Impact of Intermittent Fasting and Dietary Restriction on Redox State, Energetic Metabolism, and Liver Injury in Common Bile Duct Ligation Model. Antioxidants (Basel) 2024; 13:835. [PMID: 39061903 PMCID: PMC11273810 DOI: 10.3390/antiox13070835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2024] [Revised: 07/03/2024] [Accepted: 07/09/2024] [Indexed: 07/28/2024] Open
Abstract
The aim of this work was to test whether we can treat cholestasis with dietary approaches applied after the onset of the disease. The effects of intermittent fasting and dietary restriction on liver damage caused by common bile duct ligation (BDL) in rats were studied, with particular attention paid to changes in the activity of enzymes of energy metabolism and antioxidant protection. Morphological changes in liver tissue and serum markers of liver damage were assessed in rats with BDL kept for one month on ad libitum diet, intermittent fasting, or 35% dietary restriction. We studied parameters of glucose metabolism (activity of glycolysis and gluconeogenesis enzymes), TCA cycle, and indicators of oxidative stress and redox status of the liver tissue. Dietary restriction resulted in an increase in gluconeogenesis activity, antioxidant capacity, and autophagy activation. When implemented after BDL, none of the dietary restriction protocols reduced the level of oxidative stress, detrimental morphological and biochemical alterations, or the fibrosis progression. Thus, under severe damage and oxidative stress developing in cholestasis, dietary restrictions are not hepatoprotective and can only be used in a pre-treatment mode.

Liu M, Mo H, Gao Q, Yuan L. The pH dependence of emulsifying properties for glutathione disulfide at oil-water interfaces. Biophys Chem 2021; 282:106748. [PMID: 34959125 DOI: 10.1016/j.bpc.2021.106748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Revised: 12/03/2021] [Accepted: 12/20/2021] [Indexed: 11/30/2022]
Abstract
Although peptides were widely used in many fields, their interface behaviors as surfactants have not been explored. The results of the surface tension experiments by an automatic surface tension meter indicate that the stability and emulsifying ability of glutathione disulfide (GSSG) under alkaline conditions were stronger than those under acidic conditions. With encoding the different oxygen and nitrogen atoms in GSSG, as well as the different hydrogen atoms bonded with oxygen and nitrogen atoms. The pH Dependence of the number of hydrogen bonds, affected by the protonation and deprotonation of the functional groups in GSSG, is calculated by LAMMPS software. The results demonstrate that GSSG forms twice as many hydrogen bonds under alkaline conditions as under acidic conditions, resulting in a better surface-interface activity in alkaline conditions. The interface properties of the GSSG surfactant can be regulated by pH. Therefore, GSSG is a potential pH-responsive surfactant.
