Project description:Lung cancer cell line, A549 cells, was transfected with siPML or siCtrl for 48hr to knockdown PML expression. WDR4 or vector was overexpressed in A549 cells for 48hr. These four sets of cells were then subjected to microarray profiling using the Human OneArray microarray (version HOA6.1, GEO Platform GPL19137) from Phalanx Biotech Group.

Project description:Background: α-catulin may functions as an oncoprotein, sustaining proliferation by preventing cellular senescence and promoting cancer cell migration. In this study, we investigated the mechanism of α-catulin in cancer cell migration and metastasis in lung cancer. Method: α-catulin mRNA expression was isolated from A549/AS2neo (control) and A549/AS2neo-α-catulin stable cells. The Phalanx Human OneArray microarray analysis was performed to identify α-catulin downstream genes. Results: Overexpression of α-catulin increased cancer cell migration and metastasis. By using Phalanx Human OneArray microarray we have identified panel of genes altered by α-catulin overexpression, consisting of CDC42, intergrins and genes related to cytoskeleton remodeling. Conclusion: α-catulin is an oncoprotein and promotes lung cancer cell migration and metastasis. Two-condition experiment, Vector vs. alpha-catulin overexpression cells.The cDNAs encoding full-length human alpha-catulin were amplified and subcloned into lentiviral pLKO_AS2.neo which generated full-length alpha-catulin. Vector control or alpha-catulin lentivirus were transduced into A549 cells and G418 was used to select stable cells.

Project description:HO-1 cells denote the cultured rat mesangial cells with heme oxygenase-1 knocked down by RNA interference (using lentiviral vector). GFP cells denote the cultured rat mesangial cells that are transfected with empty lentiviral vector containing GFP cassette. Cells are treated with hydrogen peroxide 100 micromolar for 2 hours, or without. RNA are then harvested for array analysis. Biological replicates are performed (two independent experiment sets). GFP cell and HO-1 cell are untreated, or treated with hydrogen peroxide (100 micromolar for 2 hours).

Project description:Since infectious diseases caused by Staphylococcus aureus are still a major threat for human health we aimed to gain a detailed understanding of the molecular interplay of pathogen and host upon internalization by proteome analyses. In the present study we infected human alveolar epithelial A549 cells with S. aureus HG001 pMV158GFP and separated intact bacteria from host cell debris or infected from non-infected A549 cells prior to proteome analysis by cell sorting thus facilitating detailed analyses. During the first 6.5 h in the intracellular milieu S. aureus displayed reduced growth rate, induction of the stringent response, and adaptation to microaerobic conditions as well as cell wall stress. Interestingly, both truly infected host cells and those only potentially exposed to secreted S. aureus proteins but not infected displayed differences in the proteome pattern compared to A549 cells which had never been in contact with S. aureus. However, adaptation reactions were more pronounced in infected compared to non-infected A549 cells. Additional cytokine measurements revealed elaborated levels of pro-inflammatory cytokines in supernatants of the infection setting compared to pure host cell cultures which might mediate communication among the host cells and trigger adaptation even in cells not infected with S. aureus.

Project description:In our present study, we found that lncRNA-hPVT1 could promote HCC cell proliferation. We want to know what were the target genes of lncRNA-hPVT1. So we constructed the hPVT1-overexpressed SMMC-771 cells and observed the mRNA profile in hPVT1-overexpressed and control SMMC-771 cells. lncRNA-hPVT1 induced transcriptional changes in SMMC-7721. Two-condition experiment, control (LV-Control) vs lncRNA-hPVT1 expression (LV-hPVT1 Clone2 ). Each has 3 biological repeats.

Project description:The differentially expressed genes among the blank control, ascites mouse model, Daji (DJ)/ Gancao (GC)-synergistic treatment and DJ/GC-antagonistic treatment groups were identified to investigate the molecular mechanisms underlying the herb pair DJ and GC acting on ascites mice. In the study, 50 male Kunming mice were randomly divided into 5 groups, namely, normal control group, model group, Daji/Gancao-synergy group, Daji/Gancao-antagonism group, Daji group. Normal control group and model group were intragastrically administrated with normal saline, while other 3 groups were intragastrically administrated with corresponding doses.

