RNA-seq of the human breast cancer ERÎ±-suppressed MCF-7(MCF-7/SP10+) cells and of their internal control MCF-7 (MCF-7/C) cells

ABSTRACT: Estrogens receptor a (ERÎ±) is essential for breast tumors,since about seventy percent of breast cancers are detected as ERÎ± positive.Recent studies suggest that ERÎ± is related with the epithelial cell morphology. Recently, it has demonstrated that the suppression of ERÎ± induced epithelial-mesenchymal transition (EMT) in the MCF-7 breast cacner cells. Interestingly, the loss of ERa resulted in strong differences on the gene expression profile of a variety of genes. Therefore, the aim of the RNA-seq is to elucidate the effect of the silencing of ERÎ± on the mRNA levels of a larger variety of genes, thus revealing possible target genes which may be implicated on the aggressive phenotype and behavior of the ERÎ±-suppresed MCF-7/SP10+ breast cancer cells. For this reason total RNA from both MCF-7/SP10+ cells and of their internal control MCF-7/C cells was extracted in 3 biological replicates and 3 technical replicates.

Innate lymphoid cell development requires TOX-dependent generation of a common ILC progenitor

Project description:Subtypes of innate lymphoid cells (ILC), defined by effector function and transcription factor expression, have recently been identified. In the adult, ILC derive from common lymphoid progenitors in bone marrow, although transcriptional regulation of the developmental pathways involved remains poorly defined. TOX is required for development of lymphoid tissue inducer cells, a type of ILC3 required for lymph node organogenesis, and NK cells, a type of ILC1. We show here that production of multiple ILC lineages requires TOX, as a result of TOX-dependent development of common ILC progenitors. Comparative transcriptome analysis demonstrated failure to induce various aspects of the ILC gene program in the absence of TOX, implicating this nuclear factor as a key early determinant of ILC lineage specification.

Prox1 (Prosper-related homeobox 1) transcription factor depletion effect on CGTH-W-1 cells.

Project description:Analysis of CGTH-W-1 follicular thyroid carcinoma cells transcriptome following 48 hrs siRNA-mediated depletion of PROX1. PROX1 is a homeobox transcription factor. PROX1 depletion decreases migratory ability, motility and invasivness and induces profound cytoskeleton changes of CGTH-W-1 cells. Results provide insight into the role of PROX1 in the thyroid cancer. Three biological replicates for a given condition

RNA-sequencing of human umbilical cord-derived MSC (UCX) in normoxia and hypoxia

Project description:Human umbilical cord matrix-derived mesenchymal stromal cells (UCM-MSC) are advantageous since can be easily obtained and display special interest as universal and feasible add-on therapy for myocardial infarction (MI). In this study, UCM-MSC from two umbilical cords, UC-A and UC-B, were transplanted in a murine MI model to investigate consistency and durability of the therapeutic benefits. Both cellular products supported sustained and long-term beneficial therapeutic effect. In vitro, the two cell products displayed similar ability to induce the formation of vessel-like structures and comparable transcriptome in normoxia and hypoxia, apart from expression differences in a small subset of genes associated with MHC Class I. These findings support that UCM-MSC are strong candidates to assist the treatment of MI whilst calling for the discussion on methodologies to characterize and select best performing UCM-MSC before clinical application.

Transcriptomic analysis by AmpliSeq Ion Torrent to explore the effects of the long non-coding RNA TGFB2-AS1 on gene expression in human keratinocytes

Project description:TGFB2-AS1 is a long non-coding RNA which is induced by ΤGFβ signaling. In order to assess the importance of TGFB2-AS1 on the regulation of gene expression, we performed an AmpliSeq transcriptomic array in human keratinocytes (HaCaT), which stably over-express TGFB2-AS1 or control pcDNA3 empty vector. In addition, cells were stimulated with TGFβ1 for 24 hours, in order to observe the effects of TGFB2-AS1 on gene expression, downstream of TGFβ signaling. RNA from the following four conditions was used in this experiment: 1) pcDNA3, 2) pcDNA3+TGFβ1, 3) pcDNA3-TGFB2-AS1, 4) pcDNA3-TGFB2-AS1+TGFβ1. Biological triplicates were used per condition.

Transcriptome and Micronome analysis of OPLL

Project description:Ossification of the posterior longitudinal ligament (OPLL) is formed by heterogeneous ossification of posterior longitudinal ligament. The patho-mechanism of OPLL is still largely unknown. MicroRNAs are small nucleatides that function as regulators of gene expression in almost any biological process. However, few microRNAs are reported to have a role in the pathological process of OPLL. Therefore, we performed high-throughput microRNA sequencing and transcriptome sequencing of primary OPLL and PLL cells in order to decipher the interacting network of microRNAs in OPLL. MRNA and microRNA profiles were done using primary culture cells of human ossification of the posterior longitudinal ligament (OPLL) tissue and normal posterior longitudinal ligament (PLL) tissue.

Smyd3 is a transcriptional potentiator of multiple cancer-promoting genes and required for liver or colon cancer development

Project description:Smyd3 is a histone methyltransferase implicated in tumorigenesis. Here we show that Smyd3 expression in mice is required but not sufficient for chemically induced liver and colon cancer formation. In these organs Smyd3 is functioning in the nucleus as a direct transcriptional activator of several key genes involved in cell proliferation, epithelial-mesenchymal transition, JAK/Stat3 oncogenic pathways, as well as of the c-myc and b-catenin oncogenes. Smyd3 specifically interacts with H3K4Me3-modified histone tails and is recruited to the core promoter regions of many but not all active genes. Smyd3 binding density on target genes positively correlates with increased RNA Pol-II density and transcriptional outputs. The results suggest that Smyd3 is an essential transcriptional potentiator of a multitude of cancer-related genes. Standard Smyd3-deficient (Smyd3-KO) mice were generated using gene-trap ES cell clones (AS0527 from International Gene Trap Consortium), in which a selection cassette, containing the splice acceptor site from mouse EN2 exon 2 followed by the beta-galactosidase and neomycin resistance gene fusion gene and the SV40 polyadenylation sequence was inserted into the 5th intron of the Smyd3 gene. The resulting mice were devoid of Smyd3 mRNA and protein in all tissues, including liver and colon. For the generation of Smyd3-Tg mice the open reading frame of the mouse Smyd3 cDNA, which contained 3 Flag epitopes at the 3â end was inserted into the StuI site of the pTTR1-ExV3 plasmid (Yan et al, 1990). The 6.8 kb HindIII fragment containing the mouse transthyretin enhancer/promoter, intron 1, Smyd3 cDNA, three Flag epitopes and SV40 poly-A site was used to microinject C57Bl/6 fertilized oocytes. Founder animals were identified by Southern blotting and crossed with F1 mice to generate lines. Specific overexpression in the liver was tested by RT-PCR analysis in different tissues.
