Description
Profiles of genome-wide DNA methylation were investigated in leiomyomas and in myometrium with and without leiomyomas. Profiles of DNA methylation in the myometrium with and without leiomyomas were quite similar while those in leiomyomas were distinct.

Description
Transcriptome profiles were investigated in isolated endometrial stromal cells (ESCs) from eutopic and ectopic endometrium. The profiles were quite different between eutopic ESC and ectopic ESC, whereas no clear dfference was recognized between eutopic ESC with and without endometriosis.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Transcription factor access to regulatory elements is prevented by the nucleosome. Heat shock factor 1 (HSF1) is a winged helix transcription factor that plays roles in control and stressed conditions by gaining access to target elements, but mechanisms of HSF1 access have not been well known in mammalian cells. We show a physical interaction between the wing motif of human HSF1 and replication protein A (RPA), which is involved in DNA metabolism. Depletion of RPA1 abolishes HSF1 access to the promoter of HSP70 in unstressed conditions, and delays its rapid activation in response to heat shock. The HSF1-RPA complex leads preloading of RNA polymerase II and opens chromatin structure by recruiting a histone chaperone FACT. Furthermore, this interaction is required for melanoma cell proliferation. These results provide a mechanistic basis for constitutive HSF1 access to nucleosomal DNA, which is important for both basal and inducible gene expression.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
To clarify inflammatory genes whose expression is suppressed at high temperatures, we performed comprehensive analysis of gene expression by using a DNA microarray. Two independent primary cultures of mouse embryo fibroblasts (MEF1 and MEF2) were treated with LPS for 4 hours, or treated with LPS for 4 hours after the pretreatment with heat shock at 42C for 1 hour, and we identified 100 genes that undergo more than a 3-fold increase with LPS treatment. Remarkably, 86 genes (86%) underwent less than a 2-fold increase after combined treatments with heat shock and LPS in MEF1 and MEF2 cells.
Publication Title
Heat shock transcription factor 1 inhibits expression of IL-6 through activating transcription factor 3.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
To analyze target genes of human heat shock transcription factor 1 (HSF1), we first generated two independent HeLa clones (RDT1 and RDT2) expressing an actively mutated hHSF1 (hHSF1RDT), which lacks the regulatory domain that masks its activation domain and possesses a glutamic acid at amino acid 395 instead of a leucine in the suppression domain of the trimerization domain (Fujimoto et al., J. Biol. Chem. 280, 34908-34916, 2005). We also generated a HeLa clone expressing chicken HSF1 (HeLa/cHSF1) to compare its profile of gene expression with those of RDT1 and RDT2 cells (Nakai and Morimoto, Mol. Cell. Biol. 13, 1983-1997, 1993). We then carried out DNA microarray analysis using total RNA isolated from HeLa, HeLa/cHSF1, RDT1, and RDT2 cells grown under normal growth conditions.
Publication Title
