IL-37 has been described as a natural inhibitor of immune responses. Monoclonal antibody (mAb) against human IL-37b with high affinity and specificity can serve as a molecular probe to detect IL-37 and study IL-37 functions, mechanisms and related signal pathways in inflammatory diseases. However, there are very few such mAbs against human IL-37 commercially available so far. In the current study, monoclonal antibodies against human IL-37b were developed by fusing splenocytes from immunized mouse with SP2/0 myeloma cells and polyethylene glycol...

The BRAF activating mutation, harbored by approximately 10% of colorectal cancers (CRC), confers dramatic prognosis to advanced diseases. In early-stage setting, the identification of the BRAF mutation does not impact the therapeutic decision. Yet, the BRAF mutation could be considered as a stratification factor in adjuvant trials, because of its prognostic impact after relapse. Moreover, both BRAF mutation and mismatch repair (MMR) statuses should be determined in all CRC to help identify sporadic tumors versus Lynch syndrome-related tumors...

Surgeries to correct congenital heart diseases are increasing in Brazil and worldwide. However, even with the advances in surgical techniques and perfusion, some cases, especially the more complex ones, can develop heart failure and death. A retrospective study of patients who underwent surgery for correction of congenital heart diseases with cardiopulmonary bypass (CPB) in a university tertiary-care hospital that died, showed infarction in different stages of evolution and scattered microcalcifications in the myocardium, even without coronary obstruction...

Little information has so far been known on the effects of synthetic progestogen dydrogesterone (DDG) in organisms like fish. This study aimed to investigate the effects of DDG on the transcriptional and biochemical alterations in zebrafish eleuthero-embryos. Zebrafish eleuthero-embryos were analyzed for the transcriptional alterations by real-time quantitative PCR (RT-qPCR) and biochemical changes by attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FITR) after 144 h exposure to DDG...

BACKGROUND: Extra-oral bitter taste receptors have been associated with innate bacterial defence mechanisms. Genetic variation in T2R38 functionality has been shown to be associated with susceptibility to upper respiratory tract infections and chronic rhinosinusitis (CRS). We sought to independently assess the influence of bitter taste receptor genotype on the presence of culturable bacteria in the sinuses. METHODOLOGY: A cross-sectional analysis of patients with CRS undergoing surgery was performed...

BACKGROUND/AIMS: Osteogenic differentiation of mesenchymal stem cells (MSCs) plays a crucial role in bone regeneration and bone reparation. This complex process is regulated precisely and firmly by specific factors. Recent studies have demonstrated that miR-125b regulates osteogenic differentiation, but little is known about the molecular mechanisms of this regulation. Furthermore, how miR-125b regulates the osteogenic differentiation of MSCs still needs elucidation. METHODS: In the present study, human bone marrow-derived mesenchymal stem cells (hBMSCs) were isolated and induced to osteoblasts with miR-125b inhibition or overexpression...

BACKGROUND: Recent evidence has indicated that long non-coding RNA (lncRNA) is involved in the pathogenesis of type 2 diabetes, but nothing is known about lncRNA expression changes of lymphatic endothelial cells in response to type 2 diabetes. METHODS: The GSE38396 dataset was downloaded from the Gene Expression Omnibus database and the probe sets of Human Gnome U133 Plus2.0 microarray were annotated for lncRNA. Differentially expressed lncRNAs between diabetic and non-diabetic lymphatic endothelial cells were calculated...

BACKGROUND: BMP9 induces both osteogenic and adipogenic differentiation of mesenchymal stem cells (MSCs). Nell1 is a secretory glycoprotein with osteoinductive and anti-adipogenic activities. We investigated the role of Nell1 in BMP9-induced osteogenesis and adipogenesis in MSCs. METHODS: Previously characterized MSCs iMEFs were used. Overexpression of BMP9 and NELL1 or silencing of mouse Nell1 was mediated by adenoviral vectors. Early and late osteogenic and adipogenic markers were assessed by staining techniques and qPCR analysis...

BACKGROUND/AIMS: Autophagy is a lysosomal degradation pathway that is essential for cellular survival, differentiation, and homeostasis. Sirtuin 1 (SIRT1), a NAD+-dependent deacetylase, plays a pivotal role in modulation of autophagy. Recent studies found that autophagy was involved in the regulation of inflammatory response. In this study, we aimed to determine the effect of SIRT1 on autophagy and inflammation, and whether autophagy can regulate the inflammatory response in vascular adventitial fibroblasts (VAFs)...

BACKGROUND AND AIMS: Parenterally-administered lipid emulsion (LE) is a key cause of enterocyte apoptosis under total parenteral nutrition, yet the pathogenesis has not been fully understood. CUGBP, Elav-like family member 1 (CELF1) has been recently identified as a crucial modulator of apoptosis, and thus this study sought to investigate its role in the LE-induced apoptosis in vitro. METHODS: Caco-2 cells were used as an in vitro model. The cells were treated with varying LEs derived from soybean oil, olive oil or fish oil, and changes in the apoptosis and CELF1 expression were assessed...

BACKGROUND: Emodin has anti-neoplastic activities on multiple tumors. However, the molecular mechanisms underlying this effect still remain to be fully understood. METHODS: Cell viability and cell cycle distribution were measured using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assays and flow cytometry, respectively. Cell invasion and migration were examined by transwell invasion and wound healing assays. Western blot analysis was performed to examine the phosphorylation and protein expression of AMP-activated protein kinase alpha (AMPKα), extracellular signaling-regulated kinase 1/2 (ERK1/2), peroxisome proliferators-activated receptor gamma (PPARγ), insulin-like growth factor (IGF) binding protein 1 (IGFBP1) and the transcription factor Sp1...
