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

Phosphatidylinositol-4,5-bisphosphate [PI(4,5)P(2) or PIP(2)] is a direct modulator of a diverse array of proteins in eukaryotic cells. The functional integrity of transmembrane proteins, such as ion channels and transporters, is critically dependent on specific interactions with PIP(2) and other phosphoinositides. Here, we report a novel requirement for PIP(2) in the activation of the epidermal growth factor receptor (EGFR). Down-regulation of PIP(2) levels either via pharmacological inhibition of PI kinase activity, or via manipulation of the levels of the lipid kinase PIP5K1α and the lipid phosphatase synaptojanin, reduced EGFR tyrosine phosphorylation, whereas up-regulation of PIP(2) levels via overexpression of PIP5K1α had the opposite effect. A cluster of positively charged residues in the juxtamembrane domain (basic JD) of EGFR is likely to mediate binding of EGFR to PIP(2) and PIP(2)-dependent regulation of EGFR activation. A peptide mimicking the EGFR juxtamembrane domain that was assayed by surface plasmon resonance displayed strong binding to PIP(2). Neutralization of positively charged amino acids abolished EGFR/PIP(2) interaction in the context of this peptide and down-regulated epidermal growth factor (EGF)-induced EGFR auto-phosphorylation and EGF-induced EGFR signaling to ion channels in the context of the full-length receptor. These results suggest that EGFR activation and downstream signaling depend on interactions of EGFR with PIP(2) and point to the basic JD's critical involvement in these interactions. The addition of this very different class of membrane proteins to ion channels and transporters suggests that PIP(2) may serve as a general modulator of the activity of many diverse eukaryotic transmembrane proteins through their basic JDs.
