The hippocampal dentate gyrus in the adult mammalian brain contains neural stem/progenitor cells (NS/PCs) capable of generating new neurons, i.e., neurogenesis. Most drugs of abuse examined to date decrease adult hippocampal neurogenesis, but the effects of cannabis (marijuana or cannabinoids) on hippocampal neurogenesis remain unknown. This study aimed at(More)
NDRG2, a member of the N-myc downstream-regulated gene (NDRG) family, is involved in cell differentiation and development. However, the distribution and function of Ndrg2 in the central nervous system remains unclear. Here, we analyzed the expression and distribution of Ndrg2 in the mouse brain and explored the potential physiological functions of Ndrg2.(More)
The widespread distribution of the tumor suppressor PTEN (phosphatase and tensin homolog deleted on chromosome 10) in the adult brain suggests its role in a broad range of brain functions. Here we show evidence supporting a physical interaction of PTEN with a region in the third intracellular loop (3L4F) of the serotonin 5-HT2C receptor (5-HT2cR, formerly(More)
The mechanisms underlying brain seizure tolerance, a phenomenon in which brief periods of seizures protect brain against the lethal effects of subsequent sustained seizures, are poorly understood. Because brain seizure tolerance and brain ischemia tolerance likely share certain common mechanisms, the recent evidence that activation of extracellular(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)
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)
At present, the details of lamina alterations after baculovirus infection remain elusive. In this study, a lamin gene in the Sf9 cell line of Spodoptera frugiperda was cloned. The open reading frame (orf) of the Sf9 lamin was 1860 bp and encoded a protein with a molecular weight of 70 kDa. A transfection assay with a red fluorescence protein (rfp)-lamin(More)
Polymerase chain reaction (PCR) technique is widely used in many experimental conditions, and Taq DNA polymerase is critical in PCR process. In this article, the Taq DNA polymerase expression plasmid is reconstructed and the protein product is obtained by rapid purification, ("Rapid purification of high-activity Taq DNA polymerase" (Pluthero, 1993 [1]),(More)
As a vital tumor suppressor, PTEN (Phosphatase and tension homolog deleted on chromosome 10) is involved in inherited syndromes, and is among the most frequently inactivated tumor suppressor gene in sporadic cancers. PTEN loss-of-function widely occurs in human cancers via a variety of mechanisms, including genetic alterations and posttranslational(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)
