Gene expression profiling of LCM captured breast cancer cells

Project description:The purpose of this study is to obtain comprehensive gene expression profiles in breast cancer. Mammary gland cells were specifically isolated from 433 clinical tissue samples by laser capture microdissection (LCM). Total RNAs were extracted from LCM captured samples. We investigated gene expression profiles in 417 patients with breast cancer and 16 non-tumor tissues as a normal control using an Affymetrix GeneChip. Mammary gland cells were captured from clinical tissues of breast cancer patient by LCM. Gene expression profilings for 417 tumor and 16 non-tumor samples were acquired using GeneChip Human Genome U133 Plus 2.0 (Affymetrix, Santa Clara, CA). Microarray datasets were normalized and transformed to log2 values using robust multi-array average (RMA) method with R statistical software and BioConductor package.

Homo sapiens MSCs: Normoxia vs. Hypoxia

Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.

Homo sapiens immortalized MSCs: KP vs. 3A6

Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.

Gene expression anlaysis of laser-capture microdissected tumor and stroma from triple negative breast cancer

Project description:LCM was perfomed on adjacent tumor and stromal cells to identify differentially expressed genes in triple negative breast cancer. To determine differences in tumor and adjacent stromal tissue, laser-capture microdissction was perfomed on 10 triple negative breast cancer specimans to isolate tumor and stromal cells for gene expression analysis. RNA was isolated from captured cells and hybridized to affymetrix gene expression microarrays.
