  Another significant group of 5α-reductase inhibitors is the steroidal 3-carboxylic CGP 35348 synthesis derivatives (relevant examples in Fig. 5), which were designed to mimic the putative enzyme-bound enolate intermediate. This was achieved by introducing sp2-hybridized centers at C3 and C4 and an a

  2024-07-17

  

  Introduction Lipoxygenases (LOXs) are a heterogeneous family of enzymes that catalyze the peroxidation of polyunsaturated fatty acids (PUFAs). By oxidizing free PUFAs, they were shown to contribute to the generation of various bioactive lipid mediators. However, LOX-mediated oxidation of PUFAs es

  Results Discussion Context-specific and dynamic post-translational protein modifications are well-established regulators of the signaling pathways that protect eukaryotic DNA integrity during the tremendous task of replication. Advancements in speed, resolution, and sensitivity of MS-based tec

  In vascular endothelial cells, L-arginine produces nitric oxide (NO) under the action of nitric oxide synthase (NOS), and nitric oxide can activate guanylate cyclase to produce a large amount of cGMP, thereby relaxing vascular smooth muscle and expanding blood vessels. Numerous studies have confirme

  The objectives of this study were to investigate 1) the mRNA and protein expression of apelin and APJ in porcine ovarian follicles of different sizes, and their immunolocalization and concentrations in follicular fluid and ovarian follicle, and 2) the direct effect of recombinant human apelin-13 on

  2024-07-17

  

  The reasons why antibiotic treatment may be detrimental are diverse. First, it may result in disruption of multifaceted microbe–microbe, as well as microbe–host, interactions that are key for the maintenance of homeostasis within this ecosystem. This can lead to the expansion of pathogenic microorga

  2024-07-17

  

  Under some pathological conditions, AT1R internalization is decreased when agonist exposure is prolonged. This weakens or removes the AT1R desensitization effect and leads to AT1R and downstream signal overactivation. AT1R overactivation can result in continued biological effects such as sustained v

  It has been known for a while that oxygenation (the addition of oxygen) of Aβ can inhibit the formation of amyloids and diminish their cytotoxicity. Photo-oxygenation of Aβ started with fullerenes almost a decade ago by Toshima and co-workers. Later, porphyrins and polyoxometalates were used as well

  For the time being, fluorescent in situ hybridization (FISH) remains the ‘gold standard’ for ALK rearrangements diagnosis but immunohistochemistry has become a widely used pre-screening tool and the FDA recently approved the Ventana ALK (D5F3) CDx Assay (Ventana Medical Systems, Tucson, AZ) as a com

  Transparency document Introduction G protein-coupled receptors (GPCRs) comprise a diverse family of seven transmembrane domain-containing receptors represented by over 800 genes in humans. GPCRs respond to a range of stimuli, including peptides, hormones, growth factors, lipids, odorants, and

  Children with ADA-SCID commonly suffer from a variety of opportunistic infections, including viral, fungal, and mycobacterial infections. Due to defects in nkh and IG production, they are also susceptible to infection with encapsulated bacteria such as Haemophilus influenzae, Streptococcus pneumonia

  Ethanol can affect biological systems directly, or also through the interactions between these systems, which become important in the actions promoted by alcohol consumption. Its metabolites acetaldehyde and acetate play a key role in the Acarbose receptor mediating some effects of ethanol (Israel e

  In this study, PRP4 positively regulated MIIP levels and significantly inhibited the invasion of HCT116 cells. Further investigations elucidated that PRP4 dephosphorylated MIIP via PP1A regulation, which was confirmed by PP1A inhibition in the presence of OA. Upon dephosphorylation, MIIP possibly in

  Although experiments on animals and cells indicate that antioxidant and free radical scavenging agents have protective effects against brain damage, the results of preclinical trials are not as encouraging. Edaravone is a type of free radical scavenging drug that was first used as a neuroprotective

  The reaction of 5-LOX with unlabeled AA generated products from hydrogen abstraction at C7 (95% 5-HETE) with minor products derived from abstraction at C10 (5% 8-HETE). With 7,7--AA the selectivity remained skewed towards C7 hydrogen abstraction (59%) compared to C10 hydrogen abstraction products (4
