| Outline of Final Research Achievements |
Enhanced expression of Annexin A4 (Anx A4) increases chemoresistance to plutinum through increased extracellular efflux of the drug. Exposure to platinum drugs induced relocation of Anx A4 from the cytoplasm to the cellular membrane, where it became colocalized with ATP7A, a copper transporter also well known as a mechanism of platinum efflux. Calcium-binding site in the annexin repeat induces chemoresistance to the platinum drug by elevating the intracellular chloride.
