Lung expression of RNA transcripts of renin-angiotensin system components in SD and Ren2 rats. Angiotensin type 1 receptor (AT1R; A), angiotensinogen (B), and angiotensin-converting enzyme (ACE; C) mRNA were examined via RT-PCR in 9-wk-old male SD and Ren2 rats. Bar graphs show band densities (means ± SE) for each transcript normalized to GAPDH (n = 5). Bands displayed above each bar graph are representative of each transcript and corresponding GAPDH. *Statistically significant difference between the two groups.
