Pyrroloquinoline-Quinone Suppresses Liver Fibrogenesis in Mice

Abstract: Liver fibrosis represents the consequences of a sustained wound healing response to chronic liver injuries, and its progression toward cirrhosis is the major cause of liver-related morbidity and mortality worldwide. However, anti-fibrotic treatment remains an unconquered area for drug development. Accumulating evidence indicate that oxidative stress plays a critical role in liver fibrogenesis. In this study, we found that PQQ, a natural anti-oxidant present in a wide variety of human foods, exerted potent anti… Show more

“…It is a pathological process that often leads to hepatocellular carcinoma (Iwaisako, Brenner, & Kisseleva, 2012), which is one of the major causes of morbidity and mortality worldwide (Jia et al, 2015). Carbon tetrachloride (CCl4) is commonly used to induce liver injury, and it has been shown that the CCl4-induced liver oxidative damage responses in animals are similar to those in humans (Hsu et al, 2008).…”

“…Six pqq genes and one GDh gene has been identified in R. aquatilis strains, found necessary for biosynthesis of the Antibacterial substqnceABS, as biocontrol of crown gall disease [67]. The (GDHm) is a 86 kDa [68] double mutants of PQQ are more sensitive and ndvB stimulates antibiotic resistance by sequestration of drugs in cyclic glucans and ethanol oxidation genes activates antibiotic resistance ( Figure 6) [69].…”

“…As a free radical scavenger, PQQ has been reported to increase nerve growth factor (NGF) concentrations in astrocytes and it inhibits melanin production in melanoma cells . In animal models, PQQ has been reported to have a cardioprotective effect, as well as to prevent hepatic alcohol damage (Jia et al, 2015).…”

“…It has been reported that PQQ is a potent antioxidant (50-100 times more effective than ascorbic acid) (Rucker et al, 2009). It has been also reported that PQQ can function as a protector in cardiac lesions, prevents liver injury by eliminating free radicals, stimulates astrocytes and inhibits the generation of melanocytes in melanoma (Akagawa et al, 2016;Feng et al, 2014;Jia et al, 2015;Murase et al, 1993;Sato and Toriyama, 2009;Tao et al, 2007). In animal models, it has been shown that when PQQ is added to the diet (300 μg/kg body weight), reproduction and neonatal rates in rats and mice were increased (Harris et al, 2013).…”
