Modulation of steroid production in goat ovarian cells: effect of progestins and antiprogestins

Abstract

Effect of various synthetic progestins and antiprogestational compounds on progesterone (P) and estradiol (E) production by isolated goat ovarian granulosa (G) and corpus luteum (CL) cell types was studied in vitro. Steroid production was studied either under basal conditions or after stimulation with follicle stimulating hormone (FSH) in the presence of aromatase substrate, androstenedione (A). None of the progestins had any significant effect on basal P and E production by either cell types during 48 hour of culture. The FSH and A - induced increase in P and E production was significantly inhibited following concommitant treatment with synthetic progestins at concentrations higher than 10(-7) M. The added progestins had no effect on G and CL cell viability. None of the antiprogestational compounds had any significant effect on basal steroid production in either of the cell types. Furthermore, the higher concentrations of three antiprogestins namely RMI 14156, STS 557 and isomer 201 of RMI 12936, were found to stimulate significantly the basal as well as FSH + A - induced production of estradiol in both the cell types. In contrast, the other two antiprogestins tested were found to stimulate the gonadotropin + A - induced produ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
