Hello Guys and gals,

been lurking long enough, trying to learn and apply what i could.
Now starting to contribute my share:


Prevention of arachidonic acid‑induced liver injury by controlling oxidative stress‑mediated transglutaminase activation with garlic extracts

Abstract
Garlic and its sulfur constituents have numerous biological functions, such as antioxidant, anti‑inflammatory, anti‑microbial, anticancer, antidiabetic and cardioprotective effects. Fatty liver diseases, such as non‑alcoholic steatohepatitis, which is characterized by the accumulation of lipids and oxidative stress in hepatocytes and continual liver damage, has attracted much attention, and it is believed that it will become the leading etiology of liver cancer. We have previously reported that the growth‑suppressive effects of arachidonic acid (AA), an unsaturated fatty acid known to be a pro‑inflammatory precursor, is accompanied by the production of reactive oxygen species followed by the nuclear accumulation and activation of the protein crosslinking enzyme, transglutaminase (TG)2. In this study, we examined the potential role of garlic extracts in preventing the growth‑suppressive effects of AA on human hepatic cells. We also aimed to provide a mechanistic insight regarding the association between the hepatoprotective effects of garlic extract and the inhibition of the TG‑related crosslinking of nuclear proteins, which is not associated with hepatic lipid partitioning mediated by stearoyl‑CoA desaturase‑1. Given the critical roles of unsaturated fatty acids in the regulation of cancer cell stemness and immune surveillance in the context of chronic injury, we propose that garlic extracts may serve as a therapeutic option for the prevention of chronic liver injury and inflammation, as well as for the prevention of the carcinogenesis of fatty livers.
