View SamplesThe placenta is an understudied organ that has a critical role in mammalian development. In early placental development, the essential process of trophoblast invasion establishes adequate blood flow between mother and fetus. Despite its importance, little is known about the genomic regions responsible for regulating trophoblast invasion. In order to identify enhancers that are important for regulating the process, we carried out ChIP-Seq for an enhancer-associated mark at two time points during early placental development. Combining these data with RNA-Seq data and protein interaction data allowed us to construct a gene-enhancer network describing trophoblast invasion. Overall design: RNA-Seq at two time points in early placenta development (e7.5 an e9.5). There are 3 biological replicates per time point. Samples were pooled and sequenced on two lanes.
Changes in the enhancer landscape during early placental development uncover a trophoblast invasion gene-enhancer network.

View SamplesAbstract: The Drosophila trachea is a branched tubular epithelia that transports oxygen and other gases. trachealess (trh), which encodes a bHLH-PAS transcription factor, is among the first genes to be expressed in the cells that will form the trachea. In the absence of trh, tracheal cells fail to invaginate to form tubes and remain on the embryo surface. Expression of many tracheal-specific genes depends on trh, but all of the known targets have relatively minor phenotypes compared to loss of trh, suggesting that there are additional targets. To identify uncharacterized transcriptional targets of Trh and to further understand the role of Trh in embryonic tracheal formation, we performed an in situ hybridization screen using a library of ~100 tracheal-expressed genes identified by the Berkeley Drosophila Genome Project (BDGP). Surprisingly, expression of every tracheal gene we tested was dependent on Trh, suggesting a major role for Trh in activation and maintenance of tracheal gene expression. A re-examination of the interdependence of the known early-expressed transcription factors, including trh, ventral veinless (vvl) and knirps/knirps-related (kni/knrl), suggests a new model for how gene expression is controlled in the trachea, with trh regulating expression of vvl and kni, but not vice versa. A pilot screen for the targets of Vvl and Kni/Knrl revealed that Vvl and Kni have only minor roles compared to Trh. Finally, genome-wide microarray experiments identified additional Trh targets and revealed that a of biological processes are affected by the loss of trh.
Trachealess (Trh) regulates all tracheal genes during Drosophila embryogenesis.

View SamplesmRNA expression profiles for 3 breast cancer cell lines seeded at different density and grown for different duration Overall design: This experiment is part of a study fo the effect of cell density on drug sensitivity [1]. Cells plated at different densities in 384-well plates were harvested at the indicated times and RNA was extracted using the RNeasy mini kit (Qiagen). To ensure sufficient RNA amounts wells with low cell numbers were pooled. Some conditions have been tested in biollogical replicates grown at the same time. Libraries were prepared by the Broad Technology Labs (BTL) following the protocol for SCRB-Seq described in [2]. Transcripts were quantified by the BTL computational pipeline using Cuffquant version 2.2.1 [3].

View SamplesIn the present study, to identify potential paracrine factor for the stromal regulation of E2-induced epithelial cell proliferation, we treated epithelial and stromal cell populations of mouse uterine primary co-culture with either oil or E2. Three independent RNA pools prepared for each population were then subjected to the Affymetrix gene chip analysis for the whole mouse genome transcripts. Our data revealed up-regulation of 119 genes and down-regulation of 28 genes in epithelial cell populations and up-regulation of 144 genes and down-regulation of 192 genes in stromal cell population.

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.
