CD14+ monocytes contain precursors for macrophages and fibrocytes, known to be involved in regulating airway remodeling in human asthma and distinguishable by the PM-2K marker. We sought to identify circulating subsets of PM-2K+ macrophage-like cells and evaluate their relationships to lung function, severity and control status. Circulating PM-2K+ macrophage-like cells and fibrocytes could be identified and distinguished between normal individuals (N = 152) and asthmatic subjects (N = 133) using multi-parametric flow cytometry...

Natural killer cells harnessed from healthy individuals can be expanded ex vivo using various platforms to produce large doses for adoptive transfer into cancer patients. During such expansion, NK cells are increasingly activated and more efficient at killing cancer cells. Adoptive transfer however introduces these activated cells into a highly immunosuppressive tumor microenvironment mediated in part by excessive transforming growth factor beta (TGF-beta) from both cancer cells and their surrounding stroma...

Chemotherapy is one of the main approach for ovarian cancer. Cancer stem cells (CSCs) escape chemotherapy and lead to chemoresistance. We previously demonstrated that cordycepin (Cd) inhibited metastasis in human ovarian carcinoma cells, the aim of this study is to investigate the effects of Cd on ovarian cancer stemness. TGF-beta was used to induce chemoresistance of chemotherapeutic agent cisplatin in SKOV-3 ovarian cancer cells. After treating with 100 μM of Cd, cell viability, the percentage of cancer stem cells, and the levels of matrix metalloproteinases (MMPs) were decreased in TGF-beta-induced SKOV-3 cells...

Renal interstitial fibrosis is the most common process by which chronic kidney diseases progress to end-stage renal failure. Epithelial-to-mesenchymal transitions (EMTs) play a crucial role in the progression of renal interstitial fibrosis. A newly identified cytokine, interleukin-like EMT inducer (ILEI), has been linked to EMT in some diseases. However, the effects of ILEI on renal tubular EMT have not yet been well established. Here, we characterize the expression of ILEI in tubular EMT and describe the role and mechanism of ILEI in transforming growth factor beta 1 (TGF-β1)-induced renal tubular EMT...

AIM: Thermal ablation therapy has recently emerged as a promising noninvasive treatment modality for localized solid malignancies. Except its direct tumor-cell-killing effect on local tumor tissues, the immunomodulatory effect has also long been noticed which too has substantial effect on clinical outcome, but it is complicated. Though much has been investigated and rich evidences have been achieved, the fundamental state and profile of immunomodulation by thermal ablation in cancer patients, its exact mechanism, especially the systematic mechanism, and its effect on antitumor immunity remain unclear...

BACKGROUND: The prevalence of both obesity and allergic diseases in children has increased over the last several decades. However, the direct relationship between diverse allergic diseases and obesity has varied in different studies. Therefore, we aimed to examine the effect of obesity on the incidence and severity of allergic rhinitis (AR) and the possible key inflammation mediators during AR. METHODS: A total of 3,126 healthy students (without chronic diseases) were recruited from 14 randomly selected secondary schools in Guangzhou, China...

To date, gene-environment (GxE) interaction studies in depression have been limited to hypothesis-based candidate genes, since genome-wide (GWAS)-based GxE interaction studies would require enormous datasets with genetics, environmental, and clinical variables. We used a novel, cross-species and cross-tissues "omics" approach to identify genes predicting depression in response to stress in GxE interactions. We integrated the transcriptome and miRNome profiles from the hippocampus of adult rats exposed to prenatal stress (PNS) with transcriptome data obtained from blood mRNA of adult humans exposed to early life trauma, using a stringent statistical analyses pathway...

Extracorporeal shock wave therapy (ESWT) considerably improves the appearance and symptoms of post-burn hypertrophic scars (HTS). However, the mechanism underlying the observed beneficial effects is not well understood. The objective of this study was to elucidate the mechanism underlying changes in cellular and molecular biology that is induced by ESWT of fibroblasts derived from scar tissue (HTSFs). We cultured primary dermal fibroblasts derived from human HTS and exposed these cells to 1000 impulses of 0...

The Fas/FasL signaling pathway is one of the major pathways that regulate apoptosis. Increasing studies have shown that the activation of the Fas/FasL signaling pathway is closely associated with testicular cell apoptosis. However, the mechanism involved is still unclear. We discuss recent findings regarding the molecular mechanisms by which environmental toxicants induce testicular pathology via Fas/FasL signaling. These findings suggest that Fas/FasL signaling is employed to impact the sensitivity (a response to external factors) of germ cells, disrupt steroidogenic hormone and cytokine metabolism mediated by Sertoli cells, and elicit the activation of NFAT (nuclear factor of activated T-cells) in Leydig cell apoptosis...

