Proteasome activity (AU) in the hearts of Arctica islandica. Relationships between changes with age of chymotrypsin-like activity (A) (regression analysis: n = 19, F = 48.864, p = 0 < .001, r 2 = .73), trypsin-like activity (B) (regression analysis: n = 19, F = 3.235, p = .089, r 2 = .105), and caspase- like activity (C) (regression analysis: n = 19, F = 0.629, p = .438, r 2 = .001).
