Abstract

Plant-derived exosome-like nanovesicles (ELNs) are critical mediators of cross-kingdom communication, modulating gene expression in animal cells despite their plant origin. In this study, we investigated the effects of glucoraphanin-enriched kale (GEK)-derived ELNs (GELNs) on collagen production in normal human dermal fibroblasts NB1RGB. The ELNs isolated from GEK juice powder had particle sizes similar to those of typical exosomes. GELNs increased type I collagen expression in NB1RGB cells significantly. Microarray analysis demonstrated that GELN-derived total RNA upregulated the expression of genes related to extracellular matrix formation, including those involved in collagen synthesis. Further investigation revealed that microRNA-enriched fraction of GELNs promoted collagen production by inhibiting the expression of Smad7. These findings suggest that GELNs and their microRNA content enhance collagen production through the downregulation of Smad7.

期刊介绍： No subject pertains more to human life than nutrition. The aim of Frontiers in Nutrition is to integrate major scientific disciplines in this vast field in order to address the most relevant and pertinent questions and developments. Our ambition is to create an integrated podium based on original research, clinical trials, and contemporary reviews to build a reputable knowledge forum in the domains of human health, dietary behaviors, agronomy & 21st century food science. Through the recognized open-access Frontiers platform we welcome manuscripts to our dedicated sections relating to different areas in the field of nutrition with a focus on human health. Specialty sections in Frontiers in Nutrition include, for example, Clinical Nutrition, Nutrition & Sustainable Diets, Nutrition and Food Science Technology, Nutrition Methodology, Sport & Exercise Nutrition, Food Chemistry, and Nutritional Immunology. Based on the publication of rigorous scientific research, we thrive to achieve a visible impact on the global nutrition agenda addressing the grand challenges of our time, including obesity, malnutrition, hunger, food waste, sustainability and consumer health.
