Gene profiling: U87 IRE1 dominant negative cells vs. U87ctrl cells in culture

Project description:Transcriptome analysis was performed from human U87 glioblastoma cell clones: U87 IRE1.NCK DN (U87dn, IRE1 dominant negative) and U87 control (U87ctrl, empty plasmid). Cells were grown in DMEM supplemented with 10% FBS and glutamine for 16 hours in culture prior mRNA isolation and analyses U87dn cells expressing a dominant negative transgene of IRE1alpha were compared to U87ctrl cells transfected with the corresponding empty plamid to identify genes associated to tumor invasion and angiogenesis.

IRE1-dependent transcriptome remodelling upon ER stress in human glioma cells

Project description:We investigate the contribution of IRE1 signaling to the modulation of U87 glioma cells transcriptome upon various stresses. To this end, IRE1 control and IRE1 dominant negative expressing U87 glioma cells were subjected to environmental or chemical challenges and their transcriptome monitored using Affymetrix microarrays.

Microarray analysis of glioma cell lines : Temozolomide Sensitive vs. Resistant

Project description:Transcriptional profiling of glioma cells comparing control U87(Temozolomide sensitive) cells with U87R(Temozolomide resistant). The U87 cell line was given a low dose of temozolomide in culture media for 3 weeks, resulting in the formation of temozolomide-resistant cells made as U87R.

Transcription profiling array of human glioblastoma cell line U87 comparing control cells with U87-shLIN7a knockdown cells and rescue cells which have the same Lin7a knockdown but re-express Lin7a lentivirally (U87-shLin7a+Lin7A)

Project description:After performing an in-vivo screening with U87 glioblastoma cells transduced with a knockdown library several genes could be identified. Lin7a which was one of the candidates was further evaluated. Single knockdown of Lin7a in U87 conferred a pro-invasive phenotype in-vitro and in-vivo. Overexpression of Lin7a in the Primary glioblastoma cell line T269 reduced its invasive phenotype. To decipher the underlying pathways U87 control, U87-shLIN7a and U87-shLin7a+Lin7A (rescue cells after re-expression of Lin7A) were analyzed after in-vitro culture by a transcription profiling Array.

Identification of PDGF-dependent patterns of gene expression in U87 glioblastoma cells

Project description:Overall study: Identification of PDGF-dependent patterns of gene expression in U87 glioblastoma cells. RNA was obtained from triplicate dishes of 5 different groups of U87 cells, each (total 15) analyzed with one U95 microarray chip. Three different comparisons were made: 1) Clone 3.1 (34580-34582) vs. clone 3.3 (34583-34585) vs. parent U87 (34592-34594). Purpose: demonstrate that the gene expression profiles between these 3 cell lines are not different, so they could be pooled as a single untreated group. 2) Pooled control group (34580-34585, 34592-34594) vs. clone 8.1 (34586-34588). Purpose: identify genes specifically controlled by autocrine PDGF activity. 3) Clone 8.1 (34586-34588) vs. clone 8.1 treated with PDGF (34589-34591) Purpose: Identify genes specifically induced by exogenous PDGF. Keywords = platelet-derived growth factor Keywords = glioblastoma Keywords = brain cancer Keywords = sterol regulatory element binding protein Keywords = SREBP Keywords: ordered
