Interconnection between Metabolism and Cell Cycle in Cancer Trends in Biology Diagrams

Interconnection between Metabolism and Cell Cycle in Cancer Trends in Biology Diagrams The relationship between metabolism and cell cycle progression is complex and bidirectional. Cells must rewire metabolism to meet changing biosynthetic demands across cell cycle phases. In turn, metabolism can influence cell cycle progression through direct regulation of cell cycle proteins, through nutrient-sensing signaling pathways, and

Regulation of cell proliferation by metabolism evolved in part to cope with nutritional deprivation, explaining why mechanisms arose to reduce cell growth and arrest cell cycle progression in conditions of starvation. 5 A key regulatory step early in the G 1 phase of the cell cycle is the growth factor-dependent restriction point, when cells During cell-cycle progression, metabolism is regulated to sustain schematically protein synthesis in G1 phase, nucleotide synthesis in S phase, and lipid synthesis in G2 phase. In G1 phase, until the cell growth step in mid-to-late G1, several glycolytic enzymes are inhibited by cycD-CDK6 and APC Cdh1 complexes, the latter also reducing TCA

The bidirectional relationship between metabolism and cell cycle ... Biology Diagrams

In conclusion, while incompletely understood, cell cycle progression is tightly coupled to intracellular metabolism. Emerging evidence suggests that intracellular kinases such as AMPK and mTOR can sense energy intermediates such as AMP, ADP and amino acids and subsequently direct how biosynthetic intermediates are used and whether the cell

Cell cycle progression and division is regulated by checkpoint controls and sequential activation of cyclin-dependent kinases (CDKs). Understanding of how these events occur in synchrony with metabolic changes could have important therapeutic implications. For biosynthesis, cancer cells enhance glucose and glutamine consumption. Inactivation of pyruvate kinase M2 (PKM2) promotes transcription We discuss how metabolism changes during different phases of the cell cycle to sustain biosynthesis and replication in normal and cancer cells. We also highlight how several master regulators of cell cycle, such as cyclin-cyclin-dependent kinases (cyc-CDK complexes) and E3 proteasome ligases, modulate key metabolic enzymes to support cell-cycle

Linking metabolism and cell cycle progression via the APC/C Biology Diagrams

Proliferating cells must double each component of their mass over the course of the cell cycle to produce two daughter cells. Biosynthetic demands differ in each cell cycle phase [1,2]; therefore, metabolism must change in response to cell cycle progression. Cell cycle control must also be responsive to metabolic state to ensure that division only proceeds if cells can produce sufficient
