Expressions of IP and TP receptors in HTN carotid arteries.

<p><b><i>A</i>:</b> comparison of mRNA levels of IP and TP receptors detected with real-time PCR between HTN and NTN arteries (normalized to β-actin with the average value of NTN vessels assumed as 1.0; n = 6 for each). <b><i>B</i>:</b> β-actin normalized levels of IP and TP receptor mRNAs in HTN arteries and those denuded of the endothelium [HTN + EC (-)] with the average value of control HTN vessels assumed as 1.0 (n = 3 for each). Values were expressed as mean ± SEM; NS, not significant.
