Effects of maternal ethanol consumption on hepatic lipid biosynthesis in foetal and neonatal rats

The Biochemical Journal

Abstract

Effects of prolonged maternal ethanol consumption were studied on hepatic lipid content, on the rates of fatty acid synthesis and on the activities of enzymes involved in fatty acid synthesis in the livers of foetal and suckling neonatal rats. Prolonged maternal ethanol consumption resulted in a significant increase in the contents of hepatic total lipids, triacylglycerols and plasma unesterified fatty acids in foetal and neonatal rats. Studies in vitro with 3H2O showed that maternal ethanol consumption did not result in a significant change in its rate of incorporation into lipid fractions of foetal and neonatal livers. The rates of fatty acid synthesis showed a pronounced decrease immediately after birth, compared with the foetal stage, but increased in the adult animals. On the other hand, the highest rates of lipid oxidation were observed in the neonatal stage. Maternal ethanol consumption resulted in a significant decrease in the rates of [14C]palmitate oxidation to 14CO2 by both the foetal and neonatal livers. Maternal ethanol consumption did not result in an increase in the activities of any of the lipid-synthesizing enzymes tested throughout the period of development. Although increased fatty acid synthesis does not see...Continue Reading

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.
