Outline of Final Research Achievements |
I identified TSHZ2 as a down-regulated gene during breast carcinogenesis. TSHZ2 was found to make a ternary complex with GLI1 and CtBP2 in the nucleus of normal duct epithelium and suppress the target gene expression of GLI1. This indicates that down-regulated TSHZ2 and in turn up-regulated target genes of GLI, such as CXCR4 and AEBP1, would be responsible for breast cancer progression. I next identified FAM64A, FAM83D, DLGAP5, FOXM1 and DONSON as candidates of TSHZ2 target genes. Especially, I found that FAM64A associates with several nuclear proteins which are involved in chromatin remodeling and DNA replication.
