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 epidermal growth factor receptor (EGFR) was among the first receptor tyrosine kinases (RTKs) shown to be activated by ligand-induced dimerization. Structural studies explain how ligand binding induces the dimerization of EGFR's extracellular region. Unlike other RTKs, EGFR's intracellular tyrosine kinase domain (TKD) is activated allosterically in an asymmetric dimer that is observed crystallographically, but not in cryo-EM studies of intact EGFR. Here, we show that this asymmetric TKD dimer forms only transiently - explaining its lack of definition by cryo-EM. By engineering an asymmetric TKD dimer and studying a TKD-duplicated lung cancer EGFR variant, we show that TKD dimerization increases kinase activity by several hundred-fold. We were also able to stabilize and visualize discrete asymmetric EGFR TKD dimers at high resolution using cryo-EM. Our findings argue that oncogenic mutations activate EGFR primarily by promoting TKD dimerization, and suggest that the transient nature of EGFR TKD dimers may allow biased EGFR signaling.
