To screen and identify potential biomarkers specific for T-cell acute lymphoblastic leukemia (T-ALL).


Sera were collected from 20 newly diagnosed B-cell acute lymphoblastic leukemia (B-ALL) patients and 20 T-ALL patients. Proteins were extracted, purified and digested with trypsin. All specimens were analyzed by isobaric tags for relative and absolute quantification (iTRAQ) and two-dimensional liquid chromatography-tandem mass spectrometry (2DLC-MS/MS) in a data-dependent mode. Enzyme-linked immunosorbent assay (ELISA) was used to analyze the expression of serum soluble L-selectin (sL-selectin).


A total of 468 proteins were identified from distinct peptides. Compared with B-ALL group, 31 proteins were significantly differentially up-regulated while 7 proteins were significantly down-regulated in T-ALL group, sL-selectin was the higher up-regulated in these differential expression proteins. The overexpression of sL-selectin in T-ALL was verified by ELISA.


There are the differentially expressed proteins between T-ALL and B-ALL, and the sL-selectin is specific for T-ALL, which can not only become a new biomarker for the diagnosis and prognosis of T-ALL, but also can be used as a potential target for therapy of this leukemia.
