TRAIL and interferon-alpha act synergistically to induce renal cell carcinoma apoptosis.
Article in The Journal of urology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeDespite modern targeted therapy metastatic renal cell carcinoma remains a deadly disease. Interferon-alpha (Calbiochem(R)) is currently used to treat this condition, mainly combined with the targeted anti-vascular endothelial growth factor antibody bevacizumab. TRAIL (Apo2 ligand/tumor necrosis factor related apoptosis inducing ligand) (Calbiochem) is a novel antineoplastic agent now in early phase clinical trials. Interferon-alpha and TRAIL can act synergistically to kill cancer cells but to our knowledge this has never been tested in the context of renal cell carcinoma. We hypothesized that TRAIL and interferon-alpha could synergistically induce apoptosis in renal cell carcinoma cells. MATERIALS AND
methodsWe treated renal cell carcinoma cell lines with recombinant TRAIL and/or interferon-alpha. Viability and apoptosis were assessed by MTS assay, flow cytometry and Western blot. Synergy was confirmed by isobologram. Interferon-alpha induced changes in renal cell carcinoma cell signaling were assessed by Western blot, flow cytometry and enzyme-linked immunosorbent assay.
resultsTRAIL and interferon-alpha acted synergistically to increase apoptotic cell death in renal cell carcinoma cells. Interferon-alpha treatment altered the ability of cells to activate extracellular signal-regulated kinase while inhibiting extracellular signal-regulated kinase with UO126 abrogated TRAIL and interferon-alpha apoptotic synergy. Interferon-alpha did not induce changes in TRAIL or death receptor expression, or change other known mediators of the intrinsic and extrinsic apoptotic cascade in the cells.
conclusionsTRAIL plus interferon-alpha synergistically induces apoptosis in renal cell carcinoma cells, which is due at least in part to interferon-alpha mediated changes in extracellular signal-regulated kinase activation. TRAIL and interferon-alpha combination therapy may be a novel approach to advanced renal cell carcinoma that warrants further testing in vivo.
