Abstract

The effect of linoleic acid hydroperoxide on replication of adenovirus type 2 DNA in cultured endothelial cells of bovine aorta was studied to elucidate the deleterious effect of lipid peroxides on replication of DNA in the arterial endothelial cells. When, just after the infection, the cells were incubated with 1 nmol (measured by the thiobarbituric acid reaction and expressed in terms of malondialdehyde) of the hydroperoxide, the replication of adenovirus type 2 DNA was markedly reduced. The level of the messenger RNA for adenovirus type 2 DNA polymerase was also reduced. In accordance with the reduction of the messenger RNA, the synthesis of the polymerase in the cells was reduced. The inhibition of DNA replication in the arterial endothelial cells by lipid peroxides was discussed in relation to atherogenesis.

COVID-19

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.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.
