The mechanism of rotator cuff injury remains to be elucidated. And COX-2 plays a dual role in skeletal muscle injury and regeneration, would be associated with the development of rotator cuff injury. Therefore, we chose human skeletal muscle cells (HSKMC) as an in vitro muscle tissue model and transfected lentivirus with overexpressed COX-2 to simulate the in vitro environment of rotator cuff injury. To investigate the specific molecular biological mechanism of COX-2, transcriptome sequencing (RNA-Seq) was used to analyze the differentially expressed mRNAs in HSKMC overexpressing COX-2. Enrichment analysis was performed to analyze these differentially expressed genes and real-time quantitative PCR (RT-qPCR) was used to examine the mRNA levels of genes induced by overexpression. Subsequently, the role of COX-2 in cell proliferation was confirmed by cell counting kit-8 (CCK-8), and focal adhesion kinase (FAK) and signal transducer and activator of transcription 3 (STAT3) phosphorylation induced by COX-2 was utilized by western blotting (WB). The results showed that total of 30,759 differentially expressed genes were obtained, and the expression of CYP4F3 and GPR87 was significantly increased. COX-2 could bind CYP4F3 and GPR87 and co-localize with them in the cytoplasm. Finally, COX-2 promoted the proliferation of human skeletal muscle cells by activating the FAK and STAT3 pathways.

The effective treatment of inflammatory diseases, particularly their chronic forms, is a key task of modern medicine. Herein, we report the synthesis and evaluation of biocompatible polymer conjugates based on N-2-(hydroxypropyl)methacrylamide copolymers enabling the controlled release of acetylsalicylic acid (ASA)-based anti-inflammatory drugs under specific stimuli. All polymer nanotherapeutics were proposed as water-soluble drug delivery systems with a hydrodynamic size below 10 nm ensuring suitability for the parenteral application and preventing opsonization by the reticuloendothelial system. The nanotherapeutics bearing an ester-bound ASA exhibited long-term release of the ASA/salicylic acid mixture, while the nanotherapeutics carrying salicylic acid hydrazide (SAH) ensured the selective release of SAH in the acidic inflammatory environment thanks to the pH-sensitive hydrazone bond between the polymer carrier and SAH. The ASA- and SAH-containing nanotherapeutics inhibited both cyclooxygenase isoforms and/or the production of pro-inflammatory mediators. Thanks to their favorable design, they can preferentially accumulate in the inflamed tissue, resulting in reduced side effects and lower dosage, and thus more effective and safer treatment.

Mitochondrial oxidative phosphorylation (OXPHOS) fuels cellular ATP demands. OXPHOS defects lead to severe human disorders with unexplained tissue specific pathologies. Mitochondrial gene expression is essential for OXPHOS biogenesis since core subunits of the complexes are mitochondrial-encoded. COX14 is required for translation of COX1, the central mitochondrial-encoded subunit of complex IV. Here we describe a COX14 mutant mouse corresponding to a patient with complex IV deficiency. COX14M19I mice display broad tissue-specific pathologies. A hallmark phenotype is severe liver inflammation linked to release of mitochondrial RNA into the cytosol sensed by RIG-1 pathway. We find that mitochondrial RNA release is triggered by increased reactive oxygen species production in the deficiency of complex IV. Additionally, we describe a COA3Y72C mouse, affected in an assembly factor that cooperates with COX14 in early COX1 biogenesis, which displays a similar yet milder inflammatory phenotype. Our study provides insight into a link between defective mitochondrial gene expression and tissue-specific inflammation.

