| Research Abstract |
SIX3 protein was expressed in the normal duct cells of the pancreas whereas not in PanIN/cancer cells. Human SIX3 promoter contained a CpG island which was methylated in SIX3(-) pancreatic cancer cell lines. Reporter assay revealed roles of SIX3 and TLE1/HDAC1 in the MACS1-dependent suppression of human Shh gene. SIL was strongly expressed in PanIN/cancer cells of the pancreas. It was also weakly expressed at the basal of the normal duct cells of the pancreas, indicating its role for the cellular attachment to the matrix.
