Description
Neural stem cells (NSC) derived from human parthenogenic stem cells (hpSC) have been observed to show stronger positive functional effects than hpSC-derived dopaminergic neuron precursors (DAP) in treatment of induced Parkinson Disease in animal models. RNAseq of the two types of cells were normalized and analyzed to compare gene expression profiles. Overall design: cDNA library of hpsC, NSC and DAP triplicates were sequenced using Illumina HiSeq 2000. The sequence reads were mapped to hg19 reference genome and hits that passed quality filters were analyzed for differential expression.

Description
The study of mammalian development has offered many insights into the molecular aetiology of cancer. We previously used analysis of mammary morphogenesis to discover a critical role for GATA-3 in mammary developmental and carcinogenesis. In recent years an important role for MicroRNAs (miRNAs) in a myriad of cellular processes in development and in oncogenesis has emerged. In this study, microRNA profiling of stromal and epithelial cellular subsets microdissected from the developing mouse mammary gland revealed many microRNAs with expression restricted to various cellular subsets. MicroRNA-184 (miR-184) was exclusively expressed in epithelial cells and markedly upregulated during differentiation of the proliferative, invasive cells of the pubertal terminal end bud (TEB) into ductal epithelial cells in vivo and in FACS-sorted mammary stem cells (MaSCs) versus luminal epithelial cells. miR-184 expression was silenced in mouse tumour models compared to non-transformed epithelium and in a majority of breast cancer cell line models. Ectopic reactivation of miR-184 inhibited the proliferation and self-renewal of metastatic triple negative breast cancer (TNBC) cell lines in vitro and delayed tumour formation and reduced metastasis in vivo. Gene expression studies uncovered multi-factorial direct regulation of genes in the AKT/mTORC1 pathway by miR-184. In clinical breast cancer tissues, expression of miR-184 is lost in primary TNBCs while the miR-184 promoter is methylated in a subset of lymph node metastases from TNBC patients. These studies elucidated a new layer of regulation in the PI3K/AKT/mTOR pathway with relevance to mammary development and tumour proliferation and metastasis.

Description
Genetically encoded unnatural amino acids provide powerful strategies for modulating the molecular functions of proteins in mammalian cells. However this approach has not been coupled to genome-wide measurements, because efficient unnatural amino acid incorporation is limited to readily transfectable cells and leads to very heterogeneous expression. We demonstrate that rapid piggybac integration of the orthogonal pyrrolysyl-tRNA synthetase (PylS)/tRNAPyl CUA pair (and its derivatives) into the mammalian genome enables efficient, homogeneous unnatural amino acid incorporation into target proteins in diverse cells, and we reveal the distinct transcriptional responses of ES cells and MEFs to amber suppression. Genetically encoding Ne-acetyl-lysine in place of six lysine residues in histone H3, that are known to be post-translationally acetylated, enables deposition of pre-acetylated histones into cellular chromatin, via a synthetic pathway that is orthogonal to enzymatic modification, allowing us to determine the consequences of acetylation at specific amino acids in histones on gene expression. Overall design: mRNA was sequenced using polyA-enrichment and Truseq library preparation protocol. Two biological replicates were sequences for each cell line and condition

Description
Thyroid hormone has a positive effect on endochondral bone growth. Few studies have looked at the interaction between thyroid hormone exposures and intramembranous bone derived cells. We used microarray as one tool to determine the gene expression profile of intramembranous (calvarial) derived murine pre-osteoblsts after thyroxine exposure.

Description
Endogenous retroviruses (ERVs) have provided an evolutionary advantage in the diversification of transcript regulation and are thought to be involved in the establishment of extraembryonic tissues during development. However, silencing of these elements remains critical for the maintenance of genome stability. Here, we define a new chromatin state that is uniquely characterized by the combination of the histone variant H3.3 and H3K9me3, two chromatin ‘marks’ that have previously been considered to belong to fundamentally opposing chromatin states. H3.3/H3K9me3 heterochromatin is fundamentally distinct from ‘canonical’ H3K9me3 heterochromatin that has been under study for decades and this unique functional interplay of a histone variant and a repressive histone mark is crucial for silencing ERVs in ESCs. Our study solidifies the emerging notion that H3.3 is not a histone variant associated exclusively with “active” chromatin and further suggests that its incorporation at unique heterochromatic regions may be central to its function during development and the maintenance of genome stability. Overall design: RNA-seq analysis of three embryonic stem cell lines WT, H3.3 KO1, and H3.3 KO2)

Description
To address the role of INO80/SWR-type remodeling complexes, we deleted Ep400 at defined times of mouse oligodendrocyte development. Whereas oligodendrocyte precursors are specified and develop normally without Ep400, terminal differentiation is dramatically impaired resulting in hypomyelination. RNA-Seq studies were performed on cultured and FACS sorted control and Ep400-deficient mouse oligodendrocytes to analyze changes in gene expression. These revealed that genes associated with the myelination program and with response to DNA damage are altered in Ep400-deficient oligodendrocytes. Overall design: OPC mRNA profiles of 6-day old control (ctrl) and Ep400 cko mice were generated using the Illumina HiSeq 2500 platform.
