Kinases involved in cell cycle checkpoint function such as CHK1 and WEE1 also constitute potential therapeutic targets. Their inhibition compromises checkpoint function, causes excessive DNA damage and eventually leads to apoptosis, particularly in cells with compromised p53 function. CDK4/6-selective inh...

All life on earth must cope with constant exposure to DNA-damaging agents such as the Sun's radiation. Highly conserved DNA-repair and cell-cycle checkpoint pathways allow cells to deal with both endogenous and exogenous sources of DNA damage. How much a
Cell cycle checkpoints are regulatory processes that keep an eye on the consistency, dependability, and order of the basic cell cycle events. These includeDNA replicationand repair, chromosomal integrity, maintenance of cell size and functions and appropriatechromosome segregationduring mitosis (Barnum &...
Identify and explain the important checkpoints that a cell passes through during the cell cycle As we just learned, the cell cycle is a fairly complicated process. In order to make sure everything goes right, there are checkpoints in the cycle. Let’s learn about these and how they help ...
Gene ontology (GO) enrichment analysis revealed regulation of cell cycle (cell cycle checkpoint, G1/S transition, DNA strand elongation), and regulation of apoptosis, as the most suppressed GO functional categories in TPX2 and TTK depleted HT-29 cells (Fig. 5a). This data would be ...
Furthermore, the cell cycle checkpoint is also discussed as a key process in the regulation of CDKs. CDKs的激活又依赖于另一类呈细胞周期特异性或时相性表达的细胞周期蛋白(cyclins),而CDKs调节的关键步骤是细胞周期检查点。 3. This research focused on cell cycle checkpoints and apoptosis induced by...
Activation of p38 MAP kinase by DNA double-strand breaks in V(D)J recombination induces a G2/M cell cycle checkpoint Delay of cell cycle progression in response to double-strand DNA breaks (DSBs) is critical to allow time for DNA repair and prevent cellular transformation... G Pedraza-Alva...
