Abstract:
Objective To establish real-time fluorescence quantitative polymerase chain reaction(RFQ-PCR) for measurement of the expression level of a proliferation-inducing ligand(APRIL)and its receptors in children with non-Hodgkin′s lymphoma(NHL).Met-hods Specific primers and TaqMan probes of APRIL and its receptors had been designed,and fluorescence of the PCR products were detected continuously during amplification.According to the standard curves created by plasmid DNA,the expression level of target genes in clinical samples had been determined using software,and these results were presented as the ratios of target genes′ mRNA to ?2 microg-luobulin(?2M)′s mRNA.Results The detection range of RFQ-PCR was between 101-109 ng/L,the coefficient of variation values for both intra-experimental and inter-experimental reproducibility ranged from 1.68% to 5.97% and 6.40% to 10.58%,respectively.The results from 22 samples showed that the expression level of APRIL,B cell maturation antigen(BCMA) and transmembrane activator and calcium modulator and cyclophilin ligand(TACI) in peripheral blood of NHL were significantly higher than those in normal children(P
