Description
Little is known about the roles of methyl-CpG-binding domain protein 2 (MBD2), a reader of DNA methylation, in T-cell acute lymphoblastic leukemia (T-ALL). Here, we investigated the role of MBD2 in T-ALL by using an Mbd2 knockout mouse model. We found that MBD2 ablation impeded the progression and maintenance of Notch1-driven T-ALL.Our data reveals essential roles for MBD2 in lymphopoiesis and T-ALL and support an intriguing potential of MBD2 as a therapeutic target for T-ALL.

Description
In the early zebrafish embryo, the developing genome profile can be interfered with by exposure to pentachlorophenol, and some specific sets of genes are up-regulated or down-regulated. We used microarrays to detail the global program of gene expression underlying cellularisation and identified distinct classes of up-regulated genes during this process.

Description
Neural crest defects lead to congenital heart disease involving outflow tract (OFT) malformation. Integrin-linked-Kinase (ILK) plays important roles in multiple cellular processes and embryogenesis. ILK is expressed in neural crest cells (NCC), but its role in NCC and OFT morphogenesis remains unknown.

Description
While the functional roles of long non-coding RNAs (lncRNAs) have been increasingly identified, few lncRNAs that control the naive state of embryonic stem cells (ESCs) are known. Here, we report a naive-state-associated lncRNA, lincU, which is intrinsically activated by NANOG in naive mESCs. LincU-deficient mESCs exhibit a primed-like pluripotent state and potentiate the transition from naive state to primed state, whereas ectopic lincU expression maintains mESCs in the naive state. Mechanistically, we demonstrate that lincU directly binds and stabilizes the DUSP9 protein, an ERK-specific phosphatase, and then constitutively inhibits the ERK1/2 signaling pathway, which critically contributes to maintenance of the naive state. Importantly, we reveal the functional role of lincU to be evolutionarily conserved in human. Our findings thus unveil lincU as a conserved lncRNA that intrinsically restricts MAPK/ERK activity and maintains the naive state of ESCs.

Sin3a, a known master scaffold, provides unique contact surfaces for interaction with particular accessory proteins to repress the transcription of specific genes. Surprisingly, our results also suggest that Sin3a has a role in transcriptional activation.

We performed gene-expression analysis of mouse Purkinje cells as a model single-type neuron. DNA microarray analysis detected at least 7,055 genes in Purkinje cells, most of which are classified into functional molecule categories.

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.
