Abstract

Background: Acute lymphoblastic leukemia (ALL) is a malignancy with aggressive tumors of immature lymphocytes. T-cell immunoglobulin and mucin-domain 3 (TIM-3) is a Type I transmembrane glycoprotein which is involved in cell proliferation. The objective of this research is to determine the TIM-3 expression in peripheral blood (PB) and bone marrow (BM) of 80 samples of normal and ALL patients. Materials and Methods: The amount of mRNA and protein of TIM-3 measured in the BM and PB the mononuclear layer of samples by real-time polymerase chain reaction and Western blotting. Results: Our findings indicated that relative mRNA expression of TIM-3 in PB and BM of the mononuclear layer of ALL patients was 1.7 and 5 times higher than normals, respectively. We also reported that the protein level of TIM-3 in mononuclear cells of ALL patients was 3.2-fold in BM and two-fold in PB more than normals. Conclusion: In conclusion, this study shows that TIM-3 increases in ALL patients, thus the expression of TIM-3 in tumor cells may be considered as a potential predictive factor in ALL patients, which needs to be explored in future. © 2020 Journal of Research in Medical Sciences | Published by Wolters Kluwer - Medknow.
