BACKGROUND This study was conducted to investigate the effect of dietary rutin on the meat quality, antioxidant status and mitochondrial structure and function in the breast muscle of heat-stressed broilers. A total of 192 male broilers were randomly assigned into three groups and treated with normal control (CON), heat stress (34 °C, HS), and HS with 500 mg kg −1 rutin supplementation (HS + Rutin), respectively. RESULTS Dietary rutin significantly reversed HS-induced decrease in body weight, average daily feed intake, average daily gain, and feed efficiency. Rutin supplementation attenuated HS-induced impaired meat quality by decreasing the lightness, drip loss at 24 and 48 h, the peak time of free water ( T 22 ) and the peak area ratio of free water ( P 22 ), and increasing the pH 24h and peak area ratio of immobilized water ( P 21 ). Rutin supplementation promoted superoxide dismutase, glutathione peroxidase activities and total antioxidant capacity, and decreased malondialdehyde levels compared with the HS group. Moreover, rutin attenuated HS-induced mitochondrial damage by increasing the mitochondrial DNA copy number and improving mitochondrial morphology. Dietary rutin significantly increased mitochondrial biogenesis-related mRNA (proliferator-activated γ receptor coactivator-1α [PGC-1α], nuclear respiratory factor 1 [NRF1], and mitochondrial transcription factor A [TFAM]) expression via the AMP-activated protein kinase (AMPK) signaling pathway. HS significantly increased mitophagy-related genes and proteins (Parkin, PTEN-induced putative kinase 1 [PINK1], microtubule associated protein light chain 3-II [LC3-II]) expression, and dietary rutin significantly reversed these alterations. CONCLUSION Dietary rutin attenuated the HS-induced decline in meat quality and antioxidant capacity of broilers, which may be related to inhibition of the AMPK/PINK1–Parkin signaling pathway to attenuate mitochondrial damage. © 2023 Society of Chemical Industry.

Nonalcoholic fatty liver disease (NAFLD), especially nonalcoholic steatohepatitis (NASH), is a common hepatic manifestation of metabolic syndrome. However, there are no effective therapy to treat this devastating disease. Accumulating evidence suggests that the generation of elastin-derived peptides (EDPs) and the inhibition of adiponectin receptors (AdipoR)1/2 plays essential roles in hepatic lipid metabolism and liver fibrosis. We recently reported that the AdipoR1/2 dual agonist JT003 significantly degraded the extracellular matrix (ECM) and ameliorated liver fibrosis. However, the degradation of the ECM lead to the generation of EDPs, which could further alter liver homeostasis negatively. Thus, in this study, we successfully combined AdipoR1/2 agonist JT003 with V14, which acted as an inhibitor of EDPs–EBP interaction to overcome the defect of ECM degradation. We found that combination of JT003 and V14 possessed excellent synergistic benefits on ameliorating NASH and liver fibrosis than either alone since they compensate the shortage of each other. These effects are induced by the enhancement of the mitochondrial antioxidant capacity, mitophagy, and mitochondrial biogenesis via AMPK pathway. Furthermore, specific suppression of AMPK could block the effects of the combination of JT003 and V14 on reduced oxidative stress, increased mitophagy and mitochondrial biogenesis. These positive results suggested that this administration of combination of AdipoR1/2 dual agonist and inhibitor of EDPs–EBP interaction can be recommended alternatively for an effective and promising therapeutic strategy for the treatment of NAFLD and NASH related fibrosis.

Excessive molybdenum (Mo) and cadmium (Cd) are toxic environmental pollutants . Our previous research confirmed excessive Mo and Cd co-induced calcium homeostasis disorder and autophagy in duck kidneys, but how calcium ion (Ca 2+ ) regulates autophagy is unclear. The results revealed that the Mo- and/or Cd-induced cytosolic Ca 2+ concentration ([Ca 2+ ] c ) increase mainly came from intracellular calcium stores. Mo and/or Cd caused mitochondrial Ca 2+ content ([Ca 2+ ] mit ) and [Ca 2+ ] c increase with endoplasmic reticulum (ER) Ca 2+ content ([Ca 2+ ] ER ) decrease and upregulated calcium homeostasis-related factor expression levels, but 2-Aminoethoxydiphenyl borate (2-APB) reversed subcellular Ca 2+ redistribution. Increased Phospholipase C (PLC) and inositol 1,4,5-trisphosphate (IP 3 ) activities and inositol 1,4,5-trisphosphate receptor (IP 3 R) expression level were observed in Mo- and/or Cd-treated cells, which was reversed by the PLC inhibitor U-73122. 2-APB and 1,2-Bis (2-aminophenoxy) ethane-N,N,N′,N′-tetraacetic acid acetoxymethyl ester (BAPTA-AM) addition mitigated [Ca 2+ ] c and autophagy (variations in microtubule-associated protein light chain 3 (LC3), LC3B-II/LC3B-I, autophagy related 5 (ATG5), sequestosome-1(P62), programmed cell death-1 (Beclin-1) and Dynein expression levels, LC3 puncta, autophagosomes and acid vesicle organelles) under Mo and/or Cd treatment, respectively, while thapsigargin (TG) had the opposite impacts. Additionally, the calmodulin-dependent protein kinase kinase β (CaMKKβ) inhibitor STO-609 reversed the increased CaMKKβ, adenosine 5′-monophosphate-activated protein kinase (AMPK), Beclin-1, and LC3B-II/LC3B-I protein expression levels and reduced mammalian target of rapamycin (mTOR) and P62 protein expression levels in Mo- and/or Cd-exposed cells. Collectively, the results confirmed that [Ca 2+ ] c overload resulted from PLC/IP 3 /IP 3 R pathway-mediated ER Ca 2+ release, and then activated autophagy by the CaMKKβ/AMPK/mTOR pathway in Mo- and/or Cd-treated duck renal tubular epithelial cells.

