Additionally, BORIS positively regulates some of the CTAs by binding and inducing a shift to a more open chromatin conformation with promoter hypomethylation of MAGEA3, or independently of promoter hypomethylation in case of MAGEA2 and MAGEA4 and thus may be a key effector involved in their de-repression in lung cancer [106]. This evidence concerns the gene CTCFL and lung carcinoma.
