Differential display of mRNA was used to identify concordant changes in gene expression induced by two mood-stabilizing agents, lithium and valproate (VPA). Both treatments, on chronic administration, increased mRNA levels of the transcription factor polyomavirus enhancer-binding protein (PEBP) 2beta in frontal cortex (FCx). Both treatments also increased(More)
The mood-stabilizing agents lithium and valproic acid (VPA) increase DNA binding activity and transactivation activity of AP-1 transcription factors, as well as the expression of genes regulated by AP-1, in cultured cells and brain regions involved in mood regulation. In the present study, we found that VPA activated extracellular signal-regulated kinase(More)
The prefrontal cortex is a higher brain region that regulates thought, behavior, and emotion using representational knowledge, operations often referred to as working memory. We tested the influence of protein kinase C (PKC) intracellular signaling on prefrontal cortical cognitive function and showed that high levels of PKC activity in prefrontal cortex, as(More)
Glutamatergic signaling through N-methyl-D-aspartate receptors (NMDARs) is required for synaptic plasticity. Disruptions in glutamatergic signaling are proposed to contribute to the behavioral and cognitive deficits observed in schizophrenia (SZ). One possible source of compromised glutamatergic function in SZ is decreased surface expression of(More)
Bipolar affective disorder is a severe and debilitating psychiatric condition characterized by the alternating mood states of mania and depression. Both the molecular pathophysiology of the disorder and the mechanism of action of the mainstays of its treatment remain largely unknown. Here, (1)H NMR spectroscopy-based metabonomic analysis was performed to(More)
Valproic acid (VPA) is a potent broad spectrum anticonvulsant with demonstrated efficacy in the treatment of Bipolar Affective Disorder, but the biochemical basis for VPA's antimanic or mood-stabilizing actions have not been fully elucidated. It has been demonstrated that VPA, at therapeutically relevant concentrations, increases AP-1 DNA binding activity(More)
BACKGROUND Triple-negative breast cancer (TNBC) may be more sensitive to platinum. This study was to compare platinum-based regimen with nonplatinum regimen in the first-line treatment of advanced TNBC. PATIENTS AND METHODS Eligible metastatic TNBC (mTNBC) women without prior treatment for advanced disease were randomized (1 : 1) to receive either(More)
Valproic acid (VPA), a simple branched fatty acid anticonvulsant, has been demonstrated to have clinical efficacy in the treatment of manic-depressive illness (Bowden et al., 1994), but the mechanism(s) by which VPA produces its therapeutic effects remain to be elucidated. VPA's clinical antimanic action require a lag period for onset and are not(More)
The aim of this study was to evaluate the role of GSTM1 null/present, GSTT1 null/present, and GSTP1 polymorphisms in the clinical response to chemotherapy and treatment outcome of breast cancer. The GSTM1, GSTT1, and GSTP1 IIe105Val polymorphism genotypes were analyzed using polymerase chain reaction coupled with restriction fragment length polymorphism.(More)
Lithium, a monovalent cation, is the mainstay in the treatment of manic-depressive (MDI) illness, but despite extensive research, its mechanism of action remains to be elucidated. Since lithium requires chronic administration for therapeutic efficacy, and because its beneficial effects last well beyond its discontinuation, it has been postulated that(More)
