摘要
目的 定量分析初诊慢性B淋巴细胞白血病(B-CLL)患者外周血单个核细胞和血浆中增殖诱导配体(APRIL)mRNA及蛋白的表达水平并分析其临床意义.方法 采用实时荧光定量聚合酶链反应(RFQ-PCR)及酶联免疫吸附试验(ELISA)方法,检测32例B-CLL患者及15名健康对照靶基因及靶蛋白含量.结果 RFQ-PCR检测APRIL mRNA含量,批内和批间重复性测定的变异系数(CV)分别为1.69%~6.98%和6.49%~10.27%.B-CLL患者APRIL mRNA及蛋白表达水平均显著高于健康对照(均P<0.05),各期组间比较差异均有统计学意义(均P<0.05),有治疗指征组mRNA及蛋白表达水平均高于无治疗指征组(P<0.05).结论 APRIL可能参与B-CLL的发生、发展并与其分期密切相关,且可能成为预测疾病进展的有效因子及治疗靶点.
Objective To quantitatively analyze the mRNA and protein expression level of a proliferation-inducing ligand (APRIL) and investigate its clinical significance in peripheral blood mononuclear cells and plasma from newly diagnosed patients with B-cell chronic lymphocytic leukemia (B-CLL).Methods The mRNA of the target gene in 32 B-CLL patients and 15 health controls was quantified with real-time fluorescence quantitative polymerase chain reaction (RFQ-PCR) and protein by enzyme-linked immunosorbent assay (ELISA).Results APRIL mRNA was assayed with RFQ-PCR,the intra-and inter-batch reproducibility showed the coefficient of variation (CV) were 1.69 %-6.98 % and 6.49 %-10.27 %,respectively.The expressions of APRIL mRNA and protein in patients with B-CLL were significantly higher than those in control (P 〈 0.05),and significant difference was noted among the comparable stages in the arms (P 〈 0.05).The expression of APRIL mRNA and protein in TDI (treatment-demand-indicator) arm was significantly higher than those in non-TDI arm (P 〈 0.05).Conclusions APRIL may be involved in the formation and development of B-CLL and be an influence factor for disease staging.Thus,APRIL may be a prognostic indicator as well as the therapy target for the disease.
