Description
Reprogramming resident glia into functional and subtype-specific neurons in vivo by delivering reprogramming genes directly to the brain provides a step forward towards the possibility of treating brain injuries or diseases. Here, we show that neurons reprogrammed using Ascl1, Lmx1a and Nurr1 functionally mature and integrate into existing brain circuitry, and that the majority of the reprogrammed neurons have properties of fast spiking, parvalbumin-containing interneurons. Overall design: A total of 6 samples were analyzed. Each sample is consists of approximately 33 laser-captured reprogrammed-neurons identified by nuclear GFP and expressing the transcription factors Ascl1, Lmx1a and Nurr1 (ALN).

Description
Global gene experssion study of the HAEC transcriptional response to artificial chlyomicron remnant-like particles (A-CRLPs) prepared with triglycerides extracted from four natural dietary oils: fish, DHASCO, corn and palm oils. We hypothesised that A-CRLPs could differentially regulate HAEC gene expression according to thier triglyceride content. These data provide an important starting point for investigations into the effects of A-CRLPs on endothelial cells, particulary genes involved in redox balance and inflammatory processes.

Description
Disrupted skin barrier due to altered keratinocyte differentiation is common in pathologic conditions such as atopic dermatitis, ichthyosis and psoriasis. However, the molecular cascades governing keratinocyte terminal differentiation are still poorly understood. We have previously demonstrated that a dominant mutation in ZNF750 leads to a clinical phenotype that reminiscent of psoriasis and seborrheic dermatitis. We defined ZNF750 as a nuclear effector that is strongly activated in and essential for keratinocyte terminal differentiation. ZNF750 knockdown in HaCaT keratinocytes markedly reduced the expression of epidermal late differentiation markers, including gene subsets of epidermal differentiation complex and skin barrier formation such as FLG, LOR, SPINK5, ALOX12B and DSG1, known to be mutated in various human skin diseases. Furthermore, ZNF750 over-expression in undifferentiated cells induced terminal differentiation genes. Thus, ZNF750 is a regulator of keratinocyte terminal differentiation, and with its downstream targets can serve in future elucidation of therapeutics for common disease of skin barrier
Publication Title
ZNF750 is expressed in differentiated keratinocytes and regulates epidermal late differentiation genes.

Description
An understanding of the mechanisms regulating white adipose tissue (WAT) formation is key for developing of new tools to treat obesity and its related diseases. Here, we identify DEPTOR as a positive regulator of adipogenesis whose expression is associated with obesity. In a polygenic mouse model of obesity/leanness, Deptor is part of the Fob3a QTL linked to obesity and we fine that Deptor is the highest priority candidate gene regulating WAT accumulation in this model. Using a doxycycline-inducible mouse model for Deptor overexpression, we confirmed that Deptor promotes WAT expansion in vivo. DEPTOR expression is elevated in WAT of obese humans and strongly correlates with the degree of obesity. We show that DEPTOR is induced during adipogenesis and that its overexpression cell-autonomously promotes, while its suppression blocks, adipogenesis. DEPTOR positively regulates adipogenesis by promoting the activity of the pro-adipogenic factors Akt/PKB and PPAR-gamma. These results establish DEPTOR as a physiological regulator of adipogenesis and provide new insights into the molecular mechanisms controlling WAT formation.

Description
Ob/ob mice were given 0, 12.5 or 25 ng/hr leptin through an osmotic pump. After 12 days, livers RNA was prepared and illumina microarrays were done. We tested whether leptin can ameliorate diabetes independent of weight loss by defining the lowest dose at which leptin treatment of ob/ob mice reduces plasma [glucose] and [insulin]. We found that a leptin dose of 12.5 ng/hour significantly lowers blood glucose and that 25 ng/hour of leptin normalizes plasma glucose and insulin without significantly reducing body weight, thus establishing that leptin exerts its most potent effects on glucose metabolism. To find possible mediators of this effect, we profiled liver mRNA using microarrays and identified IGF Binding Protein 2 as being regulated by leptin with a similarly high potency. Over-expression of IGFBP2 by an adenovirus reversed diabetes in insulin resistant ob/ob, Ay/a and diet-induced obese mice (DIO), as well as insulin deficient streptozotocin-treated mice. Hyperinsulinemic clamp studies showed a three-fold improvement in hepatic insulin sensitivity following IGFBP2 treatment in ob/ob mice. These results show that IGFBP2 can regulate glucose metabolism, a finding with potential implications for the pathogenesis and treatment of diabetes.

Description
The 16p11.2 deletion and duplication syndromes have been associated with developmental delay and autism spectrum disorders, and a reciprocal effect on body mass index. Here we explored these links with new engineered mouse models carrying a deletion (Del/+) and duplication (Dup/+) of the whole 16p11.2 homologous Sult1a1-Spn region. On a pure genetic background, compared to wild-types, Del/+ mice carrying the deletion showed weight and adipogenesis deficits, hyperactivity, repetitive behaviors, and recognition memory deficits, whereas Dup/+ mice showed the opposite phenotypes and Del/Dup individuals displayed no changes. Alterations in social interaction were also observed in Del/+ and Dup/+ animals on a mixed genetic background.
