Effects of Chlorine e6 mediated Photodynamic Therapy on MIA PaCa-2 and MRC-5 cells
Abstract
Aim: Pancreatic cancer is an important health problem with high mortality despite current treatment methods. Therefore, new methods for treatment are needed to be developed. Photodynamic therapy (PDT) is based on firstly pre-treatment of tumor region with a light-sensitive (PS) agent, following local accumulation in tumor loci irradiation with appropriate wavelength light source. The aim of this study is to determine the cytotoxic effects of chlorine e-6 based photodynamic therapy on MIA PaCa-2 pancreatic epithelial cancer cells and MRC-5 normal lung (non-cancerous) epithelial cells.
Methods: MIA PaCa-2 pancreatic epithelial cancer cells and MRC-5 normal epithelial cells were incubated with 10 μM Ce6 during 60 min and followed by irradiated with a diode laser (λ =670nm) at 5 J/cm2. Cell proliferation test was performed with WST-1 assay 4 - 24- 48 and 72 hours after post treatment.
Results: Ce6-based photodynamic therapy significantly reduced cell viability in the MIAPaCa-2 group compared to other treatment groups (p <0.05). On the other hand, it was determined that Ce6-based PDT was 33% cytotoxic on MRC-5 cells.
Conclusion: Ce6 concentration, incubation time and laser parameters should be determined separately for each cancer cell line. Ce6 based photodynamic therapy is promising as a palliative treatment option and / or minimizing tumor in pancreatic cancer.
