Project description:We are interested in having the gene microarray done on untreated and PMA treated (10 nM x 24 hr) human and mouse epithelial cells lines including CALU-3, MLE-15, primary bronchial human airway epithelial cells. We are especially interested in seeing whether sialyl or sulfo transferases, and MUC genes, are present and if they are induced by PMA. We hope to use this information to optimize future experiments designed to identify Siglec lung ligands.

Project description:We were interested in investigating the transcriptome responses to exogenous applications of brassinosteroid hormone when Arabidopsis seedlings are pre-stressed with a reactive oxygen species, hydrogen peroxide. We were interested in seeing which subsets of BR-responsive gene transcripts were most affected and how BR-responsive gene transcripts responded to increasing concentrations of hydrogen peroxide both as a whole and individually.

Project description:Human histomonocytic U937 cells exhibit macrophage-like properties after phorbol ester stimulation. Accumulating evidence demonstrated that remarkable number of transcripts changed in their amount at total RNA levels. However, post-transcriptional regulation has not been fully elucidated in this model. Thus, we compared expression profiles between polysomal and cytoplasmic RNAs before and after phorbol 12-myristate 13-acetate stimulation (48h, 32nM).

Project description:ZXDC1 augments the expression of various markers of monocyte/macrophage differentiation when over-expressed in the U937 cell line treated with the phorbol ester PMA. Likewise, knockdown of ZXDC1 restricts the induced expression of these markers. We sought to identify specfic gene targets of ZXDC1 during the process of monocyte/macrophage differentiation in U937 by performing gene expression profiling in cells exhibiting reduced expression of ZXDC1 compared to controls. We used microarray to identify genes regulated by ZXDC during PMA-induced differentiation of U937 monoblasts towards a monocyte/macrophage phenotype An inducible shRNAmir (Tet-On) cell line was established in the U937 background that displayed significant, reproducible, and doxycycline inducible knockdown of ZXDC1. Using this cell line, we created four experimental groups to identify gene targets of ZXDC1 during PMA-induced differention towards a monocyte/macrophage phenotype: Vehicle alone; Vehicle+Doxycycline; PMA alone; PMA+Doxycycline. Each independent group was used for RNA extraction and hybridization on Affymetrix microarray chips.

Project description:We were interested in investigating the transcriptome responses to exogenous applications of brassinosteroid hormone when Arabidopsis seedlings are pre-stressed with a reactive oxygen species, hydrogen peroxide. We were interested in seeing which subsets of BR-responsive gene transcripts were most affected and how BR-responsive gene transcripts responded to increasing concentrations of hydrogen peroxide both as a whole and individually. Liquid culture Arabidopsis seedlings are grown under standard conditions. Hydrogen peroxide is added at various concentrations to pre-stress the seedlings. Following this pretreatment, the seedlings are then treated with brassinosteroid (BR) hormone (epi-brassinolide, BL). Following this treatment, seedlings are harvested and total RNA is extracted for genome-wide transcriptome analysis.

Project description:Low-level infection is believed to play a role in the degradation of the outer blood retinal barrier, which is composed of retinal pigment epithelial (RPE) cells. By investigating immunopathogenic West nile virus (WNV) infected RPE via microarray, we sought to find key genes involved in a low-level viral infection, which are vital for normal immune responses. We infected primary human RPE cells and an human RPE cell line with WNV and extracted RNA to hybridize onto Affymetrix arrays. We were interested in the global expression of differentially regulated genes in WNV infected RPE cells, at 24h post infection. We were also interested in seeing the differences in response between infected primaries and the infected ARPE19 cell line.
