Metabolomic analysis reveals the molecular mechanism related to leg abnormality in broilers
The graphical abstract shows the principal results of this study. Compared to the leg normal broilers, the serum calcium to phosphorus ratio was extremely decreased in the group with deformed leg bones. Additionally, a total of nine differential metabolites significantly associated with leg abnormalities and serum calcium and phosphorus levels were ...

Electric Field Driven Torque in ATP Synthase [PDF]
Fo-ATP synthase (Fo) is a rotary motor that converts potential energy from ions, usually protons, moving from high- to low-potential sides of a membrane into torque and rotary motion. Here we propose a mechanism whereby electric fields emanating from the proton entry and exit channels act on asymmetric charge distributions in the c-ring, due to ...

Background: The mechanism whereby IL-1β induces islet PGE2 production and inhibition of insulin secretion is unclear. Results: Basal COX-2 protein levels are stimulated by IL-1β; mPGES-1 levels are not.

Objectives Chondrocyte metabolic dysfunction plays an important role in osteoarthritis (OA) development during aging and obesity. Protein post‐translational modifications (PTMs) have recently emerged as an important regulator of cellular metabolism. We aim to study one type of PTM, lysine malonylation (MaK) and its regulator Sirt5 in OA development ...

Fluorescent nanodiamonds for FRET-based monitoring of a single biological nanomotor FoF1-ATP synthase [PDF]
Color centers in diamond nanocrystals are a new class of fluorescence markers that attract significant interest due to matchless brightness, photostability and biochemical inertness. Fluorescing diamond nanocrystals containing defects can be used as markers replacing conventional organic dye molecules, quantum dots or autofluorescent proteins. They can

Human glutathione dependent prostaglandin E synthase: gene structure and regulation [PDF]
A P1 clone containing the gene for human glutathione dependent PGE synthase (PGES) was isolated and characterized. The gene is divided into three exons, spans 14.8 kb and was localized to chromosome 9q34.3. In A549 cells, the protein and activity levels of PGES were increased by interleukin‐1β. This increase was prevented by phenobarbital.

Ammonia (NH3), a toxic gas, has deleterious effects on chicken health in intensive poultry houses. MicroRNA can mediate inflammation. The complex molecular mechanisms underlying NH3 inhalation–caused inflammation in animal kidneys are still unknown.

Monitoring transient elastic energy storage within the rotary motors of single FoF1-ATP synthase by DCO-ALEX FRET [PDF]
The enzyme FoF1-ATP synthase provides the 'chemical energy currency' adenosine triphosphate (ATP) for living cells. Catalysis is driven by mechanochemical coupling of subunit rotation within the enzyme with conformational changes in the three ATP binding sites.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).
