ETAR and ETBR mRNA and protein during hypoxia exposure and inhibition of TGF-β signaling

	DT-Saline-Air (Control)	DT-Saline-Hypoxia	DT-Zinc-Air	DT-Zinc-Hypoxia
ETAR
mRNA	1.0 ± 0.16	1.7 ± 0.43	1.4 ± 0.18	1.7 ± 0.4
Protein	1.0 ± 0.15	1.2 ± 0.03	1.2 ± 0.06	1.3 ± 0.05
ETBR
mRNA	1.0 ± 0.16	3.3 ± 0.03*	2.4 ± 0.35†	2.7 ± 0.33
Protein	1.0 ± 0.09	1.3 + 0.05	1.4 + 0.1	1.2 + 0.08

Values are normalized to expression in DNTGFβRI (DT)-Saline-Air (Control) and are means ± SE; n = 6/group. ETAR and ETBR mRNA is by quantitative PCR, and protein is by densitometry of Western blots expressed in arbitrary units.
