Abstract
- Objective: Breast cancer is one of the most widespread tumors among women worldwide, which is difficult to treat due to the presence of chemoresistance and the risk of tumor recurrence and metastasis. There is a pressing necessity to develop efficient treatments to improve response for treatment and increase prolong survival of breast cancer patients. Photodynamic therapy (PDT) has attracted interest for its features as a noninvasive and relatively selective cancer treatment. This method relies on light-activated photosensitizers that, upon absorbing light, generate reactive oxygen species (ROS) with powerful cell-killing outcomes. Nuclear factor kappa B (NF-κB), a transcription factor, plays a key role in cancer development by regulating cell proliferation, differentiation, and survival. Inhibiting NF-κB can sensitize tumor cells to chemotherapeutic agents. Dimethyl fumarate (DMF), an NF-κB inhibitor approved by the FDA for multiple sclerosis treatment, has further shown promise in suppressing breast cancer cell growth in vitro. We hypothesized that combining PDT with Dimethyl fumarate (DMF) could further enhance therapeutic efficacy for both treatment modalities.<br />Methods: In the current study, we explored the PDT effect of 1 and 2 mM aminolaevulinic acid (ALA) and low-power He-Ne laser irradiation combined with different concentrations of DMF (2.5, 1.25, or 0.652 µg/ml) against hormone nonresponsive AMJ13 breast cancer cell line that is derived from Iraqi patient.<br />Results: Our results demonstrated that co-administration with all tested DMF concentrations significantly enhanced the cytotoxicity of PDT antitumor effect. The combination index analysis showed presence of synergism in combining PDT with DMF.<br />Conclusion: This finding suggests that the combination of PDT with DMF could be a promising novel strategy against triple negative breast cancer that could be applied clinically due to the fact that both of these treatments are already clinically approved therapies.
