This study leveraged the power of network pharmacology, in vitro, and in vivo models to illuminate the effects and mechanisms by which taraxasterol counteracts APAP-induced liver injury.
A protein-protein interaction network was generated from the online databases of drug and disease targets, which were used to screen the targets of taraxasterol and DILI. Core target genes were discovered using the analytical features of Cytoscape, complemented by enrichment analyses of gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). An analysis of oxidation, inflammation, and apoptosis was conducted to evaluate the efficacy of taraxasterol in mitigating APAP-stimulated liver damage in both AML12 cells and mice. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blotting were employed to analyze the potential mechanisms of taraxasterol's role in addressing DILI.
Research identified twenty-four targets where taraxasterol and DILI's actions overlap. The group included nine key targets; they were considered core. GO and KEGG analysis demonstrated that core targets are interconnected with the processes of oxidative stress, apoptosis, and inflammatory responses. In vitro experiments concerning AML12 cells and APAP treatment highlighted taraxasterol's ability to alleviate mitochondrial damage. Live animal studies indicated that taraxasterol lessened the detrimental effects on the liver of mice exposed to APAP, while also suppressing the activity of serum transaminases. In vitro and in vivo studies demonstrated that taraxasterol enhanced antioxidant activity, suppressed peroxide production, and mitigated inflammatory responses and apoptosis. In AML12 cells and mice, taraxasterol exhibited effects by increasing Nrf2 and HO-1 expression, decreasing JNK phosphorylation, reducing the Bax/Bcl-2 ratio, and decreasing caspase-3 expression.
The present study, utilizing network pharmacology alongside in vitro and in vivo investigations, demonstrated taraxasterol's capacity to inhibit APAP-induced oxidative stress, inflammatory responses, and apoptosis in AML12 cells and mice, achieved by impacting the Nrf2/HO-1 pathway, JNK phosphorylation, and the expression of apoptosis-related proteins. This investigation presents novel evidence supporting taraxasterol's efficacy as a hepatoprotective agent.
By combining network pharmacology with in vitro and in vivo experiments, this study showed that taraxasterol suppresses APAP-induced oxidative stress, inflammatory responses, and apoptosis in AML12 cells and mice through modulation of the Nrf2/HO-1 pathway, JNK phosphorylation, and alterations in the expression of apoptosis-related proteins. This research underscores the potential of taraxasterol in the treatment of liver issues, presenting new evidence of its hepatoprotective capabilities.

The global mortality toll from cancer is primarily attributable to lung cancer's significant metastatic capabilities. Although Gefitinib, an EGFR-TKI, exhibits efficacy in metastatic lung cancer, the unfortunate reality is that patient resistance to the treatment is a common occurrence, resulting in a poor prognosis. Ilex rotunda Thunb. is the origin of Pedunculoside (PE), a triterpene saponin that exhibits anti-inflammatory, lipid-lowering, and anti-tumor actions. Nevertheless, the healing effect and potential underlying processes of PE within the context of NSCLC treatment are currently unknown.
Evaluating the inhibitory action and prospective mechanisms of PE on the spread of NSCLC metastases and the development of Gefitinib resistance in NSCLC.
A549/GR cells in vitro were generated by the sustained induction of A549 cells with Gefitinib, applying a low dose followed by a sharp increase with a high dose. The migratory aptitude of the cells was evaluated by means of wound healing and Transwell assays. Furthermore, EMT-associated markers and ROS production were evaluated using RT-qPCR, immunofluorescence, Western blotting, and flow cytometry analyses in A549/GR and TGF-1-treated A549 cells. In mice, B16-F10 cells were injected intravenously, and the effect of PE on tumor metastasis was assessed using hematoxylin-eosin staining, Caliper IVIS Lumina, and DCFH.
To assess DA expression, both immunostaining and western blotting were performed.
By modulating MAPK and Nrf2 pathways, PE countered TGF-1's induction of EMT, achieved by decreasing EMT-related protein expression, reducing ROS levels, and inhibiting the cell's capacity for migration and invasion. In addition, PE treatment led to the recovery of Gefitinib sensitivity in A549/GR cells, mitigating the biological features characteristic of epithelial-mesenchymal transition. Mice treated with PE exhibited a significant decrease in lung metastasis, a phenomenon linked to the restoration of normal EMT protein expression, reduced reactive oxygen species (ROS) production, and the inhibition of MAPK and Nrf2 signaling pathways.
A novel finding from this research demonstrates that PE reverses NSCLC metastasis, resulting in improved Gefitinib responsiveness in Gefitinib-resistant NSCLC, thus suppressing lung metastasis in B16-F10 lung metastatic mice, mediated by the MAPK and Nrf2 pathways. The results of our study point to physical exercise (PE) as a possible inhibitor of cancer spread (metastasis) and a potential enhancer of Gefitinib's effectiveness against non-small cell lung cancer (NSCLC).
This investigation showcases a novel finding: PE reverses NSCLC metastasis, improves Gefitinib sensitivity in resistant cases, and suppresses lung metastasis in the B16-F10 lung metastatic mouse model, all through the MAPK and Nrf2 signaling pathways. Analysis of our data suggests PE could be a potential agent to impede metastasis and improve the efficacy of Gefitinib in cases of non-small cell lung cancer.

The global prevalence of Parkinson's disease, a neurodegenerative disorder, is a notable public health concern. Mitophagy's role in the onset and progression of Parkinson's disease has been established over many years, and its pharmaceutical activation is increasingly recognized as a promising treatment option for individuals affected by Parkinson's disease. Initiating mitophagy necessitates a low mitochondrial membrane potential (m). Our research has demonstrated the ability of morin, a naturally occurring compound, to induce mitophagy, without impacting other metabolic processes. Mulberry fruits, among others, contain the flavonoid Morin.
The study seeks to determine the effect of morin on PD mouse models and to understand the potential molecular pathways at play.
Using flow cytometry and immunofluorescence, the mitophagic response to morin was measured in N2a cells. The mitochondrial membrane potential (m) is detectable by means of the JC-1 fluorescent dye. The examination of TFEB nuclear translocation involved the execution of both immunofluorescence staining and western blot analysis. MPTP (1-methyl-4-phenyl-12,36-tetrahydropyridine), when administered intraperitoneally, resulted in the induction of the PD mice model.
Analysis revealed that morin influenced the nuclear movement of TFEB, the mitophagy regulator, and the activation of the AMPK-ULK1 pathway. Morin's protective effect on dopaminergic neurons was observed in MPTP-induced Parkinson's disease models in vivo, concurrently mitigating behavioral impairments.
Previous observations of morin's potential neuroprotective role in PD, however, fail to fully elucidate the intricate molecular mechanisms. For the first time, we present morin as a novel and safe mitophagy enhancer, underpinning the AMPK-ULK1 pathway and demonstrating anti-Parkinsonian effects, suggesting its potential as a clinical drug for Parkinson's disease treatment.
Although Morin was previously posited to offer neuroprotection in PD, the intricate molecular pathways involved still require clarification. We are reporting, for the first time, morin's function as a novel and safe mitophagy enhancer that impacts the AMPK-ULK1 pathway, showing anti-Parkinsonian effects and implying its potential as a clinical drug for Parkinson's Disease.

Ginseng polysaccharides (GP) show remarkable immune regulatory effects, thus suggesting their potential application in treating immune-related diseases.
