The effect of oophorectomy on the ribonucleic acid metabolism of a transplantable uterine tumour

The Biochemical Journal
W I Mainwaring, D C Williams

Abstract

1. The incorporation of [(14)C]phenylalanine and of [(3)H]uridine into the Guerin T8 uterine carcinoma has been examined. 2. The addition in vitro of polyuridylic acid caused an increase in the incorporation of labelled phenylalanine into tumour microsomes obtained from both oophorectomized and intact animals. 3. Oophorectomy of tumour-bearing animals decreased the specific activity due to the uptake in vivo of [(3)H]uridine into both the soluble and insoluble RNA of the tumour. 4. Actinomycin D caused a decrease in specific activity of RNA in the tumour in vivo, and puromycin inhibited uptake in vitro into tumour microsomes.

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.

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.
