| Objective: To explore the differential proteome expressions of lymphocytes in the peripheral blood of the patients with acute
promyelocytic leukemia( APL) sensitive to all- trans retinoic acid( ATRA) and the patients with APL resistant to ATRA. Methods: High
resolution two- dimensional polyacrylamide gel electrophoresis( 2- DE) was used to analyse lymphocytes in the peripheral blood of the patients
with APL sensitive to ATRA and the patients with APL resistant to ATRA. Results: The average protein spots of 2- DE of lymphocytes in the
peripheral blood of the patients with APL sensitive to ATRA and the patients with APL resistant to ATRA were 746? 57 and 617? 41, respectively.
Compared with the patients resistant to ATRA, the expressions of 16 protein spots increased obviously, in the peripheral blood lymphocytes of
the patients with APL sensitive to ATRA, 22, decreased, 4(Mr/ pi: 24. 6kD/ 8. 05, 32. 3kD/ 5. 17, 22. 3kD/ 6. 51, 25. 1kD/ 7. 09) , specifically expressed.
5 protein spots(Mr/ pI: 21. 9kD/ 5. 45, 23. 4kD/ 6. 27, 22. 9kD/ 6. 65, 23. 9kD/ 7. 39, 24. 7kD/ 7. 65) were specifically expressed in the
peripheral blood lymphocytes of the patients with APL resistant to ATRA. Conclusion: From the above- mentioned results, it is concluded that
these proteins may be involved in the mechanism of ATRA resistance, the differential expression analysis of proteomes may be useful to further
study of the ATRA- resistant mechanisms and the molecular markers of APL. |
