Configurational changes of mitochondria and mitochondrial nucleoids (mt-nucleoids) during meiosis and sporulation in the yeast, Saccharomyces cerevisiae, were examined using the mitochondrial membrane-binding fluorescent dye, dimethyl aminostyrylmethylpyridiniumiodine (DASPMI) and the DNA-binding fluorescent dye, 4',6-diamidino-2-phenylindole (DAPI). In(More)
In order to evaluate the involvement of cell proliferation and apoptosis in the pathogenesis of endometriosis, we investigated the effects of interferon-gamma (IFN-gamma) on cell growth inhibition and apoptosis of cultured ovarian endometriotic cyst stromal cells (ECSC), eutopic endometrial stromal cells with endometriosis (ESCwE) and normal endometrial(More)
It has been demonstrated that human endometrial stromal cells (ESC) produce a variety of chemokines in vivo and in vitro. To evaluate the expression of epithelial neutrophil-activating peptide 78 (ENA-78) in the endometrium, concentrations of ENA-78 in cyclic endometrial tissues were measured using enzyme-linked immunosorbent assay. The expression of ENA-78(More)
PURPOSE HDAC inhibitors (HDACIs) have been shown to inhibit cancer cell proliferation, stimulate apoptosis, and induce cell cycle arrest. Our purpose was to investigate the antiproliferative effects of the HDACIs [suberoyl anilide bishydroxamine, valproic acid (VPA), trichostatin A, and sodium butyrate] against six endometrial cancer cell lines.

BACKGROUND Human epidermal growth factor receptor 2 (HER2) is overexpressed in 25-30% of ovarian carcinoma cases and a correlation between increased HER2 expression and decreased survival has been demonstrated. HER2 is a ligand-less member of the HER family that functions as the preferred coreceptor for epidermal growth factor receptor (EGFR), HER3, and(More)
To evaluate the involvement of chemokines in the pathogenesis of endometriosis, we investigated the expression of CXC chemokines in cultured ovarian endometriotic cyst stromal cells (ECSC), endometrial stromal cells with endometriosis (ESCwE), and normal endometrial stromal cells (NESC). Using ELISA, TNF-alpha significantly enhanced the production of IL-8,(More)
Mitochondrial nucleoids (mt-nucleoids) of the yeast, Saccharomyces cerevisiae, were isolated from spheroplasts of stationary phase cells and their structure and organization were investigated by fluorescence microscopy, electron microscopy, and biochemical techniques. Isolated mt-nucleoids were spherical or ovoid and 0.3-0.6 micron in diameter, and were(More)
Basic helix-loop-helix (bHLH) DNA-binding proteins have been reported to regulate tissue-specific transcription of cellular differentiation within multiple cell lineages. The Id family of helix-loop-helix proteins does not possess a basic DNA-binding domain and functions as a negative regulator of bHLH proteins by forming high-affinity heterodimers with(More)
BACKGROUND Histone deacetylase inhibitors (HDACIs) can inhibit proliferation, stimulate apoptosis, and induce cell cycle arrest in malignant cells. METHODS The authors investigated the effects of four HDACIs on nine ovarian carcinoma cell lines in vitro and in vivo. Ovarian carcinoma cells were treated with a variety of HDACIs, and their effects on cell(More)
To evaluate the involvement of platelet-derived growth factor (PDGF) isoforms (PDGF-AlphaAlpha, PDGF-AB, and PDGF-BB) on endometrial tissue remodeling during the perimenstrual period, we investigated the effects of PDGF on the proliferation, motility, invasiveness, and contractility of cultured human endometrial stromal cells (ESC) using a modified(More)
