Distinct mechanisms of transcriptional pausing orchestrated by GAGA factor and M1BP, a novel transcription factor.

Li Jian J Gilmour David S DS

The EMBO journal 20130524 13

Thousands of genes in Drosophila have Pol II paused in the promoter proximal region. Almost half of these genes are associated with either GAGA factor (GAF) or a newly discovered factor we call M1BP. Although both factors dictate the association of Pol II at their target promoters, they are nearly mutually exclusive on the genome and mediate different mechanisms of regulation. High-resolution mapping of Pol II using permanganate-ChIP-seq indicates that pausing on M1BP genes is transient and coul ...[more]

Gene expression profiling during diapause induction in Culex pipiens mosquitoes

Project description:Investigation of gene expression level differences in Culex pipiens (SB) and C. quinquefasciatus (JHB) at three time points (8, 16, and 24 hours post-exposure) during the early pupal state in standard (25Â°C; 16 h light/8 h dark) and diapause-inducing (18Â°C; 8 h light/16 h dark) conditions. A forty-eight chip study (4 Expr12x135K slides) using cDNA from total RNA collected from two species in the Culex pipiens complex at 3 time-points during the early pupal stage to study gene expression differences between standard (25Â°C; 16 h light/8 h dark) and diapause-inducing (18Â°C; 8 h light/16 h dark) conditions, and between Culex pipiens (diapause) and C. quinquefasciatus (no diapause). Each chip measures the expression level of 18,692 protein coding genes, with 3 probes per gene and two-fold technical redundancy. Each of the 12-plex slides was used for one of four biological replicates. Probes were designed using the C.quinquefasciatus CpipJ1.2 geneset in VectorBase.

Changes in gene expression in BAZ1B knockout and heterozygous targeted clones

Project description:Williams syndrome transcription factor (WSTF) is a multifaceted protein that is involved in several nuclear processes, including replication, transcription, and the DNA damage response. WSTF participates in a chromatin-remodeling complex with the ISWI ATPase, SNF2H, and is thought to contribute to the maintenance of heterochromatin, including at the human inactive X chromosome (Xi). WSTF is encoded by BAZ1B, and is one of twenty-eight genes that are hemizygously deleted in the genetic disorder Williams-Beuren syndrome (WBS). To explore the function of WSTF, we performed zinc finger nuclease-assisted targeting of the BAZ1B gene and isolated several independent knockout clones in human cells. Our results show that, while heterochromatin at the Xi is unaltered, new inappropriate areas of heterochromatin spontaneously form and resolve throughout the nucleus. In three independent mutants, the expression of a large number of genes were impacted, both up and down, by WSTF loss. In addition, we found that cells lacking WSTF responded appropriately to vitamin D treatment, a process we expected to be disrupted. Given the inappropriate appearance of regions of heterochromatin in BAZ1B knockout cells, it is evident that WSTF performs a critical role in maintaining chromatin and transcriptional states. Clearly, further exploration is necessary to fully understand the role of WSTF in maintenance of the epigenome and how WSTF haploinsufficiency contributes to the wide array of symptoms exhibited in WBS patients. Samples include three replicate miroarray hybridizations of the parental cells (hTERT-RPE1), three replicates from three independent knock-out clones (D5, F3 and M1), and one set of replicates for a heterozygous mutant clone (A6).

Expression analysis of Shewanellla oneidensis MR-1 to Fe nanoparticle decorated anodes in microbial electrolysis cells

Project description:Investigation of whole genome gene expression level changes in a Shewanella oneidensis MR-1 to Fe nanoparticle decorated anodes, compared to the carbon plate anodes in microbial electrolysis cells. Whole genome microarray analysis of the gene expression showed that the encoding biofilm formation genes were significantly up-regulated as response to nanoparticle decorated anodes which indicated thickness improvements contributed to enhance current density. The increased expression genes related to nanowire, flavins and c-type cytochromes also have partially contributed to enhance current density by Fe nanoparticle decorated anode. The majority of additional differentially expressed genes associated with electron transport, anaerobic metabolism in response to the nanostructured anodes possibly play roles in current density enhancement. A six chip study using total RNA recovered from three separate replicates of biofilm on Fe Nanoparticle decorated anode of Shewanella oneidensis MR-1 and three separate replicates of carbon plate control. Each chip measures the expression level of 4,295 genes .

Multipotent mammary cancer stem cells integrate stem cell and clonal expansion theories of tumor progression

Project description:The diversity of human breast cancer subtypes has led to the hypothesis that breast cancer is a number of different diseases arising from cells at various stages of differentiation. We have derived clonal multipotent metastatic mammary cancer stem cells from the polyomavirus middle T mouse model of breast cancer, that can differentiate into luminal, myoepithelial and alveolar cells. When injected orthotopically at low-density, the resulting tumors express estrogen and progesterone receptors. With continued passage in vivo, the tumor cells undergo additional epigenetic and/or genetic changes that result in upregulation of Her2 expression or clonal expansion of cells that give rise to basal-like or claudin-low tumors. As in human tumors, the more aggressive tumor subtypes express nuclear p53. The temporal sequence of events suggests that contrary to current dogma, multiple tumor subtypes can originate from a single multipotent cancer stem cell that undergoes evolution during tumor progression. Furthermore, these data raise the possibility that a human polyomavirus may be a causative agent in spontaneous forms of human breast cancer. Three spontaneous PyVmT tumors and forty cell line derived tumors were analyzed. To generate cell line derived tumors, 10^6 tumor cells were injected orthotopically into four abdominal mammary fat pads in syngeneic C57Bl/6 female mice. After 6-8 weeks the mice were euthanized and the tumors excised and frozen at -80Â°C. One tumor per mouse 8-10mm in diameter was used for array analysis. RNA was extracted using the RNeasy kit (Qiagen) with on column DNA removal.
