Cross species hybridization of human cancer cells co-cultured with mouse astrocytes and fibroblasts (Illumina mouse-6)

ABSTRACT: Brain metastases are highly resistant to chemotherapy. Brain metastases are surrounded and infiltrated by activated astrocytes. To examine the genes whose expression is associated with chemo-resistance of brain-metastasized cancer cells, gene expression data were collected and analyzed from breast cancer cells and lung cancer cells co-cultured with astrocytes. Fibroblast cells were used as control. Total RNAs were extracted from co-cultured cells and hybridized to human microarray and mouse microarrays to detect human cell and mouse cell specific gene expression data.

Gene expression profile of Serially Mixed samples of MDA-MB231 and Mouse Astrocytes

Project description:To test specificity of human microarray probes against mouse mRNA serially mixed human MDA-MB231 cancer cells' mRNAs with mouse Astrocytes were hybridized against human microarray and vice versa by changing the ratios of human and mouse samples from 100% to 0%. Mixed human: 1 MDA-MB231, 1 MDA231_Astro(91), 2 MDA231_Astro(73), 2 MDA231_Astro(55),2 MDA231_Astro(37),1 MDA231_Astro(19), 1 Astrocytes Mixed mouse: 1 MDA-MB231, 1 MDA231_Astro(91), 2 MDA231_Astro(73), 2 MDA231_Astro(55),2 MDA231_Astro(37),1 MDA231_Astro(19), 1 Astrocytes

Cross species hybridization of human cancer cells xenografted into different mouse organ sites

Project description:To test gene expression changes of human cancer cells and mouse surrounding tissue cells during tumor progression, 4 different types of cancer cells (MDA-MB231Br3, PC14Br4, KM12M, A375SM) were injected into mouse brain, skin and orthotopic sites. RNAs containing human cancer cells and mouse surrounding tissue cells were extracted and hybridized into human and mouse arrays at the same times and it revealed the brain microenvironment induced complete reprogramming of metasized cancer cells, resulting in a gain of neuronal cell characteristic , mimicking neurogenesis during development. Human in vivo: 4 KB, 4 KS, 3 KC, 5 MB, 5 MF, 4 MS, 3 PB, 3 PL, 4 PS, 5 AB, 5 AS , 1 BR_N_PC Mouse in vivo: 4 KB, 4 KS, 3 KC, 5 MB, 5 MF, 4 MS, 3 PB, 3 PL, 4 PS, 5 AB, 5 AS , 3 BR, 3 PC_BRM, 1 BR_PCM

Gene expression profile of FOXM1 with Doxorubicin in MDA-MB-231 breast cancer cells

Project description:Transcription factors (TFs) play a crucial role in diverse cellular physiology by controlling down-stream target genes. It has been well recognized that TFs are attractive target for treating human cancer since transcriptional activity or gene expression level of TFs can be directly modulated. To explore which TF functions as survival factor in human breast cancer, we applied gene expression data sets for survival analysis. We identified that FOXM1 is a potent oncogenic survival factor out of eleven TFs. Loss of FOXM1 function leads to breast cancer cells more sensitized to Doxorubicin (Dox). To investigate how FOXM1 sensitizes cancer cell in the presence of Dox, we carried out gene expression array experiment to monitor how down-stream target genes are changed by FOXM1. MDA-MB-231 cells were incubated with siLuc or siFOXM1. Thirty six hours later, cells were incubated with Dox (5micro mol) for 36 hrs. 3 siLuc., 3 siFOXM1, 3 siLuc and Dox treatment, 3 siFOXM1 and Dox treatment

Regulation of gene expression by GLIPR1 in prostate cancer cells

Project description:Human glioma pathogenesis-related protein 1 (GLIPR1) and its mouse counterpart, Glipr1 are downregulated in prostate cancer (PCa) and other malignant cell lines, owing partly to methylation in the gene’s regulatory region. Loss of Glipr1 function predisposed mice to tumorigenesis. Restoration of GLIPR1 expression in prostate cancer cells and other malignant cells led to growth suppression and/or apoptosis. Here we show that restoring GLIPR1 expression in PCa cells leads to downregulated c-myc and cell cycle-related c-myc target genes, leading to the inhibition of cell cycle progression. DNA microarray (Illumina HumanHT-12) Prostate cancer cells were transduced with adenovirus-mediated GLIPR1 or control lacZ, grown in complete medium for 24 hours, synchronized by serum starvation for 24 hours, followed by serum restimulation for 30 min. RNA was prepared and subjected to DNA microarray analysis.

Characterization of gene expression profiles of gastric cancer in MD Anderson Cancer Center cohort

Project description:Clinical heterogeneity of gastric cancer reflected in unequal outcome of treatment is poorly defined in molecular level, and molecular subtypes and their associated biomarkers have not been established to improve prognostification and treatment of gastric cancer. Using microarray technologies, we analyzed gene expression profiling data from patients with advanced gastric cancer and uncovered potential prognostic subtypes and identify gene expression signature associated with prognosis.
