Arachidonic acid (AA) is converted by enzymes in an important metabolic pathway to produce molecules known collectively as eicosanoids, 20 carbon molecules with significant physiological and pathological functions in the human body. Cyclooxygenase (COX) enzymes work in one arm of the pathway to produce prostaglandins (PGs) and thromboxanes (TXs), while the actions of 5-lipoxygenase (ALOX5 or 5LO) and its associated protein (ALOX5AP or FLAP) work in the other arm of themetabolic pathway to produce leukotrienes (LTs). The expression of the COX and ALOX5 enzymes that convert AA to eicosanoids is highly regulated at the post- or co-transcriptional level by alternative mRNA splicing, alternative mRNA polyadenylation, mRNA stability, and microRNA (miRNA) regulation. This review article will highlight these mechanisms of mRNA modulation. (C) 2013 John Wiley & Sons, Ltd.
