Abstract

Centella asiatica, a traditional medicinal plant, possesses potent antioxidant activity and may therefore prevent cellular aging and exert antiapoptotic effects. However, these effects remain to be fully elucidated. This study aimed to investigate the protective effects of C. asiatica extract against cellular senescence and apoptosis caused by hydrogen peroxide (H2O2)-induced oxidative stress in human epidermal keratinocytes (HaCaT cells). To evaluate the effects of H2O2 and C. asiatica on HaCaT cells, we measured cell viability as a marker of cell death; reactive oxygen species (ROS), radical scavenging, superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase activities as markers of oxidative stress; senescence-associated β-galactosidase (SA-β-gal) activity as a marker of cellular senescence; and caspase-3/9 activities and apoptotic cells as markers of apoptosis. H2O2 induced cell death (decreased cell viability), oxidative stress (increased ROS activity, decreased radical scavenging, SOD, GPx, and catalase activities), cellular senescence (increased SA-β-gal activity), and apoptosis (increased early/late apoptotic cells and increased caspase-3/9 activities). C. asiatica significantly decreased all markers of H2O2-induced cell death, oxidative stress, cellular senescence, and apoptosis, suggesting its ability to prevent cellular senescence and apoptosis through its antioxidant activity. This mechanism of action may contribute to the prevention and improvement of skin aging.

期刊介绍: Biology (ISSN 2079-7737) is an international, peer-reviewed, quick-refereeing open access journal of Biological Science published by MDPI online. It publishes reviews, research papers and communications in all areas of biology and at the interface of related disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
