Ciliary beat frequency controlled by oestradiol and progesterone during ovarian cycle in guinea-pig Fallopian tube.

The ciliary beat frequency (CBF) of guinea-pig fimbria during the ovarian cycle was measured by video microscopy using a high-speed camera (500 Hz). In the follicular phase, with increasing concentrations of beta-oestradiol ([betaE(2)]) and a low concentration of progesterone ([PRG]), CBF increased from 13.5 to 16 Hz.

Transcriptional expression of survivin and its splice variants in endometriosis.

Survivin is a novel inhibitor of apoptosis (IAP), and the two splice variants of survivin (survivin-2B and survivin-EX3) have been identified. Gene expression levels of survivin, survivin-2B and survivin-EX3 in 56 ectopic (16 peritoneal red and 16 peritoneal black lesions and 24 ovarian endometriomata) and 13 eutopic endometrial tissues surgically obtained from 42 women with endometriosis (group A) were compared with those in 16 control eutopic endometrium from 16 women without endometriosis (group B) by quantitative RT-PCR analysis. Survivin mRNA expression levels in ectopic endometriotic tissues were significantly higher than those in eutopic endometrium of groups A and B over the whole cycle.

Tumor angiogenesis and molecular target therapy in ovarian carcinomas.

Growth of solid tumors depends on angiogenesis, the process by which new blood vessels develop from the endothelium of a pre-existing vasculature. Tumors promote angiogenesis by secreting various angiogeneic factors, and newly formed blood vessels induce tumor cell proliferation and invasiveness. Ovarian carcinomas have a poor prognosis, often associated with multifocal intraperitoneal dissemination accompanied by intense neovascularization.

Expression of apoptosis-related proteins in adenomyotic uteri treated with danazol and GnRH agonists.

The biologic properties of adenomyosis and the effects of therapeutic agents on adenomyosis were evaluated with immunohistochemistry, terminal deoxy-nucleotidyl transferase-mediated dUTP-biotin nick end-labeling (TUNEL) method, transmission electron microscopy, and analysis of genomic abnormality. In the adenomyotic endometrium, estrogen receptor (ER) expression was more intense than in the eutopic endometrium during the secretory phase, and bcl-2 was constantly expressed throughout the menstrual cycle. The expression of ER and bcl-2 was weaker in the adenomyotic endometrium treated with danazol than in that treated with gonadotro-pin-releasing hormone agonist (GnRHa), whereas bcl-2 phosphorylated on serine-87 was more intensely expressed in danazol-treated adenomyotic endometrium than in the GnRHa-treated one.

Glutathione S-transferase GSTM1, GSTT1 and p53 codon 72 polymorphisms in human tumor cells.

The genes of the glutathione S-transferase (GST) family encode enzymes that appear to be critical in cellular protection against the cytotoxic effects, whereas p53 is a tumor suppressor gene. Despite a large number of studies on germline polymorphisms of GSTM1, GSTT1 and p53 genes, there have been very few reports on genotyping of these genes in human malignant tumor cells. In this study, we investigated GSTM1, GSTT1 and p53 codon 72 polymorphisms in a variety of human tumor cell lines originating from different organs to clarify tissue-specific polymorphic frequency of these genes in human solid tumors.

Effects of Unkei-to on FSH, LH and estradiol in anovulatory young women with hyper- or hypo-functioning conditions.
