Outline of Final Research Achievements

Based on our previous findings in malignant mesothelioma cells, we have examined the role of CTGF in other cancer cell lines including squamous cell carcinoma and osteosarcoma. Expression of CTGF was detected mainly in osteosarcoma cells, but not in squamous cell carcinomas. Knockdown of CTGF suppressed the growth of only in osteosarcoma cells, suggesting that CTGF plays critical role in the growth of osateosarcoma cells, but not in squamous cell carcinomas. These data suggested that Hippo-YAP-CTGF pathway plays an important role in the growth of malignant tumor originated from non-epithelial cells.
