ABSTRACT
Objective To explore the differential expression of CD269 and CD317 in patients with multiple myeloma(MM). Methods Newly diagnosed samles from patients of MM(20 cases)and iron deficiency anemia(20 cases),40 cases in total (from 06/2015 to 08/2013,the Department of Hematology,Central Hospital of Zhuzhou City)were collected.Real-time quantitative PCR(RQ-PCR)tests were used to detect the relative expression of CD269 and CD317 in bone marrow sam-ples,and the results were statistically analyzed with clinical features.Results The relative expression levels of CD269 and CD317 in patients with multiple myeloma(4.418±4.568,4.327±2.876)were significantly higher than those in the control group(0.600±0.838,1.033±1.335),the difference was statistically significant(t=3.676,4.646,all P<0.05)respective-ly,while not related with the gender,age(P>0.05).There was no correlation between the expression of CD269 and CD317 (r=0.041,P=0.864),but positively correlated with the ratio of myeloma cells(r=0.495,P=0.026;r=0.533,P=0.016).Conclusion CD269 and CD317 were highly expressed in patients with multiple myeloma and may be involved in the pathogenesis of multiple myeloma.
