Are there new treatments that target cell death to help oral squamous cell carcinoma?
New treatments for oral squamous cell carcinoma (OSCC) are exploring ways to trigger cancer cell death through specific pathways. These include ferroptosis (iron-dependent cell death), cuproptosis (copper-dependent cell death), and autophagy (a process where cells digest themselves). While these approaches are still in early research stages, they offer hope for more targeted therapies.
What the research says
A 2024 study found that phenformin, a drug related to metformin, can trigger autophagy and apoptosis (programmed cell death) in OSCC cells by activating ER stress and increasing levels of proteins like NIBAN1 and DDIT4 9. This effect was independent of AMPK, a common energy sensor, suggesting a new pathway for treatment 9.
Another 2025 study showed that the biological clock gene PER2 can promote cuproptosis in OSCC cells by binding to HSP70 and destabilizing AKT, a protein that helps cancer cells survive 10. When PER2 was increased, it made OSCC cells more sensitive to copper-induced cell death, and combining a PER2 activator with a copper ionophore (elesclomol) enhanced anti-tumor effects in mice 10.
A narrative review highlights ferroptosis and cuproptosis as emerging targets in OSCC, noting their roles in tumor metabolism and immune evasion 4. The review discusses combination strategies that target both pathways to overcome treatment resistance 4.
Additionally, research on iron metabolism and oxidative stress biomarkers found that higher levels of certain markers (like ferritin and reactive oxygen species) are linked to recurrence after surgery, suggesting that targeting these pathways could help prevent relapse 5.
What to ask your doctor
- Are there any clinical trials testing drugs that induce ferroptosis or cuproptosis for OSCC?
- Could phenformin or similar drugs be an option for my treatment plan?
- What is known about the role of the PER2 gene in my type of cancer?
- Should I have my iron and oxidative stress levels checked to assess recurrence risk?
- Are there any dietary or lifestyle changes that might affect these cell death pathways?
