Figure 5.
LIMP-2 expression is up-regulated in other forms of mechanical loading. In neonatal rat cardiac myocytes, 6 h of stretch elevated LIMP-2 mRNA expression (n = 4 per group) (a). LIMP-2 expression was also up-regulated in hypertrophic myocardium from rats that had undergone exercise training for 10 wk (5 d per week; n = 6) as compared with nonhypertrophic control rats (n = 7) (b). After 1 h of transverse aortic banding in mice, LIMP-2 protein is elevated (c). LIMP-2 mRNA is up-regulated in hypertrophic patients with aortic stenosis (LVH; n = 20) as compared with nonhypertrophic control patients (n = 7) (d). *, P < 0.05 versus control; **, P < 0.01 versus control; LVH; LV hypertrophy.
