The N-myc downstream-regulated gene 1 (ndrg1) is highly expressed in N-myc knock-out mice through an unknown regulatory mechanism. As one member of the human NDRG gene family, NDRG2 encodes a protein highly homologous to Ndrg1. However, it is uncertain whether the expression of human NDRG2 is regulated by Myc because mouse ndrg2 and -3 are not affected by(More)
The most severe form of brain glioma, glioblastoma (GBM), is highly malignant and usually resistant to chemotherapy. Therefore, discovery of new targets for gene therapy is important. Using subtraction cloning, we identified the human N-Myc downstream-regulated gene 2 (hNDRG2), located at chromosome 14q11.2, as a gene that is significantly suppressed in GBM(More)
The NDRG2 gene belongs to a family of N-Myc downstream-regulated genes (NDRGs) and is expressed in many normal tissues. NDRG2 gene expression has been shown to be regulated in the stress response of certain cells. However, its function is not yet fully understood. Many studies have demonstrated that hypoxia, one of the stress responses, induced apoptosis in(More)
The tumor suppressor, p53, is a transcription factor which can modulate the transcription of a number of target genes that are involved in cell-cycle arrest and apoptosis. However, the apoptotic pathway mediated by p53 is not fully understood. Here, we showed that N-Myc downstream-regulated gene 2 (NDRG2) is a new target gene that is regulated by p53. NDRG2(More)
In order to know whether any protein tyrosine kinase (PTK) is involved in the over-proliferation and erosiveness of synovial fibroblasts (SF) of rheumatoid arthritis (RA) patients, RT-PCR and RNA dot blotting were done to analyse PTKs profile in RA SF. Platelet-derived growth factor receptor A (PDGFRA), insulin-like growth factor 1 receptor (IGF-1R), Janus(More)
G protein-coupled receptor kinase-2 (GRK),also known as beta1-adrenergic receptor kinase(beta-ARK1), plays an important role in agonist-induced desensitization of the beta-adrenergic receptors. Activation of protein kinase C (PKC) is able to stimulate phosphorylation and activation of GRKs and induce desensitization of G protein-coupled receptor. However,(More)
Circular RNAs (circRNAs) are a naturally occurring type of universal and diverse endogenous noncoding RNAs which unlike linear RNAs, have covalently linked ends. They are usually stable, abundant, conserved RNA molecules and often exhibit tissue/developmental-stage specific expression. Functional circRNAs have been identified to act as microRNA sponges and(More)
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease in the world. Hydrogen sulfide (H2S) plays an important role in physiology and pathophysiology of liver. However, whether exogenous H2S could mitigate the hepatic steatosis in mice remains unclear. The aim of this study is to evaluate the effects of H2S on fatty liver. (More)
Although Sirt2 is primarily expressed in oligodendrocytes of the central nervous system, its role in oligodendroglial lineage differentiation is not fully understood. Our findings demonstrate that the transcription factor Nkx2.2 binds to the Sirt2 promoter via histone deacetylase 1 (HDAC-1), the binding site for Nkx2.2 maps close to the start codon of the(More)
Neuropilin-1 (NRP-1) is a transmembrane glycoprotein. As a VEGF co-receptor, NRP1 significantly enhances VEGFR2 signaling and promotes vascular permeability and migration. The purpose of this study was to evaluate the effects of an NRP-1 inhibitor, ATWLPPR peptide, on the early stages of diabetic retinopathy. Eight-week-old male C57BL/6 mice were divided(More)
