We observed that serum contains a factor(s) that inhibits the induction of peroxisome proliferator-activated receptor-gamma (PPARgamma) by 15-deoxy-Delta(12,14)-PGJ(2) (15dJ(2)). Ten percent FBS reduces 15dJ(2) induction of PPARgamma from over 150-fold to less than 15-fold in EP-JEG cells, a stably
OBJECTIVE
Immunosuppressive factor(s) of trophoblast origin may contribute to the immunological privilege afforded the fetal allograft. Characterization of these immunoregulators in humans has been impeded by a lack of sufficient quantities of early gestational trophoblast for
Human serum pregnancy-specific beta1-globulin (beta1-GP) was localized in paraffin sections of placenta and chorioepithelioma of the uterus by indirect immunofluorescence. The structures containing beta1-GP but not human serum albumin were regarded as specifically associated with beta1-GP
A 15-year-old girl developed severe hyperthyroidism secondary to metastatic choriocarcinoma. Her serum contained high levels of human chorionic gonadotropin (HCG) by radioimmunoassay and had a thyroid-stimulating activity different from that of pituitary thyrotropin (TSH) or of long-acting thyroid
A cloned cell line of human choriocarcinoma was evaluated as a model of human placental oestrogen production. Oestrone formation from dehydroepiandrosterone (D), D-sulphate (DS) or 4-androstenedione (A) was less than or equal to 5% of oestradiol-17beta (Oe2) formation. Oe2 formation from D and A was
OBJECTIVE
The benefit of polyvalent immunoglobulins (IVIG) for patients with recurrent pregnancy loss (RPL) is controversially discussed. Anti-trophoblast antibodies as an expression of immune pathology have been associated with RPL. We investigated whether the antibody activity against the
Placental transport of long chain polyunsaturated fatty acids is important for fetal growth and development. In order to examine the effects of leptin and insulin on fatty acid uptake by the placenta, placental choriocarcinoma (BeWo) cells were used. BeWo cells were incubated for 5h at 37 degrees C
Luteinizing hormone-releasing factor (LRF)-like immunoreactivity was demonstrated by a three layer bridge immunoperoxidase technique in the syncytiotrophoblast of early human placenta, hydatidiform mole and choriocarcinoma. Anti-LRF antiserum was prepared by immunizing rabbits with synthetic LRF
The process of embryo implantation and trophoblast invasion is considered the most limiting factor in the establishment of pregnancy. Leptin was originally described as an adipocyte-derived signaling molecule for the central control of metabolism. However, it has been suggested that leptin is
Interactions of three Ru(II) chlorophenyl terpyridine complexes: [Ru(Cl-Ph-tpy)(en)Cl]Cl (1), [Ru(Cl-Ph-tpy)(dach)Cl]Cl (2) and [Ru(Cl-Ph-tpy)(bpy)Cl]Cl (3) (Cl-Ph-tpy = 4'-(4-chlorophenyl)-2,2':6',2''-terpyridine, en = 1,2-diaminoethane, dach = 1,2-diaminocyclohexane, bpy = 2,2'-bipyridine) with
An implnated choriocarcinoma growing inthe brains of monkeys was used as a brain-tumor model for the study of the cerebral distribution of two commonly used physiological markers, inulin and albumin; tissue samples were obtained from the tumor, adjacent brain, and distant brain. An extravascular
We report an unusual hepatoid adenocarcinoma in Barrett's esophagus with achalasia, which developed in a 44-year-old Japanese woman. The patient received an esophago-gastrectomy after diagnosis of the tumor and achalasia at the lower esophagus, 4 months before her death due to multiple metastatic
OBJECTIVE
We examined the effect of sildenafil citrate on advanced glycation end products (AGEs)-induced soluble fms-like tyrosine kinase 1 (sFlt-1) release in JEG-3 choriocarcinoma cells.
METHODS
Cells were incubated with control bovine serum albumin (BSA) or AGEs-BSA, and expression of sFlt-1 mRNA
Aminoglycosides (AG) are known to readily cross the placenta, although the mechanisms responsible for placental transport have not been characterized. Megalin is expressed in human placenta, and it is reasonable to speculate, given its role in renal AG uptake, that it is similarly involved in
Prolactin (PRL) and other lactogenic hormones feed back at the hypothalamus to inhibit PRL release. At midpregnancy, high circulating levels of placental lactogens (PL) terminate the mating-induced biphasic PRL surges in female rats. In the dark period preceding parturition, however, an ante-partum
