ADAM17 siRNA attenuated Ang II-induced inflammation in vascular smooth muscle cells. After being transfected with 100 nmol/l ADAM17 siRNA for 30 hours, vascular smooth muscle cells were then stimulated with 100 nmol/l Ang II for 24 hours. (a) ADAM17 protein level, n = 4 independent experiments. (b) ADAM 17 mRNA level, n = 3 independent experiments. (c–e) At the end of the experiment, the medium was collected to detect the concentration of IL-1β, IL-6, and TNF-α by ELISA, n = 3–5 independent experiments. (c) IL-1β protein level. (d) IL-6 protein level. (e) TNF-α protein level. (f) The mRNA levels of IL-1β, IL-6, and TNF-α, n = 3 − 4 independent experiments. Ang II: angiotensin II; NC: negative control. ∗
