BACKGROUND The neuroprotective and trophic actions of erythropoietin (EPO) have been tested in several animal models of insult, injury, and neurodegeneration. Recent studies in human volunteers demonstrated that EPO improves cognition and also elicits antidepressant effects. It is believed that the behavioral effects are mediated by EPO's trophic effect on(More)
ZNF804a was identified by a genome-wide association study (GWAS) in which a single nucleotide polymorphism (SNP rs1344706) in ZNF804a reached genome-wide statistical significance for association with a combined diagnosis of schizophrenia (SZ) and bipolar disorder. Although the molecular function of ZNF804a is unknown, the amino acid sequence is predicted to(More)
BACKGROUND Despite recent interest in glycogen synthase kinase-3beta (GSK-3beta) as a target for the treatment of mood disorders, there has been very little work related to these illnesses on the upstream signaling molecules that regulate this kinase as well as downstream targets. METHODS With a focused microarray approach we examined the influence of(More)
BACKGROUND Variants in dyslexia-associated genes, including DCDC2, have been linked to altered neocortical activation, suggesting that dyslexia associated genes might play as yet unspecified roles in neuronal physiology. METHODS Whole-cell patch clamp recordings were used to compare the electrophysiological properties of regular spiking pyramidal neurons(More)
Alterations in gene expression in the dorsal striatum caused by chronic cocaine exposure have been implicated in the long-term behavioral changes associated with cocaine addiction. To gain further insight into the molecular alterations that occur as a result of cocaine self-administration, we conducted a microarray analysis of gene expression followed by(More)
Electroconvulsive seizure has a proven therapeutic application in the treatment of severe depression and treatment-resistant depression. Despite the efficacy of electroconvulsive seizure as a non-chemical antidepressant treatment, the mechanism of action is unclear. Elevation in hippocampal trophic factor expression and concomitant cellular proliferation(More)
The role of the choroid plexus (CP) in brain homeostasis is being increasingly recognized and recent studies suggest that the CP has a more important role in physiological and pathological brain functions than currently appreciated. To obtain additional insight on the CP function, we performed a proteomics and transcriptomics characterization employing a(More)
The molecular mechanism of action of antipsychotic drugs is not well understood. Their complex receptor affinity profiles indicate that their action could extend beyond dopamine receptor blockade. Single gene expression studies and high-throughput gene profiling have shown the induction of genes from several molecular classes and functional categories.(More)
Many of the mitoses that produce pyramidal neurons in neocortex occur at the dorsolateral surface of the lateral ventricles in the embryo. RanBPM was found in a yeast two-hybrid screen to potentially interact with citron kinase (CITK), a protein shown previously to localize to the surface of the lateral ventricles and to be essential to neurogenic mitoses.(More)
Degradation of the vascular basement membrane stimulates angiogenesis and is tightly controlled by balancing the actions of metalloproteases and their inhibitors. Previous work demonstrated that electroconvulsive seizure (ECS) elevates angiogenic factors and endothelial proliferation in the hippocampus. The robust induction of tissue inhibitor of matrix(More)
