The Effect of In Vitro Photodynamic Therapy on Increase of Osteopontin and Heat Shock Protein 70 Expression in Squamous Cell and Colon Carcinoma
The aim of the study was investigating whether the 5-ALA-mediated-photodynamic therapy may cause an increase in osteopontin expression in malignant cells, and whether this was accompanied by a parallel increase in an expression of Heat Shock Protein 70.
