Cos'è il ciclo cellulare?
Cos'è il ciclo cellulare?
The cell cycle refers to the sequence of events occurring throughout a typical cell’s life. In eukaryotic cells, the somatic cell cycle has two ...
Interfase
Interfase
The cell cycle occurs over approximately 24 hours (in a typical human cell) and in two distinct stages: interphase, which includes three phases of the ...
Il sistema di controllo del ciclo cellulare
Il sistema di controllo del ciclo cellulare
The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent ...
Molecole regolatrici positive
Molecole regolatrici positive
Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic ...
Inibizione dell'attività delle CDK
Inibizione dell'attività delle CDK
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be ...
Le S-Cdk iniziano la replicazione del DNA
Le S-Cdk iniziano la replicazione del DNA
The cell cycle is a series of events leading to DNA duplication followed by the division of cell content to form two daughter cells. The cell cycle ...
M-Cdk guida la transizione nella mitosi
M-Cdk guida la transizione nella mitosi
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it ...
Agenti mitogeni e ciclo cellulare
Agenti mitogeni e ciclo cellulare
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell ...
Senescenza cellulare replicativa
Senescenza cellulare replicativa
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while ...
Proliferazione anormale
Proliferazione anormale
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. ...
Le cellule regolano la crescita e la proliferazione
Le cellule regolano la crescita e la proliferazione
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their ...
