Figure 5. Apelin inhibits A23187-induced relaxation of isolated cerebral arteries.

Figure 5.

Log concentration-response curves to A23187 in the absence and presence of (A) apelin (10−7 M; n=7); (B) iberiotoxin (IBTx, 10−7 M; n=6); (C) combination of apelin and IBTx; (n=6); and (D) apelin with and without F13A (10−7 M); n=6). Data are expressed as a percentage of the initial increase in tension induced by 5-HT (10−7 M). Values are represented as means ± S.E.M. *p<0.05 vs. A23187 alone.
