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

Pancreatic ductal adenocarcinoma (PDA) is an aggressive metastatic cancer with a very low survival rate. This tumor is hypovascularized and characterized by severe hypoxic regions, yet these regions are not impeded by the oxidative stress in their microenvironment. PDA's high resilience raises the need to find new effective therapeutic targets. This study investigated the suitability of methionine aminopeptidase 2 (MetAp2), a metallopeptidase known to play an important role in tumor progression, as a new target for treating PDA. In our examination of patient-derived PDA tissues, we found that MetAp2 is highly expressed in metastatic regions compared with primary sites. At the cellular level, we found that the basal expression levels of MetAp2 in pancreatic cancer cells were higher than its levels in endothelial cells. Pancreatic cancer cells showed a significant suppression of proliferation in a dose-dependent manner upon exposure to TNP-470, a selective MetAp2 inhibitor. In addition, a significant reduction in glutathione (GSH) levels - known for its importance in alleviating oxidative stress - was detected in all treated cells, suggesting a possible anti-cancer activity mechanism that would be feasible for treating highly hypoxic PDA tumors. Furthermore, in an orthotopic pancreatic cancer murine model, systemic oral treatment with a MetAp2 inhibitor significantly reduced tumors' growth. Taken together, our findings indicate that MetAp2 enhances tumor sensitivity to hypoxia and may provide an effective target for treating hypoxic tumors with high expression levels of MetAp2.
