View SamplesThe optic vesicle comprises a pool of bi-potential progenitor cells from which the retinal pigment epithelium (RPE) and neural retina fates segregate during ocular morphogenesis. Several transcription factors and signaling pathways have been shown to be important for RPE maintenance and differentiation, but an understanding of the initial fate specification and determination of this ocular cell type is lacking. We show that Yap/Taz-Tead activity is necessary and sufficient for optic vesicle progenitors to adopt RPE identity in zebrafish. A Teadresponsive transgene is expressed within the domain of the optic cup from which RPE arises, and Yap immunoreactivity localizes to the nuclei of prospective RPE cells. yap (yap1) mutants lack a subset of RPE cells and/or exhibit coloboma. Loss of RPE in yap mutants is exacerbated in combination with taz (wwtr1) mutant alleles such that, when Yap and Taz are both absent, optic vesicle progenitor cells completely lose their ability to form RPE. The mechanism of Yap dependent RPE cell type determination is reliant on both nuclear localization of Yap and interaction with a Tead co-factor. In contrast to loss of Yap and Taz, overexpression of either protein within optic vesicle progenitors leads to ectopic pigmentation in a dosagedependent manner. Overall, this study identifies Yap and Taz as key early regulators of RPE genesis and provides a mechanistic framework for understanding the congenital ocular defects of Sveinsson’s chorioretinal atrophy and congenital retinal coloboma. Overall design: 60 pooled eyes from 36 hpf wild type or vsx2:Gal4/dsRed:14xUAS:YapS87A embryos were pooled for one sample. Three wild type and three vsx2:Gal4/dsRed:14xUAS:YapS87A pools were analyzed for RNA.

View SamplesWe present a new wholly defined Affymetrix spike-in dataset consisting of 18 microarrays. Over 5700 RNAs are spiked in at relative concentrations ranging from 1- to 4-fold, and the arrays from each condition are balanced with respect to both total RNA amount and degree of positive- versus negative-fold change. We use this new Platinum Spike dataset to evaluate microarray analysis routes and contrast the results to those achieved using our earlier Golden Spike dataset.

View SamplesMfng, a modulator of Notch signaling, is highly expressed in human claudin-low breast cancer (CLBC). To determine Mfngs roles in CLBC pathogenesis,we knocked down Mfng in a CLBC cell line MDA-MB231, and found that Mfng knockdown altered Notch activation, decreased tumor sphere formation in vitro, and reduced tumor growth in xenograft model. To identify the potential downstream targets of Mfng during CLBC tumorigenesis, we compared the gene expression profiles between xenografts tumor derived from of MDA-MB231 cells carrying Mfng shRNA and the control vector. Mfng, a modulator of Notch signaling, is highly expressed in human claudin-low breast cancer (CLBC). To determine Mfngs roles in CLBC pathogenesis,we knocked down Mfng in a CLBC cell line MDA-MB231, and found that Mfng knockdown caused alteration in Notch activation, associated with decreased tumor sphere formation in vitro, as well as reduced tumor growth in xenograft model. We intend to compare gene expression profiles between xenografts of MDA-MB231 cells carrying Mfng shRNA and the control vector. This project seeks to identify potential downstream targets of Mfng in CLBC.

View SamplesChlamydia pneumoniae, an obligate intracellular bacterium, causes pneumonia in humans and mice. Toll-like receptors and the key adaptor molecule MyD88 play a critical role in inducing immunity against this microorganism and are crucial to survive the infection. To explore the influence of MyD88 on induction of immune responses in vivo on a genome wide level, WT or MyD88-/- mice were infected with C. pneumoniae upon anesthesia and the pulmonary transcriptome was analyzed three days later by microarrays. We find that the infection induced the transcription of 360 genes and repressed 18 genes in WT mice. Of these, 221 genes were not or weakly induced in lungs of MyD88-/- mice. This cluster contains primarily genes encoding for chemokines, cytokines and other immune effector molecules. Genes induced by interferons were abundant in a cluster of 102 genes which were only partially MyD88-dependent. Interestingly, a set of 37 genes were induced more strongly in MyD88-/- mice and most of them are involved in the regulation of cellular replication. In summary, ex vivo analysis of the pulmonary transcriptome upon infection with C. pneumoniae demonstrated a major impact of MyD88 on inflammatory responses but not on interferon-type responses, and identified MyD88-independent genes involved in cellular replication
