Gene expression data from cultured mouse cortical (mCTX) neurons in different stimulation and knockdown conditions

ABSTRACT: Although the induction of C-FOS in the brain has been extensively studied for several decades to date there has been no attempt to identify the targets of C-FOS at a genome wide level, and it was not known how many genes C-FOS activates in a given cell. To identify potential C-FOS target genes, we performed microarray analysis on RNA obtained from mouse cortical (mCTX) neurons infected with lentivirus containing either a control shRNA (targeting firefly luciferase) or c-Fos shRNA that were subsequently depolarized with 0, 1, 3, or 6 hours of KCl. Embryonic day 16.5 cortices from C57BL/6 mice were dissected, dissociated, plated, and subsequently grown in a cell culture incubator that maintained a temperature of 37 degrees C and a CO2 concentration of 5%. On DIV5, lentiviral supernatant containing either a lentivirus expressing a control shRNA targeting firefly luciferase or a lentivirus expressing shRNA targeting c-Fos was applied to cultures for 6hrs with 6ug/mL polybrene. At DIV7, mCTX neurons were silenced and stimulated with KCl for either 0, 1, 3, or 6hrs, and total RNA was purified using Trizol and the RNeasy mini kit from Qiagen. 10ug of labeled cDNA was subsequently hybridized to Affymetrix mouse genome 430 2.0 arrays with affymetrix processing.

Transcription profiling of mouse naive CD4+CD25-CD62Lhi T cells and nTreg cells with Eos knock-down

Project description:Eos expression in Treg cells have been documented by several microarrays including ours. We hypothesized that Eos facilitates Foxp3- dependent gene repression in Regulatory T cells. In order to investigate the role of Eos in mediating the Foxp3-dependent gene silencing program, we utilized lentiviral shRNA knockdown of Eos in natural Tregs isolated from the periphery of Balb/C mice. A renilla luciferase (RL) gene specific shRNA lentivirus was used as a control for the transduction of cells. The transcriptional profile of naive T cells, natural Tregs, Eos knockdown Tregs, and control shRNA knockdown Tregs was compared using Agilent 4x 44K whole mouse genome array. The goal of this microarray is to document the global effect of the loss of Eos expression on the transcriptional profile of natrual Treg cells. Experiment Overall Design: Eos knock-down (si-Eos) was mediated by Lentivirus expressing GFP as a reporter of transduction and sorting marker. Renilla luciferase specific shRNA lentiviral transduction was carried out in parallel as a control. NaÃ¯ve (CD4+CD25-CD62Lhi) T cells and nTreg cells were freshly isolated from Balb/C mice.

Lentiviral shRNA library screening of tumor growth associated genes in CAPAN2 cells

Project description:Our aim is to identify genes that play important role to cell proliferation in PDAC. Lentivirus shRNA library was transduced to CAPAN2 cells. The cells were orthotopically injected into nude the pancreas of the mice. Tumors were allowed to grow and subsequently total RNA was extracted from the tumor tissues. The differential level of shRNA between tumor cells and uninjected cells were compared.

YAP conveys an invasive phenotype to clear cell renal cell carcinoma cell lines via endothelin-2

Project description:To determine the biological mechanisms underlying the oncogenic properties of YAP in ccRCC the human ccRCC cell line MZ1774 was transduced with lentivirus containing a shRNA-cassette targeting YAP-mRNA. Expression profiles of MZ1774 YAP knockdown cells were compared to mock-transduced control cells. Total RNA from MZ1774 cells stably expressing shRNA directed against YAP compared to mock-transduced MZ1174 cells

PTHR1 knock-down in osteosarcoma cells

Project description:Expression analysis of OS tumors with shRNA knockdown of PTHR1 mouse OS 80 (a Cre:lox OS cell line from Boston) was tagged with firefly luciferase expression construct. They were then infected with either control (renilla luciferase shRNA) or an shRNA that effective knocks-down PTHR1 (PTHR1.358; para-thyroid hormone receptor). The cells were injected with matrigel onto the back flank of Balb/c nu/nu mice and left to grow for 1 month with weekly monitoring of tumour size by in vivo luciferase assay. At 4 weeks the tumours were removed and trizol stored. Whole tumour was ground up and set form micro-array. 6 tumors with shRNA PTHR1 knockdown ; 6 tumors with shRNA control (renilla luciferase shRNA) knockdown

Regulatory RNA Apela Is a Component of a Negative Feedback Loop Regulating p53-Mediated Apoptosis in Embryonic Stem Cells (I)

Project description:p53-repressed transcripts have recently been shown to play important roles in various biological processes, such as stem cell differentiation and cancer. We identified a transcript named Apela that is repressed by p53 and highly expressed in mouse ES cells. To see which transcripts are affected by Apela knockdown, we performed gene expression microarray using Affymetrix Gene ST 1.0 array. Two short hairpin RNAs (shRNAs) targeting Apela were used to decrease the RNA levels of Apela to about 20% of the control (a shRNA target luciferase, shLuc). We designed two lentivirus-based shRNAs against Apela and used shRNA against luciferase as a control. Lentiviruses were made and used to transduced mouse ES cells. For each shRNA, three repeats were done.

Exon Level Expression Profiling: a Novel Unbiased Transcriptome

Project description:Transcriptome analysis of partially degraded and fragmented RNA samples from hiPSCs-derived MNs with Venus or Fos-B + Venus expression by lentivirus infection Fos-B could had a function on axon branching with hiPSCs-derived MNs. However, the grobal profiling under Fos-B expression was not fully elucidated. Thus, we constructed Venus or Fos-B + Venus expression lentivirus and subsequently infected those virus to hiPSCs-derived MNs. Increasing number of axon branching was detected with Fos-B expression MNs, and we demonstrated the pathological confirmation of true exon level expression profiling approach with Fos-B expressed MNs.

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.