Tryptophan-aspartic acid (WD) repeat-containing protein 34 (WDR34), one of the WDR protein superfamilies with five WD40 domains, inhibits a transforming growth factor-beta (TGF-β) activated kinase 1 (TAK1)-associated NF-κB activation pathway. Nevertheless, little is known about the roles of WDR34 in cancer. The current study sought to elucidate the clinical relevance of WDRsfb34 in oral squamous cell carcinoma (OSCC). We found WDR34 down-regulation in OSCCs compared with normal control tissues using real-time quantitative reverse transcription-polymerase chain reaction, immunoblotting, and immunohistochemistry...

A cohort of 19 patients affected by chronic venous ulcers was recruited from our centre. A 4-mm punch biopsy from wound bed was taken before application of ALA 20% gel and repeated one hour after the first PDT irradiation. We observed a significant and progressive reduction of wounds mean volumes right after three ALA-PDT sessions (once per week; 4479.9 +/- 345.5 mm3 vs 34599 +/- 190.3 mm3, p < 0.01). On immunofluorescence staining from biopsy specimens, we observed a change in all tested stains of post treatment specimens compared to pre-treatment ones...

Hepatitis B virus (HBV) infection is a leading cause of liver damage and hepatic inflammation. Upon infection, effective antiviral responses by CD8+ T cells, CD4+ T cells, Natural killer (NK) cells, and monocytes can lead to partial or complete eradication of the viral infection. To date, many studies have shown that the production of inhibitory cytokines such as Interleukin 10 (IL-10), Transforming growth factor beta (TGF-β), along with dysfunction of the dendritic cells (DCs), and the absence of efficient innate immune responses could lead to T cell exhaustion, development of persistent infection, and inability to eradicate the viral infection from liver...

OBJECTIVES: Systemic sclerosis (SSc) is characterised by tissue fibrosis and vasculopathy with defective angiogenesis. Transforming growth factor beta (TGF-β) plays a major role in tissue fibrosis, including downregulation of caveolin-1 (Cav-1); however, its role in defective angiogenesis is less clear. Pigment epithelium-derived factor (PEDF), a major antiangiogenic factor, is abundantly secreted by SSc fibroblasts. Here, we investigated the effect of TGF-β and Cav-1 on PEDF expression and the role of PEDF in the ability of SSc fibroblasts to modulate angiogenesis...

Cardiac fibrosis is a common pathologic change along with pressure overload. Recent studies indicated that transient receptor potential (TRP) channels played multiple roles in heart. However, the functional role of transient receptor potential vanilloid-3 (TRPV3) in cardiac fibrosis remained unclear. The present study was designed to investigate the relationship between TRPV3 activation and pressure overload-induced cardiac fibrosis. Pressure overload rats were successfully established by abdominal aortic constriction (AAC), and cardiac fibrosis was simulated by 100 nM angiotensin II (Ang II) in neonatal cardiac fibroblasts...

Transforming growth factor beta (TGF-β) secretion from cells in the bone marrow (BM) niche affects hematopoietic stem cell (HSC) fate and has a cardinal role in HSC quiescence. BM mesenchymal stem cells (BM-MSCs), a component of the BM niche, may produce abnormal levels of TGF-β in Fanconi anemia (FA) and may play a role in bone marrow failure. Here, we molecularly and cellularly characterized FA BM-MSCs by addressing their immunophenotype, proliferation- and differentiation- capacity, reactive oxygen species (ROS) production, senescence activity as well as expression and secretion levels of TGF-β isoforms...

Avian primordial germ cells (PGCs) have valuable potentials to cell-based approaches for transgenic bird production. In this regard, improvement of avian PGC expansion in vitro is necessary. Among experimental avian species, quail is a good model for transgenic technology, especially due to its short generation time. In the present study, we have examined the proliferative effects of transforming growth factor β (TGF-β) on the quail PGCs. After isolation of quail PGCs from blood [Hamburger-Hamilton (HH stages 13-15)] and gonads (HH stages 28-30), these cells were cultured on quail embryonic fibroblasts (QEF)...

Carcinoma-associated fibroblasts (CAFs) influence tumor initiation, progression, and metastasis within the tumor-associated stroma. This suggests that CAFs would be a potential target for tumor therapy. Here we found that Hydrogen peroxide-inducible clone-5 (Hic-5), also named transforming growth factor beta-1-induced transcript 1 protein (Tgfb1i1), was strongly induced in CAFs found in human colorectal cancer. To investigate the role of Hic-5 in CAFs, we isolated CAFs and the control counterpart normal fibroblasts (NFs) from human colorectal cancer and non-cancerous regions, respectively...
