Figure 1From: Up-regulation of endothelin type B receptors in the human internal mammary artery in culture is dependent on protein kinase C and mitogen-activated kinase signaling pathways (A) Endothelin-1 contractions (after ET B receptor desensitisation) and (B) ET A receptor mRNA levels in cultured and non-cultured human internal mammary arteries, examined using in vitro pharmacology (n = 27) and real time PCR (n = 8) experiments. The results are shown as mean values ± S.E.M. Statistical analyses, comparing cultured with non-cultured, were performed using Student's t-test. There were no significant differences.Back to article page
