Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Cdca7l acts as a male-specific oncogene in astrocytoma and glioblastoma, and can transform primary astrocyte growth in soft agar. We stably overexpressed Cdca7l in mouse primary astrocytes and compared gene expression to primary astrocytes expressing empty vector control in male and female cell to identify gene expression differences between male and female cells and between Cdca7l-overexpressing and normal primary astrocytes.

Description
Cdca7l is expressed higher in male astrocytoma/GBM than female tumors or normal cells, and knockdown of Cdca7l blocks growth of male tumor cells, but not female tumor cells. We stably depleted Cdca7l in mouse astrocytoma cells and compared gene expression to control astrocytoma cells expressing non-targeting scrambled shRNA in male and female cells and to wild type primary astrocytes to identify gene expression differences between male and female cells and between Cdca7l-depleted, scrambled shRNA control cells and wild type primary astrocytes.

Description
CDCA7L is expressed higher in male astrocytoma/GBM than female tumors or normal cells, and knockdown of CDCA7L blocks growth of male tumor cells, but not female tumor cells. We stably depleted CDCA7L in human GBM cells and compared gene expression to control GBM cells expressing non-trageting scrambled shRNA in male and female cells to identify gene expression differences between male and female cells and between CDCA7L-depleted and scrambled shRNA control cells.

Description
Poorly differentiated type synovial sarcoma (PDSS) is a variant of synovial sarcoma characterized by predominantly round or short-spindled cells. Although accumulating evidence from clinicopathological studies suggests a strong association between this variant of synovial sarcoma and poor prognosis, little has been reported on the molecular basis of PDSS. To gain insight into the mechanism(s) that underlie the emergence of PDSS, we analyzed the gene expression profiles of 34 synovial sarcoma clinical samples, including 5 cases of PDSS, using an oligonucleotide microarray. In an unsupervised analysis, the 34 samples fell into 3 groups that correlated highly with histological subtype, namely, monophasic, biphasic, and poorly differentiated types. PDSS was characterized by down-regulation of genes associated with neuronal and skeletal development and cell adhesion, and up-regulation of genes on a specific chromosomal locus, 8q21.11. This locus-specific transcriptional activation in PDSS was confirmed by reverse transcriptase (RT)-PCR analysis of 9 additional synovial sarcoma samples. Our results indicate that PDSS tumors constitute a distinct genetic group based on expression profiles.

Description
Aberrant DNA methylation is induced at specific promoter CpG islands (CGIs) in contrast with mutations. The specificity is influenced by genome architecture and epigenetic factors, but their relationship is still unknown. In this study, we isolated promoter CGIs susceptible and resistant to aberrant methylation induction during prostate and breast carcinogenesis. The effect of genome architecture was more evident for promoter CGIs susceptible in both of the two tissues than for promoter CGIs susceptible only in one tissue. Multivariate analysis of promoter CGIs with tissue-nonspecific susceptibility showed that genome architecture, namely a remote location from SINE (OR=5.98; 95% CI=2.33-15.34) and from LINE (OR=2.08; 95% CI=1.03-4.21), was associated with increased susceptibility, independent of epigenetic factors such as the presence of RNA polymerase II (OR=0.09; 95% CI=0.02-0.48) and H3K27me3 (OR=3.28; 95% CI=1.17-9.21). These results showed that methylation susceptibility of promoter CGIs is determined both by genome architecture and epigenetic factors, independently.
