Impact of biological sex on angiotensin-converting enzyme 2 (ACE2) activity in the rat kidney and lung. Shown is ACE2 enzyme activity in kidney (A) and lung tissue (B) from female (circle) and male (square) 2–4 mo-old Long-Evans rats at a substrate concentration of 50 µM. The data are presented as a scatter plot showing individual data points (n = 5–6) with the means and SE indicated by horizontal and vertical bars, respectively. The data were analyzed by an unpaired t test with Welch’s correction, *P < 0.05 vs. male.
