Triacylglycerol secretion and fatty acid synthesis by the liver in acute uremic rats

Experimental Pathology
M Hohenegger, H Schuh

Abstract

In bilaterally nephrectomized rats fatty acid synthesis (incorporation of 3H from 3H2O into fatty acids by the liver) and triacylglycerol (TG) secretion by the liver (Triton method) were investigated 24 h after surgery. Starved and fed rats were employed. In uremic rats fatty acid synthesis occurs at a normal rate; prevention of acidosis during uremia by bicarbonate treatment has no influence on lipid synthesis. Following intravenous injections of Triton WR 1339 the TG plasma levels are considerably lower in uremic rats than in corresponding controls. As the plasma volume is significantly higher in uremic animals, there is only an insignificant decrease in the absolute TG secretion rate in these animals. The removal of TG from the blood to the tissues in severely reduced in uremia with acidosis. The normal rates of fatty acid synthesis and nearly normal rates of TG secretion may, therefore, be considered as permissive factors for the development of uremic hypertriglyceridemia. The lesser degree of hypertriglyceridemia in uremia without acidosis is only caused by the better removal of TG from the blood (as could be demonstrated earlier). Fatty acid synthesis and TG secretion do not play any role in this case.

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

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.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. 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.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
