There were no significantly different respective transcript levels of PTTG1IP in the CML NRs (mean ΔCtPTTG1IP = 2.87 ± 2.57; FCPTTG1IP = 3.05) or R (mean ΔCtPTTG1IP = 2.38 ± 1.69, FCPTTG1IP = 2.67) group than in the control group (mean ΔCtPTTG1IP = 3.07 ± 0.93). This evidence concerns the gene PTTG1IP and chronic myelogenous leukemia, BCR-ABL1 positive.
