Transcriptome data from human malanoma A375 cells stably expressing MAP4K5 shRNA

ABSTRACT: MAP4K5 is serine/threonine protein kinase similar to yeast SPS1/STE20 kinase. MAP4K5 activates JNK in mammalian cells, which suggests a role in stress response. MAP4K5 is involved in immune functions. We used microarray to investigate genome-wide transcriptional change from MAP4K5 knockdown in A375 cells. Total RNA's from the A375 cells where MAP4K5 was stably knocked down by shRNA were analyzed. As a control, RNA's from A375 cells were also analyzed.

Genome-wide transcriptome profiling of SK-Mel-28, UACC-62 and HCT-116 cells stably expressing scrambled shRNA and RAB7 shRNA

Project description:"Purpose: Assess the transcriptional changes induced upon RAB7 knock-down in melanoma (SK-Mel-28 and UACC-62) and in colon cancer (HCT-116) cell lines. Methods: mRNA profiles of tumor cell lines (SK-Mel-28, UACC-62, HCT-116) stably expressing scrambled shRNA or RAB7 shRNA (harvested at day 3 after lentiviral infection) were generated by deep sequencing, using three biological replicates per condition. The sequence reads that passed quality filters were analyzed with TopHat and Cufflinks. Validation of induced / silenced genes was performed by western blot. Results show a differential impact of RAB7 expression in the transcriptomic profile of melanoma vs non-melanoma cell lines, and support a lineage-specific role of this small GTPase in melanoma. Examination of the mRNA profiles RAB7-depleted vs wild type cells, performed in parallel in 3 different tumor cell lines (Melanomas: SK-Mel-28 and UACC-62, Non-melanoma: HCT-116) harvested at day 3 after lentiviral infection."

Expression data from catalase stably transfected A375 human melanoma cells

Project description:Reactive oxygen species (ROS) are implicated in tumor transformation by modulating proteins involved in differentiation, proliferation and invasion. In order to identify genes that may support melanoma progression or regression after an antioxidant system (AOS) response, we developed and characterized a human melanoma cell model with different levels of ROS by stably overexpressing the antioxidant enzyme catalase in A375 amelanotic melanoma cells, and whole genome gene expression patterns were analyzed by microarrays. We used gene expression microarrays to study the AOS global response to catalase overexpression and to identify up-regulated and down-regulated genes during progression or regression of melanoma.

Expression data from human breast cancer cell MDA-MB-231 stably expressing MYOSIN10 shRNA versus scramble shRNA

Project description:We used MYOSIN10 shRNA to stably silence the expression of endogenous MYOSIN10 in Breast cancer cell MDA-MB-231. To investigate the inner change of cells with silenced MYOSIN10, we conducted a genome-wide screening for all potential genes affected by MYOSIN10 shRNA using Affymetrix Human Genome U133 plus 2.0 array. We showed genes affected by MYOSIN10 knockdown in breast cancer cell MDA-MB-231

Expression data of NCI-H441 cells stably expressing hsa-mir-365-2 vs empty vector

Project description:Hsa-mir-365-2 is one of the two precursors that give rise to miR-365. We discovered that miR-365 directly regulates a lung cancer and developmental gene termed thyroid transcription factor 1 (TTF-1 or NKX2-1). Hsa-mir-365-2 was transfected into NCI-H441 cells via retrovirus-mediated gene transfer. Arrays hybridized: Affymetrix GeneChip Human Gene 1.0 ST Array. A total of 4 samples were analyzed. The first two were H441 cells expressing hsa-mir-365-2 and the other two were H441 transfected with empty vector. The class comparison function (significant cutoff, 0.001) of BRB Array Tool (4.1.0 beta_3 release) was used to analyze for differentially expressed genes as a result of enforced expression of hsa-mir-365-2.

Project description:We used microarrays to explore the expression profile from cells expressing wild type and UHRF1 S674A mutant. HeLa cells expressing UHRF1 WT and S674A mutant showed similar gene expression pattern without significant affecting the transcription of DNA repari genes.

Expression data from human primary fibroblasts (IMR90) stably expressing H-RasV12 and shRNA against ERK2 or a non-targeting shRNA

Project description:Oncogenic ras activates several signaling pathways that cooperate in cell transformation. They include the ERK/MAP kinase pathway, the PI3K pathway and the Ral pathway among others. Surprisingly, in primary human fibroblasts, oncogenic ras expression induces senescence not transformation, but upon knockdown of ERK2 senescence is bypassed and transformation is stimulated. We used microarrays to characterize the gene expression programme of cells transformed by oncogenic ras, telomerase and knockdown of the ERK2 kinase. Primary human fibroblasts were co-infected with a retroviral vector that expresses oncogenic ras and either a control shRNA or an shRNA against ERK2. Cells with oncogenic ras and shRNA control entered senescence while cells with oncogenic ras and shRNA ERK2 bypassed senescence and underwent malignant transformation. Triplicates of these populations were used to purify total RNA, which we sent to Genome Quebec service for hybridization with Affymetrix microarrays.