The objective of this study was to evaluate whether RSV inhibits neutrophil extracellular traps (NETs) that induce joint hyperalgesia in C57BL/6 mice after adjuvant-induced arthritis. A subplantar injection of Freund's complete adjuvant was administered to C57BL/6 mice on day 0 for immunization in the AIA model. Resveratrol (RSV, 25 mg/kg) was administered intraperitoneally once daily starting on day 22 and continuing for two weeks. The effects of mechanical hyperalgesia and edema formation have been assessed in addition to histopathological scoring. Mice were sacrificed on day 35 to determine cytokine levels and PADI4 and COX-2 expression levels. ELISA was used to quantify neutrophil extracellular traps (NETs) along with neutrophil elastase-DNA and myeloperoxidase-DNA complexes in neutrophils. An immunohistochemical stain was performed on knee joints to determine the presence of nuclear factor kappa B p65 (NF-kappaB p65). AIA mice were found to have higher levels of NET in joints and their joint cells demonstrated an increased expression of the PADI4 gene. Treatment with RSV in AIA mice (25 mg/kg, i.p.) significantly (P<0.05) inhibited joint hyperalgesia, resulting in a significant increase in mechanical threshold, a decrease in articular edema, a decrease in the production of inflammatory cytokines, increased COX-2 expression, and a decrease in the immunostaining of NF-kappaB. Furthermore, treatment with RSV significantly reduced the amount of neutrophil elastase (NE)-DNA and MPO-DNA complexes, which were used as indicators of NET formation (P<0.05). This study indicates that RSV reduces NET production and hyperalgesia by reducing inflammation mediated by PADI4 and COX-2. According to these data, NETs contribute to joint pain and resveratrol can be used to treat pain in RA through this pathway.

Neurozánět hraje důležitou roli v patogenezi epilepsie, a proto je nutné objasnit vliv klasických antiepileptik i adjuvantních látek (např. srdečního glykosidu digoxinu, který již dříve vykazoval jasný antikonvulzivní potenciál) na dráhu cyklooxygenázy a neuron-specifické enolázy v podmínkách chronické epileptogeneze. Cílem článku bylo objasnit vliv digoxinu, natrium-valproátu a celekoxibu samostatně, ale i kombinace digoxinu s natrium-valproátem na obsah cyklooxygenázy 1. a 2. typu, prostaglandinů E2, F2α, I2, tromboxanu B2, 8-isoprostanu a neuron-specifické enolázy v mozku myší na modelu pentylenetetrazolem podnícených záchvatů. Bylo zjištěno, že pouze kombinace natriumvalproátu s digoxinem poskytuje úplný ochranný účinek (absence záchvatů) a vykazuje nejzřetelnější vliv na markery neurozánětu a poškození neuronů ve srovnání s monoterapií každým z těchto léčiv a celekoxibem, který se ukázal jako neúčinné antikonvulzivum. Získané výsledky naznačují, že digoxin je slibným adjuvantním lékem ke klasickým antiepileptikům (především natrium-valproátu) v léčbě epilepsie.
Neuroinflammation plays an important role in the pathogenesis of epilepsy, so it is necessary to clarify the influence of standard antiepileptic drugs as well as adjuvant agents (e.g., cardiac glycoside digoxin, which previously showed a clear anticonvulsant potential) on cyclooxygenase pathway and neuron-specific enolase under the conditions of chronic epileptogenesis. The aim of the article is to determine the effect of digoxin, sodium valproate, and celecoxib per se, as well as the combination of digoxin with sodium valproate on the content of cyclooxygenase 1 and 2 types, prostaglandins E2, F2α, I2, thromboxane B2, 8-isoprostane and neuron-specific enolase in the brain of mice in the pentylenetetrazole-induced kindling model. It was found that only the combination of sodium valproate with digoxin provides a complete protective effect (absence of seizures) and shows the clearest influence on neuroinflammation markers and neuronal damage than monotherapy with each of these drugs and celecoxib, which appeared to be an ineffective anticonvulsant. The obtained results indicate that digoxin is a promising adjuvant drug to classical antiepileptic drugs (mostly sodium valproate) in epilepsy treatment.c

