Modulation of epidermal cell division and growth by oxygenation products of arachidonic acid. 1984

K Kragballe, and J J Voorhees

Recently accumulated data have shown that arachidonic acid derivatives play a role not only in cutaneous inflammation, but also in regulation of epidermal growth. Today, the best evidence for the involvement of leukotrienes in human skin disease is psoriasis. Such evidence includes: the presence of leukotrienes B4, C4, and D4 and monohydroxy-eicosatetraenoic acids in psoriatic skin lesions; the presence of these compounds in amounts capable of mediating epidermal proliferation, neutrophil accumulation, and vasodilatation characteristic of psoriasis; and improvement of psoriasis by 5-lipoxygenase inhibitors.

UI	MeSH Term	Description	Entries
D008084	Lipoxygenase	An enzyme of the oxidoreductase class primarily found in PLANTS. It catalyzes reactions between linoleate and other fatty acids and oxygen to form hydroperoxy-fatty acid derivatives.	Lipoxidase,Linoleate-Oxygen Oxidoreductase,Lipoxygenase-1,Lipoxygenase-2,Linoleate Oxygen Oxidoreductase,Lipoxygenase 1,Lipoxygenase 2,Oxidoreductase, Linoleate-Oxygen
D011565	Psoriasis	A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region. Accelerated epidermopoiesis is considered to be the fundamental pathologic feature in psoriasis.

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.

D001091	Arachidonate Lipoxygenases	Enzymes catalyzing the oxidation of arachidonic acid to hydroperoxyarachidonates. These products are then rapidly converted by a peroxidase to hydroxyeicosatetraenoic acids. The positional specificity of the enzyme reaction varies from tissue to tissue. The final lipoxygenase pathway leads to the leukotrienes. EC 1.13.11.- .	Arachidonic Acid Lipoxygenase,Lipoxygenase, Arachidonic Acid,Lipoxygenases, Arachidonate

D012867	Skin	The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
D016718	Arachidonic Acid	An unsaturated, essential fatty acid. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is formed by the synthesis from dietary linoleic acid and is a precursor in the biosynthesis of prostaglandins, thromboxanes, and leukotrienes.
