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

A syngeneic mouse model bearing a transplanted tumor is indispensable for the evaluation of the efficacy of immune checkpoint inhibitors (ICIs). However, few syngeneic mouse models of liver cancer are available. We established liver tumor cell lines (MHCF1 and MHCF5) from hepatitis C virus transgenic mice fed an atherogenic high-fat diet. MHCF1 and MHCF5 were successfully transplanted into the subcutaneous space of syngeneic C57BL/6 mice, in addition, they efficiently developed orthotopic tumors in the liver of syngeneic C57BL/6 mice. MHCF5 grew rapidly and showed a more malignant phenotype compared with MHCF1. Histologically, MHCF1-derived tumors were a combined type of hepatocellular carcinoma and MHCF5-derived tumors showed a sarcomatous morphology. Interestingly, MHCF1 and MHCF5 showed different sensitivity against an anti-PD1 antibody and MHCF5-derived tumors were resistant to this antibody. CD8 T cells infiltrated the MHCF1-derived tumors, but no CD8 T cells were found within the MHCF5-derived tumors. Gene expression profiling and whole-exon sequencing revealed that MHCF5 displayed the features of an activated cancer stem cell-like signature of sonic hedgehog and Wnt signaling. Therefore, these cell lines could be useful for the identification of new biomarkers and molecular mechanisms of ICI resistance and the development of new drugs against liver cancer.
