This study tested the activity of LD-1227, which contains a caviar-derived homogenate added with coenzyme Q(10) (CoQ(10))-selenium component (CaviarLieri(®), Lab-Dom, Switzerland), in aged human skin and its potential role on skin mitochondria function. Human dermal fibroblasts were obtained from healthy donors over 70 years old and treated with LD-1227 for 72 hr. As compared to baseline, LD-1227 caused a robust (>67%) collagen type I synthesis (p<0.001) and decreased fibronectin synthesis (p<0.05) with significant fibronectin messenger RNA (mRNA) downregulation (p<0.05, r=0.78). A significant collagen mRNA overexpression occurred with LD-1227 treatment (p<0.05). Mitochondria cytosolic adenosine triphosphate (ATP) level decreased in aged skin samples (p<0.05 vs. young control), but this phenomenon was reversed by LD-1227 (p<0.01). These data show that LD-1227 may modify the extracellular matrix milieu in aged skin and also beneficially affect mitochondrial function.
