Oxidative stress and the ovary
Autor: H R, Behrman, P H, Kodaman, S L, Preston, S, Gao
Publikováno v: Journal of the Society for Gynecologic Investigation. 8(1 Suppl)
Superoxide (O(2)(-)), hydrogen peroxide (H(2)O(2)), and lipid peroxides are generated in luteal tissue during natural and prostaglandin-induced regression in the rat, and this response is associated with reversible depletion of ascorbic acid. Reactiv

Utility of commonly used commercial human chorionic gonadotropin immunoassays in the diagnosis and management of trophoblastic diseases
Autor: L A, Cole, S, Shahabi, S A, Butler, H, Mitchell, E S, Newlands, H R, Behrman, H L, Verrill
Publikováno v: Clinical chemistry. 47(2)
Patients with trophoblastic diseases produce ordinary and irregular forms of human chorionic gonadotropin (hCG; e.g., nicked hCG, hCG missing the beta-subunit C-terminal segment, hyperglycosylated hCG, and free beta subunit) that are recognized to di

Endocrine-regulated and protein kinase C-dependent generation of superoxide by rat preovulatory follicles
Autor: P H, Kodaman, H R, Behrman
Publikováno v: Endocrinology. 142(2)
The ovulatory LH surge results in follicular inflammation with an increase in cytokines and PGs. Reactive oxygen species (ROS) are also produced during inflammatory processes. To study ROS generation during the ovulatory cascade, preovulatory follicl

Proliferation and differentiation of rat theca-interstitial cells: comparison of effects induced by platelet-derived growth factor and insulin-like growth factor-I
Autor: A J, Duleba, R Z, Spaczynski, A, Arici, R, Carbone, H R, Behrman
Publikováno v: Biology of reproduction. 60(3)
This study was designed to evaluate mechanisms regulating proliferation of steroidogenically active and steroidogenically inactive theca-interstitial (T-I) cells, and, specifically, to evaluate the effects of platelet-derived growth factor (PDGF) and

Prostaglandin f2alpha treatment in vivo, but not in vitro, stimulates protein kinase C-activated superoxide production by nonsteroidogenic cells of the rat corpus luteum
Autor: R F, Aten, T R, Kolodecik, M J, Rossi, C, Debusscher, H R, Behrman
Publikováno v: Biology of reproduction. 59(5)
Luteal regression is associated with the generation of reactive oxygen species (ROS). To determine the nature of the ROS generator, cells isolated from luteinized rat ovaries were examined for ROS production using luminol-amplified chemiluminescence

Apoptosis and PCNA expression induced by prolactin in structural involution of the rat corpus luteum
Autor: T. Goto, E. Ito, R. Kudo, T. Endo, H. R. Behrman, T. Kiya, H. Yamamoto
Publikováno v: Journal of endocrinological investigation. 21(5)
There are two stages of luteal regression. The first stage is functional regression that is characterized by a decreased production of progesterone secretion; the second stage of structural involution is referred to as a structural luteolysis. In rod

Accumulation of ascorbate by endocrine-regulated and glucose-sensitive transport of dehydroascorbic acid in luteinized rat ovarian cells
Autor: P H, Kodaman, R F, Aten, H R, Behrman
Publikováno v: Biology of reproduction. 58(2)
The corpus luteum is notable for very high levels of ascorbic acid. In luteal cells, ascorbic acid depletion occurs as a result of consumption during radical scavenging, inhibition of ascorbic acid uptake, and stimulation of its secretion. Oxidation

Endocrine regulation of ascorbic acid transport and secretion in luteal cells
Autor: B, Musicki, P H, Kodaman, R F, Aten, H R, Behrman
Publikováno v: Biology of reproduction. 54(2)
Luteal ascorbic acid depletion by LH and prostaglandin (PG) F2 alpha is well known, but how such depletion occurs is not. We therefore investigated the nature and regulation of ascorbic acid uptake and depletion in the rat CL and luteal cells. In viv

Immunosuppressive levels of glucocorticoid block extrauterine luteolysins in the rat
Autor: F, Wang, J C, Riley, H R, Behrman
Publikováno v: Biology of reproduction. 49(1)
Leukocytes, normal constituents of the corpus luteum, release prostaglandins (PGs), superoxide, and hydrogen peroxide (H2O2) upon activation. These products appear to mediate luteolysis, and it has been postulated that activated leukocytes serve a ro
