2004 MAR 4 - (NewsRx.com & NewsRx.net) -- LPA type-2 regulates a host of growth factors to control ovarian activity.
According to published research from the United States, "the lipid growth factor lysophosphatidic acid (LPA) is produced by ovarian cancer cells in quantities sufficient to attain concentrations of up to 10 microM. An autocrine circuit was demonstrated when ovarian cancer cells, but not normal ovarian surface epithelial cells, were proven to express LPA[subscript]2 (Edg-4) and LPA[subscript]3 (Edg-7) G protein-coupled receptors for LPA. Human LPA[subscript]2 now has been expressed transgenically in C57BL/6 mouse ovaries under direction of the alpha-inhibin large promoter."
"Human LPA[subscript]2 mRNA and protein were detected in all transgenic (TG) mouse ovaries at levels far higher than in other tissues and at least five-fold higher than in cultured lines of human ovarian cancer cells, with the expected sex cord-stromal distribution," reported M.C. Huang and colleagues, University of California, San Francisco, Medical Center.
"Most LPA[subscript]2 TG ovaries produced significantly higher levels than non-TG ovaries of type A, but not type B, vascular endothelial growth factor (VEGF), isomers of VEGF-A, and ...
