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

purposeTo investigate the effect of silencing the YKL-40 gene on the expression of inflammatory factors and the effect of silencing the YKL-40 gene of THP-1 cells on endometrial cancer.

methodsWe used a siRNA targeting a sequence in YKL-40 (si-YKL-40) to transfect HEC-1A and THP-1 cells. Quantitative real-time polymerase chain reaction assay was performed to investigate the mRNA levels of YKL-40, IL-8 and MMP-9 in HEC-1A and THP-1 cells. Migration, and invasion assays were performed to identify the effects of co-culture with THP-1 cells that silenced YKL-40 gene on the migration and invasion capacity of HEC-1A cells. Tube formation ability were detected by Matrigel-based angiogenesis assay.

resultsWe successfully transfected HEC-1A and THP-1 cells with lentivirus to silence the YKL-40 gene. Compared with the blank control group and NC group, the expression of YKL-40, IL-8 and MMP-9 which were examined by qRT-PCR in YKL-40-siRNA group was significantly reduced in the two cell lines; after co-cultured with the supernatant of transfected THP-1 cells, the migration and invasion ability of HEC-1A cells in YKL-40-siRNA group was significantly reduced; the number of tubes in the YKL-40-siRNA group was significantly reduced, the spacing between the tubes was significantly increased, and the structure of tubes was incomplete.

conclusionSilencing the YKL-40 gene in THP-1 cells can inhibit the expression of inflammatory factors, the invasion and migration of human endometrial cancer cells and the capacity of vitro angiogenic. And YKL-40 gene as a marker of inflammation may be an effective therapeutic target for endometrial cancer.
