Table 2. mRNA levels of components of the renin-angiotensin system in WT and ACE2 KO mice after sham operation or I/R.

Components	WT sham (n = 5)	ACE2 sham (n = 5)	WT IR (n = 7)	ACE2 IR (n = 6)
ACE	0.70±0.06	0.89±0.09	1.06±0.35	0.36±0.12
ACE2	0.74±0.04	N.D.	2.13±0.85	N.D.
Angiotensinogen	0.69±0.06	1.07±0.23	2.37±0.69	0.85±0.18
Renin	0.68±0.08	1.01±0.19	2.31±1.00	1.62±0.32
AT1R	0.73±0.06	0.67±0.07	2.31±0.71	1.21±0.17
Mas	0.68±0.12	0.84±0.10	1.14±0.33	0.78±0.30

Values are expressed as fold change versus WT sham and presented as mean ± SE. N.D., non-detectable.
