Abstract:
Nasopharyngeal carcinoma (NPC) is a malignant tumor with a high prevalence in China. Solasodine is a natural compound derived from the traditional herb that possess anticancer activity in various tumors, but its role in NPC remains unclear. Here, we demonstrated that solasodine potently suppressed NPC growth and induced cell death both in vitro and in vivo. Network pharmacology identified HMOX1 as a pivotal target of solasodine linked to ferroptosis. Solasodine triggered ferroptotic hallmarks, including mitochondrial cristae disruption, elevated Fe2⁺/ROS/MDA, depleted GSH, and dysregulated ferroptosis-related proteins (HMOX1/COX2↑, GPX4/MUC1/SLC40A1↓). Crucially, ferroptosis inhibitors (Fer-1/Lip-1), but not apoptosis, necroptosis, or autophagy inhibitors, rescued solasodine-induced cell death, confirming ferroptosis as the dominant mechanism. In conclusion, by applying network pharmacology accompanied with experimental validation, our study unveils solasodine as a novel ferroptosis inducer for NPC treatment. However, its therapeutic potential requires further validation in patient-derived models and clinical trials.
Insights
Solasodine, a natural compound, effectively inhibits nasopharyngeal carcinoma (NPC) growth by inducing ferroptosis, a specific cell death pathway. This discovery offers a potential new treatment strategy for NPC, requiring further clinical investigation.
Area of Science:
- Oncology
- Pharmacology
- Cell Biology
Background:
- Nasopharyngeal carcinoma (NPC) is a prevalent malignancy in China.
- Solasodine, a natural compound, shows anticancer potential but its mechanism in NPC is unknown.
Purpose of the Study:
- To investigate the efficacy and mechanism of solasodine in treating nasopharyngeal carcinoma.
- To identify the molecular targets and cell death pathways involved in solasodine's action.
Main Methods:
- In vitro and in vivo experiments to assess solasodine's effect on NPC.
- Network pharmacology to identify solasodine's molecular targets.
- Analysis of ferroptosis hallmarks and related proteins.
Main Results:
- Solasodine significantly suppressed NPC growth and induced cell death.
- Network pharmacology identified HMOX1 as a key target, linking solasodine to ferroptosis.
- Solasodine triggered ferroptosis, evidenced by mitochondrial changes, altered iron/ROS/MDA levels, GSH depletion, and specific protein dysregulation. Ferroptosis inhibitors rescued cell death.
Conclusions:
- Solasodine acts as a novel ferroptosis inducer for nasopharyngeal carcinoma treatment.
- The study highlights solasodine's therapeutic potential, warranting further validation in patient-derived models and clinical trials.
