Key result
Indocyanine Green-001 significantly improved left ventricular ejection fraction to 51.2% compared to 34.6% in untreated mice following sepsis induced by cecal ligation and puncture.
Why the study?
Does ICG-001 improve left ventricular function and attenuate myocardial injury in a mouse model of sepsis?
Does ICG-001 improve left ventricular function and attenuate myocardial injury in a mouse model of sepsis?
ICG-001 attenuates sepsis-induced myocardial injury and improves left ventricular function in mice by downregulating the Wnt/β-catenin signaling pathway.

OBJECTIVE: To investigate the mechanistic pathway of both indocyanine green (ICG)-001 in attenuated endotoxemia-induced cardiac depression through downregulation cardiac Wnt/ β-catenin cell signaling. MATERIALS AND METHODS: Adult (4-6 months) male Albino-Webster mice, their weights ranged from 25 to 30 g, were pretreated with ICG-001 i.p., following cecal ligation and puncture (CLP). Left ventricle (LV) function was assessed using a microcatheter system. Monocyte chemoattractant protein-1 (MCP-1) and cytokines mediators in plasma and myocardium were analyzed by enzyme-linked immunosorbent assay. Further, the cardiac Wnt protein measured by quantitative real-time polymerase chain reaction while β-catenin analysis through Western blotting procedure. The pathological changes and cells injury in the myocardium were examined using hematoxylin and eosin staining. RESULTS: CLP mice displayed worse LV function. The exaggerated cardiac depression in CLP mice was associated with higher levels of MCP-1 and cytokines in plasma and myocardium together with greater cardiac levels of cardiac troponin-I and Wnt/β-catenin. Neutralization of sepsis by either ICG-001resulted in improved LV function and reductions in inflammatory mediators. CONCLUSION: Taken together, these data showed that ICG-001 improved LV function following sepsis through downregulation of Wnt/β-catenin and serve as a potential mechanistic pathway ICG-001 in therapeutic cardiac endotoxemia in animal model.

Yousif et al. (2017) studied Sepsis-induced myocardial injury (n=32). Indocyanine Green-001 (ICG-001) vs. Cecal ligation and puncture (CLP) without treatment / Vehicle was evaluated on Left ventricular ejection fraction (%) (null, 95% CI null, p=<0.05). Indocyanine Green-001 significantly improved left ventricular ejection fraction to 51.2% compared to 34.6% in untreated mice following sepsis induced by cecal ligation and puncture.
