This work explores a strategy using drug all-transretinoic (ATRA) combined with nanodiamond (ND) and blue light (BL) irradiation on the typical HL60 cell line, to establish a approach for improving the treatment efficacy of human leukemia cells.

Abstract Retinoic acid is known to induce differentiation of human myeloid leukemia cells in vitro. Recently, all-trans retinoic acid has been used to induce remissions in patients with acute promyelocytic leukemia, probably through differentiation of the leukemia cells. Myeloblastin (mbn) is a protease that has been identified in the human leukemia cell line HL-60. Downregulation of this protease can inhibit proliferation and induce differentiation of HL-60-derived leukemia cells. Here we have investigated the regulation of mbn messenger RNA (mRNA) expression in two human leukemia cell lines, HL-60 and NB4, treated with all-trans retinoic acid. Under this treatment, downregulation of mbn mRNA was observed in both cell lines, but was considerably delayed in NB4 cells that carry the t(15;17) translocation characteristic of acute promyelocytic leukemia. We have found that multiple mechanisms were involved in the control of mbn mRNA expression. These mechanisms were different in HL-60 and NB4 cells. Our results show that in HL-60 cells, all-trans retinoic acid rapidly decreased transcription of mbn. In contrast, in the t(15;17)-positive NB4 cells treated with all-trans retinoic acid, upregulation of mbn mRNA expression was followed by a late downregulation, both achieved via posttranscriptional mechanisms.
