Summary. Placental-like alkaline phosphatase (PLAP) is expressed by many tumors and can be detected in sera of patients with various cancers. Its aberrant expression has been considered to be potentially useful as tumor marker. However, the biological background of the role of this aberrant alkaline phosphatase (AP) in cancer is still unclear. The expression of various forms of AP in cells of chronic myeloid leukemia (CML) has not yet been studied. Aim: To analyze the expression patterns of various AP forms in cells originated from CML patients in blast crisis and to modify their expression by vitamin E. Materials and Methods: RNA extracted from leukemic cells was converted to cDNA and real-time reverse transcription polymerase chain reaction was performed using SYBR Green protocol with primers to tissue non-specific alkaline phosphatase (TNAP), intestinal alkaline phosphatase and CCAAT-enhancer-binding proteins alpha (C/EBPα). To analyze the modulation of expression of APs and C/EBPα, CML cells were incubated with 100 µM vitamin E. Results: We have observed the aberrant expression of mRNA intestinal alkaline phosphatase in CML cells that upon sequencing demonstrated the significant alignment with PLAP sequence while no gene homology with tissue placental alkaline phosphatase (PAP) was revealed. Vitamin E decreases mRNA PLAP expression and increases mRNA TNAP expression. Moreover, along with down-regulation of aberrant PLAP and up-regulation of TNAP, vitamin E increases C/EBPα mRNA expression. Conclusion: The loss of TNAP in CML may contribute to pathogenesis of this disease. PLAP may be considered as a putative target in differentiation therapies in myeloid neoplasms. Our findings suggest the potential role of vitamin E as the inducer of differentiation potential of leukemic cells in CML. |
