Phosphorylation-dependent changes orchestrate almost every step of cell division, from entry into mitosis to cytokinesis. These changes are mediated by several different protein kinases, including the Aurora and Cyclin-dependent kinases. Here is the latest research examining the role of protein kinases in mitosis.
Cell cycle checkpoints are a series of complex checkpoint mechanisms that detect DNA abnormalities and ensure that DNA replication and repair are complete before cell division. They are primarily regulated by cyclins, cyclin-dependent kinases, and the anaphase-promoting complex/cyclosome. Here is the latest research.
Key regulators of cell cycle, including cyclins, cyclin dependent kinase inhibitors, DNA replication factors, are controlled by proteolysis. Discover the latest research on cell cycle control and proteolysis.
Computational modeling and the theory of nonlinear dynamical systems allow one to not simply describe the events of the cell cycle, but also to understand why these events occur. Discover the latest research on cell cycle modeling here.
Cell cycle is a complex process regulated by several signal transduction pathways and enzymes. Here is the latest research on regulation of cell cycle and cell cycle pathways.
Centromere identity must be maintained through multiple generations. A new study reveals a Constitutive Centromere-Associated Network (CCAN)-dependent retention of CENP-A, a key epigenetic mark for centromeres, in centromeres during DNA replication and a replication-dependent error correction to eliminate ectopic CENP-A in chromosome arms. Discover the latest research on centromere in DNA replication here.
The centromere is a specialized DNA sequence of a chromosome that links a pair of sister chromatids. During prophase, specialized regions of the centromeres known as kinetochores attach chromosomes to spindle fibers. Here is the latest research on centromeres and the kinetochore.
Collective cell migration is the coordinated movement of cells, which organize tissues during morphogenesis, repair and some cancers. Here is the latest research.
Cyclins and cylin-dependent kinases (CDKs) are two classes of regulatory molecules that determine a cell’s progression through cell cycle. Here is the latest research.
Embryogenesis is the process by which the embryo forms and develops. It starts with the fertilization of the egg cell (ovum) by a sperm cell, (spermatozoon). Once fertilized, the ovum is referred to as a zygote, a single diploid cell. The zygote undergoes mitotic divisions with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of a multicellular embryo
During organogenesis, the endoderm of vertebrates produces tissue within the lungs, thyroid, and pancreas
