Cellular responses of p53

A complete range of tools to advance your research on p53 and its cellular responses. 

The tumor suppressor gene, p53, responds to a range of cellular stresses by functioning as both a transcription factor and inhibitor. Here we discuss the main cellular responses and suggest products for the protein targets involved.

Cell cycle arrest and p53

p53 can inhibit cell cycle progression in multiple ways: by the upregulation of p21, which in turn inhibits members of the cyclin dependent kinase family, or by the transcriptional regulation of Gadd45 and 14-3-3σ expression.

To explore the different p53 responsive proteins that facilitate cell cycle arrest please see our products below.



Angiogenesis and p53

p53 plays a key role in preventing the process of angiogenesis taking place by stimulating the production of a number of genes and inhibiting others. This includes stimulating Tsp1 and BAI1, anti-angiogenic factors; and inhibiting VEGF, a pro-angiogenic factor.

Apoptosis and p53

p53 stimulates a wide network of signals that act through the extrinsic and intrinsic apoptosis pathways. The extrinsic pathway involves activation of ‘death’ receptors, which leads to the activation of apoptosis- inducing caspases.  The intrinsic apoptotic pathway is dominated by the Bcl-2 family of proteins, which also trigger cell death via the common execution caspase cascade.

Senescence and p53

As an alternative to apoptosis, p53 can induce senescence in response to high levels of stress, thought to be mediated by p53 targets p21 and plasminogen activator inhibitor 1 (PAI-1).
