We studied the roles of the phosphatidylinositol 3-kinase (PI-3K)-Akt-BAD cascade, ERK-BAD cascade, and Akt-Raf-1 cascade in the paclitaxel-resistant SW626 human ovarian cancer cell line, which lacks functional p53. Treatment of SW626 cells with paclitaxel activates Akt and ERK with different time frames. Interference with the Akt cascade either by(More)
Regulation of the PI3K-protein kinase B/Akt (serine/threonine kinase) cascade by PRL-releasing peptide (PrRP) and insulin in GH3 rat pituitary tumor cells was investigated. PrRP and insulin rapidly and transiently stimulated the activation of Akt, and the PI3K inhibitor wortmannin blocked the PrRP- or insulin-induced activation of Akt. Both pertussis toxin(More)
Mouse beta-casein gene promoter contains a region termed block C which is crucial for its gene transcription induced by lactogenic hormones. Nuclear extracts from mouse mammary glands contain at least two binding complexes (DS1 and DS2) which specifically bind to double-stranded block C region DNA. The binding sequence of these complexes was identified to(More)
BACKGROUND It is important to predict the development of pre-eclampsia (PE) during early pregnancy to prevent its occurrence later on. In this study, we studied urinary biochemical parameters and blood pressure (BP) during and after pregnancy to find useful parameters for predicting PE. METHODS A case-control study was performed in 25 PE patients and 172(More)
The trophoblast, an important component of the mammalian placenta, has several essential biological roles in the maintenance of pregnancy. First, trophoblast cells must attach to the uterine endometrium, and then they must invade to a depth at which the vascular network exists. Here, we investigated the effects of epidermal growth factor (EGF) on alpha2(More)
 We report on a 13-year old girl with severe aplastic anemia and hypertrophic cranial pachymeningitis. She was admitted to our hospital with severe headache and vomiting. A computerized tomographic (CT) scan of the brain on the third day of symptoms showed a hyperdense area in the tentorial region. Magnetic resonance imaging (MRI) showed iso-intensity in(More)
For benign gynecological diseases, laparoscopic surgery has become a standard method. Its advantages include fast recovery, shorter hospital stay, decreased analgesic requirements, and lower perioperative complications. In recent years, laparoendoscopic single-site (LESS) surgery has become a new branch of surgery that increases cosmetic benefits over(More)
