BACKGROUND Curcumol, possessing antiviral, antifungal, antimicrobial, anticancer, and anti-inflammatory properties, has been widely used in treating cancers and liver fibrosis. The aim of this study was to determine the effect of curcumol on the progression of asthma. METHODS Curcumol was administrated to platelet-derived growth factor (PDGF)-BB-stimulated airway smooth muscle cells (ASMCs). The proliferation of ASMCs was assessed by MTT and EdU incorporation assays. The apoptosis of ASMCs was measured by flow cytometry and Western blotting. The migration of ASMCs was evaluated by Transwell migration assay and Western blotting. The regulatory effects of curcumol on extracellular signal-regulated protein kinase (ERK)/cAMP response element-binding protein (CREB) pathway was evaluated by Western blotting. RESULTS The proliferation and migration of ASMCs induced by PDGF-BB was suppressed, and the apoptosis of ASMCs was elevated by curcumol in a dose-dependent manner. The activation of ERK/CREB pathway induced by PDGF-BB was suppressed by curcumol. CONCLUSIONS Curcumol could suppress ERK/CREB pathway to inhibit proliferation and migration and promote apoptosis of PDGF-BB-stimulated ASMCs. These findings suggest that curcumol may act as a potential drug for asthma treatment.

D015398 Signal Transduction The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
