Voltage-gated sodium channels play a crucial role in the initiation and propagation of neuronal action potentials. Genistein, an isoflavone phytoestrogen, has long been used as a broad-spectrum inhibitor of protein tyrosine kinases (PTK). In addition, genistein-induced modulation of ion channels has been described previously in the literature. In this(More)
The Arabidopsis proline-rich extensin-like receptor kinase (PERK) family consists of 15 predicted receptor kinases. A comprehensive expression analysis was undertaken to identify overlapping and unique expression patterns within this family relative to their phylogeny. Three different approaches were used to study AtPERK gene family expression, and included(More)
Cdc42, a member of the Rho-family small GTP-binding proteins, is a pivotal signaling switch that cycles between active GTP-bound and inactive GDP-bound forms, controlling actin cytoskeleton organization and cell polarity. In this report, we show that MgCdc42, a Cdc42 ortholog in Magnaporthe grisea, is required for its plant penetration. Consequently, the(More)
DNA methylation acts in concert with restriction enzymes to protect the integrity of prokaryotic genomes. Studies in a limited number of organisms suggest that methylation also contributes to prokaryotic genome regulation, but the prevalence and properties of such non-restriction-associated methylation systems remain poorly understood. Here, we used single(More)
Inwardly rectifying potassium channels play an important role in the maintenance of membrane potential in neurons and myocardium. Identification of functional regulation mechanisms concerning these channels may lead to the development of specific modulators for these channels. Genistein is an isoflavone with potent inhibitory activity on protein tyrosine(More)
Gaucher disease (GD) is caused by insufficient activity of acid β-glucosidase (GCase) resulting from mutations in GBA1. To understand the pathogenesis of the neuronopathic GD, induced pluripotent stem cells (iPSCs) were generated from fibroblasts isolated from three GD type 2 (GD2) and 2 unaffected (normal and GD carrier) individuals. The iPSCs were(More)
Resting-state functional Magnetic Resonance Imaging (rsfMRI) is a powerful tool to investigate neurological and psychiatric diseases. Recently, the evidences linking the scaling properties of resting-state activity and the personality have been accumulated. However, it remains unknown whether the personality is associated with the scale-free dynamics of(More)
Our previous studies have shown that decreased expression of Annexin A7 elevates apoptosis in Hca-P cells, a hepatocarcinoma cell line with lymphatic metastatic potential. In this study, RNA interference technique was used to down-regulate the expression of Annexin A7, and unmanipulated Hca-P cells and transfected nonspecific-sequence Hca-P cells as(More)
KCNQ2/3 currents are the molecular basis of the neuronal M currents that play a critical role in neuron excitability. Many neurotransmitters modulate M/KCNQ currents through their G-protein-coupled receptors. Membrane PtdIns(4,5)P2 hydrolysis and channel phosphorylation are two mechanisms that have been proposed for modulation of KCNQ2/3 currents. In this(More)
Centrosome stability is required for successful mitosis in mammalian cells. Amplification of the centrosome leads to chromosomal missegregation and generation of aneuploidy, which are closely associated with cell transformation and tumorigenesis (Doxsey, S. J. (2001) Nat. Cell Biol. 3, E105-E108; Hinchcliffe, E. H., and Sluder, G. (2001) Genes Dev. 15,(More)
