Abstract Objective: To investigate the effects of 5-aminolevulinic acid (ALA) and/or imatinib mesylate on the content of porphyrin and the expression of ABCG2 protein in HSC-2 of keratinocytes and basal cell carcinoma of HaCaT, and to provide theoretical basis for further improving the clinical efficacy of PDT. Methods: HaCaT keratinocytes and HSC-2 basal cell carcinoma cell lines were cultured with or without imatinib mesylate. The content of ABCG2 protein was determined by Western blotting, the content of porphyrin in cells was detected by ELISA, and the location of porphyrin in cells was observed by confocal laser scanning microscope. Results: In HaCaT cells and HSC-2 cells, the combination of ALA and imatinib mesylate could improve the accumulation of Protoporphyrins in HSC-2 cells, and enhance the cell death induced by PDT. At the same time, compared with the combination of ALA and imatinib mesylate, the combination of ALA and imatinib mesylate could significantly reduce the expression of ABCG2 protein To enhance the killing effect of PDT on HSC-2 cells. Conclusion: This study reveals the possible reasons for the decreased sensitivity of ALA-PDT in the treatment of BCC, and provides a theoretical basis for the further improvement of the efficacy of ALA-PDT combined with imatinib mesylate in the treatment of BCC.
