Leptin and hypoxia are pro-fibrotic factors involved in fibrogenesis, however, the gene expression profiles remain to be fully elucidated. The aim of the present study was to investigate the regulatory roles of leptin and hypoxia on the L929 mouse fibroblast cell line. The cells were assigned to a normoxia, normoxia with leptin, hypoxia, and hypoxia with leptin group. The cDNA expression was detected using an Agilent mRNA array platform. The differentially expressed genes (DEGs) in response to leptin and hypoxia were identified using reverse transcription‑quantitative polymerase chain reaction analysis, followed by clustering analysis, Gene Ontology analysis and pathway analysis...

Fatty acid amides (FAAs), conjugates of fatty acids with ethanolamine, mono-amine neurotransmitters or amino acids are a class of molecules that display diverse functional roles in different cells and tissues. Recently we reported that one of the serotonin-fatty acid conjugates, docosahexaenoyl serotonin (DHA-5-HT), previously found in gut tissue of mouse and pig, attenuates the IL-23-IL-17 signaling axis in LPS-stimulated mice macrophages. However, its presence and effects in humans remained to be elucidated...

Sea turtle fibropapillomatosis (FP) is a disease marked by proliferation of benign but debilitating cutaneous and occasional visceral tumours, likely to be caused by chelonid alphaherpesvirus 5 (ChHV5). This study presents a phylogeny of ChHV5 strains on the east coast of Queensland, Australia and a validation for previously unused primers. Two different primer sets (gB-1534 and gB-813) were designed to target a region including part of the UL27 glycoprotein B (gB) gene and part of UL28 of ChHV5. Sequences obtained from FP tumours on juvenile green turtles (<65 cm CCL) had substantial homology with published ChHV5 sequences while a skin biopsy from a turtle without FP failed to react in the PCRs used in this study...

Objective: The traditional Chinese medicine Anluohuaxianwan (ALHXW) has been used to treat liver fibrosis induced by chronic hepatitis B virus (HBV) infection. However, the anti-fibrosis mechanisms of ALHXW remain to be investigated. This study used a rat model of carbon tetrachloride (CCl(4))-induced liver fibrosis to explore the potential antifibrogenic mechanisms of ALHXW. Methods: Twenty-seven male Wistar rats were randomly assigned to control group, model group, and treatment group (n = 9 per group). Rats in the model and treatment group were injected intraperitoneally with 40% CCl(4)(2 ml/kg), and rats in the control group were administered saline twice a week for 6 weeks...

BACKGROUND: Patients with severe asthma appear relatively corticosteroid resistant. Corticosteroid responsiveness is closely related to the degree of eosinophilic airway inflammation. The extent to which eosinophilic airway inflammation in severe asthma responds to treatment with systemic corticosteroids is not clear. OBJECTIVE: To relate the physiological and inflammatory response to systemic corticosteroids in asthma to disease severity and the baseline extent of eosinophilic inflammation...

Species of the genus Laserpitium have been used traditionally to treat inflammation and infection. From the herb of Laserpitium zernyi, six new compounds were isolated and their structures elucidated (using IR, NMR, HRMS data) as derivatives of 8-daucene-2,4,10-triol (1, 2, and 4), 7-daucene-2,4,10-triol (3), a lapiferin derivative featuring a C-2 ester moiety (5), and a daucane featuring an exomethylene group at C-8 (6). Also isolated were the rare daucanes vaginatin (7) and laserpitin (8). In a search for selective glucocorticoid receptor (GR) modulators, the compounds were tested for their capacity to inhibit NF-κB and AP-1 pro-inflammatory factors and for a potential competitive effect on a dexamethasone (Dex)-induced GR-driven glucocorticoid response element (GRE) reporter gene...

Chemokines play an important role in the pathophysiology of dermatomyositis (DM) with interstitial pneumonia (IP). However, the relation between chemokines and the disease activity or prognosis of DM-IP has not been elucidated. We evaluated the serum C-C motif chemokine ligand (CCL) 2, Th1 chemokines (C-X-C motif chemokine ligand [CXCL] 9, CXCL10, CXCL11), and Th2 chemokine (CCL17) profiles of 30 patients, and examined the relation between these chemokines and the disease activity or prognosis of DM-IP. Initial serum CCL2 level was higher in the death group (P = 0...

BACKGROUND: Neuroimmune mechanisms have been linked to the pathophysiology of bipolar disorder based on studies of biomarkers in plasma, cerebrospinal fluid (CSF), and postmortem brain tissue. There are, however, no longitudinal studies investigating if CSF markers of neuroinflammation and neuronal injury predict clinical outcomes in patients with bipolar disorder. We have in previous studies found higher CSF concentrations of interleukin-8 (IL-8), monocyte chemoattractant protein 1 (MCP-1/CCL-2), chitinase-3-like protein 1 (CHI3L1/YKL-40), and neurofilament light chain (NF-L) in euthymic patients with bipolar disorder compared with controls...

