Expression data from mesothelial (LP9) and mesothelioma cells (HMESO) inhibited for extracellular-regulated kinase (ERK) 1, 2, or 5

ABSTRACT: Extracellular-regulated kinases (ERK1/2 and 5) are known to play important roles in growth and drug resistance of various cancers. Here we show roles of inhibition of ERK1, ERK2, or ERK5 on gene expression profiles of epithelioid malignant mesothelioma (MM) cells (HMESO). Untransfected human mesothelial cells (LP9), MM cells (HMESO) or HMESO cells stably transfected with shControl, shERK1, shERK2 , or shERK5 plasmids were used. Microarrays were performed on samples from 3 independent experiments. Each sample was analyzed on a separate array (3 independent biological replicates).

<h4>Background</h4>Malignant mesotheliomas (MM) have a poor prognosis, largely because of their chemoresistance to anti-cancer drugs such as doxorubicin (Dox). Here we show using human MM lines that Dox activates extracellular signal-regulated kinases (ERK1 and 2), causally linked to increased expression of ABC transporter genes, decreased accumulation of Dox, and enhanced MM growth. Using the MEK1/2 inhibitor, U0126 and stably transfected shERK1 and shERK2 MM cell lines, we show that inhibition ...[more]

Genomic Collaboration of Estrogen Receptor-Î± and ERK2 in Regulating Gene and Proliferation Programs

Project description:The nuclear hormone receptor, estrogen receptor-alpha (ERÎ±), and MAP kinases both play key roles in hormone-dependent cancers, yet their interplay and the integration of their signaling inputs remain poorly understood. In these studies, we document that estrogen-occupied ERÎ± activates and interacts with ERK2, a downstream effector in the MAPK pathway, resulting in ERK2 and ERÎ± colocalization at chromatin binding sites across the genome of breast cancer cells. KEYWORDS: siRNA knock-down, ligand treatment MCF-7 human breast adenocarcinoma cells were tranfected with control, ERK1 and ERK2 siRNA for 60 hours and treated with 0.1% EtOH (Vehicle) or 10 nM E2 for 4 hours or 24 hours, and cDNA microarray analyses were carried out using Affymetrix [HG-U133A_2] Affymetrix Human Genome U133A 2.0 Array.

Context-dependent regulatory mechanisms control site-specific information processing within the MEK/ERK module

Project description:The impact of the cellular context and receptor type on the dynamics of phosphorylation cycles in signaling pathways are unclear. We employ an unbiased approach to identify network alterations that explain phosphorylation dynamics of the MEK/ERK module in response to hepatocyte growth factor or interleukin-6, comparing primary hepatocytes with the immortalized cell line HaCaT. By combining quantitative mass spectrometry with dynamic modeling, we elucidate the network structure in primary hepatocytes. For HaCaT, our model predicts additional dual feedback regulation, which we experimentally identify as DUSP6 and paxillin. Model analyses reveal switch-like ERK phospho-form distribution profiles in primary hepatocytes that are severely altered in HaCaT, explaining threshold, sensitivity and saturation behavior. We apply our approach to human hepatocellular carcinoma samples and identify, as predicted, elevated threonine-phosphorylated ERK levels in the tumor. This suggests that the prevalence of the mono-phosphorylated ERK rather than the doubly phosphorylated ERK is indicative for dysregulated proliferation.

ERK Oscillation-Dependent Gene Expression Patterns and Deregulation By The Stress-Response

Project description:Studies were undertaken to determine whether oscillatory behavior in the extracellular signal regulated kinase (ERK) pathway results in unique gene regulation patterns. Microarray analysis was performed on three subcloned populations of human keratinocytes with distinct ERK signaling/oscillation phenotypes. Microarray analysis identified 45 genes that overlapped between 2 subclones with oscillation phenotypes but not in the subclone which is non-oscillatory. Transcription factor networks revealed a role for MED1 in mediating ERK oscillation-dependent gene expression, which was confirmed with Western blot analysis. Further experimentation confirmed a role for p38 in the mediation of MED1 phosphorylation and ERK oscillatory behavior. hTERT-immortalized normal human keratinocytes (provided by Dr. Jerry Shay, The University of Texas Southwestern Medical Center) were stably transfected with ERK1-green fluorescent protein chimera and stable subclones were isolated with distinct ERK activation/oscillation patterns: Clone #1 exhibits transient ERK activation with ligand activation but does not oscillate; Clone #2 exhibits persistent ERK oscillations that are dependent on ligand activation; and Clone #3 exhibits spontaneous ERK oscillations in the absence of ligand activation.