Oocytes and embryos are highly sensitive to environmental stress in vivo and in vitro. During in vitro culture, many stressful conditions can affect embryo quality and viability, leading to adverse clinical outcomes such as abortion and congenital abnormalities. In this study, we found that valeric acid (VA) increased the mitochondrial membrane potential and ATP content, decreased the level of reactive oxygen species that the mitochondria generate, and thus improved mitochondrial function during early embryonic development in pigs. VA decreased expression of the autophagy-related factors LC3B and BECLIN1 . Interestingly, VA inhibited expression of autophagy-associated phosphorylation-adenosine monophosphate-activated protein kinase (p-AMPK), phosphorylation-UNC-51-like autophagy-activated kinase 1 (p-ULK1, Ser555), and ATG13, which reduced apoptosis. Short-chain fatty acids (SCFAs) can signal through G-protein-coupled receptors on the cell membrane or enter the cell directly through transporters. We further show that the monocarboxylate transporter 1 (MCT1) was necessary for the effects of VA on embryo quality, which provides a new molecular perspective of the pathway by which SCFAs affect embryos. Importantly, VA significantly inhibited the AMPK-ULK1 autophagic signaling pathway through MCT1, decreased apoptosis, increased expression of embryonic pluripotency genes, and improved embryo quality.

AMPKα1 and AMPKα2, key kinases in regulating energy homeostasis, have not been previously cloned or characterized in common carp ( Cyprinus carpio ). This study identified the open reading frame (ORF) sequences of ampkα1 (1722 bp, encoding 573 amino acids) and ampkα2 (1659 bp, encoding 552 amino acids) through homologous cloning. Sequence alignment and phylogenetic analysis showed a high similarity of both genes with fish homologs. Expression analysis revealed that ampkα1 and ampkα2 are widely expressed across tissues in carp, with ampkα1 highly expressed in the gonads and ampkα2 in the heart. Fasting significantly reduced ampkα1 expression in the heart, adipose tissue, and foregut but increased it in the hindgut and white muscle. Similarly, ampkα2 expression decreased in the hypothalamus and muscle during fasting, with an increase in the midgut. Glucose tolerance tests showed dynamic regulation of ampkα1 and ampkα2 , with initial downregulation followed by upregulation in the hepatopancreas, red muscle, and brain. High-glucose and high-fat diets significantly increased ampkα1 and ampkα2 expression in multiple tissues. Insulin and glucagon treatment induced time-dependent changes in both genes in hepatocytes, while Aeromonas hydrophila infection, LPS, and Poly (I:C) stimulation upregulated ampkα1 and ampkα2 in immune-related tissues. Knockdown of ampkα2 , but not ampkα1 , reduced glut1b mRNA levels, while both knockdowns of ampkα1 and ampkα2 promoted the expression of gsk3β , pygm , acc , fas , srebp , cs , and pro-inflammatory cytokines, suggesting their involvement in metabolic and immune regulation in carp.