Project description:To predict the different genes, this study compared the gene expression level among the control group, the model group and the treatment groups. In this present study, 20 Wistar rats, weighting 160-180g and as the sex evenly, were randomly divided into five groups: normal control group, model control group , Haizao Yuhu decoction group, Haizao Yuhu decotion lacking Sargassum fusiforme (DL-S) group, and Haizao Yuhu decotion lacking Radix Glycyrrhiza (DL-G) group. Except the rats in control and model groups, the three other groups, which were established as goiter model, were administered appropriate medication at the dose of 1mL/100g for 28 consecutive days. After all animals sacrificed, thyroids were removed and then put in Trizol for microarray experiments.

Project description:FGF21 is a novel secreted protein with robust anti-diabetic, anti-obesity, and anti-atherogenic activities in preclinical species. In the current study, we investigated the signal transduction pathways downstream of FGF21 following acute administration of the growth factor to mice. Focusing on adipose tissues, we identified FGF21-mediated downstream signaling events and target engagement biomarkers. Specifically, RNA profiling of adipose tissues and phosphoproteomic profiling of adipocytes, following FGF21 treatment revealed several specific changes in gene expression and post-translational modifications, specifically phosphorylation, in several relevant proteins. Affymetrix microarray analysis of white adipose tissues isolated from both C57BL/6 (fed either regular chow or HFD) and db/db mice identified over 150 robust potential RNA transcripts and over 50 potential secreted proteins that were changed greater than 1.5 fold by FGF21 acutely. Phosphoprofiling analysis identified over 130 phosphoproteins that were modulated greater than 1.5 fold by FGF21 in 3T3-L1 adipocytes. Bioinformatic analysis of the combined gene and phosphoprotein profiling data identified a number of known metabolic pathways such as glucose uptake, insulin receptor signaling, Erk/Mapk signaling cascades, and lipid metabolism. Moreover, a number of novel events with hitherto unknown links to FGF21 signaling were observed at both the transcription and protein phosphorylation levels following treatment. We conclude that such a combined "omics" approach can be used not only to identify robust biomarkers for novel therapeutics but can also enhance our understanding of downstream signaling pathways; in the example presented here, novel FGF21-mediated signaling events in adipose tissue have been revealed that warrant further investigation. Three mouse strains (C57BL6 on chow diet, C57BL6 on high fat diet, and db/db on chow diet) were treated with either vehicle, wild-type FGF21, or pegylated FGF21 acutely or for several days and three white adipose tissues (IWAT, EWAT, RPWAT) and brown adipose tissue (BAT) were profiled on custom Affymetrix microarrays. The primary goal was to identify robust and consistent acute target engagement biomarkers of FGF21 activation in white adipose tissues.

Project description:Inhibition of Diacylglycerol O-acyltransferase 1 (DGAT1) has been a mechanism of interest for metabolic disorders. DGAT1 inhibition has been shown to be a key regulator in an array of metabolic pathways; however, based on the DGAT1 KO mouse phenotype the anticipation is that pharmacological inhibition of DGAT1 could potentially lead to skin related adverse effects. One of the aims in developing small molecule DGAT1 inhibitors that target key metabolic tissues is to avoid activity on skin-localized DGAT1 enzyme. In this report we describe a modeling-based approach to identify molecules with physical properties leading to differential exposure distribution. In addition, we demonstrate histological and RNA based biomarker approaches that can detect sebaceous gland atrophy pre-clinically that could be used as potential biomarkers in a clinical setting. Mice were treated with DGAT1 inhibitors for 14 days and dorsal skin biopsies (3-5 mm^2) were taken. RNA was profiled on custom Affymetrix microarrays. The primary goal was to identify robust and consistent biomarkers of DGAT1 inibition in skin.
