Recent developments in peroxisome biology. 1996

C Masters, and D Crane

Peroxisomes are subcellular organelles that are present in all eukaryotic organisms. These organelles are the focus of much contemporary interest among cellular and medical biologists--an interest which coincides with the realization of their vital role in higher organisms, their unique metabolic and biogenetic characteristics, and their widespread involvement in genetic and degenerative disease. This article reviews some of the major recent developments in peroxisome biology.

UI	MeSH Term	Description	Entries
D008830	Microbodies	Electron-dense cytoplasmic particles bounded by a single membrane, such as PEROXISOMES; GLYOXYSOMES; and glycosomes.	Glycosomes,Glycosome,Microbody
D010084	Oxidation-Reduction	A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).	Redox,Oxidation Reduction
D005609	Free Radicals	Highly reactive molecules with an unsatisfied electron valence pair. Free radicals are produced in both normal and pathological processes. Free radicals include reactive oxygen and nitrogen species (RONS). They are proven or suspected agents of tissue damage in a wide variety of circumstances including radiation, damage from environment chemicals, and aging. Natural and pharmacological prevention of free radical damage is being actively investigated.	Free Radical
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D001695	Biology	One of the BIOLOGICAL SCIENCE DISCIPLINES concerned with the origin, structure, development, growth, function, genetics, and reproduction of animals, plants, and microorganisms.
D017382	Reactive Oxygen Species	Molecules or ions formed by the incomplete one-electron reduction of oxygen. These reactive oxygen intermediates include SINGLET OXYGEN; SUPEROXIDES; PEROXIDES; HYDROXYL RADICAL; and HYPOCHLOROUS ACID. They contribute to the microbicidal activity of PHAGOCYTES, regulation of SIGNAL TRANSDUCTION and GENE EXPRESSION, and the oxidative damage to NUCLEIC ACIDS; PROTEINS; and LIPIDS.

D030342	Genetic Diseases, Inborn	Diseases that are caused by genetic mutations present during embryo or fetal development, although they may be observed later in life. The mutations may be inherited from a parent's genome or they may be acquired in utero.	Hereditary Diseases,Genetic Diseases,Genetic Disorders,Hereditary Disease,Inborn Genetic Diseases,Single-Gene Defects,Defect, Single-Gene,Defects, Single-Gene,Disease, Genetic,Disease, Hereditary,Disease, Inborn Genetic,Diseases, Genetic,Diseases, Hereditary,Diseases, Inborn Genetic,Disorder, Genetic,Disorders, Genetic,Genetic Disease,Genetic Disease, Inborn,Genetic Disorder,Inborn Genetic Disease,Single Gene Defects,Single-Gene Defect
