Reporter gene responses upon stimulation of RXFP1 (A) or RXFP1-short (B) stably expressed in HEK293T cells using 100 nm H2 relaxin. Data are -fold change of response from vehicle. Symbols represent means, and vertical bars represent S.E. of triplicate determinations from three independent experiments. GRE, glucocorticoid response element; AP1, activator protein 1; SRE, serum response element; NFAT, nuclear factor of activated T cells; HSE, heat shock element.
