XO generates ROS during the oxidation of hypoxanthine or xanthine [32], and Ohta et al [33] suggested

that the xanthine–XO system in the gastric mucosal tissue participates in the progression of gastric mucosal lesion. In the present study, increased MPO activity—an index of neutrophil infiltration—of the gastric lesion control group was reduced, and ROS-related parameters such as MDA content and XO activity were normalized by ginsenoside Re administration. From the present study, it seems likely that administration of ginsenoside Re exerts a preventive effect on the progression of C48/80-induced acute gastric mucosal lesions by protecting the gastric mucosal barrier and tissue against the attack of ROS derived from infiltrated neutrophils and the xanthine–XO system Ceritinib chemical structure through preservation of gastric mucus. The protein encoded by the Bcl2 gene is a regulator of programmed cell death and apoptosis. The cell survival-promoting activity of this protein is contrary to the cell death-promoting activity of Bax, a homologous protein that forms heterodimers with Bcl2 and accelerates rates of cell death [34]. The

expression of Bax is upregulated by the response of the cell to stress [35]. Bax protein significantly increased 3 h after hypoxic–ischemic brain injury in neonatal brain tissue [36] and it increased in gastric mucosa after ischemia–reperfusion damage [37]. In the present results, the predominant increase of Bax expression was discovered after C48/80-induced acute gastritis. We have Epigenetics Compound Library nmr observed that the increased Bax expression by C48/80 treatment was attenuated when ginsenoside Re was administered. In contrast to Bax, Bcl2 expression decreased after C48/80 induced acute gastritis and ginsenoside Re attenuated the diminution. In Western blotting analysis, the Bax/Bcl2 ratio result also confirmed the protective effects of ginsenoside Re on C48/80-induced

acute gastritis. In conclusion, the results of the present study indicate that ginsenoside Re exerts a preventive effect on the progression of C48/80-induced acute gastric mucosal lesion in rats, possibly by inducing mucus secretion and attenuating enhanced neutrophil infiltration, inflammation, and oxidative stress in gastric mucosa.

“Of the primary energy sources in the human body (carbohydrates, proteins, and lipids), lipids are the most efficient type of energy storage (9 kcal/g) and are hence much more prevalent than carbohydrates or proteins as a form of storage [1]. This makes the process of lipid release a crucial component in understanding human energy metabolism and pathology.
