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

Ptd(4,5)P(2) is thought to promote and organize a wide range of cellular functions, including vesicular membrane traffic and cytoskeletal dynamics, by recruiting functional protein complexes to restricted locations in cellular membranes. However, little is known about the distribution of PtdIns(4,5)P(2) in the cell at high resolution. We have used the pleckstrin homology (PH) domain of phospholipase delta(1) (PLCdelta(1)), narrowly specific for PtdIns(4,5)P(2), to map the distribution of the lipid in astrocytoma and A431 cells. We applied the glutathione S-transferase-tagged PLCdelta(1) PH domain (PLCdelta(1)PH-GST) in an on-section labelling approach which avoids transfection procedures. Here we demonstrate PtdIns(4,5)P(2) labelling in the plasma membrane, and also in intracellular membranes, including Golgi (mainly stack), endosomes and endoplasmic reticulum, as well as in electron-dense structures within the nucleus. At the plasma membrane, labelling was more concentrated over lamellipodia, but not in caveolae, which contained less than 10% of the total cell-surface labelling. A dramatic decrease in signal over labelled compartments was observed on preincubation with the cognate headgroup [Ins(1,4,5)P(3)], and plasma-membrane labelling was substantially decreased after stimulation with thrombin-receptor-activating peptide (SFLLRN in the one-letter amino acid code), a treatment which markedly diminishes PtdIns(4,5)P(2) levels. Thus we have developed a highly selective method for mapping the PtdIns(4,5)P(2) distribution within cells at high resolution, and our data provide direct evidence for this lipid at key functional locations.
