Nutrient-dependent growth of NIH3T3 and NIH3T3 K-ras cell lines.

ABSTRACT: Expression profiling of normal NIH3T3 and transformed NIH3T3 K-ras cell lines grown for 72 hours in optimal glucose availability (25 mM glucose) or low glucose availability (1 mM). Low glucose induces apoptosis in transformed cells as compared to normal ones.

Nutrient-dependent growth of NIH3T3 and NIH3T3 K-ras cell lines.

Project description:Expression profiling of normal NIH3T3 and transformed NIH3T3 K-ras cell lines grown for 72 hours in optimal glucose availability (25 mM glucose) or low glucose availability (1 mM). Low glucose induces apoptosis in transformed cells as compared to normal ones. We performed genome-wide analysis by using Affymetrix GeneChip oligonucleotide microarrays to identify those genes whose expression levels are modulated by glucose availability in NIH3T3 and NIH3T3 K-ras cell lines. The cells, to be used for the transcription analysis, were collected at 18h from the initial seeding, time corresponding to the change of medium (25 or 1 mM glucose, indicated as T0) and then at 24, 48 and 72h upon medium change.

Expression data of mouse NIH3T3 and NIH3T3-k-ras transformed cell lines after Forskolin treatment

Project description:Forskolin treatment induces activation of protein kinase A. This activation protects transformed cells from death induced by glucose starvation. We used microarray to identify the mechanisms involved in such a pro-survival effect. NIH3T3 and NIH3T3-K-ras were plated at 1mM glucose and then daily treated or not with 10uM FSK until 72h of growth. The microarray analysis has been performed at 72h in order to identify specific mechanisms associate with transformed cells survival.

Transcription profiling of mouse NIH3T3 cells were compared with myc/ras transformed NIH3T3 cells and with IRF1 expressing myc/ras transformed cells

Project description:Interferons have been ascribed to mediate antitumor effects. IRF-1 is a major target gene of interferons. It inhibits cell proliferation and oncogenic transformation. Here we show that 60% of all mRNAs deregulated by oncogenic transformation mediated by c-myc and H-ras are reverted to the expression levels of non-transformed cells by IRF-1. These include cell cycle regulating genes. Activation of IRF-1 decreases cyclin D1 expression and CDK4 kinase activity concomitant with dephosphorylation of pRb. These effects of IRF-1 are mediated by inhibition of the MEK-ERK pathway and a transcriptional repression of cyclin D1. IRF-1 mediated effects on cell cycle progression were found to be overridden by ectopic expression of cyclin D1. Ablation of cyclin D1 by RNA interference experiments prevents transformation and tumor growth in nude mice. The data demonstrate that cyclin D1 is a key target for IRF-1 mediated tumor suppressive effects. Experiment Overall Design: 3 samples were analysed, two replicates per sample. NIH3T3 cells were compared with myc/ras transformed NIH3T3 cells and with IRF1 expressing myc/ras transformed cells.

Transcription profiling of mouse non-transformed cell (NIH3T3 + vector) and a transformed cell (NIH3T3 + Fbxo7).

Project description:The aim of this experiment was to get a comparison of the signatures between a non-transformed cell (NIH3T3 + vector) and a transformed cell (NIH3T3 + Fbxo7). NIH3T3 cells become transformed after the stable integration of the Fbxo7 gene. Fbxo7 potentiates cyclin D/cdk6 activity.

Transcription profiling of oncovav- and oncovav2-transformed NIH3T3 cells vs parental NIH3T3 controls

Project description:Effect of the overexpression of the oncogenic forms of the Vav2 and Vav proteins in the NIH3T3 cell line. oncovav- and oncovav2-transformed NIH3T3 cells are compared to the parental NIH3T3 controls under exponential growth conditions

Transcription profiling of mouse NIH3T3 cells transformed with oncovav2 deprived of Serum

Project description:Effect of the overexpression of the oncogenic form of the Vav2 protein in the NIH3T3 cell line under serum deprivation conditions. oncovav2-transformed NIH3T3 cells grown in serum-deprived medium (Vav2SD) are compared to the parental NIH3T3 controls under the same growth conditions (ContSD). Vav2SD cells are also compared to the oncovav2-transformed NIH3T3 cells growing exponentially and the NIH3T3 growing exponentially.

Expression profile of NIH3T3 cells overexpressing FOXP2 or a FOXP2 arrangement (FOXP2-CPED1)

Project description:To study the underlying mechanism of tumor initation driven by FOXP2, we performed transcriptome analysis of transformed NIH3T3 overexpressing FOXP2 or FOXP2-CEPD1 and control cells to explore the FOXP2-related transcriptome in tumorigenesis.

Circadian rhythm in NIH3T3 cells

Project description:Identification of cyclical expressed coding and non-coding genes during the circadian rhythm in NIH3T3 cells. NIH3T3 cells were synchronized for their circadian rhythm and RNA sequencing were performed at several time points along the rhythm. This data was used to identify cyclical expressed genes as well as long intergenic non-coding RNAs. NIH3T3 cells were synchronized with 100 nM Dexamethasone for 2 hours, then medium was changed to normal culture medium (0h). Every 4 hours cells were harvested, RNA isolated and RNAseq performed.
