Curcumin retained cytotoxic activity in oral squamous cell carcinoma under hypoxic, chemoresistant conditions where carboplatin activity declined. Its effects were associated with apoptosis induction and reduced reactive oxygen species, suggesting cytotoxicity that may not depend solely on increased oxidative stress. However, curcumin also increased cancer stem cell-associated marker expression, particularly under hypoxia. This marker enrichment may reflect selective survival, phenotypic adaptation, or stress-induced reprogramming, but functional validation is required. These findings highlight the importance of hypoxia in shaping drug response and treatment-associated cellular adaptation in oral squamous cell carcinoma. |
