Abstract

Human promyelocytic HL‑60 cells can be differentiated into macrophage‑like cells by treatment with 12‑O‑tetra decanoylphorbol‑13‑acetate (TPA). Certain 5' upstream regions of the zinc finger protein (ZNF)‑encoding genes contain duplicated GGAA motifs, which are frequently found in the TPA‑responding gene promoter regions. To examine transcriptional responses to TPA, 5'flanking regions of human zinc finger CCCH‑type containing, antiviral, ZNF252, ZNF343, ZNF555, ZNF782 and zinc finger nfx‑1‑type containing 1 (ZNFX1) genes were isolated by polymerase chain reaction (PCR) and ligated into a multiple‑cloning site of the pGL4.10[luc2] vector. Transient transfection and a luciferase assay revealed that the ZNFX1 promoter most prominently responded to the TPA treatment. Deletion and point mutation experiments indicated that the duplicated GGAA motif in the 100‑bp region positively responded to TPA. In addition, reverse transcription‑quantitative PCR and western blotting showed that the mRNA and protein of ZNFX1 accumulate during the differentiation of HL‑60 cells. These results indicated that expression of the TPA‑inducible ZNFX1 gene, which belongs to the group of interferon‑responsive genes, is regulated by the cis‑action of the duplicated GGAA motif.
