Objective:To investigate the photodynamic effects in vitro of new photosensitizer B-CPD5 to breast cancer cell MCF-7, observe the associated effect with selective cyclooxygenase-2 inhibitor NS398 and explore the related mechanism in order to provide basal confirm for clinical application of photodynamic therapy on breast cancer chest wall recurrence.
Methods:MCF-7 cells were cultured and divided groups, added with different concentration of new photosensitizer B-CPD5, then lighted with 650nm wave length...
