Description
Analysis of enzalutamide- and/or olaparib-responsive gene expression in prostate cancer cells. The hypothesis tested in the present study was that enzalutamide influences the expression of genes that are involved in important bioprocesses in prostate cance rcells, including DNA damage response genes and this effect may synergize with poly(ADP-ribose) polymerase inhibitor olaparib in cytotoxicity to prstate cancer cells.

Description
Purpose: The goal of this study was to map the pathway of mRNA decay by human RNase L Methods: Total RNA was extracted (RNeasy kit, Qiagen). RNA integrity was verified by an RNA 6000 Nano Chip, using BioAnalyzer and 2100 Expert software (Agilent Technologies). The mRNA was enriched by oligo-dT pulldown from total RNA, followed by fragmentation, adapter ligation, PCR amplification, and finally sequencing on Illumina HiSeq 2000 platform. For sequencing introns, the oligo-dT pulldown step was replaced with Ribo-Zero rRNA removal (Illumina). Sequencing reads were mapped to the human genome hg19 using TopHat 2 set to map stranded reads with default parameters. Mapped read counts were obtained using HTseq-count run in union mode. Results: We developed an approach for transcriptome-wide profiling of RNase L activity in human cells and identified hundreds of direct RNA targets and non-targets. We show that this RNase L-dependent decay (RLDD) selectively affects transcripts regulated by miR-17/miR-29/miR-200 and other microRNAs that function as suppressors of mammalian cell adhesion and proliferation. RNase L mimics the effects of these microRNAs and acts as a suppressor of proliferation and adhesion in mammalian cells. Conclusions: Our data suggest that RLDD serves to establish an anti-proliferative state via destabilization of the microRNA-regulated transcriptome. Overall design: Human mRNA profiles from HeLa, T47D and HAP1 cells were generated by deep sequencing using Illumina Illumina HiSeq 2000.

Description
The germinal center (GC) is a microanatomical compartment wherein high-affinity antibody-producing B cells are selectively expanded. B cells proliferate and mutate their antibody genes in the dark zone (DZ) of the GC and are then selected by T cells in the light zone (LZ) on the basis of affinity. Here, we show that T cell help regulates the speed of cell cycle phase transitions and DNA replication of GC B cells. Genome sequencing and single-molecule analyses revealed that T cell help shortens S phase by regulating replication fork progression while preserving the relative order of replication origin activation. Thus, high-affinity GC B cells are selected by a mechanism that involves prolonged dwell time in the DZ where selected cells undergo accelerated cell cycles. Overall design: To determine whether GC B cells receiving high levels of T cell help show a specific change in gene expression, we compared DZ cells in the G1 phase of the cell cycle from aDEC-OVA and control aDEC-CS treated GCs using a fluorescent ubiquitination-based cell cycle indicator (Fucci-tg). RNA sequencing revealed that T cell-mediated selection produced an increase in gene expression programs associated with the cell cycle, metabolism, including the metabolism of nucleotides, and genes downstream of c-Myc and the E2F transcription factors.

Description
We investigated the molecular mechanisms for osteolytic bone metastasis by selecting human lung cancer cell line subpopulations with elevated metastatic activity and validating genes that are overexpressed in these cells. A bone-seeking squamous lung cancer cell line (HARA-B4) was established by sequentially injecting parental HARA cells into the left ventricle of male 5-week-old nude mice 4 times.
