Description
We generated Gadd45a,b,g triple-knockout mouse embryonic stem cells and performed RNA-seq expression profiling under six different conditions of cell culture and in vitro differentiation. Overall design: Gadd45a,b,g triple knockout (TKO) mouse embryonic stem cells (mESC) were generated by CRISPR/Cas9. RNA-Seq was performed to compare the transcriptome in three independent Gadd45 TKO versus three independent control mESC lines under different conditions: (i) Serum cultured mESC, (ii) Vitamin C treated mESC, (iii) 2i treated mESC, (iv) mESC differentiated as embryoid bodies (EB), (v) mESC differentiated as a serum-free monolayer, and (vi) EB stimulated with retinoic acid (RA).

Description
ING1b and GADD45a are nuclear proteins involved in the regulation of cell growth, apoptosis and DNA repair. We previously found that ING1b is required to target GADD45a-mediated active DNA-demethylation via TET1 to specific loci. In order to study the impact of ING1-GADD45a on gene expression, we compared the expression profile of wildtype mouse embryonic fibroblasts (MEFs) with Ing1- and Gadd45a- single- or double-knockout (DKO) MEFs. Overall design: Gene expression profiling in all 4 genotypes of undifferentiated MEFs in triplicates.

Description
Receptor tyrosine kinase signaling is critical for mammalian craniofacial development, but the key downstream transcriptional effectors remain unknown. We demonstrate that SRF is induced by both PDGF and FGF signaling in mouse embryonic palatal mesenchyme cells, and Srf neural crest conditional mutants exhibit facial clefting accompanied by proliferation and migration defects. Srf and Pdgfra mutants interact genetically in craniofacial development, but Srf and Fgfr1 mutants do not. This signal specificity is recapitulated at the level of cofactor activation: while both PDGF and FGF target gene promoters show enriched genome-wide overlap with SRF ChIP-seq peaks, PDGF selectively activates a network of MRTF-dependent cytoskeletal genes. Collectively, our results identify a novel role for SRF in proliferation and migration during craniofacial development and delineate a mechanism of receptor tyrosine kinase specificity mediated through differential cofactor usage, leading to a unique PDGF-responsive SRF-driven transcriptional program in the midface. Overall design: Serum Starved MEPMs (4 replicates), 1 hr PDGF treated MEPMs (4 replicates), 1 hr FGF treated MEPMs (3 replicates)

Description
Quiescent and dividing hemopoietic stem cells (HSC) display marked differences in their ability to move between the peripheral circulation and the bone marrow. Specifically, long-term engraftment potential predominantly resides in the quiescent HSC subfraction, and G-CSF mobilization results in the preferential accumulation of quiescent HSC in the periphery. In contrast, stem cells from chronic myeloid leukemia (CML) patients display a constitutive presence in the circulation. To understand the molecular basis for this, we have used microarray technology to analyze the transcriptional differences between dividing and quiescent, normal, and CML-derived CD34+ cells.

Description
An unbalanced karyotype, a condition known as aneuploidy, has a profound impact on cellular physiology and is a hallmark of cancer. Determining how aneuploidy affects cells is thus critical to understanding tumorigenesis. Here we show that aneuploidy interferes with the degradation of autophagosomes within lysosomes. Mis-folded proteins that accumulate in aneuploid cells due to aneuploidy-induced proteomic changes overwhelm the lysosome with cargo, leading to the observed lysosomal degradation defects. Importantly, aneuploid cells respond to lysosomal saturation. They activate a lysosomal stress pathway that specifically increases the expression of genes needed for autophagy-mediated protein degradation. Our results reveal lysosomal saturation as a universal feature of the aneuploid state that must be overcome during tumorigenesis. Overall design: RPE-1 cells either untreated or treated with one of Reversine, Bafilomycin A1 or MG132, each condition was done in triplicate. D14-*_Control: untreated control D14-*_Rev: cells treated with 0.5uM Reversine for 24hrs and harvested 48hrs later D14-*_Baf: cells treated with 0.1uM BafA1 for 6hrs D14-*_Mg: cells treated with 1uM MG132 for 24 hrs

Description
Transcriptional activation in mammalian embryos occurs in a stepwise manner. In mice, it begins at the late one-cell stage, followed by a minor wave of activation at the early two-cell stage, and then the major genome activation (MGA) at the late two-cell stage. Cellular homeostasis, metabolism, cell cycle, and developmental events are orchestrated before MGA by time-dependent changes in the array of maternal transcripts being translated (i.e., the translatome). Despite the importance of maternal mRNA and its correct recruitment for development, neither the array of recruited mRNA nor the regulatory mechanisms operating have been well cheracterized. We present the first comprehensive analysis of changes in the maternal component of the zygotic translatome during the transition from oocyte to late one-cell stage embryo, revealing global transitions in the functional classes of translated maternal mRNAs, and apparent changes in the underlying cis-regulatory mechanisms.
