JAK-STAT-dependent regulation of scavenger receptors in LPS-activated murine macrophages.

In atherosclerosis progression, atherosclerotic plaques develop upon accumulated foam cells derived from macrophages that take up modified low-density lipoprotein (LDL). CD36 and CD204 are the principal scavenger receptors responsible for the uptake of modified LDL. Lipopolysaccharide (LPS) exacerbates atherosclerosis by enhancing the expression of scavenger receptors and thus increasing the uptake of modified LDL into macrophages. However, the signaling pathways that mediate LPS and scavenger receptor expr...

Targeting CD52 does not affect murine neuron and microglia function.

The humanized anti-CD52 antibody alemtuzumab is successfully used in the treatment of multiple sclerosis (MS) and is thought to exert most of its therapeutic action by depletion and repopulation of mainly B and T lymphocytes. Although neuroprotective effects of alemtuzumab have been suggested, direct effects of anti-CD52 treatment on glial cells and neurons within the CNS itself have not been investigated so far. Here, we show CD52 expression in murine neurons, astrocytes and microglia, both in vitro and in...

MicroRNA-708 represses hepatic stellate cells activation and proliferation by targeting ZEB1 through Wnt/β-catenin pathway.

Liver fibrosis is caused by a sustained wound healing response to chronic liver injury, and the activation of insubstantial hepatic stellate cells (HSCs) is the key process involved. The progression of liver fibrosis may be attenuated by suppressing activation and proliferation of the HSCs. MicroRNA (miRNA) have emerged as major players in governing fundamental biological processes through multiple mechanisms MiR-708 is known to inhibit the development of hepatocellular carcinoma. However, whether miR-708 c...

Protective effects of Erdosteine on interleukin-1β-stimulated inflammation via inhibiting the activation of MAPK, NF-κB, and Wnt/β-catenin signaling pathways in rat osteoarthritis.

Osteoarthritis (OA), a degenerative arthropathy, is featured with progressive degradation of cartilage and a chondrocyte inflammatory response. Erdosteine (ER) showed the anti-oxidant properties and various anti-inflammatory effects in various diseases. However, whether it protects against OA remains unknown. In this study, we explore the potential therapeutic properties of ER on IL-1β-stimulated rat chondrocytes and its underlying mechanism in vitro and vivo. Cell viability, pro-inflammatory cytokines and...

Anticancer activities of fatty acids and their heterocyclic derivatives.

Traditional chemotherapy relies on the premise that rapidly proliferating cancer cells are more likely to be killed by a cytotoxic agent, but in reality, the long-standing problem of chemotherapy is the lack of tumor-specific treatments. Apart from the impact on tumor cells, the drugs' major limitation is their severe adverse side effects on normal cells and tissues. Nutritional and epidemiological studies have indicated that cancer progression is correlated with the consumption of fatty acids, but the exac...

The role of circadian clock gene BMAL1 in vascular proliferation.

Brain and muscle Arnt-like protein-1 (BMAL1), a component of the molecular clock, is implicated in the development of cardiovascular diseases, including atherosclerosis and abdominal aortic aneurysms. However, the role of BMAL1 in vascular proliferation associated with vascular remodeling is unknown. In the present study, we investigated the mechanisms underlying BMAL1 expression in vascular smooth muscle cells (VSMCs) and the role of BMAL1 in VSMC proliferation. BMAL1 expression significantly increased in ...

Neurodegenerative diseases affect millions of people around the world. Several studies point out caspase-3 as a key player in the development and progression of neurological disorders including amyotrophic lateral sclerosis, Alzheimer's, Parkinson's and Huntington's diseases. Furthermore, oxidative stress and mitochondrial dysfunction plays an important role in neurodegenerative pathologies leading to neuronal damage and cell death. Pharmacological properties of nitrones such as free radical trapping and ne...

Intracerebroventricular administration of CYX-6, a potent μ-opioid receptor agonist, a δ- and κ-opioid receptor antagonist and a biased ligand at μ, δ & κ-opioid receptors, evokes antinociception with minimal constipation and respiratory depression in rats in contrast to morphine.

Mu opioid receptor (MOPr) agonists are thought to produce analgesia via modulation of G-protein-coupled intracellular signalling pathways whereas the β-arrestin2 pathway is proposed to mediate opioid-related adverse effects. Here, we report the antinociception, constipation and respiratory depressant profile of CYX-6, a potent MOPr agonist that is also a delta and a kappa opioid receptor (DOPr/KOPr) antagonist and that lacks β-arrestin2 recruitment at each of the MOPr, DOPr and the KOPr. In anaesthetised ...

