Description
High temporal resolution RNAseq timecourse of mouse ES differentiation Investigations of transcriptional responses during developmental transitions typically use time courses with intervals that are not commensurate with the timescales of known biological processes. Moreover, such experiments typically focus on protein-coding transcripts, ignoring the important impact of long noncoding RNAs. We evaluated coding and noncoding expression dynamics at unprecedented temporal resolution (6-hourly) in differentiating mouse embryonic stem cells and report the effects of increased temporal resolution on the characterization of the underlying molecular processes. Overall design: Biological duplicate 120 hours of undirected mouse ES cell differentiation sampled 6 hourly Biological duplicate, low passage number (P18) W9.5 ESCs were cultured and differentiated as described previously [PMID:18562676; 17286599]. Cultures were harvested every six hours from the induction of differentiation to 120 hours post differentiation induction. Total RNA from cultures was purified using Trizol (Life Technologies) and DNase treatment was performed by RQ1 DNase (Promega) according to the manufacturer’s instructions. RNA integrity was measured on a Bioanalyzer RNA Nano chip (Agilent). RNA-Seq library preparation and sequencing of Poly-A-NGS libraries generated from 500 ng total RNA using SureSelect Strand Specific RNA Library Preparation Kit (Agilent) according to the manufacturer’s instructions. Paired-end libraries were sequenced to the first 100 bp on a HiSeq 2500 (Illumina) on High Output Mode. Library sequencing quality was determined using FastQC (Babraham Bioinformatics) and FastQ Screen (Babraham Bioinformatics). Illumina adaptor sequence and low quality read trimming (read pair removed if < 20 base pairs) was performed using Trim Galore! (Babraham Bioinformatics: www.bioinformatics.babraham.ac.uk/). Tophat2 [PMID:23618408] was used to align reads to the December 2011 release of the mouse reference genome (mm10) as outlined by Anders et al.[PMID:23975260]. Read counts data corresponding to GENCODE vM2 transcript annotations were generated using HTSeq[PMID:25260700]. All analyses were performed in the R Statistical Environment [PMID:18000755]. Briefly, counts data were background corrected and normalized for library size using edgeR [PMID:19910308], then transformed using voom[PMID:24485249] for differential expression analysis using LIMMA[PMID: 16646809].

Description
Macrophages in tumor microenvironment have been characterized as M1- and M2-polarized subtypes. This study sought to investigate the effects of different macrophage subtypes on the biological behavior and global gene expression profiles of lung cancer cells. Expression microarray and bioinformatics analyses indicated that the different macrophage subtypes mainly regulated genes involved in cell cycle, cytoskeletal remodeling, coagulation, cell adhesion and apoptosis pathways in A549 cells, a pattern that correlated with the altered behavior of A549 cells observed after coculture with macrophage subtypes.

Description
The mammary gland at early stages of pregnancy undergoes fast cell proliferation, yet the mechanism to ensure its genome integrity is largely unknown. Here we show that pregnancy enhances expression of genes involved in numerous pathways, including most genes encoding replisomes. In mouse mammary glands, replisome genes are positively regulated by estrogen/ERa signaling but negatively regulated by BRCA1. Upon DNA damage, BRCA1 deficiency markedly enhances DNA replication initiation. BRCA1 deficiency also preferably impairs DNA replication checkpoints mediated by ATR and CHK1 but not by WEE1, which inhibits DNA replication initiation through CDC7-MCM2 pathway and enables BRCA1-deficient cells to avoid further genomic instability. Thus, BRCA1 and WEE1 inhibit DNA replication initiation in a parallel manner to ensure genome stability for mammary gland development during pregnancy.
Publication Title
BRCA1 represses DNA replication initiation through antagonizing estrogen signaling and maintains genome stability in parallel with WEE1-MCM2 signaling during pregnancy.

Description
We report the high-throughput profiling of brain RNA from three Drosophila stains: dBRWD3PX2/+, dBRWD3PX2/PX2 and dBRWD3PX2/PX2, yemGS21861/GS21861. By obtaining over 50 million reads of sequence, WE compared the transcriptomic differences among the brains from these three stains. We found that the expression of 871 genes was significantly different between heterozygous control and homozygous dBRWD3 mutant brains (484 upregulated genes, 387 downregulated genes, p<0.05). Gene ontology (GO) analysis of the 871 genes revealed a broad spectrum of biological processes, ranging from synaptic activity to housekeeping metabolism subjective to dBRWD3 regulation. Among the 387 downregulated genes, the expression of 360 genes (92.8%) was increased in the dBRWD3, yem double mutant brains compared with dBRWD3 mutant. Among the 484 upregulated genes, the expression of 412 genes (85.1%) was decreased in the double mutant brains. These differential genes were evenly distributed on X chromosome and autosomes (149 on X, 178 on 2L, 154 on 2R, 166 on 3L, and 207 on 3R). These analyses indicate that dBRWD3 regulates gene expression in the brain mainly through the HIRA/YEM complex. Overall design: Examination of brain transcriptome in 3 Drosophila strains.

Description
The majority of the human genome is transcribed, yielding a rich repository of non-coding transcripts that are involved in a myriad of biological processes including cancer. However, how non-coding transcripts such as Long Non-coding RNAs (lncRNAs) function in prostate cancer is still unclear. In this study, we have identified a novel set of clinically relevant androgen-regulated lncRNAs in prostate cancer. Among this group, we found LINC00844 is a direct androgen regulated target that is actively transcribed in AR-dependent prostate cancer cells. In clinical analysis, the expression of LINC00844 is higher in normal prostate compared to malignant and metastatic prostate cancer samples and patients with low expression demonstrate poor prognosis and significantly increased biochemical recurrence suggesting LINC00844 may function in suppressing tumor progression and metastasis. From in-vitroloss-of-function studies, we showed LINC00844 prevents prostate cancer cell migration and invasion. Moreover, in gene expression studies we demonstrate LINC00844 functions in trans, affecting global androgen-regulated gene transcription. Mechanistically, we provide evidence to show LINC00844 is important in facilitating AR binding to the chromatin. Finally, we showed LINC00844 mediates its phenotypic effects in part by activating the expression of NDRG1, a crucial cancer metastasis suppressor. Collectively, our findings indicate LINC00844 is a novel coregulator of AR that plays an important role in the androgen transcriptional network and the development and progression of prostate cancer.

Description
Epstein-Barr virus (EBV) Rta is a latent-lytic molecular switch evolutionarily conserved in all gamma-herpesviruses. In previous studies, doxycycline-inducible Rta was shown to potently produce an irreversible G1 arrest followed by cellular senescence in 293 cells. Here, we demonstrate that in this system the inducible Rta not only reactivates resident genome of EBV but also that of Kaposis sarcoma-associated herpesvirus (KSHV), to similar efficiency. However, Rta-induced senescence program was terminated by the robust viral lytic cycle replication that eventually caused cell death. Furthermore, prior to the abrupt expression of immediate-early protein (EBV BZLF1 or KSHV RTA), Rta simultaneously down-regulates cell cycle activators (c-Myc, CDK6, CCND2) and up-regulates senescence-related genes (p21, 14-3-3s). Since Rta is a viral immediate-early transcriptional activator, it is envisioned that during the initial stage of viral reactivation, Rta may engage to modulate the host transcriptome, to halt cell cycle progression, and to maintain an ideal environment for manufacturing infectious virions.
