[PMID: 36009249 PMCID: PMC9405457 DOI: 10.3390/antiox11081530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 08/01/2022] [Accepted: 08/03/2022] [Indexed: 12/02/2022] Open
Abstract
The development of single enantiomers with high efficiency and low toxic activity has become a hot spot for the development and application of drugs and active additives. The aim of the present study was to investigate the effectiveness of the application of α-lipoic acid with a different optical rotation to alleviate the inflammation response and oxidative stress induced by oxidized fish oil in laying hens. Sixty-four 124-week-old Peking Red laying hens were randomly allocated to four groups with eight replicates of two birds each. The normal group was fed basal diets supplemented with 1% fresh fish oil (FO), and the oxidative stress model group was constructed with diets supplemented with 1% oxidized fish oil (OFO). The two treatment groups were the S-form of the α-lipoic acid model with 1% oxidized fish oil (OFO + S-LA) and the R-form of the α-lipoic acid model with 1% oxidized fish oil (OFO + R-LA) added at 100 mg/kg, respectively. Herein, these results were evaluated by the breeding performance, immunoglobulin, immune response, estrogen secretion, antioxidant factors of the serum and oviduct, and pathological observation of the uterus part of the oviduct. From the results, diets supplemented with oxidized fish oil can be relatively successful in constructing a model of inflammation and oxidative stress. The OFO group significantly increased the levels of the serum inflammatory factor (TNF-α, IL-1β, IL-6, and IFN-γ) and the oxidative factor MDA and decreased the activity of the antioxidant enzyme (T-AOC, T-SOD, GSH-Px, GSH, and CAT) in the oviduct. The addition of both S-LA and R-LA significantly reduced the levels of serum inflammatory factors (TNF-α, IL-1β, IL-6, and IFN-γ), increased the activity of antioxidant indexes (T-AOC, T-SOD, GSH-Px, GSH, and CAT), and decreased the MDA contents in the serum and oviduct. Meanwhile, the supplementation of S-LA and R-LA also mitigated the negative effects of the OFO on the immunoglobulins (IgA and IgM) and serum hormone levels (P and E2). In addition, it was worth noting that the R-LA was significantly more effective than the S-LA in some inflammatory (IL-1β) and antioxidant indices (T-SOD, GSH, and CAT). Above all, both S-LA and R-LA can alleviate the inflammation and oxidative damage caused by oxidative stress in aged laying hens, and R-LA is more effective than S-LA. Thus, these findings will provide basic data for the potential development of α-lipoic acid as a chiral dietary additive for laying hens.

Abstract
α-lipoic acid (ALA) is a naturally occurring antioxidant with protective effects against various hepatic injuries. The aim of the present study was to investigate the mechanisms by which ALA protects the liver from carbon tetrachloride (CCl4)-induced liver cirrhosis. The widely used liver cirrhosis rat model was established via an intraperitoneal injection of 2 mg/kg 50% CCl4, three times/week for 8 weeks. Simultaneously, 50 or 100 mg/kg ALA was orally administrated to the rats every day for 8 weeks. The activity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was detected in the serum. The pathological liver injuries were analyzed using hematoxylin and eosin and Masson's trichrome staining. The principal factors involved in the transforming growth factor-β (TGF-β)/mothers against decapentaplegic homolog 9 (Smad3) and protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathways and in autophagy were examined using reverse transcription-quantitative polymerase chain reaction or western blot analysis. The results demonstrated that the administration of ALA alleviated CCl4-induced liver injury, as demonstrated by decreased ALT and AST activity, improved pathological injuries and reduced collagen deposition. The CCl4-induced increase in TGF-β and phosphorylated-Smad3 expression levels was additionally inhibited by treatment with ALA. Furthermore, the administration of ALA reversed the CCl4-induced upregulation of light chain 3II and Beclin-1, and downregulation of p62. The CCl4-induced suppression of the AKT/mTOR pathway was additionally restored following treatment with ALA. In combination, the results of the present study demonstrated that ALA was able to protect CCl4-induced liver cirrhosis, an effect that may be associated with inactivation of the TGF-β/Smad3 pathway and suppression of autophagy.

