“…Furthermore, BER reduces the excessive production of mitochondrial ROS by activating the PGC-1α signaling pathway, which supports mitochondrial energy balance [74]. Additionally, COR has also been demonstrated to reduce ROS levels [66,75], due to the increased activity of SOD and CAT [76]. Furthermore, the ROS level of the NMN group was dramatically lower compared to both the BER group and COR group, which was due to the better capability of NMN to regulate the mRNA expression levels of antioxidant genes (Figure 3C).…”

Oocyte vitrification is crucial for livestock reproduction, germplasm conservation, and human-assisted reproduction, but the overabundance of lipids is highly detrimental to oocyte development. It is necessary to reduce the lipid droplet content of oocytes before cryopreservation. This study analyzed the impact of β-nicotinamide mononucleotide (NMN), berberine (BER), or cordycepin (COR) on various aspects of bovine oocytes, including lipid droplet content and the expression levels of genes related to lipid synthesis in bovine oocytes, development ability, reactive oxygen species (ROS), apoptosis, and the expression levels of genes associated with endoplasmic reticulum (ER) stress, and mitochondrial function in vitrified bovine oocytes. The results of our study indicated that 1 μM NMN, 2.5 μM BER, and 1 μM COR were effective in reducing the lipid droplet content and suppressing the expression levels of genes involved in lipid synthesis in bovine oocytes. Our findings showed that the vitrified bovine oocytes treated with 1 μM of NMN had a significantly higher survival rate and better development ability compared to the other vitrified groups. Additionally, 1 μM NMN, 2.5 μM BER, and 1 μM COR decreased the levels of ROS and apoptosis, decreased the mRNA expression levels of genes involved in ER stress and mitochondrial fission but increased the mRNA expression levels of genes associated with mitochondrial fusion in the vitrified bovine oocytes. Our study results suggested that 1 μM NMN, 2.5 μM BER, and 1 μM COR effectively decreased the lipid droplet content and enhanced the development ability of vitrified bovine oocytes by lowering ROS levels, reducing ER stress, regulating mitochondrial function, and inhibiting apoptosis. Furthermore, the results showed that 1 μM NMN was more effective than 2.5 μM BER and 1 μM COR.

“…It was reported that 6-gingerol alleviates intracellular ROS in HepG2 cells caused by patulin [ 50 ] and lipopolysaccharide (LPS) [ 51 ]. A previous study reported that PA could cause an increase in intracellular ROS levels [ 52 ]. However, it was not clear about the effect of 6-gingerol on PA-induced intracellular ROS.…”

6-Gingerol, one of the major pharmacologically active ingredients extracted from ginger, has been reported experimentally to exert hepatic protection in non-alcoholic fatty liver disease (NAFLD). However, the molecular mechanism remains largely elusive. RNA sequencing indicated the significant involvement of the AMPK signaling pathway in 6-gingerol-induced alleviation of NAFLD in vivo. Given the significance of the LKB1/AMPK pathway in metabolic homeostasis, this study aims to investigate its role in 6-gingerol-induced mitigation on NAFLD. Our study showed that 6-gingerol ameliorated hepatic steatosis, inflammation and oxidative stress in vivo and in vitro. Further experiment validation suggested that 6-gingerol activated an LKB1/AMPK pathway cascade in vivo and in vitro. Co-immunoprecipitation analysis demonstrated that the 6-gingerol-elicited activation of an LKB1/AMPK pathway cascade was related to the enhanced stability of the LKB1/STRAD/MO25 complex. Furthermore, radicicol, an LKB1 destabilizer, inhibited the activating effect of 6-gingerol on an LKB1/AMPK pathway cascade via destabilizing LKB1/STRAD/MO25 complex stability in vitro, thus reversing the 6-gingerol-elicited ameliorative effect. In addition, molecular docking analysis further predicated the binding pockets of LKB1 necessary for binding with 6-gingerol. In conclusion, our results indicate that 6-gingerol plays an important role in regulating the stability of the LKB1/STRAD/MO25 complex and the activation of LKB1, which might weigh heavily in the 6-gingerol alleviation of NAFLD.

“…The effect of palmitic acid on endothelial cells, smooth muscle cells and macrophages is able to induce the high-fat model in vitro ( 14 , 15 ). Palmitic acid may lead to inflammation and apoptosis of vascular endothelial cells by mediating the PI3K/Akt/endothelial nitric oxide synthase signaling pathway ( 16 ). Palmitic acid induced endothelial lipotoxicity and lectin-like oxidized LDL receptor-1 upregulation by reducing endoplasmic reticulum stress in HUVECs.…”

Late-stage carotid atherosclerosis has a high incidence rate and may lead to various cerebrovascular diseases. The gene expression profile GSE100927 was selected to identify differentially expressed genes (DEGs) in carotid atherosclerosis. Subsequently, protein-protein interaction, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses were conducted. Furthermore, experimental verification was performed using human umbilical vein endothelial cells (HUVECs), human aortic vascular smooth muscle cells (HAVSMCs) and Tohoku Hospital Pediatrics-1 (THP-1)-induced macrophages. The groups were as follows: Control group, solvent control group and palmitic acid group. The levels of reactive oxygen species (ROS) in the three cell types were detected by flow cytometry or fluorescence microscopy. Furthermore, apoptosis of HUVECs and HAVSMCs was assessed by flow cytometry and the nuclear Hoechst 33258 staining of THP-1-induced macrophages was performed. Male late-stage carotid atherosclerosis samples, including 10 control samples and 21 atherosclerosis samples, were selected. Pathway enrichment analysis demonstrated that ‘Toll-like receptor signaling pathway’ was the top pathway associated with the DEGs. MMP7, MMP9, IL1β, C-C motif chemokine ligand 4 (CCL4), secreted phosphoprotein 1 (SPP1), CCL3 and interferon regulatory factor 5 (IRF5) were selected for experimental verification. Palmitic acid increased the ROS levels and the apoptosis rates of HUVECs and HAVSMCs. However, it did not increase the levels of ROS and did not shrink the nuclei of THP-1-induced macrophages. Furthermore, palmitic acid increased the mRNA levels of IL1β, CCL4, SPP1, CCL3, IRF5, MMP7 and MMP9 in HUVECs and THP-1-induced macrophages, and increased the mRNA levels of CCL4 and MMP9 in HAVSMCs. In conclusion, IL1β, CCL3, CCL4, SPP1, IRF5, MMP7 and MMP9 are important markers of late-stage carotid atherosclerosis.
