Analysis of metabolic control in vivo using molecular genetics

Cell Biochemistry and Function
K M Brindle

Abstract

The aim of this brief review has been to illustrate the enormous power of molecular genetic techniques for testing out our, sometimes old, models of metabolic control. The technology allows us to ask some very simple but direct questions about the importance of specific enzymes in the control of flux. The answers, however, may not always be straightforward in that the absence of a change in pathway flux does not necessarily indicate that the enzyme is unimportant in flux control. Rather it would seem, from the relatively few studies that have been done, that the changes in the biological system which occur in response to a change in the concentration of a specific enzyme could tell us a lot about the role of that enzyme in metabolism and how it is controlled. I have restricted my discussion to studies in which relatively large numbers of cells have been modified genetically and subsequently characterized. This ignores a large and growing area in which micro-injection techniques are being used to introduce plasmid DNA or proteins into individual cells. The resultant phenotypes are then characterized at the single cell level using very sensitive optical techniques, such as fluorescence and bioluminescence. The reader is referred ...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.
