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

Nature killer (NK) cell plays a critical role in cancer immunosurveillance and is considered a potent immunotherapeutic tool for many cancers, including pancreatic ductal adenocarcinomas (PDACs). Increasing evidence suggests that cancer occurs with systemic immune perturbations. However, the effects of PDAC tumor burden on systemic NK cells remain poorly understood. PDAC tumor-bearing mice display decreased frequency and dysfunction of NKs the spleens. We identified an increase in Gr-1+ myeloid cells within the spleens, which negatively impacts both endogenous and adoptively transferred NK cell frequency and function. Apolipoprotein E (ApoE), a lipid metabolism regulator, is upregulated in Gr-1+ myeloid cells of tumor-bearing mice, promoting lipid oxidation and reactive oxygen species (ROS) generation. Genetic knockout of Apoe in Gr-1+ myeloid cells abrogate their suppressive effects on NK cell function. Furthermore, treatment with lipid metabolism inhibitors restores endogenous and adoptively transferred NKs' effector function in the spleens and tumor microenvironment. These studies underscore the importance of understanding preexisting systemic alterations in PDAC patients before applying NK cell-based immunotherapies.
