Experimental Protocol


Three DLD-1 clonal stable cell lines created by tetracycline-regulated expression (T-REx) system were treated with or without doxycycline for RNA extraction and hybridization on Affymetrix microarrays. One of the three cell lines is a mock cell line,a parental cell line that expresses only the Tet regulator and does not overexpress any protein when induced with doxycycline (Dox). The other three cell lines can be induced by Doxycycline to overexpress wild-type dnTCF-1E or a mutant form of dnTCF-1E with five amino acid substitution mutations in the C-clamp of the E-tail, or dnLEF-1. The mock cell line and dnLEF-1 cell lines were treated with or without Dox for 23 hr. The wild-type and mutant dnTCF-1E cell lines were treated with or without Dox for 8 and 23 hr, and as well, wild-type dnTCF-1E was induced with maximal amounts of Dox (hi: 1ug/ml) for maximum expression and gene expression regulation.
