Tributyltin (TBT) induces ultra-rapid caspase activation independent of apoptosome formation in human platelets.

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
Activation of caspases has been demonstrated to be involved in thrombocytopenia and prolonged storage of platelet concentrates. Platelets represent enucleate cells that comprise all elements of the mitochondrial apoptosis pathway. However, no apoptotic stimuli capable of activating the endogenous caspase cascade have been identified so far. Using tributyltin (TBT) we could identify a compound that is capable of activating caspase-9 and -3 in platelets. Recent studies implicate that TBT induces apoptosis via the mitochondrial signaling pathway that is characterized by the formation of a high-molecular-weight complex (apoptosome) containing the adapter protein Apaf-1 and active caspase-9. Interestingly, addition of TBT induced the activation of caspase-9 in an ultra-rapid kinetic within the first 2 min. In addition, size exclusion chromatography revealed that TBT-mediated processing of caspase-9 occurs in the absence of the apoptosome. Thus, these data implicate that TBT induces the activation of caspase-9 by a mechanism not involving the formation of the apoptosome.
