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

backgroundAlthough programmed cell death-ligand 1 (PD-L1) plays a well-known function in immune checkpoint response by interacting with programmed cell death-1 (PD-1), the cell-intrinsic role of PD-L1 in tumors is still unclear. Here, we explored the molecular regulatory mechanism of PD-L1 in the progression and metastasis of ovarian cancer.

methodsImmunohistochemistry of benign tissues and ovarian cancer samples was performed, followed by migration, invasion, and angiogenesis assays in PD-L1-knockdown ovarian cancer cells. Immunoprecipitation, mass spectrometry, and chromatin immunoprecipitation were conducted along with zebrafish and mouse experiments to explore the specific functions and mechanisms of PD-L1 in ovarian cancer.

resultsOur results showed that PD-L1 induced angiogenesis, which further promoted cell migration and invasion in vitro and in vivo of ovarian cancer. Mechanistically, PD-L1 was identified to directly interact with vascular endothelial growth factor receptor-2 (VEGFR2) and then activated the FAK/AKT pathway, which further induced angiogenesis and tumor progression, leading to poor prognosis of ovarian cancer patients. Meanwhile, PD-L1 was found to be regulated by the oncogenic transcription factor c-JUN at the transcriptional level, which enhanced the expression of PD-L1 in ovarian cancer. Furthermore, we demonstrated that PD-L1 inhibitor durvalumab, combined with the antiangiogenic drug, apatinib, could enhance the effect of anti-angiogenesis and the inhibition of cell migration and invasion.

conclusionOur results demonstrated that PD-L1 promoted the angiogenesis and metastasis of ovarian cancer by participating in the c-JUN/VEGFR2 signaling axis, suggesting that the combination of PD-L1 inhibitor and antiangiogenic drugs may be considered as a potential therapeutic approach for ovarian cancer patients.
