Lysophosphatidic Acid Up-Regulates Expression of Interleukin-8 and -6 in Granulosa-Lutein Cells through Its Receptors and Nuclear Factor-κB Dependent Pathways: Implications for Angiogenesis of Corpus Luteum and Ovarian Hyperstimulation Syndrome

Abstract

LPA induces IL-8 and IL-6 expressions through LPA receptors and nuclear factor-kappaB dependent pathways in granulosa-lutein cells. The LPA in preovulatory follicles may play a role in the angiogenesis of corpus luteum. Large amounts of LPA-induced IL-8 and IL-6 from multiple corpora luteae of stimulated ovaries may be one of the pathophysiological causes of ovarian hyperstimulation syndrome.
