| Outline of Final Research Achievements |
We performed cellular experiments to explore molecular basis for squamous cell carcinoma stem cell based photodynamic therapy (PDT) using talaporphin sodium. The cells with igher levels of CD44 variant are to be targeted via cistine transporter-glutathione in which cells are to be resistant to oxidative stress. For this aim, we performed MTS and glutathione-generation assay in the setting of PDT under sulphasarazopirine (SASP) administration. The results showed SASP had nominal additional effects on PDT.
