1 · What the graph read from it

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.

2 · The registry

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 B-cell lymphoma 2 (BCL2) proteins are a class of apoptosis regulators that control the release of apoptogenic factors from mitochondria. Under normal physiological conditions, apoptosis is inhibited through the actions of anti-apoptotic (repressor) BCL2 proteins that bind semi-indiscriminately to the helical BH3 domains of pro-apoptotic (effector) BCL2 proteins. In this work, we developed a series of BH3 domain mimetics by grafting residues from the effector BCL2 protein Bax onto the α-helix of scyllatoxin (ScTx). These so-called "ScTx-Bax" constructs were then used to gain insight into the physicochemical nature of repressor/effector BCL2 interactions. Specifically, we utilized competitive binding and isothermal titration calorimetry (ITC) to investigate the inhibitory potential and binding thermodynamics of ScTx-Bax structural variants that target the repressor protein Bcl-2 (proper) in vitro. Our data show that ScTx-Bax mimetics compete with isolated Bax BH3 domain peptides for Bcl-2 with IC
