Determination of hydroxyoctadecadienoic acids.

Free and esterified 13(R,S)-hydroxyoctadecadienoic acids: principal oxygenase products in psoriatic skin scales.

Characterization of the chemical form and stereo-specificity of the fatty acid derivatives of arachidonic and linoleic acid in psoriatic epidermis is needed to define the enzymatic origin of these compounds and their possible role in pathogenesis. In an analysis of psoriatic skin scales, both free and esterified 13-hydroxyoctadecadienoic acids were the principal fatty acid derivatives, present ...

Apoptosis Induced by 13-S-hydroxyoctadecadienoic acid in the Breast Cancer Cell Lines, MCF-7 and MDA-MB-231

jun-B Messenger RNA and Inhibition of DNA Synthesis by Prostaglandin E2 in Syrian Hamster Embryo Cells

Fatty acid metabolites such as prostaglandins are important regulators of DNA synthesis and cell proliferation. However, the mechanisms involved in this regulation are unclear. We have examined the effects of several fatty acid metabolites on the expression of the growth-related genes c-jun and jun-B in Syrian hamster embryo cells. Treatment of cells with prostaglandin E2 (PGE2) resulted in the...

Stereospecificity of the products of the fatty acid oxygenases derived from psoriatic scales.

The principal in vivo oxygenase products of arachidonic acid and linoleic acid in psoriatic skin scales are 12-hydroxyeicosatetraenoic acid (R/S ratio = 5.7), 13-hydroxyoctadecadienoic acid (S/R = 1.9), and 9-hydroxyoctadecadienoic acid (R/S = 2.4). Definition of the enzymatic origin of these fatty acid derivatives is an important step in assessing their possible role in the pathogenesis of pso...
