OBJECTIVE: We investigated the correlation between the methylation of LIVIN gene and the pathogenesis of bone tumor at the molecular level, in order to improve the treatment method and enhance the cure rate of bone tumor.
PATIENTS AND METHODS: The expression level of Livin protein was detected using Western blot analysis, and its expressions in control group and patients were detected by immunohistochemistry. The methylation frequency of LIVIN gene was calculated by direct sequencing. Finally, the prognosis of treatment was investigated by follow-up.
RESULTS: The experiment found that Livin protein was not expressed in normal cells, while its expression rate was about 71.4% in 112 patients. The methylation frequency of LIVIN gene was gradually decreased with the increase of clinical stage, and had no significant relationship with age and sex. The prognosis experiment indicated that the lower the methylation frequency of LIVIN gene was, the shorter the survival time would be.
CONCLUSIONS: The methylation of LIVIN gene was closely related to the pathogenesis of bone tumor, which may be one of the important factors to induce the formation of a bone tumor. In addition, the methylation frequency of LIVIN gene could be used as a biomarker for the prognosis of bone tumor treatment.Free PDF Download
