Stimulation of Cytoglobin Expression and Improvement in ROS-Related Aging Markers in Skin Cells with Tropaeolum majus Extract
2025
Overview
Reactive oxygen species (ROS) and mitochondrial dysfunction play a major role in skin aging. Due to Tropaeolum majus’ suggested protective actions against ROS, a link between T. majus extract and increased cytoglobin (CYGB) expression was evaluated for cultured skin cells. Human dermal fibroblasts and keratinocytes were treated with 0.5% v/v T. majus extract and the effect of this treatment on the expression of CYGB and on a range of cellular markers of aging were evaluated. In fibroblasts, the treatment with the extract was associated with an increase in CYGB levels. It also decreased ROS concentrations, improved the function of mitochondria, and stimulated the synthesis of collagen and elastin. Moreover, it downregulated a set of genes controlling the terminal differentiation of keratinocytes. T. majus extract activates oxygen transport within natural killer cells and thus enhances their activity, suggesting a potential senolytic effect. This extract seemed to exert a protective effect on various aging pathways such as ROS production, mitochondrial dysfunction, and collagen homeostasis, playing a promising role against skin aging.
