Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Human umbilical vein endothelial cells (HUVECs) formed capillary structures when co-cultured with normal human dermal fibroblasts (NHDFs). HUVEC competence and NHDF supportiveness of cord formation were found to be highly cell-passage dependent with the early passage cells forming more angiogenic cord structures. We thus profiled gene expression in NHDFs with different passages to understand the molecular mechanisms underlying the in vitro angiogenesis control.

Description
HCT116 cells were treated with with increasing concentrations of trametinib over 2 months. Drug-resistant clones emerged and were cultured in the presence of 30 nmol/L trametinib. These cells exhibited a greater than 10-fold increase in the GI50 for trametinib compared to the parental cell line. RNA-seq of the resistant clone HCT116_R4 versus the parental cells identified differentially expressed genes potentially involved in resistance. Overall design: For the parental and resistant clone, 3 replicates each were analysed by RNA-seq.

- Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Protein deficiency and intestinal parasite infection during pregnancy impair fetal growth through passage of signals from the maternal environment which signal impairment of fetal growth. The placenta is an important regulator of the transfer of these signals through differential expression of key placental genes. We used microarrays to examine placental gene expression responses to maternal protein deficiency (6% vs. 24% protein) and Heligmosomoides bakeri infection.

Expression of growth-related genes in the mouse placenta is influenced by interactions between intestinal nematode (Heligmosomoides bakeri) infection and dietary protein deficiency.

Description
Biomarkers of osteoarthritis (OA) that can accurately diagnose the disease at the earliest stage would significantly support efforts to develop treatments for prevention and early intervention. The different stages of disease progression are described by the complex pattern of transcriptional regulations. The dynamics in pattern alterations were monitored in each individual animal during the time-course of OA progression.

Description
The goal of the project was to isolate single miRNA-expressing cells labelled by GFP reporter genes under the control of endogenous miRNA promoters and analyze expression levels of miRNA target genes in these cells. GFP-positive miRNA-expressing cells and GFP-negative cells from the rest of the embryos were purified at the same developmental stage to the cellular resolution using fluorescent activated cell sorting (FACS). Focus was on regulation by miR-206 and miR-133 in the developing somites and miR-124 in the developing central nervous system. Comparison of wild-type embryos and those lacking miRNAs revealed predicted

Description
Small RNA deep sequencing analysis was conducted on primary human fibroblasts infected with human cytomegalovirus (HCMV). HCMV-encoded miRNAs accumulated to ~20% of the total smRNA population at late stages of infection, and our analysis led to improvements in viral miRNA annotations and identification of novel HCMV miRNAs. Through crosslinking and immunoprecipitation of Argonaute-bound RNAs from infected cells, followed by high-throughput sequencing (Ago CLIP-seq), we obtained direct evidence for incorporation of all HCMV miRNAs into the endogenous host silencing machinery. Additionally, significant upregulation was observed during infection for a host miRNA cluster containing miR-96, miR-182 and miR-183. We also identified novel non-miRNA forms of virus-derived smRNAs, revealing greater complexity within the smRNA population during HCMV infection. Overall design: High-throughput profiling of smRNAs, Ago1-, and Ago2-associated miRNAs from HCMV-infected fibroblast cells. Wild-type HCMV Towne (Genbank FJ616285.1) was used for these studies.

Description
Histone H3.3 is a highly conserved histone H3 replacement variant in metazoans, and has been implicated in many important biological processes including cell differentiation and reprogramming. Germline and somatic mutations in H3.3 genomic incorporation pathway components, or in H3.3 encoding genes, have been associated with human congenital diseases and cancers, respectively. However, the role of H3.3 in mammalian development remains unclear. To address this question, we generated H3.3 null mouse models through classical genetic approaches. We found H3.3 plays an essential role in mouse development. Complete depletion of H3.3 leads to developmental retardation and early embryonic lethality. At the cellular level, H3.3 loss triggers cell cycle suppression and cell death. Surprisingly, H3.3 depletion does not dramatically disrupt gene regulation in the developing embryo. Instead, H3.3 depletion causes dysfunction of heterochromatin structures at telomeres, centromeres and pericentromeric regions of chromosomes leading to mitotic defects. The resulting karyotypical abnormalities and DNA damage lead to p53 pathway activation. In summary, our results reveal that an important function of H3.3 is to support chromosomal heterochromatic structures, thus maintaining genome integrity during mammalian development. Overall design: RNA-seq in embryos at E10.5 comparing 3 samples with the following genotype Trp53-/-; H3f3afl/-; H3f3bfl/-; Sox2-CreTg/0 to three samples with the following genotype Trp53-/-; H3f3afl/+; H3f3bfl/+; Sox2-CreTg/0

Description
Of the thousands of long non-coding RNAs expressed in embryonic stem (ES) cells, few have known roles and fewer have been functionally implicated in the regulation of self-renewal and pluripotency or reprogramming somatic cells to the pluripotent state. In ES cells, Cyrano is a stably expressed long intergenic non-coding RNA with no previously assigned role. We demonstrate that Cyrano contributes to ES cell maintenance, as its depletion results in loss of hallmarks of self-renewal. Delineation of Cyrano''s network through transcriptomics revealed widespread effects on signaling pathways and gene expression networks that contribute to ES cell maintenance. Cyrano shares unique sequence complementarity with the differentiation-associated microRNA, mir-7, and mir-7 overexpression reduces expression of a key self-renewal factor to a similar extent as Cyrano knockdown. This suggests that Cyrano functions to restrain the action of mir-7. Altogether, we provide a view into the multifaceted function of Cyrano in ES cell maintenance. Overall design: RNA-seq on mouse R1 embryonic stem (ES) cells with two biological replicates transfected with an shRNA knockdown of Cyrano and two biological replicates transfected with a non-targeting control vector.
