Cell Cycle Regulation

This lecture covers the regulation of the cell cycle, focusing on the decision-making process during the G1 phase, the impact of growth factors on cell cycle progression, and the role of cyclin-dependent protein kinases (CDKs) in controlling cell cycle progression. It also discusses the activation of transcription factors by growth factors, the combinatorial control of gene expression by factors like Jun and Myc, and the regulation of CDKs by CDK inhibitors. The lecture emphasizes the complexity of cell cycle regulation in mammalian cells, highlighting the multiple levels of control and feedback loops involved.
