Estrogen modifies human emotion and cognition and impacts symptoms of schizophrenia. We hypothesized that the variation in the estrogen receptor alpha (ESR1) gene and cortical ESR1 mRNA is associated with schizophrenia. In a small case-control genetic association analysis of postmortem brain tissue, genotype CC (rs2234693) and haplotypes containing the C(More)
In this study, we determined when and through which promoter brain-derived neurotrophic factor (BDNF) transcription is regulated during the protracted period of human frontal cortex development. Using quantitative real-time polymerase chain reaction, we examined the expression of the four most abundant alternative 5' exons of the BDNF gene (exons I, II, IV,(More)
The truncated brain-derived neurotrophic factor (BDNF) receptors (truncated TrkB [TrkB-TK-] and sarc homology containing TrkB [TrkB-Shc]) are alternative transcripts of the full-length TrkB receptor (TrkB-TK+) that produce isoforms capable of binding to BDNF but not being able to mediate the classic neurotrophic response via tyrosine kinase signaling. We(More)
Brain-derived neurotrophic factor and neurotrophin-4 high-affinity receptor tropomyosine related kinase (Trk) B is required for the differentiation and maintenance of specific neuron populations. Misregulation of TrkB has been reported in many human diseases, including cancer, obesity and neurological and psychiatric disorders. Alternative splicing that(More)
AIM The effects of 24(S),25-epoxycholesterol (24,25EC) on aspects of cholesterol homeostasis is well-documented. When added to cells, 24,25EC decreases cholesterol synthesis and up-regulates cholesterol efflux genes, including ABCA1. Synthesis of 24,25EC occurs in a shunt of the mevalonate pathway which also produces cholesterol. Therefore, 24,25EC(More)
OBJECTIVE While schizophrenia may have a progressive component, the evidence for neurodegenerative processes as indicated by reactive astrocytes is inconclusive. We recently identified a subgroup of individuals with schizophrenia with increased expression of inflammatory markers in prefrontal cortex, and hypothesized that this subgroup would also have(More)
BACKGROUND/AIMS Dysregulation of pre-mRNA splicing from an altered expression of RNA splice-regulatory proteins may act as the convergence point underlying aberrant gene expression changes in Alzheimer's disease (AD). METHODS Two microarray datasets from a control/AD postmortem brain cohort of 31 subjects - 9 controls and 22 AD subjects (National Center(More)
Tropomyosin receptor kinase B (TrkB) is best known as the receptor for brain-derived neurotrophic factor (BDNF). In humans, three major isoforms of TrkB, the full-length receptor (TrkB-TK+) and two C-terminal truncated receptors (TrkB-TK- and TrkB-Shc) are expressed in various tissues. In comparison to TrkB-TK+ and TrkB-TK-, TrkB-Shc is less well(More)
BACKGROUND/AIMS Tropomyosin-related kinase B receptor (TrkB)-mediated signaling is vital for neuronal differentiation, survival, plasticity, and cognition. In this study, the focus was placed on TrkB-Shc, a neuron-specific transcript, to determine if microRNAs (miRNAs) play a role in TrkB-Shc regulation. METHODS A combination of bioinformatics and(More)
