Effects of adrenal steroid hormones on mitochondrial maturation during the late fetal period

Abstract

In the present work, we described the perinatal changes in mitochondrial maturation that contribute to metabolic development in the rat kidney. We focused on cytochrome-c oxidase activity and gene expression from the last three days of gestation to one day after birth. The role of adrenal steroids in the development of cytochrome-c oxidase expression and of mitochondrial DNA content was also investigated by studying the effects of fetal adrenalectomy. During the perinatal period, the developmental pattern of the cytochrome-c oxidase enzymatic complex exhibited parallel increases in transcript levels, protein content and enzyme activity, suggesting a transcriptional regulation of this enzyme. Adrenalectomy led to a decrease in fetal kidney cytochrome-c oxidase messengers and mtDNA content while administration of dexamethasone restored normal levels. In contrast, mtDNA content was unchanged in liver and heart after adrenalectomy whereas levels of cytochrome-c oxidase transcripts were controlled by adrenal steroids in liver but not in heart. These results indicate that adrenal steroid hormones contribute to the regulation of perinatal maturation of mitochondria in rat kidney and that these hormones are involved in the fetal mitoch...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.
