... The increased expression of FOXQ1 could be due to a hyperactive Wnt pathway in these tumors. Wnt activity directly correlates with FOXQ1 expression in colorectal cancer cell lines and β-catenin can bind to the promoter of FOXQ1 and increase transcription (Christensen et al., 2013). FOXQ1 expression ...

Mutagen



In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called ""spontaneous mutations"" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
