Polycomb group protein complexes control gene repression through recruitment of histone deacetylase. This recruitment leads to trimethylation of Lys27 of histone H3 (H3K27). Histone H3K27 trimethylation is a property of stably silenced heterochromatin. EZH2 and BMI-1 are pivotal components of polycomb group protein complexes. Increased EZH2 levels have been found in several malignancies and reported as a molecular biomarker of poor prognosis. Similarly, BMI-1 has also been found to be associated with malignant transformation. In addition, inhibition of EZH2 or BMI-1 inhibits the growth of various types of malignancies. The expression of BMI-1 and EZH2 in human osteosarcoma has not been clearly determined. We examined the potential involvement of aberrant polycomb group protein expression in the pathogenesis of osteosarcoma. Real-time PCR revealed that expression of EZH2 in 143B, HOS, NOS-1 and Saos2 was increased compared to normal osteoblasts. BMI-1 was also up-regulated in 143B, HOS and NOS-1. Expression of EZH2 and BMI-1 were up-regulated in osteosarcoma patient biopsy specimens compared to normal bone. Immunohistochemical examinations showed that EZH2 and BMI-1 were up-regulated in osteosarcoma cells and that trimethylation of histone H3K27 was increased. We examined the effects of knock down of EZH2 and BMI-1 by shRNA. Unexpectedly, the knock-down of EZH2 and BMI-1 did not prevent osteosarcoma growth either in vitro or in vivo. Our findings suggest that EZH2 and BMI-1 may be tumorassociated antigens of osteosarcoma, but are not useful molecular targets of osteosarcoma treatment.", "subitem_description_type": "Other"}]},