Hlavním cílem tohoto článku je prezentovat výsledky syntézy nových alkylových derivátů 5-(2-brom-4-fluorfenyl)-4-ethyl-4H-1,2,4-triazol-3-thiolu a molekulárního dokování studie proti COX-1 a COX-2. Předchozí studie prokázaly široký rozsah biologické aktivity 1,2,4-triazolových derivátů. Proto bylo důležité zjistit, jak nová řada 1,2,4-triazolových derivátů poskytne potenciální protizánětlivou aktivitu. K dosažení cíle byly připraveny alkylové deriváty 5-(2-brom-4-fluorfenyl)-4-ethyl-4H-1,2,4-triazol-3-thiolů (2a-2i) z 5-(2Byl získán brom-4-fluorfenyl)-4-ethyl-4H-l,2,4-triazol-3-thiol (1e). Struktura syntetizovaných sloučenin byla potvrzena 1H-NMR elementární analýzou. Totožnost a čistota sloučenin byla potvrzena metodou kapalinové chromatografie-hmotnostní spektrometrie. Tyto sloučeniny mají relativně jednoduché schéma syntézy, což jim dává výhodu v procesu tvorby potenciálního léčiva a výskyt alkylových radikálů v molekule by měl mít pozitivní vliv na farmakokinetické ukazatele, stabilitu, selektivitu a biologickou dostupnost. U syntetizovaných sloučenin byla provedena studie in silico, konkrétně molekulární dokování týkající se interakce s COX-1 a COX-2. Na základě indexů selektivity vazebných režimů pozorovaných pro vybrané sloučeniny (2e, 2g) s aktivními místy COX1 bylo zjištěno, že sloučeniny mohou pravděpodobně uplatňovat svůj protizánětlivý účinek cestou biosyntézy prostaglandinů, inhibicí COX-1 místo COX-2. Rovněž byl prokázán vliv hydrofobních interakcí alkylových skupin 1,2,4-triazolových derivátů na změnu afinity a selektivity k COX-1 nebo COX-2. Proto jsou deriváty 1,2,4 slibnými kandidáty na zlepšení, další studium a budoucí vývoj nových, účinnějších protizánětlivých léčiv pro terapeutické použití.
The main goal of this article is to present the results of the synthesis of new alkyl derivatives of 5-(2-bromo4-fluorophenyl)-4-ethyl-4H-1,2,4-triazole-3-thiol and molecular docking studies against COX-1 and COX-2. Previous studies have established a wide range of biological activity of 1,2,4-triazole derivatives. Therefore, it was essential to determine how a new series of 1,2,4-triazole derivatives would provide potential anti-inflammatory activity. To reach the goal, raw alkyl derivatives of 5-(2-bromo-4-fluorophenyl)-4-ethyl-4H-1,2,4-triazole-3-thiols (2a-2i) from 5-(2-bromo-4-fluorophenyl)-4-ethyl-4H-1,2,4-triazole3-thiol (1e) were obtained. The structure of the synthesized compounds was confirmed by 1H-NMR elemental analyses. The individuality and purity of compounds were confirmed by the method of liquid chromatography-mass spectrometry. These compounds have a relatively simple synthesis scheme, which gives them an advantage in creating a potential drug, and the appearance of alkyl radicals in the molecule should positively affect pharmacokinetic indicators, stability, selectivity, and bioavailability. An in silico study was conducted for the synthesized compounds, namely molecular docking, in relation to the interaction with COX-1 and COX-2. Based on the selectivity indexes of binding modes observed for the selected compounds (2e, 2g) with active COX-1 centers, it was found that compounds can reliably exhibit their anti-inflammatory effect through the prostaglandin biosynthesis pathway, inhibiting COX-1 instead of COX-2. The effect of hydrophobic interactions of alkyl groups of 1,2,4-triazole derivatives on changes in affinity and selectivity to COX-1 or COX-2 has also been proven. Therefore, derivatives of 1,2,4 are promising candidates for improvement, further study, and future development of new, more powerful antiinflammatory drugs for therapeutic use.
