Figure 7.

Impact of biological sex on angiotensin-converting enzyme 2 (ACE2) activity in the hamster kidney, lung, and heart. Shown is ACE2 enzyme activity from 10 ng/µL of kidney tissue (A) and 50 ng/µl of lung (B) and heart (C) from female (circle) and male (square) 11-wk-old Syrian golden hamsters at 30 µM substrate concentration. The data are presented as a scatter plot showing individual data points (n = 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.
