The use of anti-CD71 as the affinity ligand for AML detection in this work yields a capture efficiency and purity during peak CD71 expression of 92% and 62%, respectively.
We discovered that AML with high expression level of CD71 was prone to linked with severe anemia (P=0.004), thrombocytopenia (P<0.001) and complex karyotype (P=0.024) and had increasing expression level of CD117 (P=0.001).
In the seven cases of acute erythroid leukemia (AEL), leukemic cells rarely expressed CD71, with the mean CD71 expression level significantly lower than that of acute megakaryocytic leukemia (p < 0.05), and also lower than that of poorly differentiated AML and normal blasts but without statistical significance.
We examined expression levels of TfR1, TfR2-alpha (membrane form) and TfR2-beta (non-membrane form) transcripts in cells from 67 patients with de novo acute myeloid leukaemia (AML) using reverse transcription-polymerase chain reaction (RT-PCR), and correlated the results with a variety of clinical features and disease outcomes of these patients.
We examined transferrin receptor (TfR) 1 and TfR2 mRNA expression in 50 acute myeloid leukemia (AML) patients by RT-PCR, with primers specific for exons 15-17 (TfR1), 3-5 (TfR2-alpha) and 4-5 (TfR2-beta) of the corresponding gene.
In the present study, we evaluated TfR gene expression at the molecular level in bone marrow (BM) samples of 44 patients with de novo acute myeloid leukaemia (AML) at diagnosis with BM blasts > 85%.
