In this study we report synergistic antitumor activity of Laccaic acid (LA) and Phenethyl isothiocyanate (PEITC) combination in colorectal cancer via dual inhibition of DNA methyltransferase-1 and Histone deacetylase-1.
Promoter methylation of the p14(ARF) gene and messenger RNA (mRNA) expression levels of p14(ARF), DNA methyltransferase 1 (DNMT1), and DNMT3b were investigated by using methylation-specific polymerase chain reaction (PCR) analysis (MSP) and quantitative real-time PCR analysis in fresh tissues from 188 patients with colorectal cancer.
In summary, we present the first comprehensive proteomic analysis of the widely studied Dnmt1 hypomorph colorectal cancer cells and identify redistribution of Dnmt1 and its interaction partner Beta-Catenin.
