Gene expression microarray analysis of lncRNA TCAM1P-004-knockdown or RP11-598D14.1-knockdown in MIHA cells

ABSTRACT: Downregulations of TCAM1P-004 and RP11-598D14.1 were frequently observed in HCC tumors as compared to adjacent non-tumor tissues. To further study the molecular functions of TCAM1P-004 and RP11-598D14.1, we attempted to identify the gene targets regulated by either lncRNAs. Knockdown of TCAM1P-004 or RP11-598D14.1 were achieved by transduction of lentivirus carrying respective shRNAs in non-tumor hepatocyte MIHA cells. Diffferentially expressed genes after knockdown of the lncRNAs were compared to cells tranduced with lentivirus carrying scramble shRNAs.

A novel small-molecule inhibitor of STAT5A/STAT5B with therapeutic potential for prostate cancer and CML

Project description:We assessed the gene expression profiles induced by both genetic and pharmacological knockdown of Stat5a/b in CML cells. Stat5 was suppressed in K562 cells by lentiviral expression of Stat5 shRNA vs. scramble control for 6 days or by treatment of the cells with IST5-002 (5 µM) for 48 h. K562 cells were treated with IST5-002 (5 µM) or vehicle (DMSO) for 48 h. For Stat5 knockdown, K562 cells were infected with Stat5-shRNA lentivirus or scramble-shRNA lentivirus (as control) for 48 h followed by puromycin (2ug/ml) selection for 6 days to enrich for cells expressing Stat5 or scramble shRNA. Each group (vehicle control, IST5-002, scramble-shRNA control and Stat5-shRNA) was prepared in triplicate, and RNA samples from each group were not pooled.

Gene expression profile of gastric cancer stem cells after CD44 knockdown

Project description:We did the microarray to further compare the changes of gene expression between gastric cancer stem cells with CD44 knockdown by lentivirus and gastric cancer stem cells by scamble short hairpin RNA. Gastric cancer stem cells (Lentivirus) were infected with lentivirus that expressed human CD44-speciï¬c short hairpin RNA (shRNA). Control group of gastric cancer stem cells (Vector group) were only infected with scramble shRNA.

Transcription profiling of human Ewing sarcoma samples and EWS-FLI-1 inhibited Ewing sarcoma cell lines

Project description:The cellular origin of Ewing tumor (ET), a tumor of bone or soft tissues characterized by specific fusions between EWS and ETS genes, is highly debated. Through gene expression analysis comparing ETs with a variety of normal tissues, we show that the profiles of different EWS-FLI1-silenced Ewing cell lines converge toward that of mesenchymal stem cells (MSC). Moreover, upon EWS-FLI1 silencing, two different Ewing cell lines can differentiate along the adipogenic lineage when incubated in appropriate differentiation cocktails. In addition, Ewing cells can also differentiate along the osteogenic lineage upon long-term inhibition of EWS-FLI1. These in silico and experimental data strongly suggest that the inhibition of EWS-FLI1 may allow Ewing cells to recover the phenotype of their MSC progenitor. Experiment Overall Design: Ewing tumors and EWS-FLI-1 inhibited cell lines were profiled on Affymetrix U133A (GPL96) arrays.

Effect of PRR15 knockdown on human trophoblast cell gene expression

Project description:Proline rich 15 (PRR15) is a small nuclear protein required for normal conceptus development in the sheep. We used microarrays to assess the changes in the trophoblast transcriptome when PRR15 expression was diminished. The human first-trimester trophoblast cell line, ACH-3P, was infected with control lentivirus expressing no shRNA or lentivirus expressing shRNA to target PRR15 mRNA for degradation, with three biological replicates per treatment.

A Long Non-coding RNA, LncMyoD, Regulates Skeletal Muscle Differentiation by Blocking IMP2-mediated mRNA Translation

Project description:Increasing evidence suggests that Long non-coding RNAs (LncRNAs) represent a new class of regulators of stem cells. However, the roles of LncRNAs in stem cell maintenance and myogenesis remain largely unexamined. For this study, hundreds of novel intergenic LncRNAs were identified that are expressed in myoblasts and regulated during differentiation. One of these LncRNAs, termed LncMyoD, is encoded next to the Myod gene and is directly activated by MyoD during myoblast differentiation. Knockdown of LncMyoD strongly inhibits terminal muscle differentiation largely due to a failure to exit the cell cycle. LncMyoD directly binds to IGF2-mRNA-binding-protein 2 (IMP2) and negatively regulates IMP2-mediated translation of proliferation genes such as N-Ras and c-Myc. While the RNA sequence of LncMyoD is not well-conserved between human and mouse, its locus, gene structure and function is preserved. The MyoD-LncMyoD-IMP2 pathway elucidates a mechanism as to how MyoD blocks proliferation to create a permissive state for differentiation. In order to perform an unbiased search for downstream signaling pathways perturbed by LncMyodD downregulation, microarrays were performed on myoblasts treated with control vs LncMyoD shRNAs. Total RNA was extracted using the TRIzol reagent (Invitrogen) and purified with Qiagen RNeasy separation columns (Qiagen) from myoblasts treated with control vs. LncMyoD shRNA. First-strand cDNA was synthesized and hybridized to GeneChip Mouse Genome 430 2.0 Array (Affymetrix).

Effect of OVO-like 1 knockdown on global transcript expression in differentiated BeWo trophoblast cells

Project description:We had previously discovered that the transcription factor OVO-like 1 (OVOL1) was highly induced during trophoblast differentiation. In this study, we used an lentiviral shRNA strategy to decrease OVOL1 expression in BeWo trophoblast cells. Control cells were transduced with shRNAs targeting no known mammalian transcript (shCont). Following stimulation of differentiation (48h exposure to 8-bromo-cyclic adenosine monophosphate), a RNA-seq approach was used to determine global transcript differences in OVOL1-knockdown cells compared to control cells. Trophoblast cells transduced with control shRNAs were used as controls. Cells transduced with shRNAs targeting OVOL1 were used as treatment. All cells received 250 uM 8-bromo-cyclic adenosine monophosphate to stimulate differentiation. Three independent replicates of control and treatment groups were analyzed.
