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

The role of heat shock protein 70 (HSP70) in apoptosis of human retinal pigment epithelial cells (ARPE-19) induced by 4-hydroxy-2-nonenal (4-HNE) was explored. Different concentrations of 4-HNE were used to stimulate ARPE-19 cells, and apoptosis was measured by flow cytometry. The expression of apoptotic-related proteins, HSP70, X-linked inhibitor-of-apoptosis (XIAP), Bcl-2, and Bax were quantified by Western blotting. HSP70 and XIAP overexpression plasmids, or their corresponding siRNAs were transfected into ARPE-19 cells using Lipofectamine™ 2000. Co-immunoprecipitation and Western blotting were used to detect the effect of 4-HNE on the expression of HSP70 and the binding level between 4-HNE and HSP70. The results showed that 4-HNE induced late apoptosis in ARPE-19 cells, accompanied by elevated levels of 4-HNE-modified HSP70, but it did not affect HSP70 protein expression. 4-HNE-modified HSP70 down-regulated the expression of the apoptosis inhibitory protein XIAP. Overexpression of HSP70 or XIAP inhibited 4-HNE-induced apoptosis of ARPE-19 cells. It was suggested that 4-HNE could promote XIAP degradation by modification of HSP70 to induce late apoptosis of human retinal pigment epithelial cells.
