Identification of stable reference genes for quantitative gene expression analysis in the duodenum of meat-type ducks

open access: yesFrontiers in Veterinary Science, 2023
Quantitative polymerase chain reaction (qPCR) is an important method to detect gene expression at the molecular level. The selection of appropriate housekeeping genes is the key to accurately calculating the expression level of target genes and ...

Mortality in Pedigrees with Acute Intermittent Porphyria

open access: yesLife, 2022
High mortality rates have been reported in historical cohorts of acute intermittent porphyria (AIP) patients. The mortality associated with (hydroxymethylbilane synthase) HMBS variant heterozygosity is unknown. This study estimates all-cause mortality in

Metabolic and molecular events occurring during chromoplast biogenesis [PDF]

open access: yes, 2011
Chromoplasts are nonphotosynthetic plastids that accumulate carotenoids. They derive from other plastid forms, mostly chloroplasts. The biochemical events responsible for the interconversion of one plastid form into another are poorly documented. However,

Studies on the mechanism of hydroxymethylbilane synthase concerning the role of arginine residues in substrate binding [PDF]

open access: bronzeBiochemical Journal, 1991
The role of conserved arginine residues in hydroxymethylbilane synthase was investigated by replacing these residues in the enzyme from Escherichia coli with leucine residues by using site-directed mutagenesis. The kinetic parameters for these mutant enzymes and studies on the formation of intermediate enzyme-substrate complexes indicate that several ...

Acute Intermittent Porphyria in a Man with Dual Enzyme Deficiencies

open access: yesCase Reports in Genetics, 2020
Porphyrias are a heterogeneous group of metabolic disorders that result from the altered activity of specific enzymes of the heme biosynthetic pathway and are characterized by accumulation of pathway intermediates.

Improved biosynthesis of heme in Bacillus subtilis through metabolic engineering assisted fed-batch fermentation

open access: yesMicrobial Cell Factories, 2023
Background Heme is an iron/porphyrin complex compound, widely used in the health care, food, and pharmaceutical industries. It is more advantageous and attractive to develop microbial cell factories to produce heme by fermentation, with lower production ...

The effect of cigarette smoke exposure on the development of inflammation in lungs, gut and joints of TNFΔARE mice [PDF]

open access: yes, 2015
The inflammatory cytokine TNF-alpha is a central mediator in many immune-mediated diseases, such as Crohn's disease (CD), spondyloarthritis (SpA) and chronic obstructive pulmonary disease (COPD).