α-Lipoic acid prevents the ionizing radiation-induced epithelial-mesenchymal transition and enhances the radiosensitivity in breast cancer cells.

Radiotherapy is routinely used in the treatment of breast cancer. However, its efficiency is often limited by the development of radioresistance and metastasis. The cancer cells surviving irradiation show epithelial-mesenchymal transition (EMT) along with increased migration, invasion and metastasis. In this study, we have evaluated the role of α-lipoic acid in preventing the radiation-induced EMT and in sensitizing the breast cancer cells to radiation. The breast cancer cell lines, MCF-7 and MDA-MB-231 we...

Urolithin B improves cardiac function and reduces susceptibility to ventricular arrhythmias in rats after myocardial infarction.

Cardiac fibrosis and inflammation play critical roles in ventricular remodelling after myocardial infarction (MI). Urolithin B (UB), a metabolite of ellagitannin-rich foods, has various biological activities, but its effect on ventricular remodelling after MI has not been determined. The present study evaluated whether UB inhibited ventricular structural remodelling and decreased the occurrence of ventricular arrhythmias after MI. Sprague-Dawley (SD) rats underwent ligation of the left anterior descending c...

LINC00473 inhibits vascular smooth muscle cell viability to promote aneurysm formation via miR-212-5p/BASP1 axis.

Abdominal aortic aneurysm (AAA), as the most common type of aortic aneurysm, is closely related to the proliferation and apoptosis ability of vascular smooth muscle cells (VSMCs). Long non-coding RNAs (lncRNAs) are emerging regulators in disease development. LncRNA LINC00473 has been shown to affect cell proliferation and apoptosis in various cancers, but its role in AAA is still blank. In this work, in vitro AAA models were successfully established since cell viability was inhibited whereas apoptosis stimu...

In vitro characterization of the thermoneutral transient receptor potential vanilloid-1 (TRPV1) inhibitor GRTE16523.

The TRPV1 ion channel is a neuronal sensor that plays an important role in nociception and neuropathic as well as inflammatory pain. In clinical trials, hyperthermia and thermo-hypoaesthesia turned out as major side effects of TRPV1 antagonists, preventing successful development of such molecules as analgesics. In vitro studies demonstrated that the TRPV1 ion channel is a polymodal sensor integrating stimuli from molecular modulators with temperature, pH and transmembrane potential. Temperature dependent ga...

TGFαL3-SEB fusion protein as an anticancer against ovarian cancer.

TGFαL3-SEB is a new synthetic fusion protein produced by the combination of the third loop of transforming growth factor with staphylococcal enterotoxin type B. In the current study, the anti-tumor effects of TGFαL3-SEB were evaluated against SKOV3 cells, which highly expressed the epidermal growth factor receptor (EGFR). Our findings showed that incubation of SKOV3 cells with 75, 100 and 150 μg/ml of TGFαL3-SEB significantly reduces the proliferation rate in a concentration-dependent manner (P 

Yohimbine ameliorates lipopolysaccharide-induced acute kidney injury in rats.

Sepsis-induced acute kidney injury (AKI) is frequently observed in the intensive care unit. We previously revealed that yohimbine, an α-adrenoceptor antagonist, has protective effects on renal ischemia/reperfusion injury-induced AKI in rats. This study aimed to investigate the renoprotective effect of yohimbine on lipopolysaccharide (LPS)-induced AKI in rats. Male Sprague Dawley rats were randomly divided into the following groups: Sham-operated group, LPS (10 mg/kg, i.p.) and LPS + yohimbine (0.1 or 0....

Fibroblast growth factor homologous factors are potential ion channel modifiers associated with cardiac arrhythmias.

Stable electrical activity in cardiac myocytes is the basis of maintaining normal myocardial systolic and diastolic function. Cardiac ionic currents and their associated regulatory proteins are crucial to myocyte excitability and heart function. Fibroblast growth factor homologous factors (FHFs) are intracellular noncanonical fibroblast growth factors (FGFs) that are incapable of activating FGF receptors. The main functions of FHFs are to regulate ion channels and influence excitability, which are processes...

