| Research Abstract |
This study was aimed to identify genetic polymorphisms of ORM genes(ORM1 and ORM2), encodingα-1-acid glycoprotein(AGP), which might affect anti-cancer drug responses. Detailed analysis on ORM gene structures(duplication/deletion) and genetic polymorphisms/haplotypes were conducted for Japanese cancer patients who received paclitaxel(PTX)-therapy, and the association of ORM genotypes with serum AGP levels and PTX-pharmacokinetics were investigated. As a result, ORM genetic polymorphisms related to increased levels of serum AGP and the area under the plasma concentration-time curves of PTX-metabolites were identified. A luciferase reporter gene assay indicated existence of putative promoter regions which might be responsible for different regulatory mechanisms of gene expression between ORM1 and ORM2.Possible influence of the ORM genetic polymorphism on the reporter activity was also examined.