Abstract
Introduction The aim of the study was to assess the influence of α-lipoic acid (ALA) on the morphology of the aorta and liver of rabbits fed high fat diet with addition of oxidised (ORO) and non-oxidised rapeseed oil (N-ORO). Material and Methods The study was conducted on male chinchilla rabbits divided into six groups. The control group (C) was fed a breeding standard diet (BSD), group I received BSD with the addition of ALA in the dose of 10 mg/kg b.w., groups II and III received BSD enriched with 10% addition of N-ORO or ORO, whereas rabbits from groups IV and V received BSD with 10% addition of N-ORO or ORO and ALA. Results Addition of ORO caused necrosis and steatosis of hepatocytes, as well as atherosclerotic plaques of various intensification in the aorta. In the liver of rabbits from group II (N-ORO) infiltrations of mononuclear cells was observed in the area of liver triads and between liver lobules. The beneficial influence of ALA was demonstrated in rabbits fed a diet containing N-ORO or ORO. In case of ORO, the activity of ALA was not fully effective. Conclusion Diet supplementation with ALA counteracts the changes generated in the liver and aorta under increased exposure to higher fat content in diet, in particular thermally treated fats.

Abstract
To explore the protective efficacy of α-lipoic acid (ALA) against Cd-prompted neurotoxicity, young male New Zealand rabbits (Oryctolagus cuniculus) were divided randomly into four groups. Group 1 (control) received demineralized water. Group 2 (Cd) administered cadmium chloride (CdCl2) 3 mg/kg bwt. Group 3 (ALA) administered ALA 100 mg/kg bwt. Group 4 (Cd + ALA) administered ALA 1 h after Cd. The treatments were administered orally for 30 consecutive days. Cd-induced marked disturbances in neurochemical parameters were indicated by the reduction in micro- and macro-elements (Zn, Fe, Cu, P, and Ca), with the highest reduction in Cd-exposed rabbits, followed by Cd + ALA group and then ALA group. In the brain tissues, Cd has significantly augmented the lipid hydroperoxides (LPO) and reduced the glutathione (GSH) and total antioxidant capacity (TAC), and glutathione peroxidase and glutathione S-transferase enzyme activities but had an insignificant effect on the antioxidant redox enzymes. Administration of ALA effectively restored LPO and sustained GSH and TAC contents. Moreover, Cd downregulated the transcriptional levels of Nrf2, MT3, and SOD1 genes, and upregulated that of Keap1 gene. ALA treatment, shortly following Cd exposure, downregulated Keap1, and upregulated Nrf2 and GPx1, while maintained MT3 and SOD1 mRNA gene expression in the rabbits' brain. These data indicated the ALA effectiveness in protecting against Cd-induced oxidative stress and the depletion of cellular antioxidants in the brain of rabbits perhaps due to its antioxidant, free radical scavenging, and chelating properties.

Abstract
Nicotine mediates some of the injurious effects caused by consuming tobacco products. This work aimed at investigating the defensive role of alpha-lipoic acid (ALA) with its known antioxidant and antiinflammatory effect in nicotine-induced lung and liver damage. Rats were arranged into 4 groups: control, nicotine, ALA, and ALA–nicotine groups. Oxidative stress and antioxidant status were determined by assessing thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD), and glutathione (GSH) levels in lung and liver. Liver enzymes and lipid profiles were measured and pulmonary and hepatic damage were assessed by histopathological examination. Also, serum levels of transforming growth factor beta 1 (TGF-β1) and vascular cell adhesion molecule 1 (VCAM-1) were determined. The results revealed an increase in TBARS in tissues and a reduction in both SOD and GSH activity in the nicotine-treated rats. Nicotine induced high levels of liver enzymes, TGF-β1, VCAM-1, and dyslipidemia with histopathological changes in the lung and liver. ALA administration along with nicotine attenuated oxidative stress and normalized the SOD and GSH levels, ameliorated dyslipidemia, and improved TGF-β1 and VCAM-1 with better histopathology of the lung and liver. The study data revealed that ALA may be beneficial in alleviating nicotine-induced oxidative stress, dyslipidemia, and both lung and liver damage.
