Sclareolide enhances gemcitabine‑induced cell death through mediating the NICD and Gli1 pathways in gemcitabine‑resistant human pancreatic cancer.
Article in Molecular medicine reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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.
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 cancer is a type of cancer, which rapidly develops resistance to chemotherapy. Gemcitabine is the treatment used clinically, however, gemcitabine resistance leads to limited efficacy and patient survival rates of only a few months following diagnosis. The aim of the present study was to investigate the mechanisms underlying gemcitabine resistance in pancreatic cancer and to select targeted agents combined with gemcitabine to promote the treatment of pancreatic cancer. Panc‑1 and ASPC‑1 human pancreatic cancer cells (HPCCs) were used to establish the experimental model, and HPCCs were exposed to gemcitabine of serially increased concentrations to generate gemcitabine‑resistant cells (GR‑HPCCs). The anticancer effect of gemcitabine combined with sclareolide was then assessed. Epithelial to mesenchymal transition (EMT), human equilibrative nucleoside transporter 1 (hENT1) and ribonucleoside diphosphate reductase 1 (RRM1) were detected in the HPCCs and GR‑HPCCs, and the mechanisms were investigated. Sclareolide resensitized the GR‑HPCCs to gemcitabine. The expression levels of hENT1 and RRM1 were lower and higher, respectively, in GR‑HPCCs, compared with HPCCs. Sclareolide upregulated hENT1, downregulated RRM1 and inhibited gemcitabine‑induced EMT through the TWIST1/Slug pathway in the GR‑HPCCs. In addition, sclareolide mediated the NOTCH 1 intracellular cytoplasmic domain (NICD)/glioma‑associated oncogene 1 (Gli1) pathway, which triggered TWIST1/Slug‑hENT1/RRM1 signaling and resensitized GR‑HPCCs to gemcitabine. Finally, sclareolide resensitized GR‑HPCCs to gemcitabine through inducing apoptosis; in vivo, the co‑administraion of sclareolide and gemcitabine effectively suppressed tumor growth. Sclareolide may be a novel agent in combination with gemcitabine for the treatment of gemcitabine‑resistant pancreatic cancer, which resensitizes GR‑HPCCs to gemcitabine through mediating NICD and Gli1.