The muscarinic receptor antagonist tolterodine inhibits voltage-dependent K channels in rabbit coronary arterial smooth muscle cells.

We explored the effect of the muscarinic receptor antagonist tolterodine on voltage-dependent K (Kv) channels using the patch-clamp technique in coronary arterial smooth muscle cells freshly isolated from rabbits. Tolterodine inhibited Kv channels in a concentration-dependent manner, with an IC of 1.71 ± 0.33 μM and Hill coefficient of 0.69 ± 0.03. Tolterodine accelerated the decay rate of Kv channel inactivation. The apparent rate constants of association and dissociation for tolterodine were ...

Natural alkaloid and polyphenol compounds targeting lipid metabolism: Treatment implications in metabolic diseases.

Once the balance between lipid anabolism and catabolism is broken, metabolic disorder will occur in the organism and finally lead to metabolic diseases, such as nonalcoholic fatty liver disease (NAFLD), obesity and cancer. No established therapeutic regimens for treating NAFLD and obesity exist yet. Many natural compounds are extracted from botany, fungi and marine organisms. Importantly, natural compounds are major sources of innovative medicine. In this review, we first elucidate the important roles of li...

Salvianolic acid B regulates macrophage polarization in ischemic/reperfused hearts by inhibiting mTORC1-induced glycolysis.

Macrophages play important roles in the healing and remodeling of cardiac tissues after myocardial ischemia/reperfusion (MI/R) injury. Here we investigated the potential effects of salvianolic acid B (SalB), one of the abundant and bioactive compounds extracted from Chinese herb Salvia Miltiorrhiza (Danshen), on macrophage-mediated inflammation after MI/R and the underlying mechanisms. In primary cultured bone marrow-derived macrophages (BMDMs), SalB attenuated lipopolysaccharide (LPS)-induced M1 biomarkers...

The intraperitoneal administration of MOTS-c produces antinociceptive and anti-inflammatory effects through the activation of AMPK pathway in the mouse formalin test.

The activation of the AMP activated protein kinase (AMPK) exerts antinociceptive effects in acute and neuropathic pain models. Mitochondrial open-reading-frame of the twelve S rRNA-c (MOTS-c), a mitochondrial-derived peptide, regulates many biological activities via activating AMPK. However, the role of MOTS-c in the formalin-induced inflammatory nociception remains unclear. In this study, we investigated the role of MOTS-c in the formalin-induced inflammatory nociception. The antinociceptive effect of MOTS...

Ondansetron, a highly selective 5-HT receptor antagonist, reduces L-DOPA-induced dyskinesia in the 6-OHDA-lesioned rat model of Parkinson's disease.

L-3,4-dihydroxyphenylalanine (L-DOPA) has been the standard treatment for Parkinson's disease (PD), despite that its chronic use leads to motor fluctuations and dyskinesia in as many as 95% of patients. Previous studies have shown that serotonin type 3 (5-HT) receptor blockade reduces dopamine levels within the striatum, suggesting that it could potentially lead to a reduction of dyskinesia. Here, we assessed the effects of ondansetron on L-DOPA-induced abnormal involuntary movements (AIMs) in the 6-hydroxy...

Estrogenic and anti-inflammatory effects of pseudoprotodioscin in atherosclerosis-prone mice: Insights into endothelial cells and perivascular adipose tissues.

Pseudoprotodioscin (PPD), a phytoestrogen isolated from Dioscorea nipponica Makino, is recognized to possess anti-inflammatory and antiadipogenic capacities. However, little is known about the antiatherosclerotic effects of PPD and the underlying mechanisms. Here, the contribution of estrogen receptors (ERs) and inflammation to PPD-mediated amelioration of endothelial dysfunction has been fully assessed. PPD administration alleviated atherosclerotic lesions by lowering total cholesterol in ovariectomized ap...

Thymosin beta 4 attenuates PrP(106-126)-induced human brain endothelial cells dysfunction.

The blood-brain barrier (BBB) is a highly selective permeability barrier that separates the circulating blood from the brain and extracellular fluid in the central nervous system (CNS). The BBB is formed by cerebral endothelial cells connected by tight junctions. Prion diseases are neurodegenerative pathologies characterized by the accumulation of altered forms of the prion protein (PrP), named PrP. Thymosin beta 4 (Tβ) is an actin-sequestering peptide known to bind monomeric actin and inhibit its polymeri...
