H19 expression is induced in the NB4-LR1SFD cells by alternative treatments. Expression levels of H19, hTERT, and hTR and telomerase activity after treatment of NB4-LR1SFD cells for 48 h with ATRA (1 μM) alone or in combination with either 8-CPT-cAMP (100 μM) or Arsenic trioxide (As2O3, 0.2 μM).. Expression levels were normalized to GAPDH expression. Results were expressed as means +/− SEM. t-test or one way ANOVA with post-hoc Tukey, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
