Outline of Final Research Achievements |
We showed arsenic trioxide targets GLI2, a crucial factor for intracellular signaling of musculoskeletal tumors, and suppressed growth of osteosarcoma cells. ATO is already approved for leukemia, therefore translation into clinical usage for osteosarcoma is anticipated. We also showed that Surv.m-CRA, a survivin-responsive conditionally-replicative adenovirus (CRA), exhibit strong antitumor activity to rhabdomyosarcoma stem cells. We found that ribosomal protein S3 is a target gene of GLI2 and its knockdown suppressed invasion and motility of osteosarcoma cells. We are preparing for clinical trial of Surv.m-CRA for musculoskeletal tumor patients, which is expected to further advance the research of gene therapy for musculoskeletal tumors.
