coupled receptors for lysophosphatidic acid (LPA). Based on baculoviral overexpression
studies, differences have been proposed in the structure-activity relationship (SAR) of these
receptors. We have compared the SAR of the individual receptors either overexpressed
transiently at high or at lower levels following stable transfection in LPA-nonresponsive
RH7777 cells. The SAR in transfected RH7777 cells was markedly different from that …
