Description
Huntington's disease (HD) is an inherited neurodegenerative disorder of which skeletal muscle atrophy is a common feature, and multiple lines of evidence support a muscle-based pathophysiology in HD mouse models. Inhibition of myostatin signaling increases muscle mass, and therapeutic approaches based on this are in clinical development. We have used a soluble ActRIIB decoy receptor (ACVR2B/Fc) to test the effects of myostatin/activin A inhibition in the R6/2 mouse model of HD. Transcriptional profiling of muscle in treated and untreated wild-type and R6/2 mice was performed to analyze the effect of the ActRIIB decoy on genes and pathways involved in maintaining normal muscle physiology as well as those dysregulated due to the mutant HTT gene mutation. Overall design: RNAseq was performed on tibialis muscle from wild-type, wildtype + decoy, R6/2 and R6/2 + decoy; N = 10 per group. RNAseq was done on an Illumina Hi-seq 2000. Paired-end sequencing was obtained, 4-plexed across lanes for a minimum of 38 million 50mer paired reads per sample

Description
Efficient in vitro generation of hematopoietic stem cells (HSCs) from embryonic stem cells (ESCs) holds great promise for cell-based therapies of hematological diseases. To date, HoxB4 remains to be the most effective transcription factor (TF) whose over-expression in ESCs confers long-term repopulating ability to ESC-derived HSCs. Despite its importance, the components and dynamics of the HoxB4 transcriptional regulatory network is poorly understood, hindering efforts to develop a more efficient protocol for in vitro derivation of HSCs. Towards this goal, we performed global gene expression profiling and chromatin immunoprecipitation coupled with deep sequencing (ChIP-Seq) at four stages of the HoxB4-mediated HSC development. Joint analyses of ChIP-Seq and gene expression profiles unveil a number of global features of the HoxB4 regulatory network.

Description
Nonsyndromic clefts of the palate and/or lip are common birth defects arising in about 1/700 live births worldwide. They are caused by multiple genetic and environmental factors, can only be corrected surgically and require complex post-operative care that imposes significant burdens on individuals and society. Our understanding of the molecular networks that control palatogenesis has advanced through studies on mouse genetic models of cleft palate. In particular, the transcription factor Pax9 regulates palatogenesis through the Bmp, Fgf and Shh pathways in mice. But there is still much to learn about Pax9's relationship with other signaling pathways in this process. Expression analyses and unbiased gene expression profiling studies offer a molecular explanation for the resolution of palatal defects by showing that Wnt and Eda/Edar-related genes are expressed in normal palatal tissues and that the Wnt and Eda/Edar signaling pathway is downstream of Pax9 in palatogenesis. Overall design: E13.5 mouse embryos palate were micro-dissceted, control and mutant samples were seperated and individually lyzed for the RNA extraction.

Description
In murine models, we find that irradiation of Paneth cells caused a gain of a stem cell-like transcriptome and induced activation of the Notch signaling pathway. This study documents plasticity by Paneth cells, a fully committed cell population to participate in epithelial replenishment following stem cell loss. Overall design: Single-cell dissociation was carried out as previously described (Li et al., 2016; Sato et al., 2011). Cell pellets were washed with cold PBS and re-suspended in FACS buffer. Cells were stained with DAPI, PerCP/Cy5.5-conjugated EpCAM, BUV395-conjugated CD45, and APC/fire 750-conjugated CD24. Cell suspensions were subjected to sorting by BD Biosciences Aria II Flow Cytometer. Single viable intestinal epithelial cells were gated by forward scatter, side scatter, and by negative staining for DAPI and CD45, and positive staining for EpCAM. Subpopulations were further gated based on CD24 and tdTomato (using R-phycoerythrin/PE channel). Paneth cells (tdT+CD24+) and derivative (tdT+CD24-) cells were FACS-sorted from irradiated (5 days after radiation) and non-irradiated 8-14 week old Lyz1CreER; R26R-tdT mice with one dose of tamoxifen adminstration (10mg/mouse), and subjected to total RNA extraction using Qiagen RNeasy Plus Micro kit.

Nonsyndromic clefts of the palate and/or lip are common birth defects arising in about 1/700 live births worldwide. They are caused by multiple genetic and environmental factors, can only be corrected surgically and require complex post-operative care that imposes significant burdens on individuals and society. Our understanding of the molecular networks that control palatogenesis has advanced through studies on mouse genetic models of cleft palate. In particular, the transcription factor Pax9 regulates palatogenesis through the Bmp, Fgf and Shh pathways in mice. But there is still much to learn about Pax9''s relationship with other signaling pathways in this process. Here we show alterations of Wnt expression and decreased Wnt activity in Pax9-/- palatal shelves are a likely result of Pax9''s ability to directly bind and repress the promoters of Dkk1 and Dkk2, proteins that antagonize Wnt signaling. We exploited this relationship by delivering small-molecule Dkk inhibitors into the tail-veins of pregnant Pax9+/- females from E10.5 to E14.5. Such therapies restored Wnt signaling, promoted cell proliferation, bone formation and fusion of palatal shelves in Pax9-/- embryos. These data uncover a connection between the roles of Pax9 and Wnt genes in palatogenesis and offer a new approach for treating human cleft palates. Overall design: E14 embryos of Pax9-/- and control littermates with or without WAY-262611 treatment, mouse embryos palate were micro-dissected, control and mutant samples were separated and individually lysed for the RNA extraction.
