The invention relates to the use of PDCD5 polypeptides or polynucleotides that code the PDCD5 polypeptides in preparation of sensitizers of chemotherapeutic agents for cancers. The invention also relates to the use of PDCD5 polypeptides or polynucleotides that code the PDCD5 polypeptides to protect normal or diseased tissues or organs from damages or further damages, and to pharmaceutical combinations including chemotherapeutic agents and PDCD5 polypeptides or polyneucleotides that code the PDCD5 polypeptides in an amount for effective sensitization. Preferably, the pharmaceutical agents are selected from antibiotic and anti-metabolic agents or any combination thereof.
