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

Assembly of clathrin-coated pits and their maturation into coated vesicles requires coordinated interactions between specific lipids and several structural and regulatory proteins. In the presence of primary alcohols, phospholipase D generates phosphatidylalcohols instead of PA, reducing stimulation of phosphatidyl inositol 5-kinase (PI5K) and hence decreasing formation of phosphoinositide-4,5-biphosphate (PIP(2)). Using live-cell imaging, we have shown that acute treatment of cells with 1-butanol or other small primary alcohols induces rapid disassembly of coated pits at the plasma membrane and blocks appearance of new ones. Addition of exogenous PIP(2) reverses this effect. Coated pits and vesicles reappear synchronously upon removal of 1-butanol; we have used this synchrony to assess the role of actin in coated vesicle assembly. Prolonged inhibition of actin polymerization by latrunculin A or cytochalasin D reduced by approximately 50% the frequency of coated pit formation without affecting maturation into coated vesicles. As in control cells, removal of 1-butanol in the continued presence of an actin depolymerizer led to synchronous appearance of new pits, which matured normally. Thus, remodeling of the actin cytoskeleton is not essential for clathrin-coated vesicle assembly but may indirectly affect the nucleation of clathrin-coated pits.
