Patent ID: 8343940

Claim:
A method for enhancing sensitivity of lung cancer cells to cisplatins or gamma-radiation, comprising: administering to lung cancer cells having resistance to cisplatins and gamma-radiation an anticancer supplement agent comprising an inhibitor of the expression of testis protein, Y-encoded-like 5 (TSPYL5) protein, wherein said TSPYL5 protein has an amino acid sequence of SEQ ID No: 1, wherein the inhibitor of the expression of the TSPYL5 protein is an antisense oligonucleotide or nucleic acid that is complementary to TSPYL5 mRNA and can bind to the mRNA thereby inhibiting expression of the mRNA, or a small interfering RNA (siRNA) that is complementary to TSPYL5 mRNA and can bind to the mRNA thereby inhibiting expression of the mRNA.
