EZH2 inhibition using GSK126 significantly upregulated MALAT1 expression in three SOX11 positive MCL PDLS growing with or without pro-proliferative factors. The inhibitor was used at two 10-fold different concentrations, and we could observe a highly significant increase in MALAT1 expression upon the treatment with the highest dose of the inhibitor in all cases with pro-proliferative factors and nearly all in their absence.
