The Gβ5 protein regulates sensitivity to TRAIL-induced cell death in colon carcinoma.
Article in Oncogene, 2015. 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
Aberrant signaling via G protein-coupled receptors (GPCRs) is implicated in numerous diseases including colon cancer. The heterotrimeric G proteins transduce signals from GPCRs to various effectors. So far, the G protein subunit Gβ5 has not been studied in the context of cancer. Here we demonstrate that Gβ5 protects colon carcinoma cells from apoptosis induced by the death ligand TRAIL via different routes. The Gβ5 protein (i) causes a decrease in the cell surface expression of the TRAIL-R2 death receptor, (ii) induces the expression of the anti-apoptotic protein XIAP and (iii) activates the NF-κB signaling pathway. The intrinsic resistance to TRAIL-triggered apoptosis of colon cancer cells is overcome by antagonization of Gβ5. Based on these results, targeting of G proteins emerges as a novel therapeutic approach in the experimental treatment of colon cancer.
