Abstract
ABSTRACT Cypress tree (Chamaecyparis obtusa) bark is well-known for its bio-functional activities and high content of polyphenol and flavonoids. It has previously exhibited antioxidant, anti-pathogenic, and anti-inflammatory activities. Our study aimed to investigate the anti-melanogenic effect of Cypress Tree Bark extract (CBE). We evaluated cellular tyrosinase activity and melanin content in alpha-melanocyte-stimulating hormone (α-MSH) induced B16F10 murine melanoma cells. We analyzed microphthalmia-associated transcription factor (MITF), tyrosinase-related protein (TRP1 and TRP2), and cAMP response element-binding protein (CREB) activation via phosphorylation of AKT and ERK using western blot analysis. Tyrosinase, MITF, TRP1, and TRP2 mRNA expression were examined via real-time polymerase chain reaction. CBE restored melanin content and tyrosinase activity remarkably in α-MSH stimulated melanoma cells. It exhibited an anti-melanogenic effect through suppressing MITF, TRP1, TRP2, tyrosinase mRNA and protein expression in α-MSH-induced B16F10 cells. Furthermore, CBE has significantly inhibited CREB activation by suppressing AKT and extracellular signal-regulated kinase phosphorylation. Our data strongly suggest that CBE has potential effects against melanogenesis. GRAPHICAL ABSTRACT Graphical Abstract: The proposed mechanism of CBE on anti-melanogenic effect.
期刊介绍:
Food and Agricultural Immunology is an international open access journal publishing original immunological research with applications in food, agricultural, environmental and veterinary science. Submissions describing the use of immunological techniques and methods are particularly welcomed.
The journal aims to expand our understanding of the interactions at the interface of food and immune systems including studies on:
-Development of diagnostic systems – all types of ligand-based assays, e.g. antibody, aptamer
-Application of ligand-based assays for the detection or identification of molecules of interest in food science, agricultural research, veterinary investigations and clinical systems relating to food allergy or sensitivity to agricultural chemicals
-Effects of food on the immune system
-Studies on allergy and allergic reactions
-Investigations into food allergies
-Development of allergen-free food systems
-Development of novel assay formats
-Applications of assay systems to the monitoring of food items in relation to safety and labelling
-Food quality issues, e.g. speciation, adulteration and contamination
-Comparisons between different analytical techniques
The journal publishes research and review articles and is essential reading for food scientists, immunologists and all those concerned with the interaction between food and immune systems.
