Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
For this study we selected a gene, -synuclein (SNCA), that is consistently under-expressed in MCF7 cells and breast tumors. Following transfection with an SNCA expression construct, two stable MCF7 clones (named MCF7-SNCA #1 and 2) were selected and examined for expression differences relative to the parental MCF7 cells.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Carcinoma development in colorectal cancer (CRC) is driven by genetic alterations in numerous signaling pathways. Alterations in the RAS-ERK1/2 pathway are associated with the shortest overall survival for patients after diagnosis of CRC metastatic disease, but how RAS-ERK signaling regulates CRC metastasis is still unknown.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
The mRNA processing body is a cellular structure that regulates the stability of cytoplasmic mRNA. MARF1/LMKB is an RNA-binding protein that is associated with maintenance of mRNA homeostasis and genomic stability. To investigate the function of LMKB in a human B lymphocyte cell line, BJAB cells were treated with either control lentivirus or a lentivirus containing LMKB siRNA.
Publication Title
LMKB/MARF1 localizes to mRNA processing bodies, interacts with Ge-1, and regulates IFI44L gene expression.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Reactive oxygen species (ROS) are implicated in tumor transformation by modulating proteins involved in differentiation, proliferation and invasion. In order to identify genes that may support melanoma progression or regression after an antioxidant system (AOS) response, we developed and characterized a human melanoma cell model with different levels of ROS by stably overexpressing the antioxidant enzyme catalase in A375 amelanotic melanoma cells, and whole genome gene expression patterns were analyzed by microarrays.

Reprogramming human A375 amelanotic melanoma cells by catalase overexpression: Upregulation of antioxidant genes correlates with regression of melanoma malignancy and with malignant progression when downregulated.

- Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
We have used microarray technology to identify the transcriptional targets of Rho subfamily GTPases. This analysis indicated that murine fibroblasts transformed by these proteins show similar transcriptomal profiles. Functional annotation of the regulated genes indicate that Rho subfamily GTPases target a wide spectrum of biological functions, although loci encoding proteins linked to proliferation and DNA synthesis/transcription are up-regulated preferentially. Rho proteins promote four main networks of interacting proteins nucleated around E2F, c-Jun, c-Myc, and p53. Of those, E2F, c-Jun and c-Myc are essential for the maintenance of cell transformation. Inhibition of Rock, one of the main Rho GTPase targets, leads to small changes in the transcriptome of Rho-transformed cells. Rock inhibition decreases c-myc gene expression without affecting the E2F and c-Jun pathways. Loss-of-function studies demonstrate that c-Myc is important for the blockage of cell-contact inhibition rather than for promoting the proliferation of Rho-transformed cells. However, c-Myc overexpression does not bypass the inhibition of cell transformation induced by Rock blockage, indicating that c-Myc is essential, but not sufficient, for Rock-dependent transformation. These results reveal the complexity of the genetic program orchestrated by the Rho subfamily and pinpoint protein networks that mediate different aspects of the malignant phenotype of Rho-transformed cells

- Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
To characterize the transcriptome of the transcription factor AP4 DLD-1 cells were infected with AP4 coding viruses for different periods of time. Adenovirus amplification and purification was performed as previously described (He et al., 1998). The minimal amount of virus needed to reach more than 90% infection efficiency was determined by monitoring GFP signals with fluorescence microscopy. DLD-1 cells were infected in serum-free medium with adenovirus for 3 hours. After removal an equal amount of medium containing 20% FBS was added.
