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

Protein phosphatase 2A (PP2A) is one of the major protein serine/threonine phosphatases (PPPs) with regulatory effects on several cellular processes, but its role and function in Adriamycin (ADR)-treated podocytes injury needs to be further explored. Mice podocytes were treated with ADR and PP2A inhibitor (okadaic acid, OA). After transfection, cell apoptosis was detected by flow cytometry. Expressions of podocytes injury-, apoptosis- and epithelial-to-mesenchymal transition (EMT)- and JNK-interacting protein 4/p38-Mitogen-Activated Protein Kinase (JIP4/p38-MAPK) pathway-related factors were measured using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot as needed. Interaction between PP2A and JIP4/MAPK pathway was confirmed using co-immunoprecipitation (Co-Ip) assay. In podocytes, ADR inhibited PP2A, Nephrin and Wilms' tumor (WT) 1 expressions yet upregulated apoptosis and Desmin expression, and suppressing PP2A expressionenhanced the effects. PP2A overexpression reversed the effects of ADR on PP2A and podocyte injury-related factors expressions and apoptosis of podocytes. JIP4 was the candidate gene interacting with both PP2A and p38-MAPK pathway, and PP2A overexpression alleviated the effects of ADR on p38-MAPK pathway-related factors expressions. Additionally, in ADR-treated podocytes, PP2A suppression enhanced the effects of ADR, yet silencing of JIP4 reversed the effects of PP2A suppression on regulating p38-MAPK pathway-, apoptosis- and EMT-related factors expressions and apoptosis, with upregulations of B-cell lymphoma-2 (Bcl-2) and E-cadherin and down-regulations of Bcl-2 associated protein X (Bax), cleaved (C)-casapse-3, N-cadherin, Vimentin and Snail. PP2A protects ADR-treated podocytes against injury and EMT by suppressing JIP4/p38-MAPK pathway, showing their interaction in podocytes.
