Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The identification of the most appropriate T-cell subset to ensure optimal persistence and anti-tumor activity is a major goal of cancer immunotherapy. We identified a novel post-mitotic CD45RA+CD62L+ T cell subpopulation (TTN), generated in vitro upon activation of nave T (TN) cells with beads conjugated to anti-CD3 and anti-CD28 antibodies. This cell population is highly proliferative, produces low levels of IFNg and cytotoxic molecules, and requires IL-7 and IL-15 for in vitro expansion.

A supplementary Excel workbook holding the same processed data as the series matrix file is provided, with some probe set annotation, and a simple statistical comparison. The raw (.CEL) files are also provided.

Description
Hepatocellular carcinoma (HCC) accounts for the majority of malignant liver tumors and results in many deaths each year, emphasizing the need for new therapies. The protein-protein interaction between menin and histone methyltransferase Mixed Lineage Leukemia 1 (MLL1) plays an important role in the development of HCC, implying that pharmacologic inhibition of this interaction could lead to new therapeutic strategy for the HCC patients. Therefore, we performed RNA sequencing experiment to determine the transcriptome change in the HepG2 cells upon treatment of MI-503, a small molecule inhibitor of the menin-MLL1 interaction with optimized drug-like properties Overall design: HepG2 cells were plated in the 12-well plates at the initial concentration of 0.4x106 cells/ml and treated with 3 µM MI-503 or DMSO (0.25%) in triplicates. After 3 days of treatment viable cell number was adjusted to the original concentration in the DMSO treated samples and the same dilution factor was used to adjust cell number in the MI-503 treated cells. Media was changed and compound or DMSO was re-supplied at that time. Cells were harvested after 3 more days of incubation.

Description
We compare the performance of two library preparation protocols (poly(A) and exome capture) in in vitro degraded RNA samples Overall design: VcaP cell were grown, and treated with MDV3100 (enzalutamide) or DHT (dihydrotestosterone), intact RNA was isolated and samples were prepared in technical triplicates using two library preparation protocol. Also cells were subject to in vitro degradation through incubation of the whole cell lysate in 37C for increasing amounts of time. Following incbation paired capture and poly(A) libraries were prepared.

Description
The Polymerase Associated Factor (PAFc) complex is an epigenetic regulating complex that has been shown to to be important for Acute Myeloid Leukemias harboring an MLL chromosomal translocations, such as MLL-AF9 leukemias. This study describes the transcriptomic profiling of AML cells following genetic deletion of the PAFc subunit Cdc73. Overall design: Cdc73floxed cells were transformed to an AML using MLL-AF9 oncogene transduction. The cells were also transduced with a 4OHT inducible CreER. The cells were then treated for 24 or 48 hours with 4OHT to induce genetic excision of Cdc73 and polyA mRNA was isolated for sequencing of the transcriptome. Biological duplicates are labelled _1 and _2.

Description
The quality of maternal care in early-life plays a crucial role in mammalian neurodevelopment. Augmented maternal care (AMC) is a well-established rodent model of enhanced neonatal care. Rats that have undergone AMC have improved stress resilience and cognition compared with rats that have experienced normal levels of maternal care or adverse neonatal stress. However, the epigenomic basis of long-lived responses to AMC has not been previously explored. Thus, we employed whole-genome bisulfite sequencing (WGBS), RNA-sequencing (RNA-seq), and a multiplex microRNA (miRNA) assay to assess DNA cytosine methylation, gene expression, and miRNA expression, respectively. The integrated results identify a suite of 20 prioritized candidates impacted by AMC. Overall, these results identified AMC-induced regulatory differences in genes related to neurotransmission, neurodevelopment, protein synthesis, and oxidative phosphorylation in addition to the expected stress response genes. Together, these unbiased results represent a key progression in understanding the complex mechanisms underlying the early-life mechanisms for AMC programming stress resiliency. Overall design: DNA methylation and RNA were assayed in augmented maternal care male rats as well as controls.

Description
Whereas the cellular basis of the hematopoietic stem cell (HSC) niche in the bone marrow has been characterized, the nature of the fetal liver (FL) niche is not yet elucidated. We show that Nestin+NG2+ pericytes associate with portal vessels, forming a niche promoting HSC expansion. Nestin+NG2+ cells and HSCs scale during development with the fractal branching patterns of portal vessels, tributaries of the umbilical vein. After closure of the umbilical inlet at birth, portal vessels undergo a transition from Neuropilin-1+Ephrin-B2+ artery to EphB4+ vein phenotype, associated with a loss of peri-portal Nestin+NG2+ cells and emigration of HSCs away from portal vessels. These data support a model in which HSCs are titrated against a peri-portal vascular niche with a fractal-like organization enabled by placental circulation. Overall design: Characterization of the transcriptome of fetal liver and adult bone marrow niche using RNA-seq

Description
The most recurrently mutated oncogene in T-cell acute lymphoblastic leukemia (T-ALL) is NOTCH1. The core Notch complex consists of an ICN protein, a Maml cofactor, and the DNA binding factor Rbpj. The known direct cofactors of Notch appear to act nonselectively, homogeneously driving Notch gene expression functions. It is unclear whether there are direct cofactors of Notch that act selectively and heterogeneously regulate ICN. We discovered that Zmiz1, a Protein Inhibitor of Activated STAT (PIAS)-like coactivator, directly bound ICN1. ChIP-Seq showed that Zmiz1 selectively co-bound only a subset of Notch-regulated enhancers. This led to hypothesize that Zmiz1 regulates only a subset of Notch1 target genes. To investigate this, we performed RNA-Seq on four 8946 cell linesin which L1601P (activated Notch1) or Zmiz1 were expressed alone or in combination. Zmiz1 induced ~10% of Notch target genes. The Notch target gene that was most strongly induced by Zmiz1 was Myc. Our data suggest that Zmiz1 selectively amplifies a subset of Notch target genes with strong amplification of Myc. Overall design: RNA-Seq in a murine T-ALL cell line

Description
The proper mammalian oocytes maturation is recognized as reaching MII stage and accumulation of mRNA and proteins in cell cytoplasm following fertilization. The proper course of folliculogenesis and oogenesis is orchestrated with morphogenesis significantly influencing further zygote formation and embryos growth. This study was aimed to determinate new transcriptomic markers of porcine oocytes morphogenesis associated with cell maturation capacity.
