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

Endothelial barrier disruption plays a key role in the pathophysiology of heat stroke (HS). Knockout of DNAJA1 (DNAJA1‑KO) is thought to be protective against HS based on a genome‑wide CRISPR‑Cas9 screen experiment. The present study aimed to illustrate the function of DNAJA1‑KO against HS in human umbilical vein endothelial cells. DNAJA1‑KO cells were infected using a lentivirus to investigate the role of DNAJA1‑KO in HS‑induced endothelial barrier disruption. It was shown that DNAJA1‑KO could ameliorate decreased cell viability and increased cell injury, according to the results of Cell Counting Kit‑8 and lactate dehydrogenase assays. Moreover, HS‑induced endothelial cell apoptosis was inhibited by DNAJA1‑KO, as indicated by Annexin V‑FITC/PI staining and cleaved‑caspase‑3 expression using flow cytometry and western blotting, respectively. Furthermore, the endothelial barrier function, as measured by transepithelial electrical resistance and FITC‑Dextran, was sustained during HS. DNAJA1‑KO was not found to have a significant effect on the expression and distribution of cell junction proteins under normal conditions without HS. However, DNAJA1‑KO could effectively protect the HS‑induced decrease in the expression and distribution of cell junction proteins, including zonula occludens‑1, claudin‑5, junctional adhesion molecule A and occludin. A total of 4,394 proteins were identified using proteomic analysis, of which 102 differentially expressed proteins (DEPs) were activated in HS‑induced wild‑type cells and inhibited by DNAJA1‑KO. DEPs were investigated by enrichment analysis, which demonstrated significant enrichment in the 'calcium signaling pathway' and associations with vascular‑barrier regulation. Furthermore, the 'myosin light‑chain kinase (MLCK)‑MLC signaling pathway' was proven to be activated by HS and inhibited by DNAJA1‑KO, as expected. Moreover, DNAJA1‑KO mice and a HS mouse model were established to demonstrate the protective effects on endothelial barrier
