Lipid raft is an important element for the cellular entry of some viruses, including coronavirus infectious bronchitis virus (IBV). However, the exact role of lipid rafts in the cellular membrane during the entry of IBV into host cells is still unknown. In this study, we biochemically fractionated IBV-infected cells via sucrose density gradient centrifugation after depleting plasma membrane cholesterol with methyl-β-cyclodextrin or Mevastatin. Our results demonstrated that unlike IBV non-structural proteins, IBV structural proteins co-localized with lipid raft marker caveolin-1...

Excessive alcohol uptake exerts hepatocellular toxicity, ultimately leading to multiple liver diseases such as steatohepatitis and liver cirrhosis. Here, we aimed to explore the effects of mulberry leaf extract (MLE) and its major components chlorogenic acid (CGA) and neochlorogenic acid (nCGA) on alcoholic steatohepatitis. We determined the composition of MLE using liquid chromatography-mass spectrometric (LC-MS) analysis, which showed that MLE consisted of mainly chlorogenic acid derivatives and other polyphenols...

Bisphenol A (BPA), a typical environmental endocrine-disrupting chemical, induces epigenetic inheritance. Whether histone acetylation plays a role in these effects of BPA is largely unknown. Here, we investigated histone acetylation in male rats after long-term exposure to a 'safe' dose of BPA. Twenty adult male rats received either BPA (50 μg/kg·bw/day) or a vehicle diet for 35 weeks. Decreased protein lysine-acetylation levels at approximately ~17 kDa and ~25 kDa, as well as decreased histone acetylation of H3K9, H3K27 and H4K12, were detected by Western blot analysis of testes from the treated rats compared with controls...

Recent evidence suggests that β-arrestins, which are involved in G protein-coupled receptors desensitization, may influence mechanotransduction. Here, we observed that nitric oxide (NO) production was abrogated in human saphenous vein endothelial cells (SVECs) transfected with siRNA against β-arrestin 1 and 2 subjected to shear stress (SS, 15 dynes/cm(2), 10 min). The downregulation of β-arrestins 1/2 in SVECs cells also prevented the SS-induced rise in levels of phosphorylation of Akt and endothelial nitric oxide synthase (eNOS, Serine 1177)...

BACKGROUND: Nanotechnology is a science that involves imaging, measurement, modeling and a manipulation of matter at the nanometric scale. One application of this technology is drug delivery systems based on nanoparticles obtained from natural or synthetic sources. An example of these systems is synthetized from poly(3-hydroxybutyrate-co-3-hydroxyvalerate), which is a biodegradable, biocompatible and a low production cost polymer. The aim of this work was to investigate the uptake mechanism of PHBV nanoparticles in two different epithelial cell lines (HeLa and SKOV-3)...

BACKGROUND: We previously demonstrated that endothelial microparticles (EMPs) are increased in mitral valve diseases and impair valvular endothelial cell function. Perioperative systemic inflammation is an important risk factor and complication of cardiac surgery. In this study, we investigate whether EMPs increase in congenital heart diseases to promote inflammation and endothelial dysfunction. METHODS: The level of plasma EMPs in 20 patients with atrial septal defect (ASD), 23 patients with ventricular septal defect (VSD), and 30 healthy subjects were analyzed by flow cytometry...

Vitamin D plays a pivotal role to maintain skeletal muscle integrity and health. Vitamin D deficiency characterizes inflammatory myopathy (IM) and diabetes, often overlapping diseases involving skeletal muscle damage. Vitamin D receptor (VDR) agonists likely exert beneficial effects in both IM and metabolic disturbances. We aim to evaluate in vitro the effect of elocalcitol, a non-hypercalcemic VDR agonist, on the biomolecular metabolic machinery of human skeletal muscle cells (Hfsmc), vs. insulin (I). We analyzed GLUT4, Flotillin-1, Caveolin-3 and Caveolin-1 cell expression/localization; mTOR, AKT, ERK and 4E-BP1 phosphorylation; IL-6 myokine release; VDR expression...

AIMS: Activation of CaMKII induces a myriad of biological processes and plays dominant roles in cardiac hypertrophy. Caveolar microdomain contains many CaMKII targets, including L-type Ca2+ channel (LTCC) complex, and serves as a signalling platform. The location of CaMKII activation is thought to be critical, however, the roles of CaMKII in caveolae are still elusive due to lack of methodology for the assessment of caveolae-specific activation. Our aim was to develop a novel tool for the specific analysis of CaMKII activation in caveolae, and to determine the functional role of caveolar CaMKII in cardiac hypertrophy...

Dozens of murine models of indolent and aggressive B-cell lymphomas have been generated to date. These include those manifesting chronic lymphocytic leukemia (CLL), diffuse large B-cell lymphoma (DLBCL), as well as xenografts of mantle cell lymphoma (MCL). These models have led to an improved understanding of disease etiology, B-cell biology, immunomodulation, and the importance of the tumor microenvironment. Despite these efforts in CLL, DLBCL, and MCL, considerably little progress toward a model of splenic marginal zone lymphoma (SMZL) has been accomplished...

