Abstract
|
|
|
Objective : This study investigated the effects of PR(Pinelliae Rhizoma) on gene expression of lung tissue resected from asthma induced mice using intra-nasal instillation.
Methods : Gene expression levels were measured using a microarray technique, and a functional analysis on these genes was conducted.
Results : A total of 3270 genes were up-regulated or down-regulated, 860 genes which were lowered by induction of asthma were restored to those of naive animals, Furthermore hand, 1235 genes were lowered to normal levels, which were elevated by induction of asthma. Most of changed genes were involved in signalling pathways. Genes in which expression levels were restored by oral administration of PR were involved in MAPK pathway, focal adhesion, and regulation of actin cytoskeleton etc. Genes of which expression levels were lowered by oral administration of PR were involved in rhodopsin-like receptor activity, zinc ion binding and ATP binding. These genes were also involved in neuroactive ligand receptor interaction, the JAK-STAT signaling pathway and also the T-cell receptor signaling pathway.
Conclusion : These results demonstrate the strong possibility that the mechanisms of PR on asthma are involved in neuroactive ligand receptor interaction pathway or related molecules.
