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 ...
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

E3 ubiquitin ligases play essential roles in the degradation and regulation of CKIs during cell cycle progression. During the G2/M phase, the targeting of CKIs for degradation is primarily mediated by the APC/C E3 ubiquitin ligase complex. At other phases of the cell cycle, CRL complexes als...
These findings suggest that the regulation of EPOR mRNA level is mainly associated with GATA-1 gene expression in UT-7 cells undergoing proliferation, and that these serial events are under the control of, or related to, the cell cycle.
Cell cycle regulation is clinically very relevant, as uncontrolled proliferation is a hallmark of cancer. To study the cell cycle in mammalian cells, there have been several comprehensive proteomic studies on protein abundance (Herr et al., 2020; Lane et al., 2013; Ly et al., 2017, 2014; ...
coliandB. subtilis, tightly regulate cell cycle progression to achieve consistent cell size distributions and replication dynamics. Many of the hallmark features of these model bacteria, including lateral cell wall elongation and symmetric growth and division, do not occur in mycobacteria. Instead, ...

Cells in G0 phase are not actively preparing to divide. The cell is in a quiescent (inactive) stage that occurs when cells exit the cell cycle. Some cells enter G0 temporarily until an external signal triggers the onset of G1. Other cells that never or rarely divide, such as mature ...
