Abstract:
... Wound healing remains a challenge in burns and trauma fields. Adipose derived stem cells exosomes (AD-exos) had been confirmed to have a positive effect on the wound healing and the migration and proliferation of keratinocyte. However, the mechanism of the AD-exos is still unclear. The objective of this article is to observe the function of the miR-21 expressed in the adipose AD-exos and the effec ...

Abstract:
... Serum amyloid A variant 1.1 (SAA1.1) is an acute phase protein. In response to injury, inflammation or infection its production increases highly, which may lead to aggregation of the protein and accumulation of its deposits in various organs. Due to the cellular toxicity of the aggregates, as well as the fact that accumulated deposits are a burden that obstructs proper functioning of the affected ...

The biological role of taurine up-regulated gene 1 (TUG 1) in hypoxia-induced damage of cardiomyocytes is still poorly defined. Our study aimed to investigate the function of TUG 1 in hypoxia-treated cardiomyocytes and the possible underlying mechanism. TUG 1 and miR-133a expression levels in hypoxia-cultured human AC16 c ...

Abstract:
... Cold atmospheric plasma (CAP) is a promising means for various biomedical applications, including cancer therapy. Although the biological action of CAP is considered to be brought about by synergistic effects of reactive species and electrical factors of CAP, limited information is currently available on the contribution of electrical factors to CAP-induced cell responses. We have previously demon ...

Abstract:
... Human peroxidasin 1 (hsPxd01) is a homotrimeric multidomain heme peroxidase embedded in the extracellular matrix. It catalyses the two-electron oxidation of bromide by hydrogen peroxide to hypobromous acid which mediates the formation of essential sulfilimine cross-links between methionine and hydroxylysine residues in collagen IV. This confers critical structural reinforcement to the extracellula ...

Abstract:
... Preadipocyte differentiation and lipid synthesis are critical steps for intramuscular fat (IMF) deposition and lipid metabolism homeostasis. IMF content of beef not only determines the ratio of muscle to adipose, but also determines the beef quality, flavor, and sensory characteristics. Maintaining lipid metabolism homeostasis is the key means of preventing and treating diabetes, obesity, and othe ...

Abstract:
... Aldehyde dehydrogenases catalyze the NAD(P)⁺-dependent oxidation of aldehydes to their corresponding carboxylic acids. The three-dimensional structures of the human ALDH1A enzymes were recently obtained, while a complete kinetic characterization of them, under the same experimental conditions, is lacking. We show that the three enzymes, ALDH1A1, ALDH1A2 and ALDH1A3, have similar topologies, althou ...

We describe here a simple strategy to characterize transport specificity of NADH:quinone oxidoreductases, using Na⁺-translocating (NQR) and H⁺-translocating (NDH-1) enzymes of the soil bacterium Azotobactervinelandii as the models. Submillimolar concentrations of Na⁺ and Li⁺ increased the rate of deaminoNADH oxidation by the inverted membrane vesicles prepared from the NDH-1-deficient strain. The ...

Because long-term occupational exposure to low concentrations of acrylamide (ACR) has the potential to cause neurological damage, it is important to identify biomarkers that can be used to evaluate this risk. In the present study, urine metabolomics of the ACR-exposed and non-exposed groups to identify potential metabolites was carried out using ultra high performance liquid chromatography coupled ...

LMW-PTP belong to the Cys-based PTP class II protein family. Here, we show that LMW-PTP can be categorized into two different groups, referred as class II subdivision I (class II.I) and subdivision II (class II.II). Using BPtpA from the opport ...

Abstract:
... Although l-ascorbate (vitamin C) is an important biological antioxidant, its degradation pathways in vivo remain incompletely characterised. Ascorbate is oxidised to dehydroascorbic acid, which can be either hydrolysed to diketogulonate (DKG) or further oxidised. DKG can be further degraded, oxidatively or non-oxidatively. Here we characterise DKG products formed non-enzymically and non-oxidativel ...

Abstract:
... Phenylglyoxal (PGO), known to cause post-translational modifications of Arg residues, was used to highlight the role of arginine residues of the F₁FO-ATPase, which may be crucial to yield the mitochondrial permeability transition pore (mPTP). In swine heart mitochondria PGO inhibits ATP hydrolysis by the F₁FO-ATPase either sustained by the natural cofactor Mg²⁺ or by Ca²⁺ by a similar uncompetitiv ...
