Description
It is important to understand how, if at all, antiretroviral prophylaxis with tenofovir disoproxil fumarate (TDF) alone or TDF in conjunction with emtricitabine (FTC) affects gene expression. To ask this question, we used vaginal biopsies from women enrolled in the Genital Mucosal Substudy (GMS) [1] of the Partners PrEP Study (NCT02621242) [2]. Partners PrEP was a randomized Phase III trial of oral TDF or TDF/FTC compared to placebo, which showed that either active drug was effective at protecting against HIV-1 infection. Samples were taken after 24-36 months of oral treatment with placebo, TDF, or TDF/FTC or two months after discontinuation. Treatment adherence was based on plasma TDF concentrations.

Description
It is important to understand how, if at all, antiretroviral prophylaxis with tenofovir disoproxil fumarate (TDF) alone or TDF in conjunction with emtricitabine (FTC) affects gene expression. To ask this question, we used peripheral blood mononuclear cells from women enrolled in the Genital Mucosal Substudy (GMS) [1] of the Partners PrEP Study (NCT02621242) [2]. Partners PrEP was a randomized Phase III trial of oral TDF or TDF/FTC compared to placebo, which showed that either active drug was effective at protecting against HIV-1 infection.

Description
It is important to understand how, if at all, antiretroviral prophylaxis with tenofovir disoproxil fumarate (TDF) alone or TDF in conjunction with emtricitabine (FTC) affects gene expression. To ask this question, we used cervicovaginal biopsies from women enrolled in the Genital Mucosal Substudy (GMS) [1] of the Partners PrEP Study (NCT02621242) [2]. Partners PrEP was a randomized Phase III trial of oral TDF or TDF/FTC compared to placebo, which showed that either active drug was effective at protecting against HIV-1 infection. Samples were taken after 24-36 months of oral treatment with placebo, TDF, or TDF/FTC or two months after discontinuation. Treatment adherence was based on plasma TDF concentrations. The samples in this series are thought to be endocervical biopsies on the basis of their gene expression.

Description
Glioblastomas show heterogeneous histological features. These distinct phenotypic states are thought to be associated with the presence of glioma stem cells (GSCs), which are highly tumorigenic and self-renewing sub-population of tumor cells that have different functional characteristics. To investigate gene expression including lncRNA (long non-coding RNA) in GSC, we have performed high-throughput RNA-sequencing (RNA-seq) experiment using Illumina GAIIx. Overall design: Profiles of gene expression including lncRNA in GSC were generated by RNA-seq using Illumina GAIIx.

Description
We found that a H3K4 specific histone methyltransferase MLL1, a mammalian homologue of Drosophila trithorax, is essential for circadian transcription. MLL1 is in a complex with CLOCK:BMAL1 and contributes to their rhythmic recruitment to circadian promoters and cyclic H3K4 tri-metylation. To analyze the function of MLL1 on circadian gene regulation, we performed comparative microarray analysis of global gene expression levels in WT and MLL1-deficient MEF, at two different circadian time points (CT18 and CT30). This analysis identified several genes whose expression levels were remarkably changed between CT18 and CT30 in WT and MLL1-KO MEF. Typical clock-regulated genes such as Per2, Per3, Bmal1, or Dbp were found to be changing in WT but not in MLL1-KO MEFs.

Description
Oligodendrocytes (OLs) and myelin are critical for normal brain function and they have been implicated in neurodegeneration. Human neuroimaging studies have demonstrated that alterations in axons and myelin occur early in Alzheimer's Disease (AD) course. However, the molecular mechanism underlying the role of OLs in AD remains largely unknown. In this study, we systematically interrogated OL-enriched gene networks constructed from large-scale genomic, transcriptomic, and proteomic data in human AD postmortem brain samples. These robust OL networks were highly enriched for genes associated with AD risk variants, including BIN1. We corroborated the structure of the AD OL coexpression and gene-gene interaction networks through ablation of genes identified as key drivers of the networks, including UGT8, CNP, MYRF, PLP1, NPC1, and NDGR1. Perturbations of these key drivers not only caused dysregulation in their associated network neighborhoods, but also mimicked pathways of gene expression dysregulation seen in human AD postmortem brain samples. In particular, the OL subnetwork controlled by the AD risk gene PSEN1 was strongly dysregulated in AD, suggesting a potential role of PSEN1 in disrupting the myelination pathway towards the onset of AD. In summary, this study built and systematically validated the first comprehensive molecular blueprint of OL dysregulation in AD, and identified key OL- and myelination-related genes and networks as potential candidate targets for the future development of AD therapies. Overall design: The mouse knockout models have been previously described for each of Ugt8 (Coetzee et al., 1996), Cnp (Lappe-Siefke et al., 2003), and Plp1 (Klugmann et al., 1997). For each of the two conditions studied (control and homozygous knockout mice), five mice of either sex were sacrificed at postnatal day 20 and brains were flashed-frozen until analysis. The frontal cortex (FC) and cerebellum (CBM) were dissected out and individually processed. RNA was isolated using Trizol reagent and processed using Ribo-Zero rRNA removal. RNA-sequencing was performed using the Illumina HiSeq2000 with 100 nucleotide paired-end reads. RNA-sequencing reads were mapped to the mouse genome (mm10, UCSC assembly) using Bowtie (version 2.2.3.0), TopHat (version 2.0.11), and SamTools (version 0.1.19.0) using a read length of 100. Reads were converted to counts at the gene level using HTSeq on the BAM files from TopHat2 using the UCSC known genes data set.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Partial induced pluripotent cells (iPSCs) are cell lines strayed from normal route from somatic cells to iPSCs and are immortalized. Mouse partial iPSCs are able to convert to real iPSCs by the exposure to 2i condition using MAPK and GSK3? inhibitors. However, the molecular mechanisms of this conversion are totally not known. Our piggyback vector mediated genome-wide screen revealed that Cnot2, one of core components of Ccr4-Not complex participates in this conversion. Subsequent analyses revealed other core components, i.e., Cnot1 and Cnot3 and Trim28 which is known to extensively share genomic binding sites with Cnot3 contribute to this conversion as well. Our bioinformatics analyses indicate that the major role of these factors in the conversion is the down-regulation of developmental genes in partial iPSCs.

Description
In this study, we used a cross-species network approach to uncover nitrogen (N)-regulated network modules conserved across a model and a crop species. By translating gene network knowledge from the data-rich model Arabidopsis (Arabidopsis thaliana, ecotype Columbia-0) to a crop, rice (Oryza sativa spp. japonica (Nipponbare)), we identified evolutionarily conserved N-regulatory modules as targets for translational studies to improve N use efficiency in transgenic plants.
