1 · What the graph read from it

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.

2 · The registry

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

backgroundAcute myeloid leukemia (AML) is a common hematological tumor, but it is difficult to treat. DNMT1 is a DNA methyltransferase whose main function is to maintain stable DNA methylation during the DNA replication process. DNMT1 also plays an important role in AML, but its function in cytokine-induced memory-like natural killer (CIML NK) cell activity remains unclear. METHODS AND

resultsIn this study, we isolated primary NK cells from the peripheral blood of healthy volunteers and AML patients and treated them with 10 ng/mL IL-12, 50 ng/mL IL-15 and 50 ng/mL IL-18 to promote their differentiation into CIML NK cells. The activity of CIML NK cells was evaluated by RT‒qPCR, western blotting, ELISAs, and flow cytometry. DNMT1 was highly expressed in NK cells from AML patients. Knocking down DNMT1 significantly increased the expression of CD25, CD137, CD107a, IFN-γ, and TNF-α and increased the activity of CIML NK cells. Mechanistically, knocking down DNMT1 promoted autophagy by activating the AMPK/mTOR signaling pathway, thereby enhancing the activity of CIML NK cells and alleviating the progression of AML.

conclusionsOur study revealed that the downregulation of DNMT expression may be a new target for the treatment of AML.
