Effect of miRNA-19a antisense oligonucleotide and Ara-C on the proliferation and apoptosis of HL60 cells.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study aimed to investigate the effects of microRNA19a (miR-19a) antisense oligonucleotide (ASODN) on the proliferation and apoptosis of acute myeloid leukemia cells (HL60).
methodsIn 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.
resultsMiR-19a expression in the miR-19a ASODN group was lower than in the SODN group and the blank control group (P<0.05). MiR-19a ASODN significantly inhibited the growth of HL60 cells (P<0.05) and increased their apoptosis, and the apoptosis rate peaked at 48 h. The protein expression of E2F1 and Bim in the ASODN group was higher than in the blank control group, blank transfection group and SODN group. In addition, Ara-C further inhibited the growth and induced the apoptosis of miR-19a ASODN-transfected cells (P<0.05) in a time dependent manner. The growth inhibition rate and apoptosis rate in the ASODN + Ara-C group were higher than the sum of those in both Ara-C group and ASODN group.
conclusionsmiRNA-19a ASODN can inhibit the proliferation and induce apoptosis of HL60 cells and may exert synergistic effects with Ara-C on HL60 cells.
