Chromatin Immunoprecipitation of TRA-1 in C. elegans and C. briggsae

ABSTRACT: The goal of this study is to identify and characterize sites in the C. elegans genome bound by the transcription factor TRA-1. TRA-1 ChIP-seq was performed in the following stages of animals in duplicate: 1) L2 stage of C. elegans wild-type N2 strain; 2) L3 stage of C. elegans wild-type N2 strain; 3) young adult stage of C. elegans glp-4(bn2) mutant; 4) young adult stage of C. elegans spe-11(hc77) mutant; 5) L3 stage of C. briggsae wild-type AF16 strain. As a negative control, TRA-1 ChIP-seq was also performed in C. elegans L3 stage with tra-1(e1834) homozygous and heterozygous mutation. Input DNA was also sequenced in each condition.

TRA-1 ChIP-seq reveals regulators of sexual differentiation and multilevel feedback in nematode sex determination.

How sexual regulators translate global sexual fate into appropriate local sexual differentiation events is perhaps the least understood aspect of sexual development. Here we have used ChIP followed by deep sequencing (ChIP-seq) to identify direct targets of the nematode global sexual regulator Transformer 1 (TRA-1), a transcription factor acting at the interface between organism-wide and cell-specific sexual regulation to control all sex-specific somatic differentiation events. We identified 184 ...[more]

Microarray analysis of genes associated with cell surface NIS protein levels in breast cancer

Project description:Na+/I- symporter (NIS)-mediated iodide uptake allows radioiodine therapy for thyroid cancer. NIS is also expressed in breast tumors, raising potential for radionuclide therapy of breast cancer. However, NIS expression in most breast cancers is low and may not be sufficient for radionuclide therapy. A better understanding of the mechanisms of NIS regulation in breast cancer may lead to strategies for increasing cell surface NIS and radioactive iodide uptake (RAIU) in breast cancer. The MCF-7 cell line is the only human breast cancer cell line with inducible endogenous NIS expression. Kogai et al. [2000] first reported that trans-retinoic acid (tRA) induces NIS mRNA expression in MCF-7 cells and it was later reported that a combination treatment of tRA and hydrocortisone (tRA/H) further increases tRA-induced NIS expression/function in MCF-7 cells (Kogai et al., 2005; Dohan et al., 2006). In this study, we used gene expression profiling to identify genes that correlate with NIS expression in MCF-7 cells such that mechanisms underlying NIS modulation may be elucidated. MCF-7 cells were treated with DMSO vehicle, tRA (1µM), or tRA(1µM)/H(1µM) for 12 hours and total RNA was extracted. There are two replicates for each treatment group.

Gene expression induced in HEK293 by treatment with the differentiating agents all-trans retinoic acid (tRA) and N6,2'-O-dibutyryl-cAMP (cAMP)

Project description:This gene array analysis shows that the transcriptome of HEK293, representing low-differentiated human embryonic kidney cells, cultured in presence of tRA and cAMP differentiating agents, is consistent with a genetic program relevant to kidney development Comparison of HEK293 cells grown in standard contitions or in presence of differentiating agents. Cells were seeded in 10 cm dishes, cultured for 3 days either in complete medium or in medium supplemented with tRA and cAMP, harvested, and spun down before RNA isolation. Comparative analysis allowed us to identify genes transcriptionally by tRA/cAMP.

Comparison of gene expression at day 11 of iPSC reprogramming with different reprogramming cocktails

Project description:To identify genes altered upon LIN-41 expression during reprogramming to induced pluripotent stem cells, human dermal fibroblasts were infected with combinations of GFP alone, OSK, OSKM, OSK+LIN-41, or OSK+let-7 inhibitor (transfected on days 1 and 6). After 11 days, TRA-1-60+ reprogramming cells were isolated as described in Tanabe et al 2013 or in the case of GFP-infected fibroblasts, GFP+ cells were collected. Total RNA was used for gene expression analysis. After 11 days of reprogramming with OSK, OSK+let-7inh, OSKM, or OSK+LIN-41, TRA-1-60+ cells were isolated and total RNA was isolated.

seq-WA30534819_H3K4me3_N2_MXemb

Project description:modENCODE_submission_3169 We analyzed H3 lysine 4 trimethylation levels in the C. elegans genome using chromatin immunoprecipitation followed by Illumina sequencing. We used wild type (N2) mixed developmental stage embryos and performed the experiment in two biological replicates. This series consists of two biological replicates of H3K4me3 ChIP-seq experiments and their input sequences.

AP-MS of MAGU-2 in the nematode C. elegans

Project description:The Crumbs complex is a regulator of epithelial polarity and is important for the formation of the apical domain. The Crumbs complex consists of the Crumbs protein, Pals1, and PATJ. In C. elegans, we identify MAGU-2 as an ortholog of Pals1. We find that MAGU-2 localizes apically in epithelial cells and its localization is dependent on Crumbs. AP-MS was performed on animals endogenously expressing MAGU-2::GFP and four control strains to identify interactors of MAGU-2. From the data, we identify MPZ-1 as the top hit and identify it as the C. elegans ortholog of PATJ.

RNA-Seq of cKIT+ sorted cells from 53-137 day old fetal testes and ovaries and RNA-Seq of TRA-1-81+ H1 and UCLA1 hESCs.

Project description:We performed RNA-Seq analyses on 15 human fetal samples at 53-137 days of development, 9 female and 5 male, and identified the transcriptional changes during the transition of human cKIT+ primordial germ cells (PGCs), the precursors of gametes, to the generation of Advanced Germline Cells. Comparing the transcriptional profile of PGCs to that of H1 and UCLA1 hESCs identifies differences between the two cell types and pinpoints molecules that can be used in the development of in vitro germ cell differentiation protocols starting from human pluripotent stem cells. RNA-Seq of cKIT+ cells analyzed from 6 biological samples for testes and 9 samples for ovaries from 53-137 days. 2 biological replicates of TRA-1-81+ cells sorted from H1 and UCLA1 hESCs. WGBS of cKIT+ cells analyzed from 4 biological samples of ovaries and 1 biological sample of testes at 57-137 days of development.
