Proteomic differentiation pattern in the U937 cell line
چکیده انگلیسی

The U937 cell line, originally established from a histiocytic lymphoma, has been widely used as a powerful in vitro model for haematological studies. These cells retain the immature cell phenotype and can be induced to differentiate by several factors, among which 12-O-tetradecanoyl-13-phorbol acetate (TPA). Fully differentiated cells acquire the adherent phenotype and exhibit various properties typical of macrophages. However, in spite of a great deal of research devoted to the U937 cellular model, the molecular basis of biological processes involved in the monocyte/macrophage differentiation remains unclear. The present study has been undertaken to contribute to this knowledge, in order to identify proteomic-based differentiation pattern for the U937 cells exposed to TPA.Present results have highlighted that the U937 cell differentiation is correlated with a significant proteomic modulation, corresponding to about 30% of the identified proteins, including both over- and down-regulated proteins. Negative modulation regarded proteins involved in the regulation of cell proliferation and in metabolic processes. Proteins appearing incremented in macrophagic phenotype include calcium- and phospholipid-binding proteins and several proteins related to the phagocytic activity.Conclusively, we suggest that this new set of differentially expressed proteins may represent meaningful myelo-monocytic differentiation markers to be applied to the study of several haematological diseases.
