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)
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)
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)
OBJECTIVE To investigate the role of macrophage inflammatory protein (MIP)-3alpha in human ovulation. DESIGN Study of the levels of MIP-3alpha in serum and follicular fluid. The effects of interleukin (IL)-1alpha, IL-1 receptor antagonist (RA), and tumor necrosis factor (TNF)-alpha on the secretion of MIP-3alpha by primary cultured granulosa-lutein cells(More)
Polo-like kinase (PLK) is a cell cycle-regulated, cyclin-independent serine/threonine protein kinase. Recent reports have shown a critical role for PLK during tumorigenesis. To explore whether PLK plays a general role as a tumor marker of endometrial carcinomas, we examined the expression of PLK mRNA and protein in endometrial carcinomas and normal(More)
Survivin is a new member of the inhibitor of apoptosis family of anti-apoptotic proteins. It has been reported that survivin is expressed during fetal development and in cancer tissues. Because suppression of apoptosis is important for carcinogenesis and tumor growth, we investigated the expression of survivin in human endometrial carcinomas. We analyzed(More)
