Evidence for the presence of the stearyl-CoA desaturase system in the sarcoplasmic reticulum of rabbit slow muscle

Abstract

We have shown that the isolated sarcoplasmic reticulum from rabbit slow muscle contains cytochrome b5 which can be reduced via a flavoprotein, with FAD as the prosthetic group. In the presence of NADH and oxygen, these sarcoplasmic reticulum membranes can convert stearyl-CoA to oleyl-CoA, similarly to liver endoplasmic reticulum membranes. However, the stearyl-CoA desaturase system is virtually lacking in fast muscle sarcoplasmic reticulum. The data suggest that these differences between fast and slow twitch muscle may be related to the characteristic fatty acid composition of phospholipids and the function of the sarcoplasmic reticulum.

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. 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.
