In vitro 16 alpha-hydroxylation of progesterone by testes of crab-eating monkey (Macaca irus): a characteristic of primates?

Comparative Biochemistry and Physiology. B, Comparative Biochemistry

Radioactive 16 alpha-hydroxyprogesterone was obtained as one of the major metabolites of [14C]pregnenolone and progesterone by testicular homogenates of an adult crab-eating monkey (Macaca irus). 16 alpha-hydroxylation of progesterone occurred by incubation of testes of men and and the monkey, but not by those of rodents and other vertebrates examined.

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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
