However, expression can also be repressed by di-methylation of lysine 9 of histone 3 or by over-expression of a number of microRNAs including miR-181d, miR-767-3p and miR-603.
Porén, a expresión pode tamén ser reprimida por dimetilación da lisina 9 da histona H3 ou por sobreexpresión de diversos microARNs como miR-181d, miR-767-3p e miR-603.