A chemoproteomics approach to discover regulators of innate immune signaling

Project description:Viral dsRNA binds to Retinoic acid Inducible Gene I (RIG-I) Like Receptors (RLRs), promoting the production of Interferon (IFN). Interferon then stimulates the innate and adaptive immune system in an autocrine and paracrine manner. Outside of conical pathways, regulators of the interferon (IFN) activation/response system are poorly characterized. In this study, we used a discovery-biased approach to identify Kinases that are part of the interferon system. Differential changes in phosphorylation sites, in the context of dsRNA RIG-I stimulation, were identified with unbiased mass-spec biased phospho-proteomics. We then computationally identified several Kinases upregulated after RIG-I stimulation from phospho-proteomics data. A Chemoproteomics screen was then used to characterize the altered interferon response in the presence of Kinases inhibitors for the upregulated kinases. Combining unbiased phosphoproteomics with a chemoproteomics screen, we identified several potentially novel regulators of the Interferon system whose inhibition blocked the production of Interferon Stimulated Genes.

Gene expression profiles in MexTAg transgenic mouse and wild type mouse asbestos-induced mesothelioma

Project description:Malignant mesothelioma is an aggressive tumour arising from the mesothelial cells lining the pleura, peritoneum or pericardium. The principal carcinogen associated with malignant mesothelioma is asbestos . A transgenic mouse model, denoted MexTAg, which encodes the Simian Virus 40 (SV40) large T antigen (TAg) downstream of the mesothelin promoter was developed. Inactivation of the tumour suppressors p53 and RB following binding to TAg results. In this model mesothelioma develops in the mesothelial cell compartment after the mice have been exposed to asbestos. The MexTAg transgenic mouse model of mesothelioma model enables analysis of the molecular events associated with asbestos induced mesothelioma and is utilised here to investigate the molecular dynamics of tumours induced in these mice, using gene expression patterns as a read out.

Characterizing the molecular spatial and temporal field of injury in early stage smoker non-small cell lung cancer patients after definitive surgery by expression profiling

Project description:Gene expression alterations in response to cigarette smoke have been characterized in normal-appearing bronchial epithelium of healthy smokers and it has been suggested that adjacent histologically normal tissue display tumor-associated molecular abnormalities. We sought to delineate the spatial and temporal molecular lung field of injury in smoker early stage non-small cell lung cancer (NSCLC) patients (n=19) who were accrued into a surveillance clinical trial for annual follow-up and bronchoscopies within one year after definitive surgery. Bronchial brushings and biopsies were obtained from six different sites in the lung at the time of inclusion in the study and at 12, 24 and 36 months after the first time point. Affymetrix Human Gene 1.0 ST arrays were used for whole-transcript expression profiling of airways (n=391). Mixed-effects models were performed to determine significant differential gene expression modulation by site from tumor and time following inclusion in the study within the molecular field of injury.

Gene expression of HCT116 cells after stimulation with oncostatin M (OSM)

Project description:To evaluate gene expression profiles in intestinal epithelial cells (IEC) after OSM stimulation, we have employed whole genome microarray expression profiling as a discovery platform to identify relevant genes which are potentially of interest to reveal the role of OSM in intestinal inflammation. The most strongly up-regulated genes were SERPINS, which belong to the family of serin peptidase inhibitors with antiprotease activities, most of them serine and cysteine proteases. SERPINB4, SERPINB3 and SERPINA3 were the genes with the strongest up-regulation, also verified in qPCR. OSM-induced SERPIN up-regulation may contribute to anti-apoptotic and proliferative effects of OSM in IEC. HCT116 cells were starved overnight with medium containing 1% FCS after reaching 70% confluency. On the next day, cells were stimulated in quadruplicates with 100 ng/mL OSM or left unstimulated. RNA was isolated 6 hours after stimulation and RNA concentration and purity was measured.

RNA-seq of canine MDCK epithelial cell line compared to cell line overexpressing ERK2 or cell line with conditional activation of the ERK pathway

Project description:Using RNA-seq and canine MDCK epithelial cells, we analyzed mRNA expression profiles of cells overexpressing ERK2 and cells where the ERK pathway was activated for 24 hrs. For this purpose, three cell lines were used: parental MDCK cells, MDCK cells overexpressing FLAG-ERK2 or MDCK cells expressing conditionally active Raf protein (ΔRaf1:ER). Activation of the ERK pathways was achieved by the addition of 4-Hydroxytamoxifen that converts ΔRaf1:ER protein to the active form and it subsequently activates the ERK pathway.
