the presence than in the absence of the drug. Similar stimulaton of 3H-thymidine uptake could be achieved by using unlabelled deoxycytidine instead of cytosine arabinoside. Incorporation of both nucleosides into spontaneously and SV40 transformed cells was efficiently inhibited by the drug.

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.
