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 (PDAC) is one of the most frequently diagnosed cancers and the fourth leading cause of cancer-related death in the United States, suggesting that there is an urgent need to design novel strategies for achieving better treatment outcome of patients diagnosed with PDAC. Our previous study has shown that activation of Notch and NF-κB play a critical role in the development of PDAC in the compound K-Ras(G12D) and Ink4a/Arf deficient transgenic mice. However, the exact molecular mechanism by which mutated K-Ras and Ink4a/Arf deficiency contribute to progression of PDAC remains largely elusive. In the present study, we used multiple methods, such as real-time RT-PCR, Western blotting assay, and immunohistochemistry to gain further mechanistic insight. We found that the deletion of Ink4a/Arf in K-Ras(G12D) expressing mice led to high expression of PDGF-D signaling pathway in the tumor and tumor-derived cell line (RInk-1 cells). Furthermore, PDGF-D knock-down in RInk-1 cells resulted in the inhibition of pancreatosphere formation and down-regulation of EZH2, CD44, EpCAM, and vimentin. Moreover, we demonstrated that epithelial-mesenchymal transition (EMT) was induced in the compound mice, which is linked with aggressiveness of PDAC. In addition, we demonstrated that tumors from compound transgenic mice have higher expression of cancer stem cell (CSC) markers. These results suggest that the acquisition of EMT phenotype and induction of CSC characteristics could be linked with the aggressiveness of PDAC mediated in part through the activation of PDGF-D, signaling.