Marine molluscs are rich in biologically active natural products that provide new potential sources of anti-inflammatory agents. Here we used bioassay guided fractionation of extracts from the muricid Dicathais orbita to identify brominated indoles with anti-inflammatory activity, based on the inhibition of nitric oxide (NO) and tumour necrosis factor α (TNFα) in lipopolysaccharide (LPS) stimulated RAW264.7 macrophages and prostaglandin E2 (PGE2) in calcium ionophore-stimulated 3T3 ccl-92 fibroblasts. Muricid brominated indoles were then compared to a range of synthetic indoles to determine structure-activity relationships...

Pancreatic adenocarcinoma (PDAC) is one of the leading cause of cancer death due to its highly aggressive biological nature and resistance to chemotherapies. Former study also indicated that miR-21 in cancer-associated fibroblasts (CAFs) is an important regulator of their activation. However, whether miR-21 in CAFs would regulate PDAC's tumor microenvironment and leading to drug resistance remain unknown. In this study, we evaluated the relationship among CAFs activation, miR-21 expression level and drug resistance using PDAC patient tumor samples...

Topical drug administration for back of the eye delivery is extremely challenging due to the presence of protection mechanisms and physiological barriers. Self-assembled polymeric nanomicelles have emerged as promising vehicles for drug delivery. Apart from serving as an inert nanocarrier for therapeutic agents, polymeric nanomicelles are known to bypass mononuclear phagocytic system (MPS) and efflux transporters thereby improving drug bioavailability. In this investigation, a highly efficacious biotinylated lipid prodrug of cyclic cidofovir (B-C12-cCDF) was formulated within polymeric nanomicelles as a carrier for targeted retinal delivery...

The C-C chemokine receptor type 3 (CCR3) is the receptor for eotaxins (CCL-11, 24, 26), RANTES (CCL-5) and MCP-3 (CCL-7). It was reported that an inhibition of CCR3 by antagonists or antibodies reduces the degree of laser-induced choroidal neovascularization in mice, a model for wet age-related macular degeneration (AMD). Although several chemokine receptors have the potential of reducing the degree of the chronic inflammation in experimental dry AMD, the association of CCR3 remains unknown. The purpose of this study was to determine the role played by CCR3 in the death of 661W cells which are cells of a murine photoreceptor-derived cell line as an in vitro model of dry AMD...

BACKGROUND: The involvement of inflammatory components in the pathophysiology of low back pain is poorly understood. It has been suggested that spinal manipulative therapy (SMT) may exert anti-inflammatory effects. PURPOSE: To determine the involvement of inflammation-associated chemokines (CC series) in the pathogenesis of non-specific low back pain and to evaluate the effect of SMT on that process. METHODS: Patients presenting with non-radicular, non-specific low back pain (minimum pain score 3 on 10 point visual analogue scale, VAS) were recruited according to stringent inclusion criteria...

BACKGROUND: Immunological non response represents the Achilles heel in the combination antiretroviral treatment (cART) effectiveness, and increases risk of clinical events and death. CD8 T cells play a crucial role in controlling HIV replication and polyfunctional HIV-specific CD8 T cells have been associated with non-progressive HIV infection. However, the possible role of polyfunctional CD8 T cells in predicting post-treatment immune reconstitution has not yet been explored. The aim of this study was to identify functional markers predictive of immunological response to cART in chronic HIV-infected patients...

Cancer cell lines (CCL) are important tools for cancer researchers world-wide. However, handling of cancer cell lines is error-prone, and critical errors such as misidentification and cross-contamination occur more often than acceptable. Based on the fact that CCL today very often are sequenced (partly or entirely) anyway as part of the studies performed, we developed Uniquorn, a computational method that reliably identifies CCL samples based on variant profiles derived from whole exome or whole genome sequencing...

CCR-2 signaling regulates recruitment of monocytes from the bone marrow into the bloodstream and then to sites of infection. We sought to determine whether CCL-2/CCR-2 signaling is involved in the killing of Staphylococcus aureus by murine bone marrow cells (BMCs). The intermittent link of reactive oxygen species (ROS)-NF-κB/p38-MAPK-mediated CCL-2 production in CCR-2 signaling prompted us to determine whether neutralization of CCR-2 augments the response of murine fresh BMCs (FBMCs) after S. aureus infection...
