The protein kinase Akt is a crucial regulator of neuronal survival and apoptosis. Here we show that Akt activation is necessary for mobilization of large-conductance K(Ca) channels in ciliary ganglion (CG) neurons evoked by beta-neuregulin-1 (NRG1) and transforming growth factor-beta1 (TGFbeta1). Application of NRG1 to embryonic day 9 (E9) CG neurons increased Akt phosphorylation, as observed p...
PURPOSE The aim of this study was to evaluate changes in expressions of neuregulin (NRG)1 and erbB2 tyrosine kinase (ErbB2) in bladders of rats with cyclophosphamide (CYP)-induced interstitial cystitis (IC). METHODS Twenty-four Sprague-Dawley rats were divided into the IC group (n=16) and the control group (n=8). After inducing IC with intraperitoneal CYP injection, expressions of NRG1 and Er...
The link between cannabis and psychosis has been debated although there is substantial epidemiological evidence showing that cannabis increases the risk of psychosis. It has been hypothesized that schizophrenia patients carrying particular risk genes might be more sensitive to the psychosis-inducing effects of cannabis than other patients and healthy test subjects. Here we review the effects of...
Neuregulin-1 (NRG1) variations have been shown to modulate schizophrenia candidate endophenotypes related to brain structure and function. The aim of this study was to determine the effect of NRG1 on several oculomotor schizophrenia endophenotypes. The effects of 5 core single-nucleotide polymorphisms (SNPs) within the NRG1 gene to oculomotor parameters in a battery of oculomotor tasks (saccade...
NRG1 (neuregulin 1) belongs to the NRG family of EGF (epidermal growth factor)-like signalling molecules involved in cell-cell communication during development and disease. It plays important roles in the developing tissues of the nerves, heart and mammary glands. Particularly in neurobiology, NRG1 signalling is associated with synaptic transmission, myelination of Schwann cells and the human d...
Neuregulin 1 (NRG1) is associated with the pathogenesis of schizophrenia through controlling activation and signaling of neurotransmitter receptors. Influence to schizophrenia development by the NRG1 gene may differ in individuals, and genetic polymorphism is one of the factors affecting their differences. Association between three single nucleotide polymorphisms (SNPs) (rs7014762, -1174 A/T; r...
Uveal melanoma patients with metastatic disease usually die within one year, emphasizing an urgent need to develop new treatment strategies for this cancer. MEK inhibitors improve survival in cutaneous melanoma patients but show only modest efficacy in metastatic uveal melanoma patients. In this study, we screened for growth factors that elicited resistance in newly characterized metastatic uve...
Proteolytic shedding of cell surface proteins generates paracrine signals involved in numerous signaling pathways. Neuregulin 1 (NRG1) type III is involved in myelination of the peripheral nervous system, for which it requires proteolytic activation by proteases of the ADAM family and BACE1. These proteases are major therapeutic targets for the prevention of Alzheimer's disease because they are...
The cause of schizophrenia is unknown, but it has a significant genetic component. Pharmacologic studies, studies of gene expression in man, and studies of mouse mutants suggest involvement of glutamate and dopamine neurotransmitter systems. However, so far, strong association has not been found between schizophrenia and variants of the genes encoding components of these systems. Here, we repor...
Connexin 32 (Cx32), a gap junction protein, is found within the para-nodal region and Schmidt-Lanterman incisures of myelinating Schwann cells (SCs). In developing and regenerating peripheral nerves, pro-myelinating SCs express Cx32 mRNA and protein in conjunction with the expression of myelin specific genes. Neuregulin-1 (Nrg1), a member of the neuregulin family of growth factors, controls SC ...
