Uncovering Cystic Fibrosis Carrier: Insights From a Heterozygous CFTR‐F508del Rabbit Model

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disorder frequently associated with impaired mucociliary clearance and bacterial infection. Individuals carrying a single cystic fibrosis transmembrane conductance regulator (CFTR) mutation exhibit partial CFTR dysfunction and are increasingly recognized as being at risk ...

Protoporphyrin IX-Dependent Antiviral Effects of 5-Aminolevulinic Acid against Feline Coronavirus Type II

Viruses
5-Aminolevulinic acid (5-ALA), a non-proteinogenic amino acid, is an intermediate in the biosynthesis of heme and exerts antiviral effects against feline coronavirus (FCoV); however, the underlying mechanisms remain unclear.

Molecular Mechanism of Heme Biosynthesis.

The Tohoku Journal of Experimental Medicine, 1997
Two of the major organs producing heme are bone marrow and the liver. delta-Aminolevulinate synthase (ALAS) plays the key role to regulate heme biosynthesis in hepatocytes as well as in erythroid cells. In the liver, nonspecific (or housekeeping) isozyme of ALAS (ALAS-N) is expressed to be regulated by its end product, heme, in a negative feedback ...

A Novel Pathway for the Biosynthesis of Heme in Archaea: Genome-Based Bioinformatic Predictions and Experimental Evidence [PDF]

, 2010
Heme is an essential prosthetic group for many proteins involved in fundamental biological processes in all three domains of life. In Eukaryota and Bacteria heme is formed via a conserved and well-studied biosynthetic pathway.

Erythropoietin induction in Hep3B cells is not affected by inhibition of heme biosynthesis

, 2000
Erythropoietin (Epo) is one of the physiologically important genes whose transcription is up-regulated by hypoxia. Our laboratory previously proposed that the sensor of this event is a heme protein which turns over rapidly.

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

Heme b in marine cyanobacteria and the (sub-) tropical North Atlantic

, 2012
Heme b is the iron containing prosthetic group to an important pool of iron proteins known as the hemoproteins. Hemoproteins are functionally diverse, playing key roles in photosynthetic and respiratory electron transfer (e.g. cytochrome b6f, photosystem

Use of Clotrimazole in Finfish Aquaculture: Mechanistic Insights, Limitations, and Future Directions for Antifungal Therapy

Animal Research and One Health, EarlyView.
This review critically evaluates clotrimazole as a potential antifungal for finfish aquaculture, highlighting strong mechanistic and in vitro efficacy against aquatic mycoses alongside major gaps in in vivo evidence, toxicokinetics, residue safety, and environmental risk, outlining priorities for responsible therapeutic development and regulatory ...

Regulation of hepatic heme synthesis by drugs, bile acids and nutrition : a transcriptional network regulating [delta]-aminolevulinic acid synthase 1 (ALAS1) [PDF]

, 2008
ALAS1 is the rate limiting enzyme of heme synthesis. It is highly inducible in liver in cases of increased heme demand, such as drug metabolism or in inducible hepatic porphyrias.

Spray‐Dried Engineered Escherichia coli Whole‐Cell Biocatalysts Enable Cell Recycling and In Vivo α‐Ketoglutarate and NADPH Regeneration for Efficient Codeine Manufacture

Biotechnology and Bioengineering, EarlyView.
ABSTRACT A recombinant whole‐cell biocatalytic approach provides several advantages over isolated enzymes, such as improved enzyme stability, in vivo cofactor regeneration, and the facilitation of cascade reactions within a single cell. Whole‐cell biocatalysis has gained attention in medicinal opioid production, due to its technical and economic ...
