Gene expression patterns induced by 5-Fluorouracil in breast cancer cell lines

ABSTRACT: We have compared the changes in cell cycle and cell death parameters induced by 2 different concentrations of 5-FU (IC50 and IC80) in the breast adenocarcinoma cell line MCF7. G1/S cell cycle arrest was associated with both concentrations, whereas cell death was mainly induced after IC80 5-FU. These changes were correlated with gene expression assessed by cDNA microarray analysis. Main findings included an overexpression of p53 target genes involved in cell cycle and apoptosis (CDKN1A/p21, TP53INP, TNFRSF6/FAS and BBC3/PUMA), and significant repression of Myc. High dose 5-FU also induced a higher regulation of the mitochondrial death genes APAF1, BAK1 and BCL2, and induction of genes of the ID family. Time and dose-dependent changes in gene expression, induced by 5-Fluorouracil, in breast carcinoma cell lines MCF7, and MDA-MB-435.

The availability of oral precursors of 5-Fluorouracil (5-FU) and its favorable results in treating advanced breast cancer have renewed the interest in the molecular mechanisms underlying its cytotoxicity. We have compared the changes in cell cycle and cell death parameters induced by 2 different concentrations of 5-FU (IC50 and IC80) in the breast adenocarcinoma cell line MCF7. G1/S cell cycle arrest was associated with both concentrations, whereas cell death was mainly induced after IC80 5-FU. ...[more]

Project description:The self-renewal and differentiation potential of human embryonic stem cells (hESCs) suggests that hESCs could be used for regenerative medicine, especially for restoring neuronal functions in brain diseases. However, the functional properties of neurons derived from hESC are largely unknown. Moreover, since hESCs were derived under diverse conditions, the possibility arises that neurons derived from different hESC lines exhibit distinct properties, but this possibility remains unexplored. To address these issues, we developed a protocol that allows step-wise generation from hESCs of ~70-80% pure human neurons that form spontaneously active synaptic networks in culture. Comparison of neurons derived from the well-characterized HSF1 and HSF6 hESC lines revealed that HSF1- but not HSF6-derived neurons exhibit forebrain properties. Accordingly, HSF1-derived neurons initially form primarily GABAergic synaptic networks, whereas HSF6-derived neurons initially form glutamatergic networks. microRNA profiling revealed significant expression differences between the two hESC lines, suggesting that microRNAs may influence their distinct differentiation properties. These observations indicate that although both HSF1 and HSF6 hESCs differentiate into functional neurons, the two hESC lines exhibit distinct differentiation potentials, suggesting that they are pre-programmed. Information on hESC line-specific differentiation biases is crucial for neural stem cell therapy and establishment of novel disease models using hESCs. Experiment Overall Design: We directly compared the transcriptome of hNPCs derived from HSF-1 and HSF-6 hESC lines under two different neural induction conditions (embryonic body formation in presence of caudalizing factors (retinoic acid and bFGF) and monolayer conversion in presence of BMP signaling inhibitor (Noggin)). Since HSF6 hESC cannot undergo efficient neural differentiation without caudalizing factors, we cannot obtain RNA samples for HSF6 (Noggin). Experiment Overall Design: In summary, consistent with our immunostaining results, HSF1 hNPCs display more forebrain properties as compared to HSF6 hNPCs, indicated by expression of multiple forebrain specific markers. Conversely, HSF6 hNPCs show regional identity towards posterior central nervous system.

Project description:Werner syndrome (WS) is a rare disorder characterized by the premature onset of a number of age-related diseases. The gene responsible for WS is believed to be involved in different aspects of transcription, replication, and/or DNA repair. The poly(ADP-ribose) polymerase-1 (PARP-1) enzyme is also involved in DNA repair and is known to affect transcription of several genes. In this study, we examined the expression profile of cells lacking the normal function of either or both enzymes. All mutant cells exhibited altered expression of genes normally responding to oxidative stress. Interestingly, more than 58% of misregulated genes identified in double mutant cells were not altered in cells with either the Wrn or PARP-1 mutation alone. Consequently, the impact on gene expression profile when both Wrn and PARP-1 are mutated was greater than a simple addition of individual mutant genotype. In addition, double mutant cultured cells showed major misregulation of genes involved in apoptosis, cell cycle control, embryonic development, metabolism, and signal transduction. More importantly, in vivo analyses of double mutant mice have confirmed the increased apoptosis and the developmental defects in embryos as well as the major increase in intracellular phosphorylation and oxidative DNA damage in adult tissues. They also exhibited a progressive increase in oxidative stress with age. Thus, a major result of this study is that changes in expression of several genes and physiological functions identified in vitro were confirmed in mouse embryonic and adult tissues. Experiment Overall Design: Microarray analyses were performed on cell cultures at the second passage (10 population doublings). For each genotype, asynchronously dividing cells derived from three healthy 15.5 day embryos from one litter were pooled at the second passage and cytoplasmic RNA was extracted. Cytoplasmic RNA was used in these experiments to avoid contamination with heterogeneous nuclear RNA and genomic DNA. (Note that DNAse treatment was also applied to all samples). This pool of RNA was labeled sample number 1 for each genotype. Pooling of embryonic cells was performed to minimize the effect of inter-individual biological differences. A second pool of embryonic cells was also created from a separate dam (second litter) for each genotype (called samples number 2). This strategy allowed obtaining samples in duplicate for each genotype. The cRNA from wild type cells were synthesized with Cy-5 labeled nucleotides and cRNAs from Wrn mutant, PARP-1 null, and PARP-1 null/Wrn mutant cells were synthesized with Cy-3 labeled nucleotides. Hybridization was performed on Mouse Agilent 60-mer Oligo Microarray chips by mixing wild type labeled cRNA (baseline expression levels) with either Wrn mutant, PARP-1 null, or PARP-1 null/Wrn mutant cRNA. Hybridization experiments were done in duplicates.
