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

Constitutive secretion of heparan sulphate proteoglycans (HSPGs) was stimulated in human hepatoma HepG2 cells by phorbol 12-myristate 13-acetate (PMA) and inhibited by calphostin C, a specific inhibitor of protein kinase C (PKC). To delineate more closely the site of PKC action, the packaging in vitro of 35SO4-labelled HSPGs into transport vesicles was investigated. Formation of transport vesicles at the trans-Golgi network was stimulated by PMA and inhibited by calphostin C or Ro 31-8220 by using a post-nuclear supernatant. Treatment of either isolated Golgi-enriched membranes or cytosolic proteins with calphostin C provided evidence that membrane-bound PKC forms strongly supported vesicle formation, whereas cytosolic PKC forms showed a marginal effect. The PKC isoforms PKC-alpha and PKC-zeta were attached to highly purified Golgi membranes, as shown by Western blotting. Both isoforms were localized by confocal immunofluorescence microscopy in the Golgi area of HepG2 cells. Immunoelectron microscopy of ultrathin cryosections of HepG2 cells showed that PKC-zeta predominantly attaches to the trans-Golgi region, whereas PKC-alpha binds to the cis- and trans-Golgi area.