AIMS: The effect of polyphenolic fraction of Lonicera caerulea (PFLC) and alkaloid fraction of Macleaya cordata (AFMC) mix on the production of inflammatory mediators in human gingival fibroblasts pretreated with lipopolysaccharide (LPS) was investigated. In addition, protective effects of mucoadhesive paste containing combination of PFLC and AFMC (0.05% and 0.01%, respectively; n=15, Group A) and placebo (n=15, Group B) were evaluated in patients after surgical extraction of lower third molars. METHODS: Gingival fibroblasts were pre-treated with LPS (10 μg/mL; 24 h) and PFLC/AFMC (25/0.25; 50/0.25; 100/0.25; 25/0.5; 50/0.5; 100/0.5 μg/mL) in serum-free medium was applied for 4 h. Then the interleukin-6 (IL-6), reactive oxygen species (ROS) generation, level of intracellular glutathione (GSH) and expression of cyclooxygenase-2 (COX-2) were evaluated. The study was a 6-day, single-center, randomized, double-blind and placebo-controlled trial consisting of two parallel treatment arms. A modified Oral health impact profile questionnaire including both general oral condition and extraction related questions, was used to evaluate the oral condition and other changes before (day 0) and on the days 1, 3 and 6 after surgical extraction. RESULTS AND CONCLUSION: The combination of PFLC with AFMC caused a reduction of ROS generation, reduced IL-6 production and suppressed the expression of COX-2. In group A the paste treatment contributed to improvement of oral health-related quality of life. Topical application of PFLC and AFMC into the extraction wound improved post-extraction site wound healing probably by antioxidant and anti-inflammatory mechanisms.

It was suggested that impaired β-adrenergic relaxation in spontaneously hypertensive rats (SHR) might contribute to their high blood pressure (BP). Our study was focused on isoprenaline-induced dilatation of conduit femoral or resistance mesenteric arteries and on isoprenaline-induced BP reduction in SHR and Wistar-Kyoto rats (WKY). We confirmed decreased β-adrenergic relaxation of SHR femoral arteries due to the absence of its endothelium-independent component, whereas endothelium-dependent component of β-adrenergic smooth muscle relaxation was similar in both strains. Conversely, isoprenaline-induced relaxation of resistance mesenteric arteries was similar in both strains and this was true for endothelium-dependent and endothelium-independent components. We observed moderately reduced sensitivity of SHR mesenteric arteries to salmeterol (β2-adrenergic agonist) and this strain difference disappeared after endothelium removal. However, there was no difference in mesenteric arteries relaxation by dobutamine (β1-adrenergic agonist) which was independent of endothelium. The increasing isoprenaline doses elicited similar BP decrease in both rat strains, although BP sensitivity to isoprenaline was slightly decreased in SHR. The blockade of cyclooxygenase (indomethacin) and NO synthase (L-NAME) further reduced BP sensitivity to isoprenaline in SHR. On the other hand, salmeterol elicited similar BP decrease in both strains and the blockade of cyclooxygenase and NO synthase increased BP sensitivity to salmeterol in SHR as compared to WKY. In conclusion, attenuated β-adrenergic vasodilatation of conduit arteries of SHR but similar β-adrenergic relaxation of resistance mesenteric arteries from WKY and SHR and their similar BP response to β-adrenergic agonists do not support major role of altered β-adrenergic vasodilatation for high BP in genetic hypertension.

Selective cyclooxygenase (COX)-1 inhibitors can be employed as potential cardioprotective drugs. Moreover, COX-1 plays a key role in inflammatory processes and its activity is associated with some types of cancer. In this work, we designed and synthesized a set of compounds that structurally mimic the selective COX-1 inhibitors, SC-560 and mofezolac, the central cores of which were replaced either with triazole or benzene rings. The advantage of this approach is a relatively simple synthesis in comparison with the syntheses of parent compounds. The newly synthesized compounds exhibited remarkable activity and selectivity toward COX-1 in the enzymatic in vitro assay. The most potent compound, 10a (IC50 = 3 nM for COX-1 and 850 nM for COX-2), was as active as SC-560 (IC50 = 2.4 nM for COX-1 and 470 nM for COX-2) toward COX-1 and it was even more selective. The in vitro COX-1 enzymatic activity was further confirmed in the cell-based whole-blood antiplatelet assay, where three out of four selected compounds (10a,c,d, and 3b) exerted outstanding IC50 values in the nanomolar range (9-252 nM). Moreover, docking simulations were performed to reveal key interactions within the COX-1 binding pocket. Furthermore, the toxicity of the selected compounds was tested using the normal human kidney HK-2 cell line.

