Energy metabolism

Energy metabolism is the process of generating energy (ATP) from nutrients. Metabolism comprises a series of interconnected pathways that can function in the presence or absence of oxygen. Aerobic metabolism converts one glucose molecule into 30-32 ATP molecules. Fermentation or anaerobic metabolism is less efficient than aerobic metabolism.

    Strategies to restore levels of the enzyme cofactor nicotinamide adenine dinclueotide (NAD) late in life to maintain health by treatment with NAD precursors, such as nicotinamide mononucleotide (NMN), represent an exciting area of research in aging and age-related diseases. A study in Nature Metabolism provides an answer to the hotly debated yet fundamental question: how NMN actually gets into cells.

    The growth of new blood vessels (angiogenesis) is a bio-energetically demanding process. Surprisingly, the specific role of mitochondria in angiogenesis remains unclear. A study in this issue of Nature Metabolism now demonstrates that mitochondrial respiration is essential for angiogenic growth by controlling endothelial proliferation.

    Cell metabolism has long been at the forefront of tumour biology, but in the past decade the importance of cellular bioenergetics has been increasingly recognized in regulating immune cell function. Mechanistic studies in 2018 have highlighted cell metabolism as a potential therapeutic target for the treatment of rheumatoid arthritis.

    With many failures, a sense of helplessness has overshadowed the field of acute kidney injury (AKI). Publications in 2018 offer new hope: better drug targets, better end points and improved understanding of conditions that cause AKI and its complications bring promise that a drug will soon be available.
