Abstract:
Objective: To testify the location of recombinant adenovirus Ad5/F35-HF2S in chronic myeloid leukemia K562 cells and its interaction with the fusion protein Bcr-Abl. Methods: The recombinant adenovirus Ad5/F35-HF2S was infected into K562 cells, then the expression of fusion protein HF2S in K562 cells was assessed by RT-PCR (reverse transcription-PCR) and Western blotting. The location of HF2S protein in K562 cells was demonstrated by immunofluorescence and Western blotting assay. The immunofluorescence was performed to verify the co-localization of HF2S and Bcr-Abl. The co-immunoprecipitation assay was employed to detect the interaction between HF2S and Bcr-Abl. Results: The leukemia cell line K562 was effectively infected by the adenovirus Ad5/F35-HF2S. The fusion protein HF2S and Bcr-Abl were co-located and interacted with each other in the cytoplasm. Conclusion: HF2S can be successfully expressed and interacted with Bcr-Abl in the cytoplasm of K562 cells. These results provide the basement of the targeted therapy for chronic myeloid leukemia.
