RNAi knock down of the DNA-repair enzyme and transcriptional co-activator APE1 in human HeLa cells

ABSTRACT: Transcriptional profiling was done following APE1/Ref1 silencing using conditional gene expression knockdown by RNA interference (RNAi) technology in HeLa cell lines. APE1 is a DNA-repair enzyme and transcriptional co-activator. Knockdown leads to cell-growth arrest, apoptosis and impairment in the intracellular redox state and cytoskeletal perturbation.

Apurinic apyrimidinic endonuclease/redox effector factor 1 (APE1/Ref-1) protects cells from oxidative stress by acting as a central enzyme in base excision repair pathways of DNA lesions and through its independent activity as a redox transcriptional co-activator. Dysregulation of this protein has been associated with cancer development. At present, contrasting data have been published regarding the biological relevance of the two functions as well as the molecular mechanisms involved. Here, we ...[more]

The Polycomb Group Protein Suz12 Is Required for Embryonic Stem Cell Differentiation

Project description:Polycomb group (PcG) proteins form multiprotein complexes, called Polycomb repressive complexes (PRCs). PRC2 contains the PcG proteins EZH2, SUZ12, and EED and represses transcription through methylation of lysine (K) 27 of histone H3 (H3). Suz12 is essential for PRC2 activity and its inactivation results in early lethality of mouse embryos. Total RNA was extracted independently from three WT and three Suz12 KO ES cell clones. RNA was quantified, and equal amounts fromthe three Suz12 WT and the three Suz12 KO samples were pooled into one sample to reduce the experimental variation. Targets for microarray hybridization were synthesized according to the supplier’s instructions (Affymetrix). Hybridization, washing, staining, scanning, and data analysis were performed at the Affymetrix microarray unit at the Institute of Molecular Oncology of the Italian Foundation for Cancer Research-European Institute of Oncology campus, Milan, Italy, according to the manufacturer’s instructions.

Transcription profiling of colon mucosa from rats fed a high fat, high sucrose, low fibre diet with and without red wine polyphenols

Project description:In the experiment two groups of rats were compared. The control group consisted of 10 male, 5- to 6-weeks old, Fischer 344 (F344) rats (Nossan, Correzzana, Milan, Italy) fed a high fat, high sucrose, low fibre diet (control diet) for two weeks. This diet was based on the AIN76 diet [19], and was modified to contain 23% (w/w) fat (from corn oil) and a low level of cellulose (2% w/w), to mimic the high risk of colon cancer in human populations consuming high fat diets. The experimental group consisted of 10 male, 4- to 5-weeks old, F344 rats fed the same high fat diet as the control group in combination with 50 mg/kg red wine polyphenols for two weeks. The red wine polyphenol extract was prepared as described by Femia et al.<br> Total RNA was extracted using the RNeasy Midi kit (Qiagen, Milan, Italy). Equally amounts of RNA extracted from the colon mucosa of control diet-fed rats (n=10) were pooled and used as common reference for all hybridizations.

L1CAM overexpression in mouse lung endothelial cells (lECs)

Project description:In an attempt to elucidate the molecular mechanisms underlying the multiple roles of L1 in endothelium, we checked whether manipulating its expression affected the transcriptome of lECs. To this purpose, we compared the gene expression profiles of L1-overexpressing and control lECs by Affymetrix, which revealed a remarkable effect of L1 overexpression on lECs transcriptome. Mouse lung-derived EC (lECs), kindly provided by E. Dejana (Milan, Italy), were stably transfected with a pcDNA3.1/Hygro(-) vector containing mouse LICAM full length or with and empty pcDNA3.1/Hygro(-) vector as control. Three independent experimental replicates were performed.

siRNA profiling of stable HCT116-siTop1 and MCF-7-siTop1 cell lines reveal non-classical functions of human Topoisomerase I:

