	abstract = {Background: This study aimed to investigate the effects of microRNA19a (miR-19a) antisense oligonucleotide (ASODN) on the proliferation and apoptosis of acute myeloid leukemia cells (HL60). 
Methods: In experiment 1, HL60 cells were divided into the blank control group, the blank transfection group, the scrambled oligonucleotide (SODN) group and the ASODN group. MiR-19a ASODN and SODN were independently transferred into HL60 cells. The miR-19a expression was detected by real-time quantitative RT-PCR (qRT-PCR) after 48-h and 72-h transfection; CCK8 assay was used to detect the proliferation inhibition rate at 48 and 72 h; Hoechst 33258 staining was performed to examine apoptotic cells at 48 h; the apoptosis rate was detected by flow cytometry after AnnexinV/PI staining at 48 and 72 h; the protein expression of E2F1 and Bim was detected by Western blotting at 48 h. In experiment 2, cells were divided into the Ara-C group, the SODN + Ara-C group and the ASODN + Ara-C group. The cell proliferation inhibition rate at 48 and 72 h and apoptosis rate at 72 h were assessed as mentioned above. 
Results: MiR-19a expression in the miR-19a ASODN group was lower than in the SODN group and the blank control group (P},
