Galangin, a natural flavonol, has attracted much attention for its potential
anti-inflammatory properties. However, its role in the regulation of airway
remodelling in asthma has not been explored. The present study aimed to elucidate
the effects of galangin on chronic inflammation and airway remodelling and to
investigate the underlying mechanisms both in vivo and in vitro. Ovalbumin
(OVA)-sensitised mice were administered with galangin 30?min before challenge.
Our results showed that severe inflammatory responses and airway remodelling
occurred in OVA-induced mice. Treatment with galangin markedly attenuated the
leakage of inflammatory cells into bronchoalveolar lavage fluid (BALF) and
decreased the level of OVA-specific IgE in serum. Galangin significantly
inhibited goblet cell hyperplasia, collagen deposition and ?-SMA expression.
Lowered level of TGF-?1 and suppressed expression of VEGF and MMP-9 were observed
in BALF or lung tissue, implying that galangin has an optimal anti-remodelling
effect in vivo. Consistently, the TGF-?1-induced proliferation of airway smooth
muscle cells was reduced by galangin in vitro, which might be due to the
alleviation of ROS levels and inhibition of MAPK pathway. Taken together, the
present findings highlight a novel role for galangin as a promising
anti-remodelling agent in asthma, which likely involves the TGF-?1-ROS-MAPK
pathway.
