Abstract

Neuropathy target esterase (NTE) was proposed as the initial target during the process of organophosphate-induced delayed neuropathy (OPIDN) in human and some sensitive animals. Adult hens are usually the animal model for experimental studies of OPIDN. However, little is known about the sequence and characteristics of chicken NTE. We report here the cloning of the 5' and 3' cDNA ends of chicken NTE through rapid amplification of cDNA ends (RACE) and their expression profiles in different tissues with northern blotting. The cloned 3' cDNA end of chicken NTE is 801 base pair (bp) in length with an open reading frame (ORF) of 379 bp. It contains a termination codon (TAG) and a 422-nucleotide noncoding sequence with the polyA sequence (GenBank accession no. DQ126678). The chicken NTE 5' cDNA end is 665 bp in length with an ORF of 552 bp. It contains an initiation codon (ATG) and a 113-bp untranslated region (GenBank accession no. DQ126677). The deduced proteins from 5' and 3' cDNA ends have a high degree of homology to humans and mouse NTE at the amino acid level. Chicken NTE is suggested to be a transmembrane protein by the transmembrane helix prediction of the deduced N-terminal sequence. The chicken NTE gene is expressed as a 4....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.
