BACKGROUND Neuregulin1 (NRG1)-ErbB signaling has been implicated in the pathogenesis of cancer and schizophrenia. We have previously reported that NRG1-stimulated migration of B lymphoblasts is PI3K-AKT1dependent and impaired in patients with schizophrenia and significantly linked to the catechol-o-methyltransferase (COMT) Val108/158Met functional polymorphism. METHODOLOGY/PRINCIPAL FINDINGS ...

BACKGROUND We previously developed and validated a strategy for stimulating heart regeneration by administration of recombinant neuregulin (rNRG1), a growth factor, in mice. rNRG1 stimulated proliferation of heart muscle cells, cardiomyocytes, and was most effective when administration began during the neonatal period. Our results suggested the use of rNRG1 to treat pediatric patients with hear...

Muscle spindles are sensory receptors composed of specialized muscle fibers, known as intrafusal muscle fibers, along with the endings of sensory neuron axons that innervate these muscle fibers. Formation of muscle spindles requires neuregulin1 (NRG1), which is released by sensory axons, activating ErbB receptors in muscle cells that are contacted. The transcription factor Egr3 is transcription...

Muscle spindles are sensory receptors embedded within muscle that detect changes in muscle length. Each spindle is composed of specialized muscle fibers, known as intrafusal muscle fibers, along with the endings of axons from sensory neurons that innervate these muscle fibers. Formation of muscle spindles requires neuregulin1 (NRG1), which is released by sensory axons, activating ErbB receptors...

OBJECTIVE Neuregulin1 (NRG1) gene is among the most promising candidate genes for schizophrenia. This gene is located on 8p22-p12, a region with a reported linkage to schizophrenia. Several studies have reported an association between schizophrenia and the 5' end polymorphisms in this gene. However, some studies have failed to confirm the role of NRG1 gene in the pathogenesis of schizophrenia. ...

During peripheral nervous system development, successful communication between axons and Schwann cells is required for proper function of both myelinated and nonmyelinated nerve fibers. Alternatively spliced proteins belonging to the neuregulin1 (NRG1) gene family of growth and differentiation factors are essential for Schwann cell survival and peripheral nerve development. Although recent stud...

Antiestrogens, such as tamoxifen, are widely used for endocrine treatment of estrogen receptor-positive breast cancer. However, as breast cancer progresses, development of tamoxifen resistance is inevitable. The mechanisms underlying this resistance are not well understood. To identify genes involved in tamoxifen resistance, we have developed a rapid screening method. To alter the tamoxifen-sen...

objective: neuregulin1 (nrg1) gene is among the most promising candidate genes for schizophrenia. this gene is located on 8p22-p12, a region with a reported linkage to schizophrenia. several studies have reported an association between schizophrenia and the 5′ end polymorphisms in this gene. however, some studies have failed to confirm the role of nrg1 gene in the pathogenesis of schizophrenia....

Schizophrenia is one of the most devastating psychiatric disorders. Schizophrenia affects 1.1% of the population or 51 million people (NIMH). Schizophrenia is a disorder that affects multiple brain regions and systems. Symptoms include positive symptoms, negative symptoms and cognitive deficits. Much research has focused on two neurotransmitter systems, dopamine and glutamate. Postmortem studie...
