Ethnopharmacological Relevance: Mahonia bealei (Fortune) Carrière (M. bealei) is a traditional medicine widely used by the Hmong community in Guizhou. It possesses diverse biological activities and shows promise in cancer treatment; however, contemporary pharmacological research in this area is lacking.
Aims Of The Study: This study aimed to investigate the effects and underlying mechanisms of M. bealei on alcoholic hepatocellular carcinoma (HCC).
Materials And Methods: We initially employed the LC-MS/MS method to identify the compounds present in M. bealei serum. Subsequently, its potential targets were predicted using public databases. Bioinformatics and network pharmacology approaches, such as univariate Cox regression and random forest (RF) algorithms, were utilized to identify differentially expressed genes (DEGs) associated with the prognosis of alcoholic HCC. Survival curve and receiver operating characteristic (ROC) analyses were conducted using alcoholic HCC-related data from TCGA and GEO to determine the diagnostic value of the identified DEGs. Molecular docking using the CDOCKER approach based on CHARMm was performed to validate the affinity between the predictive compounds and targets. Additionally, we evaluated the impact of M. bealei on cell proliferation, migration, and conducted western blot assays.
Results: The LC-MS/MS approach identified 17 therapeutic components and predicted 483 component-related targets, of which 63 overlapped with alcoholic HCC targets and were considered potential therapeutic targets. GO and KEGG pathway analysis revealed significant associations between the 63 overlapping targets and alcoholic HCC progression. Through various approaches in the Cytoscape 3.9.0 software, we confirmed 9 hub genes (CDK1, CXCR4, DNMT1, ESR1, KIT, PDGFRB, SERPINE1, TOP2A, and TYMS) as core targets. TOP2A and CDK1 genes were identified as advantageous for diagnosing alcoholic HCC using univariate Cox regression, RF, survival curve, and ROC analysis. Molecular docking analysis demonstrated strong binding affinity between key bioactive components cyclamic acid, perfluoroalkyl carboxylic acid, perfluorosulfonic acid, alpha-linolenic acid, adenosine receptor antagonist (CGS 15943), and Prodigiosin and TOP2A and CDK1. In vitro experiments confirmed that M. bealei significantly suppressed cell proliferation and migration of HepG2 cells, while downregulating TOP2A and CDK1 expression.
Conclusion: This study highlights the potential of M. bealei as a natural medicine for the treatment of alcoholic HCC. Six compounds (cyclamic acid, perfluoroalkylic carboxylic acids, perfluorosulfonic acid, alpha-linolenic acid, adenosine receptor antagonist (CGS 15943), and Prodigiosin) present in M. bealei serum may exhibit therapeutic effects against alcoholic HCC by downregulating CDK1 and TOP2A expression levels in vitro.

Purpose: The incidence and mortality of hepatocellular carcinoma (HCC) and its underlying etiologies in China are still unclear. Therefore, this study used the Global Burden of Disease (GBD) 2021 to evaluate the incidence and mortality of HCC and its underlying etiologies in China.
Methods: We extracted the incident cases, incidence rate, deaths, and mortality rate of HCC and its underlying etiologies in China in 1990 and 2021 from the GBD database.

Nano-plastics (NPs) are emerging hazardous environmental contaminants that pose health risks with size-dependent toxic effects and are potential risk factors for hepatocellular carcinoma (HCC) and lipid metabolism disorders including non-alcoholic fatty liver disease (NAFLD). However, their underlying molecular mechanisms remain unclear. To shed more light on the causes of these risks, we developed a digestive system microphysiological platform (DS-MPP) for simulating dynamic internal-exposure of multi-size NPs in the gastrointestinal tract and liver.

Background: Non-alcoholic steatohepatitis (NASH) is the most prevalent chronic liver condition globally, with potential progression to cirrhosis, and even hepatocellular carcinoma (HCC). The increasing prevalence of NASH underscores the urgent need for advanced diagnostic and therapeutic strategies. Despite its widespread impact, effective treatments to prevent the progression of NASH remain elusive, highlighting the critical importance of innovative molecular techniques in both the diagnosis and management of this disease.

Introduction: Hepatic resection (HR) and radiofrequency ablation (RFA) are curative treatments for three or fewer hepatocellular carcinomas in Japan. The laparoscopic approach in both has been used in recent years; however, its treatment outcome in combination with HR with RFA is unclear. We aimed to gain insights into this combined treatment.

Background/objectives: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths globally, with prognosis and treatment outcomes that are significantly influenced by the stage at diagnosis. Early detection through regular surveillance is crucial for improving patient outcomes, especially in high-risk groups such as those with cirrhosis or chronic hepatitis B. Geographic variations in HCC risk factors, including viral hepatitis and non-alcoholic fatty liver disease (NAFLD), have led to the development of different international surveillance guidelines.
