RESUMEN
With the profound study of PDT mechanism and the new type of photosensitizers,the application of PDT to hematopoietic diseases has become a new domain.The relapsing/refractory aggressive lymphoma is one of the tough problems which are still unsolved in hematopoietic domain. Now,the experimental and clinical research on application of PDT in lymphomas has become the hot topic for the domestic and world scholars.
RESUMEN
Objective: To investigate the expression of Cyclin G mRNA in leukemia patients and its clinical significance. Methods: RT-PCR was used to analyze the expression of Cyclin G mRNA in the mononuclear cells of 129 leukemia patients and 10 healthy controls. Results: (1) The expression of Cyclin G in acute leukemia (AL) and chronic leukemia (CL) patients was significantly higher than that in healthy controls (both P 50?109/L in AL and AML groups were significantly higher than those with WBC ≤ 50?109/L. (4) Fifty-three of the newly diagnosed cases were Cyclin G positive. The remission rate of patients with high Cyclin G expression(51.7%)was significantly lower than that with low Cyclin G expression(79.1%)(P
RESUMEN
Objective:To investigate the effect of SU11248 proliferation and apoptosis of multiple myeloma cell line U266 in vitro and analyze its mechanisms.Methods:Effect of SU11248 on proliferation of U266 cells was detected by MTT assay.The ability of SU11248 to induce apoptosis of U266 cells was examined by cell cycle analysis,TUNEL and DNA fragmentation.Expression of c-myc,hTERT,Bcl-2 and Bax mRNA in U266 cells was assessed by RT-PCR analysis.Results:The proliferation of U266 cells was inhibited by SU11248 in dose-and time-dependent manners (P
RESUMEN
Objective:To explore the expression and clinical significance of IRF-1 gene in leukemia.Methods:Revert polymerase chain reaction(RT-PCR) and gel image analysis system were used to analyse the expression of IRF-1 gene in 77 leukemias and 4 leukemic cell lines.Results:IRF-1 gene was found in 18 patients with acute leukemia.Significant low expression of IRF-1 gene was detected in the acute leukemia?chronic myelogenous leukemia(CML) and 3 leukemic cell lines HL 60 K 562 and U 937 compared with the normal and non-mallignant hematonosis (P
