Volasertib Enhances Sensitivity to TRAIL in Renal Carcinoma Caki Cells through Downregulation of c-FLIP Expression.
Article in International journal of molecular sciences, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Polo-like kinase 1 (PLK1) plays major roles in cell cycle control and DNA damage response. Therefore, PLK1 has been investigated as a target for cancer therapy. Volasertib is the second-in class dihydropteridinone derivate that is a specific PLK1 inhibitor. In this study, we examined that combining PLK1 inhibitor with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) would have an additive and synergistic effect on induction of apoptosis in cancer cells. We found that volasertib alone and TRAIL alone had no effect on apoptosis, but the combined treatment of volasertib and TRAIL markedly induced apoptosis in Caki (renal carcinoma), A498 (renal carcinoma) and A549 (lung carcinoma) cells, but not in normal cells (human skin fibroblast cells and mesangial cells). Combined treatment induced accumulation of sub-G1 phase, DNA fragmentation, cleavage of poly (ADP-ribose) polymerase (PARP) and activation of caspase 3 activity in Caki cells. Interestingly, combined treatment induced downregulation of cellular-FLICE-inhibitory protein (c-FLIP) expression and ectopic expression of c-FLIP markedly blocked combined treatment-induced apoptosis. Therefore, this study demonstrates that volasertib may sensitize TRAIL-induced apoptosis in Caki cells via downregulation of c-FLIP.
