Abstract

The papillomavirus E5 genes play an important role in the induction of proliferation of infected cells, and these HPV genomic regions are affected by the events leading to integration of genital HPVs. Two HPV18 E5-related, transcribed mouse sequences, HC1 and Q300, have recently been described. We searched for human equivalents to these sequences, and isolated a clone with a 9.6 kb insert (633b) from a laryngeal carcinoma DNA library, that strongly cross-hybridised with both the HPV18 E5 and HC1 sequences. Restriction and Southern blot analysis showed that 633b is a single copy sequence without rearrangements and viral sequences. The E5-related region is transcribed, producing a 1.9 kb RNA band detected in the poly(A)+ RNA from different cell lines tested. Sequence alignments showed a close similarity to the HC1 and HPV18 E5 sequences, as well as to Q300 and different viral and human growth factors, allowing to fit a putative phylogenetic tree. The corresponding human gene was named PE5L. It was mapped to the short arm of chromosome 7, at 7p13-14 as determined by in situ hybridisation. A genomic region with similarities to HPV E5 sequences may constitute an HPV-DNA integration target, which is often located near chromosomal bre...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.
