ABSTRACT

Based on the gut-liver axis, this study integrated multi-omics and network pharmacology strategies to explore the mechanism of Biejia-Ruangan Compound Tablets(BRC), a preferred Chinese patent medicine for anti-hepatic fibrosis, in alleviating alcoholic liver disease(ALD). The Lieber-DeCarli ethanol liquid diet was used to establish the ALD model, and the pharmacodynamic effects of BRC were evaluated. Non-targeted metabolomics and network pharmacology were employed to screen key metabolites and pathways, while multiple technical methods such as immunohistochemistry were used to verify key molecules in the gut-liver axis. The results showed that BRC significantly improved liver morphology and pathological damage in mice, reduced organ indices, and decreased serum levels of aspartate aminotransferase(AST) and alanine aminotransferase(ALT). BRC also alleviated hepatocellular steatosis, inflammatory infiltration, and fibrosis, and reduced the levels of reactive oxygen species(ROS) and partially restored superoxide dismutase(SOD) activity. Metabolomic analysis indicated that BRC could significantly reverse the disordered metabolic profiles of the intestine and liver, and increase the level of the differential metabolite prostaglandin E_2(PGE_2), which may be closely related to the adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK) signaling pathway. Compared with the model group, BRC effectively upregulated the expression of prostaglandin G/H synthase-2(COX-2) in the small intestine, inhibited the levels of inflammatory factors such as lipopolysaccharide(LPS), tumor necrosis factor-α(TNF-α), and interleukin-1β(IL-1β) in the liver, and promoted the expression of phosphorylated AMP-activated protein kinase catalytic subunit α2(p-AMPKα2), forkhead box protein O1(FOXO1), and peroxisome proliferator-activated receptor gamma coactivator-1α(PGC-1α) in the liver, as well as the activity of cytoplasmic phosphoenolpyruvate carboxykinase 1(PCK1). In conclusion, BRC may alleviate ALD by alleviating hepatic inflammation, oxidative stress, and metabolic disorders through the gut-liver axis via the COX-2/AMPK/FOXO1/PGC-1α/PCK1 signaling pathway. This study provides a scientific basis and new insights for the clinical application of BRC and the prevention and treatment of ALD with TCM.

ABSTRACT

BACKGROUND: Mitochondrial damage can induce the release of mitochondrial DNA (mtDNA), leading to oxidative stress and activation of immune responses. Targeting mitochondrial dysfunction may thus represent a therapeutic strategy for gastric cancer. Isobavachalcone (IBC), a prenylated chalcone derived from Psoralea corylifolia L., has demonstrated antitumor activity, but its mechanism of action remains unclear, limiting its clinical application.

PURPOSE: This study aimed to investigate the antitumor effects of IBC in gastric cancer and to elucidate the underlying molecular mechanisms, with a focus on mitochondrial damage and immune activation.

STUDY DESIGN: The study combined in vitro and in vivo assays with multi-omics sequencing and network pharmacology to identify IBC's therapeutic target and downstream signaling pathways.

METHODS: Gastric cancer cells and mouse models were treated with IBC to assess its inhibitory effects. Multi-omics approaches and network pharmacology were used to identify potential targets. ROS production, mitochondrial membrane integrity, and immune pathway activation were evaluated via biochemical and molecular assays.

RESULTS: IBC significantly suppresses gastric cancer growth both in vitro and in vivo. Integrated analysis identifies dihydroorotate dehydrogenase (DHODH) as a direct target of IBC. DHODH deficiency can induce mitochondrial membrane remodeling and STING pathway activation. Inhibition of DHODH by IBC induces ROS accumulation, mitochondrial membrane remodeling, and activation of the STING pathway, promoting antitumor immune responses. This study demonstrates that IBC enhances antitumor immunity in gastric cancer through mitochondrial damage-mediated mechanisms.

CONCLUSION: IBC exerts dual antitumor and immunostimulatory effects in gastric cancer by targeting DHODH, inducing mitochondrial damage, and activating the STING pathway, highlighting its promising therapeutic potential in gastric cancer.

ABSTRACT

Gastric cancer (GC) remains a major global health burden, with high incidence and mortality rates, particularly in East Asia, driven by factors such as Helicobacter pylori infection, dietary risks, and genetic predispositions. Conventional treatments like surgery and chemotherapy are limited by resistance, toxicity, and poor outcomes in advanced stages. The PI3K/Akt/mTOR and MAPK signaling pathways are central to GC pathogenesis, promoting proliferation, survival, metabolic reprogramming, epithelial-mesenchymal transition (EMT), and metastasis through aberrations like PIK3CA mutations, PTEN loss, and KRAS alterations. These pathways exhibit extensive crosstalk, contributing to therapeutic resistance. This review explores the regulatory effects of Traditional Chinese Medicine (TCM) on these pathways in GC, grounded in TCM principles such as Qi deficiency, Damp-Heat, and disharmony of the Spleen and Stomach. Single herbal monomers (e.g., curcumin, berberine, resveratrol) inhibit PI3K/Akt/mTOR by upregulating PTEN and suppressing mTOR, inducing autophagy and apoptosis. Classical herbs like Huangqin and Huanglian modulate Akt and ERK phosphorylation, while compound formulas (e.g., Banxia Xiexin Decoction, Sijunzi Decoction) synergistically target both pathways, reversing EMT and chemoresistance. TCM addresses crosstalk by disrupting feedback loops and reducing inflammation, enhancing efficacy in combination with Western therapies like chemotherapy and immunotherapy. Network pharmacology and multi-omics analyses reveal TCM's multitarget mechanisms, aligning with ZHENG-based personalization. Challenges include research variability, standardization issues, and incomplete mechanistic validation. Future directions emphasize high-quality trials, omics integration, and precision TCM for clinical translation. TCM offers low-toxicity, holistic options for integrative GC management, potentially improving survival and quality of life.
