Expression levels of miR-29b in the LV tissue and plasma in patients. (A) relative miR-29b expression in the LV (RE vs. RNU6b) from control individuals under 50 years (n = 6 men, n = 8 women) and over 50 years (n = 11 men, n = 15 women) of age, and (B) in plasma (RE vs. Cel-39) from control individuals under 50 years (n = 5 men, n = 8 women) and over 50 years (n = 10 men, n = 13 women) of age. (C) miR-29b expression in the LV from control patients (11 men, 15 women) and patients with AS (45 men, 50 women) over 50 years of age, and (D) in plasma from control patients (10 men, 13 women) and patients with AS (38 men, and 46 women) over 50 years of age. Data are means ± SE. * p < 0.05, ** p < 0.01, *** p < 0.001 (Kruskal–Wallis followed by Dunn’s post hoc test).
