PET imaging of in vivo caspase-3/7 activity following myocardial ischemia-reperfusion injury with the radiolabeled isatin sulfonamide analogue [(18)F]WC-4-116.
Article in American journal of nuclear medicine and molecular imaging, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The utility of [(18)F]WC-4-116, a PET tracer for imaging caspase-3 activation, was evaluated in an animal model of myocardial apoptosis. [(18)F]WC-4-116 was injected into rats at 3 hours after a 30 min period of ischemia induced by temporary occlusion of the left anterior descending coronary artery in Sprague-Dawley rats. [(18)F]WC-4-116 uptake was quantified by 1) autoradiography, 2) microPET imaging studies, and 3) post-PET biodistribution studies. MicroPET imaging also assessed uptake of the non-caspase-3-targeted tracer [(18)F]ICMT-18 at 3 hours postischemia. Enzyme assays and Western blotting assessed caspase-3 activation in both at-risk and not-at-risk regions. Caspase-3 enzyme activity increased in the at-risk but not in the not-at-risk myocardium. Quantitative autoradiographic analysis of [(18)F]WC-4-116 demonstrated nearly 2-fold higher uptake in the ischemia-reperfusion (IR) versus sham animals. [(18)F]WC-4-116 microPET imaging studies demonstrated that the IR animals was similarly elevated in relation to sham. [(18)F]ICMT-18 uptake did not increase in at-risk myocardium despite evidence of caspase-3 activation. Biodistribution studies with [(18)F]WC-4-116 confirmed the microPET findings. These data indicate that the caspase-3-PET tracer [(18)F]WC-4-116 can noninvasively image in vivo caspase activity during myocardial apoptosis and may be useful for clinical imaging in humans.
