Phenotypic Characterization of Transgenic Mice Overexpressing Neuregulin-1
BACKGROUND Neuregulin-1 (NRG1) is one of the susceptibility genes for schizophrenia and implicated in the neurotrophic regulation of GABAergic and dopaminergic neurons, myelination, and NMDA receptor function. Postmortem studies often indicate a pathologic association of increased NRG1 expression or signaling with this illness. However, the psychobehavioral implication of NRG1 signaling has mai...
متن کاملCraniosynostosis in transgenic mice overexpressing Nell-1.
Previously, we reported NELL-1 as a novel molecule overexpressed during premature cranial suture closure in patients with craniosynostosis (CS), one of the most common congenital craniofacial deformities. Here we describe the creation and analysis of transgenic mice overexpressing Nell-1. Nell-1 transgenic animals exhibited CS-like phenotypes that ranged from simple to compound synostoses. Hist...
متن کاملGalanin overexpressing transgenic mice.
Galanin overexpressing transgenic mice (GAL-tg) were generated on two different promoters. Both lines of GAL-tg displayed high levels of galanin in the hippocampus and reduced sensitivity to seizures, as compared to their respective wildtype littermate controls (WT). Performance deficits on learning and memory tasks, impaired long-term potentiation, reduced hippocampal excitability, lower evoke...
متن کاملReversal of Behavioral Deficits and Synaptic Dysfunction in Mice Overexpressing Neuregulin 1
Neuregulin 1 (Nrg1) is a susceptibility gene of schizophrenia, a disabling mental illness that affects 1% of the general population. Here, we show that ctoNrg1 mice, which mimic high levels of NRG1 observed in forebrain regions of schizophrenic patients, exhibit behavioral deficits and hypofunction of glutamatergic and GABAergic pathways. Intriguingly, these deficits were diminished when NRG1 e...
متن کاملmpaired relaxation in transgenic mice overexpressing junctin
Objective: Junctin is a major transmembrane protein in cardiac junctional sarcoplasmic reticulum, which forms a quaternary complex 21 with the ryanodine receptor (Ca release channel), triadin, and calsequestrin. Methods: To better understand the role of junctin in excitation–contraction coupling in the heart, we generated transgenic mice with targeted overexpression of junctin to mouse heart, u...
