Cell cycleNormal regulation of the cell cycle ensures the passage of genetic material without mutations and aberrations. Proper completion of each phase is critical to the initiation of the following phase, and the pathways that cell division occur in an ordered, sequential, and irreversible ...
Progress in the eukaryotic cell cycle is driven by oscillations in the activities of CDKs (Cyclin-Dependent Kinases). CDK activity is controlled by periodic synthesis and degradation of positive regulatory subunits, Cyclins, as well as by fluctuations in levels of negative regulators, by CKIs (CDK...

Cell cycle regulationis a major mechanism of stem cell self-renewal and differentiation. FoxOs inhibit cell cycle entry inG1 phaseby upregulating theCdkinhibitors: p27KIP1, p57Kip2, p15INK4b, p19INK4d, the Rb family member p130[92,94,98,99], and by indirectly downregulating D typecyclins...
The cell cycle is the process a cell undertakes to replicate all of its genetic material and divide into two identical cells. In this article, we will look at the different stages of this and what happens in each stage. We will also consider the regulation of the cell cycle, and look at...

Cell-cycle progression inSaccharomyces cerevisiae. Budding yeast serves as an excellent model system to study the cell cycle. Timing and regulation of events are conserved across species. More importantly, the phase of the cell cycle can be deduced by observing the state and size of the bud, th...
It has long been proposed that the cell cycle is regulated by physical forces at the cell–cell and cell–extracellular matrix (ECM) interfaces1–12. However, the evolution of these forces during the cycle has never been measured in a tissue, and whether

cell cycle regulation in different cell types including stem cells [21,35,36]. The role of miRNAs in stem cell proliferation was initially observed in knockout mice lacking Dicer and Dgcr8, which are key components of the miRNA biogenesis [37]. Dicer knockout mice were embryonic lethal and ...
