Anticancer effects and mechanisms of , and on human lung carcinoma and hepatoma cells.

Herbs are extensively utilized in Traditional Chinese Medicine (TCM) for lung and liver cancer treatment, but the mechanisms behind these herbs remain largely unknown. Here, high-throughput transcriptomic analysis technology was used to uncover molecular mechanisms of herbal treatment. Furthermore, we developed a compound recognition approach utilizing the LINCS L1000 database to identify potential treatment targets. Our results showed that among 14 herbs tested, exhibited the strongest anticancer effects in A549 and Huh7 cells, followed by , and . exerts its anticancer properties by downregulating cell cycle-related transcription factors, including E2F1 and TFDP1. Notably, the mechanisms of treatment differed between the two cell lines. In A549 cells, which possess wild-type p53, induced apoptosis through the regulation of the p53 pathway. In contrast, in Huh7 cells, which harbor mutant p53, the effect was mediated via the TNF-α/NF-κB signaling pathway. We also identified two drugs, AMG232 and Nutlin-3, that exhibited treatment effects similar to in A549 cells. Both drugs function as inhibitors of the MDM2-p53 interaction. Western blot analysis confirmed the alteration of the relevant proteins, aligning with our computational predictions. Furthermore, 23-hydroxybetulinic acid, a key active compound of , demonstrated the ability to inhibit the p53-MDM2 interaction by binding to the same pocket on the MDM2 protein.
