Members of the transforming growth factor-β (TGF-β) family are known to regulate the commitment of mesenchymal stem cells to an adipocyte lineage and the differentiation of preadipocytes to adipocytes. However, the roles of TGF-β family members in mature adipocytes are not known. The present study explored the modulation of cell function in 3T3-L1 adipocytes treated with the TGF-β family members TGF-β1, activin A, activin B, bone morphogenetic protein (BMP) 4, and BMP7. These TGF-β family members modulated the expression of some adipokines; activin A upregulated leptin expression, and activin B downregulated the expression of plasminogen activator inhibitor-1...

Serum periostin has been proposed as a surrogate biomarker of Th2 inflammatory response in patients with asthma, but its predictive role in hospitalized patients with COPD has not been evaluated. The aim of the present observational prospective cohort study was to evaluate the possible role of serum periostin as predictor of outcome in COPD patients hospitalized for AECOPD. Serum periostin was measured on admission and at discharge in patients admitted to the hospital for a COPD exacerbation. Patients were followed-up for 1year for future exacerbations, hospitalizations and mortality...

Genome wide association studies and fine mapping has established a firm link between the IL2RA gene, encoding the interleukin-2 receptor α-chain CD25, and susceptibility to multiple sclerosis (MS). We hypothesized that gene expression in peripheral blood mononuclear cells (PBMCs) from healthy controls (HCs) and MS patients are associated with IL2RA SNP rs2104286 and that gene expression levels correlate with soluble CD25 (sCD25) concentrations - that are affected by rs2104286. We used the Affymetrix Human Gene ST 1...

Resistant starch generated after treating ordinary starch is of great significance to human health in the countries with overnutrition. However, its functional evaluation in the human body has been rarely reported. By determining the lactate metabolic flux, 12 serum enzymes expression level and 38 serum cytokines in healthy volunteers, the variation in cytokine network and lactate metabolic network in serum were investigated to compare the mechanism of the physiological effects between the two starches. The results indicated that compared with digestible starch, resistant starch had anti-inflammatory effects, increased anabolism, and decreased catabolism...

BACKGROUND: Rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLSs) play a crucial role in RA through producing inflammatory cytokines and proteases which could cause cartilage destruction. We showed previously that elevated expression of tumor necrosis factor receptor-associated factor 6 (TRAF6) in RA synovium correlated significantly with the severity of synovitis and the number of infiltrated inflammatory cells. The aims of this study are to detect the roles of TRAF6 in RA-FLSs...

Cancer cachexia is characterised by involuntary weight loss associated with systemic inflammation and metabolic changes. Studies aimed at maintaining lean body mass in cachectic tumour-bearing hosts have made important contributions reducing the number of deaths and improving the quality of life. In recent years, leucine has demonstrated effective action in maintaining lean body mass by decreasing muscle protein degradation. Currently, there is a growing need to understand how leucine stimulates protein synthesis and acts protectively in a cachectic organism...

Cytokine-like protein 1 (CYTL1) is a small widely expressed secreted protein lacking significant primary sequence homology to any other known protein. CYTL1 expression appears to be highest in the hematopoietic system and in chondrocytes; however, maintenance of cartilage in mouse models of arthritis is its only reported function in vivo. Despite lacking sequence homology to chemokines, CYTL1 is predicted by computational methods to fold like a chemokine, and has been reported to function as a chemotactic agonist at the chemokine receptor CCR2 in mouse monocyte/macrophages...

Th2 cell differentiation involves complex changes in expression of multiple genes, many of which have poorly characterized roles. In a gene expression microarray analysis of human primary CD4(+) effector T subsets, we identified that an adaptor protein, GAB2, was preferentially expressed in human Th2 cells. The role of GAB2 in human Th2 cells is unknown. Through analysis of primary and in vitro differentiated human T effector subsets, we confirmed that human Th2 cells preferentially expressed GAB2. Further analysis of public gene expression microarray data of STAT6-knockdowned Th2 cells indicated that GAB2 expression was regulated by IL-4 and STAT6...

BACKGROUND: The dynamics of the extracellular matrix (ECM) fibrosis process in dilated cardiomyopathy (DCM) may be assessed non-invasively by means of serum markers of fibrosis. AIM: To explore the kinetics of serum markers of fibrosis during a 12-month follow-up in DCM. METHODS: We included 70 consecutive DCM patients (pts) (48±12.1years, EF 24.4±7.4%) with new-onset (n=35, duration <6months) and chronic DCM (n=35, >6months). Markers of collagen type I and III synthesis - procollagens type I and III carboxy- and amino-terminal peptides (PICP, PINP, PIIICP, PIIINP), and ECM metabolism controlling factors - tumor growth factor beta-1 (TGF1-β), and connective tissue growth factor (CTGF) - were measured in serum at baseline, and at 3- and 12-month follow-up...

A key component during sepsis is the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway, of which the PI3K-γ isoform is a major regulator in many inflammatory responses. However, the role of PI3K-γ in the development of sepsis-induced myocardial dysfunction (SIMD) is unknown. In this study, we established a model of SIMD induced by lipopolysaccharide (LPS), subsequently used the selective inhibitor LY294002 and AS605240 to block the effect of PI3K and PI3K-γ, respectively. Cardiac function was evaluated by echocardiography, hearts were obtained for histological and protein expression examinations...

Interleukin 2 (IL-2) is a pro-inflammatory cytokine that is mainly synthesized by immunoregulatory T helper cells and which plays an important role in antitumor immunity. Helicobacter pylori (H. pylori) is a gram-negative bacterium that colonizes the gastric mucosa and induces the production of IL-2. This process increases the magnitude of inflammation and may influence the development of gastric pathologies. In light of the possible involvement of IL-2 and the presence of H. pylori in gastric diseases, this study investigated possible associations between the IL-2 polymorphisms +114 T>G (rs2069763) and -330 T>G (rs2069762) and the development of gastric cancer; these associations were then correlated with the presence of H...

In adipose tissue, D-dopachrome tautomerase (DDT), a cytokine with structural similarity to macrophage migration inhibitory factor, is mainly expressed in adipocytes rather than preadipocytes and acts as an anti-obesity adipokine in an autocrine manner. However, its transcriptional regulation is largely unknown. In order to explore molecules affecting DDT transcription, a chemical library screening using HEK293 cells stably expressing a DDT promoter-reporter construct was performed. Several derivatives of 5-aminoimidazole-4-carboxamide-1-β-d-ribofuranoside (AICAR), an AMP-activated protein kinase (AMPK) activator, were identified as transcriptional activators of the DDT gene...
