Berberine (BBR) is a well-known anti-diabetic herbal medicine in Asia due to its beneficial effects on insulin sensitivity, glucose metabolism and glycolysis. Here, we identified the critical role of phosphatidylinositol 3-kinase (PI3K)/Akt involved BBR cellular defense mechanisms and first revealed the novel effect of BBR on nuclear factor(More)
Reactive oxygen intermediates production and apoptotic damage induced by high glucose are major causes of neuronal damage in diabetic neuropathy. Berberine (BBR), a natural antidiabetes drug with PI3K-activating activity, holds promise for diabetes because of its dual antioxidant and anti-apoptotic activities. We have previously reported that BBR attenuated(More)
BACKGROUND AND PURPOSE Spinal muscular atrophy (SMA) is a progressive neuromuscular disease. Since disease severity is related to the amount of survival motor neuron (SMN) protein, up-regulated functional SMN protein levels from the SMN2 gene are considered a major SMA drug-discovery strategy. In this study, we investigated the possible effects of(More)
BACKGROUND AND AIMS A recent neuroimaging study discovered the neurotoxicity effects of homocysteine (Hcy), which is only seen in elderly women. Estrogens exert a variety of actions on brain function that influence cognitive function, mood, and neuroprotection. The Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2(More)
OBJECTIVE To establish and evaluate the effectiveness of a comprehensive next-generation sequencing (NGS) approach to simultaneously analyze all genes known to be responsible for the most clinically and genetically heterogeneous neuromuscular diseases (NMDs) involving spinal motoneurons, neuromuscular junctions, nerves, and muscles. METHODS All coding(More)
Polyalthia longifolia var. pendula is used as an antipyretic agent in indigenous systems of medicine. Microglia-mediated inflammation plays an important role in the pathway leading to neuronal cell death in a number of neurodegenerative diseases. The aim of this study was to investigate the effects of 6-hydroxycleroda-3,13-dien-15,16-olide (PL3) extracted(More)
Aging populations with neurodegenerative disorders will gradually become a greater problem for society. Serum deprivation-induced cell death is recognized as one of the standard models for the study of neurotoxicity. Increasing evidence indicates that cGMP/PKG pathway may play a rescue role in serum deprivation-induced toxicity. The aim of this study was to(More)
Propofol is a widely used intravenous anesthetic. The aim of this study was to investigate the roles of nuclear factor erythroid-2-related factor 2 (Nrf2) and NADPH oxidase (NOX) in propofol protection in inflammatory conditions induced by lipopolysaccharide (LPS). Human alveolar epithelial cells (A549 cell line) were incubated with propofol (10, 25, and 50(More)
Spinal muscular atrophy (SMA) is an autosomal recessive motor neuron disease caused by deficiency of the survival of motor neuron (SMN) protein, which leads to synaptic defects and spinal motor neuron death. Neuromuscular junction (NMJ) abnormalities have been found to be involved in SMA pathogenesis in the SMNΔ7 SMA mouse model. However, whether similar(More)
Oxidative stress and survival motor neuron (Smn) protein deficiency are the major causes of motor neuronal death. Naloxone exhibits neuroprotection against ischemic stroke and anti-inflammation. In this study, we determined whether nanomolar naloxone provides neuroprotection under oxidative stress (H2O2) and Smn deficiency in a motor neuron-like cell line,(More)