Metabolic dysfunction‑associated steatotic liver disease (MASLD) is an increasingly significant global health burden for which there is currently no effective treatment. The present study aimed to explore the underlying mechanisms and investigate the effects of donafenib and atorvastatin in MASLD. The effects of donafenib and atorvastatin on the activity and lipid metabolism of HepG2 cells were analyzed in vitro. A rat model of MASLD was established induced by a high‑fat diet in vivo. H&E and Oil red O staining were used to observe the improvement in MASLD, western blotting analysis was used to detect the expression of proteins related to fat metabolism and immunofluorescence was used to detect reactive oxygen species (ROS) levels. In vitro, donafenib and atorvastatin inhibited lipid accumulation in HepG2 cells. In vivo, donafenib and atorvastatin activated the AMP‑activated protein kinase (AMPK) pathway, downregulated the expressions of proteins related to fatty acid synthesis (sterol regulatory element‑binding protein‑1, 3‑hydroxy‑3‑methylglutaryl‑CoA reductase and fatty acid synthase) and upregulated the expression of proteins related to fatty acid β‑oxidation (carnitine palmitoyl‑transferase 1C and acyl‑CoA oxidase). The levels of free fatty acids, cholesterol and triglycerides in the liver and serum decreased in all three treatment groups. Additionally, donafenib and atorvastatin reduced oxidative stress in the liver tissue and decreased ROS levels. Low‑dose donafenib combined with atorvastatin improved MASLD by regulating fatty acid metabolism and reducing oxidative stress through activation of the AMPK signaling pathway.

Scope Allicin, a product of enzymatic reaction when garlic is injured, plays an important role in maintaining glucose homeostasis in mammals. However, the effect of allicin on glucose homeostasis in the state of insulin resistance remains to be elucidated. This study investigates the effect of allicin on glucose metabolism using different muscle fibers in a chicken model. Methods and results Day-old male Arbor Acres broilers are randomly divided into three groups and fed a basal diet supplemented with 0, 150, or 300 mg kg −1 allicin for 42 days. Results show that allicin improves the zootechnical performance of broilers at the finishing stage. The glucose loading test (2 g kg −1 body mass) indicates the regulatory role of allicin on glucose homeostasis. In vitro results demonstrate allicin increases glutathione (GSH) level and the expression of cystathionine γ lyase (CSE), leading to endogenous hydrogen sulfide (H 2 S) production in M. pectoralis major (PM) muscle-derived myotubes. Allicin stimulates adenosine monophosphate-activated protein kinase (AMPK) S-sulfhydration and AMPK phosphorylation to promote glucose uptake, which is suppressed in the presence of d , l -propargylglycine (PAG, a CSE inhibitor). Conclusion This study demonstrates that allicin induces AMPK S-sulfhydration and AMPK phosphorylation to promote glucose uptake via the CSE/H 2 S system in a muscle fiber-dependent manner.

Bisphenol A (BPA) is a typical endocrine disrupting chemical widely distributed in the environment and in food systems. The adverse effects of BPA on reproductive health have posed major concerns worldwide. The aim of this study was to determine the potential of epigallocatechin gallate (EGCG) to protect against BPA-induced male reproductive toxicity and investigate the underlying protective mechanism. The protective effects of EGCG on BPA-induced reproductive toxicity were investigated using male zebrafish model. The results showed that EGCG alleviated BPA-induced developmental toxicity of F1 generation of zebrafish, reversed testis disorder and combated the blood-testis barrier (BTB) damage caused by BPA in zebrafish. In order to unravel the underlying mechanism, TM4 cell - constructed BTB model was used for further study. The results indicated that EGCG counteracted the damage induced by BPA on the integrity of BTB model and reduced the autophagy caused by BPA. Furthermore, EGCG effectively inhibited the BPA-induced upregulation of the expression level of AMPK (p-AMPKα/AMPKα), significantly restored the BPA-mediated downregulation of the expression levels o。f p-mTOR/mTOR, p-AKT/AKT and Raptor. The results suggested that EGCG mitigated the BPA-induced male reproductive toxicity through maintaining the integrity of BTB by inhibiting the autophagy mediated by AMPK/AKT/mTOR signaling pathway. This study provided a strategy for combating the BPA-induced reproductive toxicity using a well-known bioactive component as a potential therapeutic approach.

Ethnopharmacological relevance PolyphyllinVI (PPⅥ) is the main bioactive component of Chonglou which is a traditional Chinese herbal with various effects, including antitumor, anti-inflammatory, and analgesia. Aim of the study This study aimed to investigate the properties and mechanisms of the analgesia of PPⅥ by using neuropathic pain (NPP) mice. Materials and methods The potential targets and mechanisms of PPⅥ in alleviating NPP were excavated based on the network pharmacology. Subsequently, the construction of a spared nerve injury (SNI) mice model was used to evaluate the effect of PPⅥ on NPP and the expression of the P2X3 receptor. We identified the signaling pathways of PPⅥ analgesia by RNA sequencing. Results The results of network pharmacology showed that BCL2, CASP3, JUN, STAT3, and TNF were the key targets of the analgesic effect of PPⅥ. PPⅥ increased the MWT and TWL of SNI mice and decreased the level of P2X3 receptors in the dorsal root ganglion (DRG) and spinal cord (SC). Additionally, PPⅥ reduced the release of pro-inflammatory mediators (TNF-α, IL-1β, and IL-6) in the DRG, SC, and serum. Based on the KEGG enrichment of differentially expressed genes (DEGs) identified by RNA-Seq, PPVI may relieve NPP by regulating the AMPK/NF-κB signaling pathway. Western blotting results showed that the AMPK signaling pathway was activated, followed by inhibition of the NF-κB signaling pathway. Conclusion PPⅥ increased the MWT and TWL of SNI mice maybe by inhibiting the expression of the P2X3 receptor and the release of inflammatory mediators. The properties of the analgesia of PPⅥ may be based on the AMPK/NF-κB pathway.

