Previous cytotoxic (anticancer) evaluations ofElephantopus molliswere mainly focused on its elephantopin derivatives neglecting the combined effect of the phytochemicals in its traditionally used extracts. In this study, the cytotoxic mechanism of its extracts was investigated using methylene blue assay. The cytotoxic screening results revealed the ethyl acetate extract as the most potent extract by displaying prominent dose-dependent and time-dependent growth inhibitions in human liver carcinoma HepG2 cells with the lowest EC50value of 9.38 ± 0.43 µg/mL after 72 hours of treatment. Acute exposure of the HepG2 cells to the ethyl acetate extract produced a significant regulation of caspase-3 with the peak expression at 8 hours of treatment (P< .05). DNA fragmentation indicated by DeadEnd Apoptosis Detection System-labeled nuclei cells confirmed that the extract induced apoptotic cell death through caspase-3-dependent pathway in HepG2 cells.

Hyperlipidemia is a major risk factor for hypertension, coronary heart disease, diabetes and stroke, triggering an intensified research efforts into its prevention and treatment. Tetrahydroberberrubine (THBru) is a derivative of berberine (BBR) that has been shown to have higher bioavailability and lower toxicity compared to its parent compound. However, its impact on hyperlipidemia has not been fully explored.

Background: Naringenin, a flavonoid compound found in citrus fruits, possesses valuable anticancer properties. However, its potential application in cancer treatment is limited by poor bioavailability and pharmacokinetics at tumor sites. To address this, Naringenin nanoparticles (NARNPs) were prepared using the emulsion diffusion technique and their anticancer effects were investigated in HepG2 cells.

Hepatocellular carcinoma (HCC) necessitates innovative prognostic biomarkers and therapeutic targets. By investigating PNMA1 in HCC via the TCGA and GEO databases and our clinical data, we found that its overexpression is associated with worse survival. The relevance of PNMA1 extends to immune factors such as M1 macrophages, CD8 T cells, and immune checkpoints.

In this study, we delve into the intrinsic mechanisms of cell communication in hepatocellular carcinoma (HCC). Initially, employing single-cell sequencing, we analyze multiple malignant cell subpopulations and cancer-associated fibroblast (CAF) subpopulations, revealing their interplay through receptor-ligand interactions, with a particular focus on SPP1. Subsequently, employing unsupervised clustering analysis, we delineate two clusters, C1 and C2, and compare their infiltration characteristics using various tools and metrics, uncovering heightened cytotoxicity and overall invasion abundance in C1.

Background: Pyroptosis is closely associated with chemotherapeutic drugs and immune response. Here, we investigated whether oxaliplatin, a key drug in FOLFOX-hepatic artery infusion chemotherapy (FOLFOX-HAIC), induces pyroptosis in hepatoma cells and enhances antitumor immunity after tumor cell death.
Methods: Hepatoma cells were treated with oxaliplatin.
