    • The present invention relates to a method of testing whether a patient suffering of multiple myeloma will respond or not to a DNA methyltransferase inhibitor (DNMTi) comprising: i. determining the expression level (ELi) of several genes G1-Gn selected from table A in a biological sample obtained from said patient ii. comparing the expression level (ELi) determined at step i) with a predetermined reference level (ELRi) iii. calculating the DMS score trough the following formula (I) wherein &bgr;1 represent the regression &bgr; coefficient reference value for the gene Gi and Ci=1 if the expression of the gene Gi (ELi) is higher than the predetermined reference level (ELRi) or Ci=−1 if the expression of the gene (ELi) is lower than or equal to the predetermined reference level (ELRi) comparing the score DMS determined at step iii) with a predetermined reference value DMSR and concluding that the patient will respond to the DNMTi when the DMS score is higher than the predetermined reference value DMSR or concluding that the patient will not respond to the DNMTi when the DMS score is lower than the predetermined reference value DMSR. DMS = ∑ i = 1 n  &bgr;  i × Ci ( I )
    • 本发明涉及一种测试患有多发性骨髓瘤的患者是否会对DNA甲基转移酶抑制剂(DNMTi)起反应的方法,包括:i。 测定从所述患者ii获得的生物样品中选自表A的几个基因G I-G n的表达水平(ELi)。 将步骤i)确定的表达水平(ELi)与预定参考水平(ELRi)iii进行比较。 通过以下公式(I)计算DMS得分,其中如果基因G i(ELi)的表达高于预定参考水平(ELRi),则其表示基因G i和Ci = 1的回归β系数参考值, 或如果基因(ELi)的表达低于或等于预定参考水平(ELRi),则Ci = -1,将步骤iii)确定的评分DMS与预定参考值DMSR进行比较,并推断患者将响应 当DMS分数高于预定参考值DMS R时,向DNMTi发送该分数,或者当DMS分数低于预定参考值DMS R时,推断患者不会响应DNMTi。
