Osteoarthritis (OA) is the most common form of arthritis involving major structural changes of peripheral joints and local or systemic inflammation and in lack of therapeutic approaches because of complexity of underlying molecular basis. Our previous work showed that HS6ST2, an enzyme involved in the transfer of sulfate, is downregulated in cartilage tissues of OA patients compared with normal donors, but little is known about its regulatory mechanism. In this study, we demonstrated that the expression of HS6ST2 was lower in OA-damaged cartilage than smooth cartilage from the same patient...

It has been shown that propofol can induce widespread apoptosis in neonatal mouse brains followed by long-term cognitive dysfunction. However, selective brain area and cell vulnerability to propofol remains unknown. This study was aimed to dissect toxic effect of propofol on multiple brain cells, including neurons, astrocytes, oligodendrocytes, and neural stem cells (NSCs). Seven-day-old mice were intraperitoneally administrated propofol or intralipid as a vehicle control for 6 hours. To identify vulnerable cells undergoing apoptosis following propofol exposure, brain sagittal sections were co-stained with antibodies against an apoptosis marker along with neuron, astrocyte, oligodendrocyte, or NSC markers using immunofluorescence staining...

Autophagy is involved in both innate and adaptive immune regulation. We propose that autophagy regulates activation of TLR3 in macrophages and is thereby essential for development of pristane-induced arthritis. We found that pristane treatment induced autophagy in macrophages in vitro and in vivo, in spleen cells from pristane injected rats. The induced autophagy was associated with STAT1 phosphorylation and expression of IRF1 and TLR3. Blocking the pristane activated autophagy by Wortmannin and Bafilomycin A1 or by RNAi of Becn1 led to a downregulation of the associated STAT1-IRF1-TLR3 pathway...

Oxymatrine (OMT) is a type of alkaloid extracted from a traditional Chinese medicinal herb, Sophora flavescens. Although the antitumor activities of OMT have been observed in various cancers, there are no reports regarding the effects of OMT on human synovial sarcoma. In the present study, we analyzed the antitumor activities of OMT in SW982 human synovial sarcoma cells and determine whether high mobility group box protein 1 (HMGB1)-mediated autophagy was associated with its therapeutic effects. We found that OMT exhibited antitumor activity in SW982 cells and facilitated increases in autophagy...

The pLKO.1-TRC plasmid has been a popular and widely used vector due to its simple handling and stability. The huge RNAi database, a TRC library, has been established based on this vector. However, this plasmid only has a puromycin-resisted gene for selecting, which limits its application in microscopy and fluorescence-activated cell sorting (FACS). In the present work, PCR, restriction endonuclease digestion and molecular cloning techniques were used to insert the gene decoding green fluorescent protein (GFP) without changing the structure of original plasmid to extend its application...

MicroRNAs (miRNAs) are a class of endogenous and non-coding single-stranded RNAs of approximately 22 nucleotides, many of which are evolutionarily conserved. Genome-wide association studies have identified a robust statistical association between the MIR137 gene and schizophrenia in Europeans, which was replicated in the Han Chinese population in a case-control study. In the previous study, we provided evidence for a significant association between the EFNB2 gene and schizophrenia in Han Chinese subjects. In the current study, we utilized computational analysis, vector construction of point mutations, luciferase reporter assays and gene expression assays including RT-qPCR and western blotting methods to investigate miR-137 directly targeting EFNB2 gene and explore the reversal effect of a genetic variant of SNP rs550067317 in the putative seed-pair region of EFNB2 3'-UTR...

Thioredoxin reductase 2 (TrxR2) is a selenium (Se) containing protein. Se deficiency is associated with an endemic osteoarthropathy characterized by impaired cartilage formation. It is unclear whether TrxR2 have roles in cartilage function. We examined the effects of TrxR2 on chondrogenic ATDC5 cells through shRNA-mediated gene silencing of TrxR2. We demonstrated TrxR2 deficiencies could enhance chondrogenic differentiation and apoptosis of ATDC5 cells. TrxR2 deficiencies increased accumulation of cartilage glycosaminoglycans (GAGs) and mineralization...

Osteoarthritis (OA) is characterized by degeneration of articular cartilage, limited intraarticular inflammation with synovitis, and changes in peri-articular and subchondral bone. In recent years, more and more evidence demonstrated that microRNAs (miRNAs) play important roles in the molecular mechanisms in OA by suppressing gene expression at the post-transcriptional level. In current study, histological staining of toluidine blue and cartilage-specific gene express revealed that the bone matrix gelatin (BMG) rat model could demonstrate the different development of cartilage...

Based on pristane-induced arthritis (PIA), we found that T cells mediate TLR3 overexpression in fibroblast-like synoviocytes (FLS). The aim of this study is to determine key factors by which T cells induce TLR3 expression. Rat FLS were co-cultured with pristane primed T cell conditioned medium (PPT medium), and TLR3 expression of FLS was significantly induced. TNF-α, IFN-γ and IL-17 were dominantly expressed in PIA T cells. The overexpression of TLR3 and its related genes in FLS co-cultured with PPT medium could be reduced through blocking TNF-α pathway...

Pdcd4 has been known as a tumor-suppressor gene initially and is up-regulated during apoptosis. Surprisingly, we found that Pdcd4 was differentially expressed in the lung from E3 rats with AIPI, an animal model for asthma, but the precise role of Pdcd4 in AIPI still remained to be defined. In the present study, we first evaluated the expression of Pdcd4 in lung from control and AIPI rats with RT-qPCR, Western blot, and immunohistochemistry. Then, we investigated the effects of intervention of Pdcd4 on markers of macrophage alternative activation and airway remodeling...
