U937 cells: Control treated LPS vs. Co-cultured Panc-1 cells

Project description:We collected U937 cells after 72 h of LPS treatment or 72 h of co-culture with PANC-1 cells for microarray analysis. The gene microarray data were analyzed using the Agilent Human whole genome oligo 4*44k chip (array kit serial number: US00082833) and Agilent’s gene expression microarray software, including Feature Extraction and GeneSpring GX. Feature Extraction software extracts data from microarray images and provides workflows for analysis. GeneSpring GX offers statistical tools for data analysis and visualization (Welgene Biotech), and the genes of interest were drawn as a heatmap.

Real-time quantitative PCR analysis of differentiated U937 cells stimulated with LPS+IFNgamma

Project description:U937 monocyte cell line was differentiated using PMA. Differentiated U937 monocytes were exposed to MEM+10% FBS medium (untreated cells) and the same medium containing LPS+IFNgamma. The changes in the gene expression of cytokines and chemokines were evaluated using RT2 Profiler qPCR array

U937 cells: differentiating vs. undifferentiated

Project description:Gene-expression changes in U937 cells undergoing monocytic differentiation with TPA treatment Keywords: differentiation treatment The promonocytic U937 cell line was maintained at 37C in RPMI 1640 medium (Mediatech) supplemented with 10% fetalclone (HyClone) under a 5% CO2, 95% air atmosphere. U937 cells were differentiated by the addition to the growth medium 100 nM 12-O-tetradeconoyl-phorbol 13-acetate (TPA) (Sigma).Three condition experiment, treated with TPA for two different time points (27 and 96 hrs) vs. untreated. Biological replicates: independently grown, treated and harvested

B27 modulation of LPS response

Project description:Objectives How HLA-B27 contributes towards arthritis susceptibility is still unclear, but effects on the response to bacteria unrelated to the classical antigen presenting role of B27 have been suggested. This study investigated whether HLA-B27 modulates the innate response to LPS, a component shared between all Gram –ve bacteria that can trigger reactive arthritis. Methods Pools of U937 transfectants expressing either HLA-B27, HLA-A2, or the expression plasmid alone were differentiated with PMA and stimulated with LPS. Supernatants were analysed for TNF-alpha secretion and the gene expression profiles of unstimulated and LPS stimulated cells were determined by microarray analysis. Changes in gene expression that are indicative of an unfolded protein response were also analysed by quantitative PCR. Results TNF-alpha secretion, a biological marker of the inflammatory response to LPS, was not significantly different between U937-B27 and U937-control. No differences in gene expression between unstimulated U937- B27 and U937-control lines were detected. Both U937-control and U937-B27 exhibited a stereotypic response to LPS. Only 1 gene, OAS2, was differentially expressed by these cell lines, and this was confirmed by quantitative PCR. Analysis of XBP-1 splicing suggested that a small increase in the unfolded protein response is induced following LPS stimulation, but this increase was seen in all transfectants. Conclusions The expression of B27 does not profoundly alter gene expression following LPS stimulation. Therefore, additional signals, such as those provided by cytokines or intracellular infection, may be required to reveal any influence of B27 expression on the inflammatory response.

The miRNA profiling in PANC-1, PANC-1 GEM 100 and PANC-1 GEM1500 cells

Project description:Gemcitabine has been a first-line therapeutic agent for pancreatic ductal adenocarcinoma (PDAC) pancreatic cancer; however, acquisition of resistance to gemcitabine remains a major challenge. We analyzed miRNAs expression profiles by array-based miRNAs analysis between gemcitabine–resistant (PANC-1/GEM) and parental PANC-1 cells.

Expression analysis of RNAi mediated ALPPL2 knockdown in ALPPL2 expressing Panc-1 cells (Panc-1+ve)

Project description:Analysis of differentially expressing genes in whole genome wide analysis of ALPPL2 expressing Panc-1 cells (Panc-1+ve) via siRNA mediated knockdown of ALPPL2 Panc-1 +ve and Panc-1-ve cell lines were generated from Panc-1 cell line based upon its hetergenous binding to aptamer SQ2. Detailed procedure of generation of these cell lines are described in Pooja Dua, Hye Suk Kang, Seung-Mo Hong, Ming-Sound Tsao, Soyoun Kim, and Dong-ki Lee. 2012 Alkaline Phosphatase ALPPL2 is a novel pancreatic carcinoma-associated protein.
