Mature ADAM10 protein levels were significantly reduced in eNOS+/−
microvascular tissue. (a) Microvascular tissue from 18-month-old eNOS+/−
and wild type animals was Western blotted using anti-APP, anti-BACE1, anti-ADAM10,
and anti-Actin (loading control) antibodies. Representative image is shown.
Densitometric analysis was performed for (b) APP (n = 6 animals),
(c) BACE1 (n = 7 animals), and (d) ADAM10 (n = 5
animals; *P < 0.05). BACE enzymatic activity was measured from
18-month-old eNOS+/− and wild type (e) microvascular tissue via a
commercially available BACE activity assay kit (n = 3–4). All data
are presented as mean ±SD with individual data points shown.
