Acute alcoholic liver disease (ALD) resulting from short-term heavy alcohol consumption has become a global health concern. Moreover, anthocyanins have attracted much attention for their ability to prevent oxidation and inflammation. The present work evaluates the protective effects of Lycium ruthenicum Murray (LRM) against ALD and explores the possible underlying mechanism involved. The total anthocyanin content in LRM was 43.64 ± 9.28 Pt g/100 g dry weight. Mice were orally administered 50, 125, or 375 mg LRM/kg body weight (BW) for 21 days. On days 18–21, mice were orally administered 15 mL of ethanol/kg BW. Markers of liver damage, oxidative stress, and inflammation were examined. Furthermore, the modulatory effect of LRM on Nrf2/HO-1/NF-κB pathway molecules was evaluated through quantitative reverse transcription polymerase chain reaction (RT‒qPCR) and immunohistochemistry analyses. The difference between the groups indicated that LRM improved liver histopathology and the liver index, decreased aspartate transaminase, alanine transaminase, malondialdehyde, reactive oxygen species, IL-6, TNF-α, and IL-1β expression, but elevated superoxide dismutase, catalase, and glutathione-s-transferase levels. Moreover, LRM upregulated Nrf2 and Ho-1 but downregulated Nf-κb and Tnf-α genes at the transcript level. In summary, LRM alleviated ethanol-induced ALD in mice by reducing oxidative damage and associated inflammatory responses. LRM protects against ALD by reducing damage factors and enhancing defense factors, especially via the Nrf2/HO-1/NF-κB pathway. Thus, LRM has application potential in ALD prophylaxis and treatment.

This study investigated the protective effect of Dai Bai Jie (DBJ) extract against acute alcoholic liver injury (AALI) and elucidated its potential mechanism. The total saponin level in the DBJ extracts was measured using vanillin–chloroform acid colorimetry. To observe the preventive and protective effects of DBJ on AML-12 cells in an ethanol environment, the effective components of DBJ were identified. An alcohol-induced AALI mouse model was used to evaluate the efficacy of DBJ against AALI. For this purpose, alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) levels were assessed, liver function indices and oxidative and inflammatory markers were determined, and histopathological examinations were performed. Mechanistic investigations were conducted using RT-qPCR assays and immunohistochemical analysis to determine the protective effects of DBJ. The samples (DBJ-1, DBJ-2, and DBJ-3) were obtained by extracting DBJ with water, 50% ethanol, and 95% ethanol, yielding total saponin contents of 5.35%, 6.64%, and 11.83%, respectively. DBJ-3 was isolated and purified, and its components were identified by Ultra Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS). DBJ-3 had the greatest effect on cell viability in an ethanol environment. Moreover, DBJ-3 reduced inflammatory infiltration, liver cell degeneration, and hemorrhage, while increasing ADH and ALDH levels in liver tissues. Additionally, DBJ-3 considerably decreased the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (TC), and triglyceride (TG) levels. DBJ-3 reduced malondialdehyde (MDA), reactive oxygen species (ROS), and inflammatory factors, such as tumor necrosis factor (TNF-α), interleukin-1β (IL-1β), and interleukin 6 (IL-6), while increasing superoxide dismutase (SOD) and glutathione S-transferase (GST) activities. Furthermore, DBJ-3 significantly increased alcohol dehydrogenase 1b (ADH1B) and aldehyde dehydrogenase 2 (ALDH2) expression at the gene and protein levels within alcohol metabolism pathways and reduced the nuclear factor kappa-B (NF-κB) gene and protein levels. These findings suggest that DBJ-3 can prevent AALI by enhancing alcohol metabolism via the regulation of ADH1B and ALDH2 and the modulation of the NF-κB pathway to improve antioxidant and anti-inflammatory effects.

Breast cancer remains a leading cause of malignancy-related mortality among women, with rising global incidence. While surgical intervention is effective for early-stage breast cancer, drug therapy is indispensable, particularly for triple-negative breast cancer, where treatment options are still limited. Actaea vaginata, a traditional Chinese medicinal herb, has been historically applied for inflammatory conditions, including pharyngitis and stomatitis. However, its antitumor potential remains under-reported. In this study, a cycloartane triterpene saponin, beesioside O (BO), was isolated from this plant. Its antitumor activity was evaluated in vitro. Its potential therapeutic mechanisms were elucidated through network pharmacology. BO exhibited substantial potency in inhibiting breast cancer cells. Network pharmacology analysis uncovered 179 potential pharmacological targets of BO, which were predominantly concentrated in pathways, such as pathways in cancer, the PI3K-Akt signaling pathway, and chemical carcinogenesis receptor activation. Molecular docking analysis indicated that STAT3 exhibited minimal binding energy with BO. Additionally, molecular dynamics simulations verified the conformational stability of the BO-STAT3 complex. Western blot analysis demonstrated that STAT3 was downregulated following administration. These results imply that BO may exhibit a multi-target, synergistic therapeutic effect against breast cancer, with STAT3 recognized as a pivotal target. This study demonstrates the potential of BO for development as a chemotherapeutic agent for breast cancer treatment. It lays the groundwork for further exploration of BO’s bioactivity and provides valuable insights into its molecular mechanisms in breast cancer therapy.

Objectives: Bisphenol A (BPA), a prototypical environmental endocrine-disrupting chemical (EDC), is ubiquitously present in environmental matrices and biological fluids. Dietary ingestion and inhalation exposure to BPA can induce testicular oxidative stress and apoptosis. This study aimed to investigate the protective effects and underlying mechanisms of Pfaffia glomerata (Pg), a perennial herb of the Amaranthaceae family, against BPA-induced reproductive system injury. Methods: Potential targets and molecular mechanisms were predicted through network pharmacology. Physiological indicators, histopathological changes, serum biochemical parameters, and Western blot analysis were used to systematically evaluate the ameliorative effects of Pg and elucidate its mechanisms. Results: Our network pharmacology analysis identified core targets of Pg in attenuating reproductive system injury, including PTPN11, PIK3CA, JAK2, PIK3R1, PDGFRB, and others. GO enrichment and KEGG pathway analysis indicated that these key targets primarily regulate steroid metabolism, enhance antioxidant capacity, and modulate signaling pathways such as PI3K-AKT, Fc epsilon RI, and cAMP. In vivo studies demonstrated that all Pg dose groups showed significant improvement in BPA-induced histopathological injury to testicular tissues. BPA exposure increased serum levels of follicle-stimulating hormone (FSH) while decreasing testosterone (T), estradiol (E2), and progesterone (PROG) levels. Furthermore, BPA elevated serum levels of the testicular marker enzymes acid phosphatase (ACP) and lactate dehydrogenase (LDH) but reduced alkaline phosphatase (ALP) levels; all these effects were significantly reversed with Pg treatment. Western blot results showed that compared with the model group, high-dose Pg significantly upregulated the expression of phosphorylated AKT (p-AKT), phosphorylated PI3K (p-PI3K), and Bcl-2, while downregulating Cleaved Caspase-3 and Bax. Conclusions: Our findings indicate that Pg may attenuate BPA-induced reproductive system injury by activating the PI3K/AKT signaling pathway, upregulating the anti-apoptotic protein Bcl-2, and inhibiting the activation of the apoptotic effector Caspase-3. The study provides a new theoretical basis for the development of novel natural drugs or health products.
