Prostaglandin production by isolated cells of rat uterus incubated with or without progesterone

Prostaglandins, Leukotrienes, and Essential Fatty Acids
P V Peplow, P R Hurst

Abstract

The production of prostaglandins F2 alpha and 6-keto F1 alpha in vitro by the luminal epithelial and the residual (mainly stomal) cells isolated from the uteri of proestrous rats have been measured. The basic procedure involved culturing the cells overnight, washing, and then incubating for 2 h when the amounts of prostaglandins released into the medium were determined by radioimmunoassay. No significant change occurred when the epithelial cells were incubated in the combined presence of arachidonic acid and progesterone for the short-term culture compared to being incubated with arachidonic acid alone. However, when progesterone was incorporated into the medium for the overnight culture, a significant increase occurred in 6-keto PGF1 alpha production by the epithelial cells, without any change in PGF2 alpha, compared to when the cells were incubated overnight in the absence of progesterone. It is suggested that overnight treatment of the epithelial cells with progesterone increases the amount or activity of prostacyclin synthetase, responsible for converting PGH2 endoperoxide to PGI2. Very low levels of prostaglandin production were found for the residual cells.

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.