Salvianolic acid A (Sal A), a bioactive compound isolated from the Chinese medicinal herb Danshen, is used for the prevention and treatment of cardiovascular diseases. However, the protective function of Sal A on preserving the role of blood-spinal cord barrier (BSCB) after spinal cord injury (SCI) is unclear. The present study investigated the effects and mechanisms of Sal A (2.5, 5, 10 mg/kg, i.p.) on BSCB permeability at different time-points after compressive SCI in rats. Compared to the SCI group, treatment with Sal A decreased the content of the Evans blue in the spinal cord tissue at 24 h post-SCI...

The mechanisms underlying propofol's cardioprotective role remain elusive. Caveolin-3 (Cav-3) has been shown to mediate both opioids- and volatile anesthetics-induced cardioprotection against ischemia/reperfusion (I/R) injury. We hypothesize that the cardioprotective role of propofol is mediated through Cav-3 and its regulation of PI3K/Akt/GSK3β signal pathway. Rats or H9c2 cardiomyocytes were exposed to propofol prior to I/R or simulated ischemia/reperfusion (SI/R). Propofol pretreatment significantly decreased left ventricle (LV) infarct size in vivo (P < 0...

Obliterative bronchiolitis is the primary noninfectious pulmonary complication after allogeneic hematopoietic cell transplantation and the only pathognomonic manifestation of pulmonary chronic graft-versus-host disease (cGVHD). In our recent study, we identified a novel effect of IL-26, which is absent in rodents, on transplant related-obliterative bronchiolitis. Sublethally irradiated NOD/Shi-scidIL2rγnull mice transplanted with human umbilical cord blood gradually exhibited obliterative bronchiolitis with increased collagen deposition and predominant infiltration with human IL-26+CD26+CD4 T cells...

OBJECTIVES: Percutaneous coronary interventions (PCIs) save countless acute myocardial infarction (AMI) patients. However, endothelial injury is still a inevitable complication. Circulating microparticles (MPs) play important roles in vascular dysfunction. Whether PCI affects function of MPs remains unclear. METHODS: MPs were obtained from AMI patients (n = 38) both preoperatively and 24 hours after PCI, and healthy subjects (n = 20). MPs origins were tested by flow cytometry...

Dexmedetomidine (DXM) is a selective α2-adrenoceptor (α2‑AR) and imidazoline receptor (IR) agonist that has been reported to regulate inflammatory responses mediated by diverse signaling pathways through α2‑AR. The majority of the reported receptors or downstream molecules have been demonstrated to locate with caveolin‑1, a protein suggested to participate in regulating Toll‑like receptor 4 (TLR4)‑mediated inflammatory responses and the pathogen endocytosis capability of macrophages. The present study hypothesized that DXM may influence these pathways by regulating the expression of caveolin‑1 and mediating the subsequent effects...

The processes causing increased hepatic triglycerides (TGs) in mouse models of hepatic steatosis (HS) due to high fat diet (HFD)-induced obesity (DIO), EtOH consumption, or obesity mutations (ob/ob, db/db) are uncertain. This report summarizes two studies. Study 1 focused on regulation by five transcription factors (TFs) (NfKb, Srebp-lc, AMPK, PPARα, PPARγ) of seven, much-studied hepatic long-chain fatty acid (LCFA) transporters (FABPpm, CD36, FATPl, FATP2, FATP4, FATP5, & Caveolin-1 [CAV-1]), and expression of genes for enzymes of LCFA synthesis (SCD-1, FASN) in mice with HS from various causes...

To increase the encapsulation efficiency and oral absorption of doxorubicin hydrochloride (DOX), a novel drug delivery system of enoxaparin sodium-PLGA hybrid nanoparticles (EPNs) was successfully designed. By introducing the negative polymer of enoxaparin sodium (ES) to form an electrostatic complex with the cationic drug, DOX, the encapsulation efficiency (93.78%) of DOX was significantly improved. The X-ray diffraction (XRD) results revealed that the DOX-ES complex was in an amorphous form. An in vitro release (pH6...

BACKGROUND AND AIMS: Caveolin-1 (CAV1) is a multifunctional scaffolding protein and plays an important role in tumorigenesis. However, the epigenetic changes of CAV1 in gastric cardia adenocarcinoma (GCA) have not been investigated so far. The purpose of this study was to clarify the contribution of critical CpG sites in CAV1 to progression/prognosis of GCA and to further elucidate the effect of critical CpG sites on the ectopic expression of β-catenin in GCA. METHODS: Methylation-specific polymerase chain reaction (MSP) and bisulfite genomic sequencing (BGS) methods were, respectively, applied to examine the methylation status of CAV1...
