Summary of "Exploring the Underlying Mechanisms of the Coupling between Cell Differentiation and Cell Cycle."

Differentiation and replication are the two major fates of the cells. They are the fundamental processes for completing the cellular functions. Although the underlying biological processes have been considerably explored for each of these processes and significant progresses have been made, global quantification and physical understanding are still challenging especially for the relationship among them. In this study, we developed a theoretical framework for both the cell cycle and cell differentiation by exploring the associated global dynamics and their underlying relationship. We found that the dynamics of the cell cycle and cell differentiation is governed by both the landscape gradient and rotational curl flux. While landscape attracts the system down to the stable state basins, the curl flux drives the stable oscillation flow. We uncovered the irregular Mexican hat landscapes of the cell cycle at different developmental stages. We studied how the cells develop from undifferentiated cells to differentiated cells and how the cell cycle proceeds at different developmental stages. We investigated how the cell differentiation can influence the cell cycle where more progressive differentiation can lead to the changes of the cell cycle oscillations. In contrast, we can also quantitatively illustrate how the cell cycle can influence the cell differentiation where cell cycle regulation can lead to the changes of the differentiation processes. Through the landscape and flux analysis, we uncovered the key regulatory elements controlling the progression of the cell differentiation and cell cycle. This can help to design an effective strategy for drug discovery against associated diseases.

Medical and Biotech [MESH] Definitions

The mechanisms by which a cell becomes internalized in another. The host cell may engulf another as do PHAGOCYTIC CELLS, or the host cell may be invaded by another cell (ENTOSIS), or internalization processes may involve the cooperation of both the host cell and the cell being internalized. Viable cells may remain in non-phagocytic cells (EMPERIPOLESIS), undergo cell division, pass through and then out of the host cell (TRANSCELLULAR CELL MIGRATION), or trigger APOPTOSIS of the invaded cell.

Inhibitor of differentiation proteins are negative regulators of BASIC HELIX-LOOP-HELIX TRANSCRIPTION FACTORS. They inhibit CELL DIFFERENTIATION and induce CELL PROLIFERATION by modulating different CELL CYCLE regulators.

Direct contact of a cell with a neighboring cell. Most such junctions are too small to be resolved by light microscopy, but they can be visualized by conventional or freeze-fracture electron microscopy, both of which show that the interacting CELL MEMBRANE and often the underlying CYTOPLASM and the intervening EXTRACELLULAR SPACE are highly specialized in these regions. (From Alberts et al., Molecular Biology of the Cell, 2d ed, p792)
