Abstract:
Although the mature neutrophil is one of the better characterized mammalian cell types, the mechanisms of myeloid differentiation are incompletely understood at the molecular level. A mouse promyelocytic cell line (MPRO), derived from murine bone marrow cells and arrested developmentally by a dominant-negative retinoic acid receptor, morphologically differentiates to mature neutrophils in the presence of 10 microM retinoic acid. An extensive catalog was prepared of the gene expression changes that occur during morphologic maturation. To do this, 3'-end differential display, oligonucleotide chip array hybridization, and 2-dimensional protein electrophoresis were used. A large number of genes whose mRNA levels are modulated during differentiation of MPRO cells were identified. The results suggest the involvement of several transcription regulatory factors not previously implicated in this process, but they also emphasize the importance of events other than the production of new transcription factors. Furthermore, gene expression patterns were compared at the level of mRNA and protein, and the correlation between 2 parameters was studied. (Blood. 2001;98:513-524)
Insights
This study details gene expression changes during mouse myeloid differentiation using a retinoic acid-treated cell line. It identifies novel regulatory factors and highlights the importance of post-transcriptional events in neutrophil maturation.
Area of Science:
- Hematology
- Molecular Biology
- Cell Biology
Background:
- Mature neutrophils are well-characterized, but myeloid differentiation mechanisms remain unclear at the molecular level.
- Mouse promyelocytic cell line (MPRO) cells are developmentally arrested and can differentiate into neutrophils with retinoic acid treatment.
Purpose of the Study:
- To catalog gene expression changes during MPRO cell differentiation into mature neutrophils.
- To identify novel molecular players involved in myeloid differentiation.
- To compare gene expression at mRNA and protein levels.
Main Methods:
- 3'-end differential display
- Oligonucleotide chip array hybridization
- 2-dimensional protein electrophoresis
Main Results:
- Identified a large number of genes with modulated mRNA levels during differentiation.
- Suggested involvement of previously unrecognized transcription regulatory factors.
- Highlighted the significance of non-transcription factor-related events.
- Studied the correlation between mRNA and protein expression patterns.
Conclusions:
- Myeloid differentiation involves complex gene expression modulation.
- Novel transcription factors and other regulatory events contribute to neutrophil maturation.
- mRNA and protein expression patterns show variable correlation during differentiation.
