OBJECTIVE To investigate the effect and mechanism of mocetinostat on diminishing epidural fibrosis. Dysregulated wound repair usually occurs after injury or surgery and is featured by excessive scar tissue contributed by fibrosis. Increasing researches demonstrated that histone acetylation, an epigenetic alteration, plays a crucial role in fibrosis. However, the mechanism of the complicated process remains unclear. In the current study, the effect of histone deacetylase (HDAC) inhibitor mocetinostat in a rat model of epidural fibrosis was detected, and it was discovered that mocetinostat suppressed myofibroblast activation and increased apoptosis by reducing Akt/GSK3b signaling. read more PATIENTS AND METHODS First, the levels of histone acetylation in the patients' epidural fibroblasts were analyzed. Then, mRNAs and proteins obtained from human fibroblasts following TGF-β activation and mocetinostat treatment in vitro were used to examine the influence of mocetinostat on the activation and survival of fibroblasts, so as to explore the related mechanism of mocetinostat. The laminectomy model was established in rats to observe the therapeutic effect of mocetinostat on epidural scar tissues. RESULTS In this research, it was found that the increase of HDAC1 in human dura scar was accompanied by the aggravation of fibrosis. In addition, cell assay demonstrated that mocetinostat inhibited fibroblast activation and accelerated apoptosis by inhibiting Akt/GSK3b pathway. In the rat model, mocetinostat weakened scar hyperplasia and collagen deposition and effectively inhibited the process of epidural fibrosis. CONCLUSIONS The above results indicate that mocetinostat inhibits HDAC1 expression and decreases the conduction of the AKT/GSK3b pathway in fibroblasts, leading to myofibroblast activation and apoptosis elevation. Hence, mocetinostat ameliorates epidural fibrosis.OBJECTIVE The purpose of this study was to investigate the effect of Casitas b-lineage lymphoma b (Cblb) on the regulation of T follicular helper (Tfh) in the development of lupus nephritis. MATERIALS AND METHODS The Tfh (CD4+CXCR5+PD-1+) cells in peripheral blood were analyzed by flow cytometry. Forty mice were divided into 4 groups (10/group), WT, lpr, Cblb-/- and lpr.Cblb-/-. Urine protein, serum creatinine, blood urea nitrogen (BUN), dsDNA, and antinuclear antibody (ANA) titer of mice were monitored once every four weeks. Peripheral blood mononuclear cells (PBMCs) from mice were collected to assess circulating Tfh. The expressions of Cblb in Tfh cells were regulated by transfecting siRNA and overexpression plasmid approach in vitro. RESULTS The patients with lupus nephritis (LN) had abnormal renal clinical manifestations compared with healthy volunteers. The peripheral Tfh cells were increased and the expression of Cblb were downregulated in patients with LN (p less then 0.05). Both lpr mice and lpr.Cblb-/- mice had LN symptoms. LN symptoms were more serious in lpr.Cblb-/- mice compared with that in lpr mice (p less then 0.05). The number of Tfh cells in peripheral blood from lpr.Cblb-/- mice was significantly higher than that from lpr mice (p less then 0.05). Overexpression of Cblb in Tfh cells led to reduction of IgG expression, while the knockdown of Cblb in Tfh cells was accompanied by increased expression of immunoglobulin (IgG) (p less then 0.05). CONCLUSIONS Cblb showed a negative regulatory effect on Tfh. The deletion of Cblb may be a key factor in progression of renal injury.OBJECTIVE To investigate the protective effect of miR-129-5p on ischemia-reperfusion (I/R) injury via targeting high mobility group box-1 (HMGB1). MATERIALS AND METHODS Rat models of myocardial I/R and hypoxia/reoxygenation (H/R) cardiomyocytes were established, and the miR-129-5p and HMGB1 expression levels in myocardium of I/R rats and in cardiomyocytes of H/R rats were quantified by RT-PCR. The over-expression of miR-129-5p was performed on I/R rats, and the over-expression of miR-129-5p and down-regulation of HMGB1 were performed on cardiomyocytes of H/R rats. Triphenyltetrazolium chloride (TTC) staining was used to measure myocardial infarct size (IS). TUNEL (TdT-mediated dUTP end nick labeling) staining was employed to observe cardiomyocyte apoptosis in the myocardium of rats, and flow cytometry to observe cardiomyocyte apoptosis of I/R and H/R rats respectively. Dual-Luciferase reporter assay was used to verify the target relation between miR-129-5p and HMGB1. RESULTS MiR-129-5p was lowly expressed and HMGB1 was highly expressed in myocardial I/R injury rats and cardiomyocytes of H/R rats. Over-expression of miR-129-5p effectively reduced myocardial IS and cardiomyocyte apoptosis in rats with myocardial I/R injury, and significantly down-regulated the pro-apoptotic protein Bax, as well as significantly up-regulated the anti-apoptotic protein Bcl-2. Either over-expression of miR-129-5p or low-expression of HMGB1 in cardiomyocytes of H/R rats also achieved the same effects as described above. Dual-Luciferase reporter assay determined that miR-129-5p was a target for HMGB1. CONCLUSIONS MiR-129-5p plays a protective role on myocardial I/R injury by regulating HMGB1 expression. Besides, it inhibits cardiomyocyte apoptosis and is expected to become a novel molecular marker or therapeutic target for myocardial I/R injury.OBJECTIVE Myocardial ischemia-reperfusion injury (MIRI) is a common problem in heart-related diseases. The aim of this study was to explore the protective effects of STRAP on cardiomyocytes in the MIRI process and its mechanisms. MATERIALS AND METHODS We used SD rats to construct a MIRI model and increased the expression of STRAP in myocardial tissue by Entranster to detect the effect of STRAP on rat myocardial tissue. In addition, we cultured rat cardiomyocyte cell line H9c2 cells and constructed a hypoxia-reoxygenation model to detect the protective effect of STRAP on H9c2 cells. LY294002, an inhibitor of the PI3K/PDK1/Akt signaling pathway, was used to validate the mechanism by which STRAP protects cardiomyocytes. RESULTS Overexpression of STRAP significantly reduced the activity of MDA in myocardial tissue and increased the activity of SOD. read more STRAP also substantially lowered CK and LDH levels in rat serum and increased Na+-K+-ATPase and Ca2+-Mg2+-ATPase activity. In addition, overexpression of STRAP considerably reduced endoplasmic reticulum stress (ERS) and apoptosis levels in H9c2 cells.
