Dose-dependent effects of selenite (Se(4+)) on arsenite (As(3+))-induced apoptosis and differentiation in acute promyelocytic leukemia cells.
Article in Cell death & disease, 2015. 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
To enhance the therapeutic effects and decrease the adverse effects of arsenic on the treatment of acute promyelocytic leukemia, we investigated the co-effects of selenite (Se(4+)) and arsenite (As(3+)) on the apoptosis and differentiation of NB4 cells and primary APL cells. A 1.0-μM concentration of Se(4+) prevented the cells from undergoing As(3+)-induced apoptosis by inhibiting As(3+) uptake, eliminating As(3+)-generated reactive oxygen species, and repressing the mitochondria-mediated intrinsic apoptosis pathway. However, 4.0 μM Se(4+) exerted synergistic effects with As(3+) on cell apoptosis by promoting As(3+) uptake, downregulating nuclear factor-кB, and activating caspase-3. In addition to apoptosis, 1.0 and 3.2 μM Se(4+) showed contrasting effects on As(3+)-induced differentiation in NB4 cells and primary APL cells. The 3.2 μM Se(4+) enhanced As(3+)-induced differentiation by promoting the degradation of promyelocytic leukemia protein-retinoic acid receptor-α (PML-RARα) oncoprotein, but 1.0 μM Se(4+) did not have this effect. Based on mechanistic studies, Se(4+), which is similar to As(3+), might bind directly to Zn(2+)-binding sites of the PML RING domain, thus controlling the fate of PML-RARα oncoprotein.
