Cathelicidin-WA Protects Against LPS-Induced Gut Damage Through Enhancing Survival and Function of Intestinal Stem Cells.
Article in Frontiers in cell and developmental biology, 2021. 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
Preservation of intestinal stem cells (ISCs) plays a critical role in initiating epithelial regeneration after intestinal injury. Cathelicidin peptides have been shown to participate in regulating intestinal damage repair. However, it is not known how exactly Cathelicidin-WA (CWA) exert its function after tissue damage. Using a gut injury model in mice involving Lipopolysaccharide (LPS), we observed that CWA administration significantly improved intestinal barrier function, preserved ISCs survival, and augmented ISCs viability within the small intestine (SI) under LPS treatment. In addition, CWA administration effectively prevented proliferation stops and promoted the growth of isolated crypts. Mechanistically, our results show that the appearance of γH2AX was accompanied by weakened expression of SETDB1, a gene that has been reported to safeguard genome stability. Notably, we found that CWA significantly rescued the decreased expression of SETDB1 and reduced DNA damage after LPS treatment. Taken together, CWA could protect against LPS-induced gut damage through enhancing ISCs survival and function. Our results suggest that CWA may become an effective therapeutic regulator to treat intestinal diseases and infections.
