Long Intergenic Non-Coding RNA HOTAIRM1 Regulates Cell Cycle Progression During Myeloid Maturation in NB4 Promyelocytic Leukemia Cells


ABSTRACT: HOTAIRM1 is a long intergenic non-coding RNA located in the human HOXA gene cluster, with gene expression highly specific for maturing myeloid cells, particularly during all-trans retinoic acid (ATRA) induction of granolopoiesis in NB4, a human t(15;17) acute promyelocytic leukemia (APL) cell line. We sought to assess the impact of HOTAIR knockdown on the global programme of gene expression underlying the granulocytic maturing process in NB4 cells. The knockdown of HOTAIRM1 resulted in a less differentiated expression profile in the NB4 cells after 4 days of ATRA-induced granulocytic differentiation, with retained expression of many otherwise ATRA-suppressed cell cycle and DNA replication genes, as well as abated induction of cell surface leukocyte activation and defense response genes.