Project description:The biological functions of nuclear topoisomerase I (Top1) have been difficult to study because knocking out TOP1 is lethal in metazoans. To reveal the functions of human Top1, we have generated stable Top1siRNA cell lines from colon and breast carcinomas (HCT116-siTop1 and MCF-7-siTop1, respectively). In those cells, Top2 compensates for Top1 deficiency. A prominent feature of the siTop1 cells is genomic instability, with chromosomal aberrations and histone gamma-H2AX foci associated with replication. siTop1 cells also show rDNA and nucleolar alterations, and increased nuclear volume. Genome-wide transcription profiling revealed 55 genes with consistent changes in siTop1 cells. Among them, asparagine synthetase (ASNS) was reduced in siTop1 cells, as it also was in cells with transient Top1 downregulation. Conversely, Top1 complementation increased ASNS, indicating a causal link between Top1 and ASNS expression. Correspondingly, pharmacological profiling showed l-asparaginase hypersensitivity in the siTop1 cells. Resistance to camptothecin, aphidicolin, hydroxyurea and staurosporine, and hypersensitivity to etoposide and actinomycin D demonstrated that Top1, in addition to being the target of camptothecins, also regulates DNA replication, rDNA stability and apoptosis. Overall, our studies demonstrate the pleiotropic nature of human Top1 activities. In addition to its classical DNA nicking-closing functions, Top1 plays critical non-classical roles in genomic stability, gene-specific transcription, and response to various anticancer agents. Experiment Overall Design: We are using Affymetrix whole genome array U133 Plus 2, which is a single color microarray platform. For colon experiments, we analyzed 2 different samples as 4 replicates. For breast experiments, we analyzed 2 samples as replicates.

Coexpression of CD49b and LAG-3 identifies human and mouse T regulatory type 1 cells

Project description:CD4(+) type 1 T regulatory (Tr1) cells are induced in the periphery and have a pivotal role in promoting and maintaining tolerance. The absence of surface markers that uniquely identify Tr1 cells has limited their study and clinical applications. By gene expression profiling of human Tr1 cell clones, we identified the surface markers CD49b and lymphocyte activation gene 3 (LAG-3) as being stably and selectively coexpressed on mouse and human Tr1 cells. We showed the specificity of these markers in mouse models of intestinal inflammation and helminth infection and in the peripheral blood of healthy volunteers. The coexpression of CD49b and LAG-3 enables the isolation of highly suppressive human Tr1 cells from in vitro anergized cultures and allows the tracking of Tr1 cells in the peripheral blood of subjects who developed tolerance after allogeneic hematopoietic stem cell transplantation. The use of these markers makes it feasible to track Tr1 cells in vivo and purify Tr1 cells for cell therapy to induce or restore tolerance in subjects with immune-mediated diseases. The transcriptome of human Tr1 cell clones to that of TH0 cell clones either unstimulated or stimulated for 6 and 16 h. Tr1 and TH0 cell clones were isolated from peripheral blood of 2 Healthy Donors (HDs). mRNA from T cell clones unstimulated (t0, n=4 Tr1 cell clones and n=10 TH0 cell clones) or stimulated with immobilized anti-CD3 and soluble anti-CD28 mAbs (6h and 16h, n=4 Tr1 cell clones and n=5 TH0 cell clones) was isolated. Differential expression of 28869 genes was investigated by whole transcript Affymetric chips.

Transcription profiling of human neuroblastoma cell lines under normoxic and hypoxic conditions

Project description:Hypoxia is a low oxygen condition that occurs in the developing tumor mass and that is associated with poor prognosis and resistance to chemo- and radio-therapy. The definition of the hypoxia gene signature is fundamental for the understanding of tumor biology, as in the case of neuroblastoma, the most common pediatric solid tumor. The issue of identifying a significant group of variables in microarray gene expression experiments is particularly difficult due to the typical high dimensional nature of the data and great effort has been spent in the development of feature selection techniques. Our main goal is to define a robust hypoxia gene signature in neuroblastoma cell lines. A set of 9 neuroblastoma cell lines were cultured under normoxic and hypoxic conditions for 18 hours, and their gene expression profiles were measured with Affymetrix GeneChip HG-U133 Plus 2.0. The clustering analysis of the expression profiles based on different clustering methods consistently revealed that hypoxia was not the major factor characterizing the data set. T-test analysis with multiple testing correction fails to identify significantly differentially expressed genes. Conversely the l1-l2 regularization selects 11 significant probesets while building an effective classification rule. The algorithm is cast within a cross-validation framework in order to achieve an unbiased analysis. The estimated cross-validation error is 17% (3 out of 18). We show that the use of l1-l2 regularization allowed us to model the effect of hypoxia, which was not detected by conventional t-test based approaches and we find a panel of genes able to properly discriminate the normoxic versus the hypoxic status of neuroblastoma cell lines. Experiment Overall Design: The expression profile of 9 neuroblastoma cell lines under normoxia vs hypoxia was studied
