In vitro synthesis of rat testicular androgen-binding protein (ABP)

Molecular and Cellular Endocrinology
E M RitzénV Hansson


Testicular tissue from immature and adult rats shows in vitro synthesis of androgen-binding protein (ABP). The ABP synthesis is dependent on a complete tissue culture medium, the incubation temperature and the age of the rats. ABP synthesis is inhibited at 0 degrees C or in the presence of cycloheximide, puromycin or sodium fluoride. Immature (17-25-day-old rat) testes showed a higher rate of ABP synthesis per 100 mg tissue than adult rat testes during 'baseline' conditions (no additions to the medium). Addition of NIH-FSH-S10 or testosterone to the medium increases the production of ABP by the testicular minces. The in vitro techniques have proved to be useful for studies of direct hormonal influence on the Sertoli cell protein synthesis.

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

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.
