Ang II increased death rate due to aneurysm rupture during AAA formation compared with the control group (P < .05), whereas NONO down‐regulation reversed both high mortality (8%, 36%, 44% and 32%, P < .05 vs the control group, Figure 2G) and rupture rate compared with the control group (0, 24%, 28% and 12%, P < .05 vs the control group, #P < .05 vs no treatment group, &P < .05 vs Sh‐NC group, Figure 2H). Here, AGT is linked to aneurysm.