Osteoarthritis (OA) is a prevalent chronic degenerative joint disease worldwide. Obesity has been linked to OA, and increased free fatty acid levels (e.g., palmitate) contribute to inflammatory responses and cartilage degradation. Xanthohumol (Xn), a bioactive prenylated chalcone, was shown to exhibit antioxidative, anti-inflammatory, and anti-obesity capacities in multiple diseases. However, a clear description of the preventive effects of Xn on obesity-associated OA is unavailable. This study aimed to assess the chondroprotective function of Xn on obesity-related OA. The in vitro levels of inflammatory and ECM matrix markers in human chondrocytes were assessed after the chondrocytes were treated with PA and Xn. Additionally, in vivo cartilage degeneration was assessed following oral administration of HFD and Xn. This study found that Xn treatment completely reduces the inflammation and extracellular matrix degradation caused by PA. The proposed mechanism involves AMPK signaling pathway activation by Xn, which increases mitochondrial biogenesis, attenuates mitochondrial dysfunction, and inhibits NLRP3 inflammasome and the NF-κB signaling pathway induced by PA. In summary, this study highlights that Xn could decrease inflammation reactions and the degradation of the cartilage matrix induced by PA by inhibiting the NLRP3 inflammasome and attenuating mitochondria dysfunction in human chondrocytes.

Impaired infected wound healing is closely associated with mitochondrial dysfunction, and ferroptosis has emerged as a key mechanism connecting oxidative stress to mitochondrial damage. Baicalein holds potential for modulating this process, yet its application is constrained by poor bioavailability. Herein, a multifunctional nano-delivery system (Ba@Zn-MSN@CH) was rationally designed for infected wound treatment. Zinc-doped mesoporous silica nanoparticles (Zn-MSN) were synthesized to serve as a baicalein carrier. Carboxymethyl chitosan (CMCS) and dihydrocaffeic acid were covalently grafted onto the surface of the nanoparticles via silanization and amidation reactions, leading to the formation of a stable core-shell structure. The introduction of macromolecular coating was found to not only prolong drug release but also enhance antioxidant and antibacterial efficacy. What's more, Ba@Zn-MSN@CH effectively alleviated mitochondrial damage by inhibiting ferroptosis, thereby restoring cell proliferation, migration, and angiogenesis, and ultimately accelerating infected wound healing. Mechanistically, Ba@Zn-MSN@CH inhibited ferroptosis by inducing AMP-activated Protein Kinase α (AMPKα) phosphorylation in fibroblasts. AMPKα sustained the abundance of nuclear factor erythroid 2-related factor 2 (Nrf2), which subsequently suppressed lipid peroxidation and inhibited ferroptotic cell death through upregulation of downstream antioxidant factors. Collectively, these findings demonstrated that Ba@Zn-MSN@CH accelerated infected wound healing by inhibiting ferroptosis through activation of the AMPK/Nrf2 signaling pathway, highlighting the potential of baicalein-based nanotherapeutics as a promising strategy for infected wound management.

Fucoidan is a sulfated polysaccharide derived from brown algae ( Saccharina japonica ), and exhibits immunomodulatory properties. Emerging evidence suggests a strong correlation between the development of food allergy and intestinal dysfunction. The present study aimed to investigate the potential anti-food allergy activity of fucoidan and to elucidate its mechanism at the intestinal barrier function. The ovalbumin (OVA)-induced allergy mouse model was established, exhibiting increased OVA-specific IgE, histamine, Th2 inflammatory response, and intestinal damage. Oral administration of fucoidan markedly alleviated allergic symptoms by inhibiting mast cell activation and modulating intestinal immune responses. Furthermore, fucoidan significantly ameliorated intestinal immunological dysregulation, maintained barrier integrity, modulated gut microbiota composition, and enhanced short-chain fatty acid (SCFA) production. Mechanistically, the protective effects of fucoidan were closely associated with activation of the AMPK/SIRT1/FOXO1 pathway, which correlated with improved intestinal barrier function. Collectively, these results demonstrate that fucoidan may protect against food allergy by enhancing intestinal barrier function, highlighting the potential of natural biological substances in addressing food allergy.
