A Synthetic Peptide AWRK6 Alleviates Lipopolysaccharide-Induced Liver Injury.
Article in International journal of molecular sciences, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
During lipopolysaccharide (LPS)-induced sepsis, the liver plays central roles in toxins phagocytosis and clearance to protect the whole body. The liver cells were constantly irritated by LPS which leads to liver injury. While most anti-LPS agents showed little clinical activity against LPS-induced liver injury. Here, the protective effects of the synthetic peptide AWRK6 against LPS-induced liver injury have been investigated in vivo and in vitro. In mice liver homogenate, LPS administration elevated ALT (alanine aminotransferase), iNOS (inducible nitric oxide synthase) and repressed SOD (superoxide dismutase) activities and these changes were remarkably reversed by AWRK6. Histologically, AWRK6 effectively alleviated the histological changes and repressed LPS-induced neutrophils infiltration. By TUNEL assay on liver sections, AWRK6 was proven to inhibit apoptosis induced by LPS in mice livers, which was also verified by the protein levels of cleaved-caspase 9, Bax and Bcl-2. In addition, by in vitro study using HepG2 cells, AWRK6 was found to recover the LPS-reduced cell viability and reduce LPS-induced apoptosis. For mechanisms, AWRK6 was demonstrated to alleviate the LPS-induced phosphorylation of ERK, JNK and p38 MAPK, indicating the involvement of MAPKs in the protection of AWRK6 against liver injury. In summary, we have found the synthetic peptide AWRK6 as a promising novel agent for LPS-induced liver injury, by inhibiting cell apoptosis through MAPK signaling pathways, which might bring new strategies for the treatment of acute and chronic liver injuries.
