Research Abstract

We clarified that phosphorylation of GATA-6 and GATA-6-associated cofactor HMGB1 positively regulate the transcriptional machinery for Nox1 gene in oncogenic Ras signaling. We identified 719 genes upregulated byGATA-6 and 1161 genes downregulated by GATA-6 in colon cancer cell-line CaCo-2. We also clarified the molecular mechanism for transcriptional repression of TOPORS gene by GATA-6.
