Description
Cumulus cells (CCs) are biologically distinct from other follicular cells and perform specialized roles, transmitting signals within the ovary and supporting oocyte maturation during follicular development. The Affymetrix 3 IVT express protocol was used to prepare cRNA (one-cycle amplification) with a starting concentration of 100 ng of total RNA

Description
In humans, the embryonic genome activation (EGA) program is functional by day 3 after fertilization. The 6-8 cell stage embryo (day 3 post-fertilization) starts the process of compaction that leads to the generation of the tightly organized cell mass of the morula and is followed by differentiation of the morula into a blastocyst. The transition from day 3 embryos to day 5 blastocysts is likely to be controlled by many and specific changes in the expression of different genes. We used mRNA amplification technique and compared the transcriptomes of day 3 human embryos and trophectoderm (TE) cells from day 5 human blastocysts to identify transcripts that are differentially expressed during the embryo-to-TE transition and involved in the TE specification.

Description
The trophoblast cell lineage is specified as early as the blastocyst stage, leading to the individualization of trophectoderm from pluripotent cells of the inner cell mass. We used a double in vitro transcription mRNA amplification technique and compared trophectoderm with pluripotent stem cells.

Description
Cumulus cells are biologically distinct from other follicular cells and perform specialized roles, transmitting signals within the ovary and supporting oocyte maturation during follicular development. The bi-directional communication between the oocyte and the surrounding cumulus cells is crucial for the acquisition of oocyte competence. Using Illumina/deep-sequencing technology, we dissected the small RNAome of pooled human mature MII oocytes and cumulus cells. Overall design: Cumulus cells and MII mature oocytes small RNA profiles were generated by deep-sequencing, using Illumina 1G sequencer

Description
N6-methyladenosine (m6A) has been recently identified as a conserved epitranscriptomic modification of eukaryotic mRNAs, but its features, regulatory mechanisms, and functions in cell reprogramming are largely unknown. Here, we report m6A modification profiles in the mRNA transcriptomes of four cell types with different degrees of pluripotency. Comparative analysis reveals several features of m6A, especially gene- and cell-type-specific m6A mRNA modifications. We also show that microRNAs (miRNAs) regulate m6A modification via a sequence pairing mechanism. Manipulation of miRNA expression or sequences alters m6A modification levels through modulating the binding of METTL3 methyltransferase to mRNAs containing miRNA targeting sites. Increased m6A abundance promotes the reprogramming of mouse embryonic fibroblasts (MEFs) to pluripotent stem cells; conversely, reduced m6A levels impede reprogramming. Our results therefore uncover a role for miRNAs in regulating m6A formation of mRNAs and provide a foundation for future functional studies of m6A modification in cell reprogramming. Overall design: m6A-seq in ESC, iPSC, NSC and sertoli cells.

Description
Total RNA-seq analysis of mouse liver following LNA treatment in vivo to identify mRNA targets of mmu-miR-802-5p and mmu-miR-1948-5p. Overall design: Male and female 9-wk ICR mice were injected with LNAs complementary to mmu-miR-1948-5p and mmu-miR-802-5p, respectively. Liver RNA was analyzed by RNA-seq 3 days or 6 days after LNA treatment.

Description
The inflammatory response plays out over time in a reproducible and organized manner after an initiating stimulus. Here we showed that the genes activated in cultured mouse fibroblasts in response to the proinflammatory cytokine tumor necrosis factorcan be divided roughly into three groups, each with different induction kinetics. Whereas differential transcription is important in determining the grouping of these genes, differential mRNA stability also exerted strong influence in some cases overriding that of transcriptional control elements on the temporal order of gene expression. mRNA transcripts expressed early after TNF stimulation have abundant AU-rich elements in their 3'-untranslated regions whereas those expressed later are contain fewer AU-rich sequences. Thus mRNA stability and transcriptional control, two intrinsic characteristics of genes, control the kinetics of proinflammatory cytokine-induced gene expression.

Description
High amount of Eomes might drive T cell exhaustion. In order to understand how Eomes contributes to exhaustion of CD8+ T cell in the TME, we conducted transcriptional analysis of control OT-I cells and Eomes-overexpressing OT-I cells Overall design: Eomes was cloned into a retroviral expression vector (RVKM) which also encodes an IRES-hCD2 cassette. This vector was transfected into Pheonix to package retrovirus. The empty vector was used as a control. CD8+ T cells were isolated from spleen and lymph nodes of OT-I mice using Dynabeads Flowcomp mouse CD8 kit (Invitrogen). Then the cells were stimulated with SIINFEKL peptide (OVA257-264) at 2.5 ng/mL in the presence of 10U/mL IL-2 for 24 hr. Retroviral supernatants were harvested, filtered, and supplemented with 6µg/mL polybrene. OT-I T cell cultures were spinduced with the retroviral supernatant for 90 min at 1800 rpm, 32ºC. 48 hr later, hCD2+ cells were sorted prior to re-stimulation. hCD2+ OT-I cells were plated at 40,000 cells/well in 96-well plates and re-stimulated with 2.5ng/mL OVA with 10U/mL IL-2 for 3 days before harvested for RNAseq analysis. Total RNA was extracted from re-stimulated control or Eomes-overexpressing OT-I cells and sent to BGI Genomics for library construction. The library products were sequenced via Illumina Hiseq4000 by BGI Genomics. The sequencing reads were filtered by SOAPnuke without quality problems. Genome mapping was done by HISAT. Clean reads were mapped to the mm10 reference genome using Bowtie2, and gene expression indicated by RPKM (Reads Per Kilobases per Million reads) was calculated by RSEM. Differentially expressed genes (DEG) were detected with PoissonDis by at least 1.5 fold change and FDR lower than 0.01.