NSAID jsou slibné látky pro prevenci poškození chladem (frigoprotektiva). Vliv profylaktického podávání neselektivního inhibitoru COX diklofenaku sodného (7 mg/kg) a vysoce selektivního inhibitoru COX-2 etorikoxibu (5 mg/kg) na biomarkery cyklooxygenázové dráhy byl studován na modelu akutního celkového ochlazení (vzduchová hypotermie při –18 °C po dobu 2 hodin). Diklofenak zcela zabránil poklesu tělesné teploty a předčil etorikoxib. V játrech potkanů byl bezprostředně po expozici chladu mírně zvýšen obsah COX-1, velmi výrazně obsah COX-2, snížena hladina PGE2 a zvýšeny hladiny PGF2α a zejména PGI2 a TXB2. V krevním séru byla hladina COX-1 snížena a změny hladin COX-2 a prostaglandinů byly podobné jako v játrech. Diklofenak působil mírně směrem k normalizaci obou izoforem COX v játrech, mírně zvyšoval obsah PGE2 a snižoval – PGF2α a TXB2, aniž by měnil hladinu PGI2. V séru diklofenak snížil hladinu COX-1 na podnormální hodnoty a jeho účinek na ostatní biomarkery byl podobný jako v játrech, s výjimkou mírného snížení PGI2. Diklofenak byl tedy horší než etorikoxib, který normalizoval COX-1, COX-2, PGE2, PGI2 v játrech, snížil obsah PGF2α a TXB2 v játrech na podnormální hodnoty, zatímco v krevním séru snížil COX-1, COX-2, PGE2 na podnormální hodnoty, normalizoval PGF2α a PGI2, významně snížil TXB2. Opačný stupeň intenzity vlivu diklofenaku a etorikoxibu na cyklooxygenázovou dráhu a tělesnou teplotu svědčí o disociaci protizánětlivé a frigoprotektivní aktivity. Inhibice oxidačního stresu není pro frigoprotektivní aktivitu NSAID rozhodující, protože diklofenak i přes slabší vliv na obsah 8-isoprostanu v játrech stále vykazuje maximální frigoprotektivní aktivitu.
NSAIDs are promising agents for preventing cold injury (frigoprotectors). The influence of prophylactic administration of the non-selective COX inhibitor diclofenac sodium (7 mg/kg) and the highly selective COX-2 inhibitor etoricoxib (5 mg/kg) on cyclooxygenase pathway biomarkers was studied on the model of acute general cooling (air hypothermia at –18 °С for 2 hours). Diclofenac completely prevented a decrease in body temperature, surpassing etoricoxib. In the liver of the rats immediately after cold exposure, the content of COX-1 was increased moderately and the content of COX-2 highly significantly. Very significantly, the level of PGE2 decreased, and the levels of PGF2α, especially PGI2 and TXB2, were elevated. In the blood serum, the level of COX-1 was decreased, and the changes in COX-2 and prostaglandins levels were similar to those in the liver. Diclofenac exerted a moderate effect towards the normalization of both COX isoforms in the liver, moderately increased the content of PGE2, and decreased – PGF2α and TXB2 without changing the level of PGI2. In serum, diclofenac reduced COX-1 level to subnormal values, and its effect on other biomarkers was similar to that in the liver, except for a moderate decrease in PGI2. Thus, diclofenac was inferior to etoricoxib, which normalized COX-1, COX-2, PGE2, and PGI2 in the liver and reduced the content of PGF2α and TXB2 in the liver to subnormal values. At the same time, in the blood serum, it decreased COX-1, COX-2, and PGE2 to subnormal values, normalized PGF2α, and PGI2, and significantly reduced TXB2. The opposite degree of intensity of the influence of diclofenac and etoricoxib on the cyclooxygenase pathway and body temperature indicates a dissociation of anti-inflammatory and frigoprotective activity. Inhibition of oxidative stress is not determinative for the frigoprotective activity of NSAIDs since diclofenac, despite the weaker influence on the content of 8-isoprostane in the liver, still exerts the maximum frigoprotective activity.
