Abstract

We sought to isolate, clone, and determine the nucleic acid sequence of the guinea pig adenovirus (GPAdV) hexon gene. From this, the amino acid sequence of the cloned portion was deduced and compared with a set of mastadenovirus hexons. The DNA isolated from a histologic section of infected guinea pig lung was subjected to high-fidelity amplification, using degenerate primers complementary to a conserved nucleic acid sequence near the 3' end of the hexon gene of mastadenoviruses and a 5' primer from GenBank accession No. X95630 (GPAdV hexon gene partial sequence). The amplified product was cloned, the nucleic acid sequence was determined, and the amino acid sequence was deduced and compared with the hexon amino acid sequences of 25 mastadenoviruses. The cloned fragment comprised 1,603 base pairs (bp) [approximately 50%]) of the hexon. Of the initial 278 nucleic acids of the clone, 276 were identical with GenBank accession No. X95630, and the deduced amino acid sequences of both were identical. The deduced GPAdV hexon amino acid sequence from the clone aligned with structural regions NT, V1, DE1, and FG1 described for human adenovirus types 2 and 5. The GPAdV hexon had < 50% similarity in amino acid sequence, compared with hexon...Continue Reading

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

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.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
