KDM1A and cancer: Sun et al. also found that the lncRNA HOXA11-AS can recruit KDM1A (an H3K4me1/2 and H3K9me1/2 demethylase) and functions as a scaffold for KDM1A, EZH2, and DNA-methyltransferase 1 (DNMT1) in GC, resulting in the progression of cancer development.25 Moreover, KDMs are closely related both to each other and to other histone modification enzymes.
