Inhibitory effect of glycoprotein isolated from Cudrania tricuspidata bureau on expression of inflammation-related cytokine in bisphenol A-treated HMC-1 cells.
Cudrania tricuspidata is one of the most omnipresent traditional herbal drugs for anti-inflammation and anti-tumor. The purpose of the present study was to determine whether the CTB glycoprotein regulates the inflammatory reaction stimulated by bisphenol A (BPA) in human mast cells (HMC-1). Thus, we investigated that CTB glycoprotein inhibits the degranulation of histamine, expression of extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK), as a mitogen activated protein (MAP) kinase, nuclear transcription factors involving nuclear factor (NF)-kappaB and Activator protein (AP)-1, cyclooxygenase (COX)-2. The results indicated that CTB glycoprotein decreased gene expression of cytokines of IL-4, IFN-gamma, interleukin (IL)-1beta and cyclooxygenase (COX)-2 in BPA-stimulated HMC-1 cells. Hence, we speculate that CTB glycoprotein can use as a potent anti-inflammatory agent for inflammatory allergic diseases.
