Background Lysophosphatidic acid (LPA) and sphingosine 1-phosphate (S1P) are bioactive lipid signaling molecules implicated in tumor dissemination. also markedly invaded 3D collagen matrices (~700 m over 48 hours) in response to either lipid. siRNA focusing on of LPA1 and Rac1, or S1P1, Rac1, and Cdc42 specifically inhibited LPA- or S1P-induced HT1080 invasion, respectively. Analysis of… Continue reading Background Lysophosphatidic acid (LPA) and sphingosine 1-phosphate (S1P) are bioactive lipid
