The Harakiri (HRK) gene encodes an important proapoptotic mitochondrial protein of the Bcl-2 family. HRK is expressed in normal tissues but is decreased in many cancers such as melanoma, the mechanisms of which have not been fully elucidated. Here, we demonstrate that HRK is silenced by hypermethylation of a major proximal CpG island in the HRK promoter.(More)
BACKGROUND The transcription factors Sp3/Sp1 are expressed in a various types of cancers and BNIP3 is overexpressed in prostate cancer. Although it has been demonstrated that BNIP3 is transcriptionally regulated by HIF-1α and is post-transcriptionally regulated by miR145, our previous data indicated that there might be some other transcription factors(More)
The SOX4 (sex-determining region Y-related high-mobility-group box transcription factor 4) gene plays critical roles in embryonic development and cell-fate determination. Recently, SOX4 overexpression has been found in various tumors. However, its expression status and prognostic significance in astrocytoma remain unknown. In this study, SOX4 expression in(More)
The transcriptional factor AP-2α is a tumor suppressor gene and is downregulated in various neoplasms including glioma. Although the level of AP-2α is negatively associated with the grade of human glioma, the specific functions of AP-2α in glioma are still unknown. In this study, we experimentally showed that artificial overexpression of AP-2α in glioma(More)
