NEAT1 and acute promyelocytic leukemia: In de novo acute promyelocytic leukemia (APL), NEAT1 levels are significantly reduced: Zeng et al. reported that the promyelocytic leukemia-retinoic acid receptor α (PML-RARα) fusion protein inhibits NEAT1 expression, while the latter is significantly upregulated in APL cells treated with all-trans retinoic acid (ATRA) 104.
