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

Scinderin, a novel Ca2+-activated actin filament-severing protein, has been purified to homogeneity from bovine adrenal medulla using a combination of several chromatographic procedures. The protein has an apparent mol. wt of 79,600 +/- 450 daltons, three isoforms (pIs 6.0, 6.1 and 6.2) and two Ca2+ binding sites (Kd 5.85 x 10(-7) M, Bmax 0.81 mol Ca2+/mol protein and Kd 2.85 x 10(-6) M, Bmax 1.87 mol Ca2+/mol protein). Scinderin interacts with F-actin in the presence of Ca2+ and produces a decrease in the viscosity of actin gels as a result of F-actin filament severing as demonstrated by electron microscopy. Scinderin is a structurally different protein from chromaffin cell gelsolin, another actin filament-severing protein described. Scinderin and gelsolin have different mol. wts, isoelectric points, amino acid composition and yield different peptide maps after limited proteolytic digestion by either Staphylococcus V8 protease or chymotrypsin. Moreover, scinderin antibodies do not cross-react with gelsolin and gelsolin antibodies fail to recognize scinderin. Immunofluorescence with anti-scinderin demonstrated that this protein is mainly localized in the subplasmalemma region of the chromaffin cell. Immunoblotting tests with the same antibodies indicated that scinderin is also expressed in brain and anterior as well as posterior pituitary. Presence of scinderin and gelsolin, two Ca2+-dependent actin filament-severing proteins in the same tissue, suggests the possibility of synergistic functions by the two proteins in the control of cellular actin filament networks. Alternatively, the actin filament-severing activity of the two proteins might be under the control of different transduction and modulating influences.
