Lipogenic activity of catfish liver. Lack of response to dietary changes and insulin administration

Comparative Biochemistry and Physiology. B, Comparative Biochemistry
A W Warman, N R Bottino


1. Some of the physical, chemical and kinetic properties of catfish liver lipogenic enzymes (acetyl-CoA carboxylase and fatty acid synthetase) were investigated. 2. The liver lipogenic enzymes of catfish exhibited maximal activity at 37 degrees C, even though these fish usually live at temperatures not above 24 degrees C. 3. The activity of the lipogenic enzymes of catfish liver was always low, regardless of the proportions of lipids or carbohydrates in the diet and could not be raised by insulin administration. 4. Under the conditions of the experiments, catfish liver fatty acid synthetase produced more stearate than palmitate and no myristate.

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.
