Nucleosome Remodeling

2020
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure. Nucleosome remodeling complex Eukaryotic cells have specialized enzymes called ATP-dependent nucleosome remodeling enzymes. These enzymes...

Zebrafish represent a powerful vertebrate model that has been under-utilised for metabolic studies. Here we describe a rapid way to measure the in vivo metabolic profile of developing zebrafish that allows the comparison of different mitochondrial function parameters between genetically or pharmacologically manipulated embryos, thereby increasing the applicability of this organism.

What is Metabolism?

2019
Overview Metabolism represents all of the chemical activity in a cell, including reactions that build molecules (anabolism) and those that break molecules down (catabolism). Anabolic reactions require energy, whereas catabolic reactions provide it. Thus, metabolism describes how cells transform energy through a variety of chemical reactions, which are often made more efficient with the help of enzymes.

In cells, critical molecules are either built by joining together individual units like amino acids or nucleotides, or broken down into smaller components. Respectively, the reactions responsible for this are referred to as anabolic and catabolic. These reactions require or produce energy typically in the form of a “high-energy” molecule called ATP. Together, these processes make up “Cell Metabolism,” and are hallmarks of healthy, living cells.JoVE’s introduction to cell metabolism briefly...

Metabolic Labeling

2023
Metabolic labeling is used to probe the biochemical transformations and modifications that occur in a cell. This is accomplished by using chemical analogs that mimic the structure of natural biomolecules. Cells utilize analogs in their endogenous biochemical processes, producing compounds that are labeled. The label allows for the incorporation of detection and affinity tags, which can then be used to elucidate metabolic pathways using other biochemical analytical techniques, such as SDS-PAGE...
FAQs
Mitochondrial function is one of the central features that can change during metabolic remodeling. Altered mitochondrial activity may influence how neural cells generate ATP, manage nutrient-derived energy, and maintain redox balance, which refers to the relationship between oxidation and reduction reactions. These changes help connect cellular metabolism with demanding processes such as synaptic transmission, development, and repair.
Neural cells do not direct all available substrates toward ATP production. Metabolic remodeling can redistribute substrates among energy generation, biosynthesis, and signaling. This allocation allows metabolism to support immediate energetic requirements while also supplying materials for cellular activity and longer-term changes. Examining these competing uses helps researchers determine how energy status is linked to neural function.
Changes in cellular activity, the surrounding environment, or physiological demand can shift metabolic organization. In nervous system cells, those shifts may involve glucose and lipid metabolism, mitochondrial function, or redox balance. Studying the response to these conditions helps reveal how neurons and glial cells adjust energy-related processes when functional requirements change.
Metabolic remodeling can influence neurons and glial cells by changing how each cell type handles energy production, nutrient use, mitochondrial activity, and redox balance. Because both cell types participate in nervous system function, altered metabolism may affect the cellular support needed for synaptic transmission, development, or repair. Comparing these responses can clarify how neural circuits adapt.
A useful investigation can track several connected features rather than focusing on energy production alone. Relevant areas include glucose metabolism, lipid metabolism, mitochondrial function, redox balance, and how substrates are allocated to ATP production, biosynthesis, or signaling. Considering these dimensions together helps researchers characterize the nature of a metabolic change and its possible neural relevance.
Synaptic transmission, development, and repair place changing demands on nervous system cells. Metabolic remodeling provides a framework for examining whether energy production and nutrient use are adjusted to meet those demands. Linking metabolic changes with these neural processes can help explain how circuits adapt and how cellular energy organization may support recovery after physiological or damaging events.
Neuroscience studies use metabolic remodeling to investigate how altered energy production, nutrient use, mitochondrial function, or redox balance may relate to neurological disorders. This perspective is relevant to research on neurodegeneration and brain injury because disrupted metabolism may accompany impaired neural function. The findings can also inform investigations of potential interventions that target cellular metabolism.
Patterns of metabolic remodeling can show how nervous system cells reorganize energy-related processes as functional requirements change. When these patterns are considered alongside synaptic transmission, development, or repair, they provide insight into the cellular basis of neural circuit adaptation. Conversely, disrupted patterns may help researchers examine why metabolic imbalance is associated with neurological disease or injury.
