Description
Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed antidepressant drugs in pregnant women. Given that SSRIs can cross the placental and blood-brain barriers, these drugs potentially affect serotonergic neurotransmission and neurodevelopment in the fetus. Although no gross SSRI-related teratogenic effect has been reported, infants born following prenatal exposure to SSRIs have a higher risk for various behavioral abnormalities. Therefore, we examined the effects of prenatal fluoxetine, the most commonly prescribed SSRI, on social and cognitive behavior in mice. Intriguingly, chronic in utero fluoxetine treatment impaired working memory and social novelty recognition in adult males with augmented spontaneous inhibitory synaptic transmission onto the layer 5 pyramidal neurons in the medial prefrontal cortex (mPFC). Moreover, fast-spiking interneurons in the layer 5 mPFC exhibited enhanced basal intrinsic excitability, augmented serotonin-induced neuronal excitability, and increased inhibitory synaptic transmission onto the layer 5 pyramidal neurons due to augmented 5-HT2A receptor (5-HT2AR) signaling. More importantly, the observed behavioral deficits of in utero fluoxetine-treated mice could be reversed by acute systemic application of 5-HT2AR antagonist. Taken together, our findings support the notion that alterations in serotonin-mediated inhibitory neuronal modulation result in reduced cortical network activities and cognitive impairment following prenatal exposure to SSRIs.

Gene expression microarrays were performed to investigate the molecular effects of exposure to environmental polluted groundwater. Zebrafish was treated with polluted waters collected from dumps located upstream and downstream a sanitary landfills. Gene expression profiling of zebrafish liver was analyzed after acute exposure to sampled waters.

Description
This study aimed to investigate the effects of depression on transcriptome in ileum using a subchronic and mild social defeat stress (sCSDS) model. In addition to exhibiting social deficit and hyperphagia-like behavior, the sCSDS mice keep much more water in their body than control mice. In order to investigate the effect of social defeat stress on not only central nervous system but also function of gastrointestinal tract, the gene expression in ileum of stressed mice was compared with control mice.

Description
Stem-cells and transformed cancer cells specifically express a polycomb repressive complex subtype, PRC4 which characteristically contains Sirt1 (Sirtuin-1), a NAD+ dependent class III histone deacetylase (HDAC) and Eed2 isoform as specific members. Analyzing the transcriptiome and methylome analysis of Sirt1 deficient murine ESCs (Sirt1-/- ESC), we demonstrate that these cells repressed specifically on some genomic imprinted and germ-line related genes.

Description
L-3,4-dihydroxyphenylalanine (levodopa) treatment is the major pharmacotherapy for Parkinson's disease. However, almost all patients receiving levodopa eventually develop debilitating involuntary movements (dyskinesia). While it is known that striatal spiny projection neurons (SPNs) are involved in the genesis of this movement disorder, the molecular basis of dyskinesia is not understood. In this study, we identify distinct cell-type-specific gene expression changes that occur in sub-classes of SPNs upon induction of a parkinsonian lesion followed by chronic levodopa treatment. We identify several hundred genes whose expression is correlated with levodopa dose, many of which are under the control of AP-1 and ERK signaling. In spite of homeostatic adaptations involving several signaling modulators, AP-1-dependent gene expression remains highly dysregulated in direct pathway SPNs (dSPNs) upon chronic levodopa treatment. We also discuss which molecular pathways are most likely to dampen abnormal dopaminoceptive signaling in spiny projection neurons, hence providing potential targets for antidyskinetic treatments in Parkinson's disease.
