  2. p53 - Wikipedia

    en.wikipedia.org/wiki/P53

    p53, also known as Tumor protein P53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory protein that is often mutated in human cancers. The p53 proteins (originally thought to be, and often spoken of as, a single protein) are crucial in vertebrates , where they prevent cancer formation. [ 5 ]

  3. Apoptosome - Wikipedia

    en.wikipedia.org/wiki/Apoptosome

    P53 causes cells to enter apoptosis and disrupt further cell division therefore preventing that cell from becoming cancerous (16). In the majority of cancers it is the p53 pathway that has become mutated resulting in lack of ability to terminate dysfunctional cells.

  4. p53 upregulated modulator of apoptosis - Wikipedia

    en.wikipedia.org/wiki/P53_upregulated_modulator...

    The p53 upregulated modulator of apoptosis (PUMA) also known as Bcl-2-binding component 3 (BBC3), is a pro-apoptotic protein, member of the Bcl-2 protein family. [5] [6] In humans, the Bcl-2-binding component 3 protein is encoded by the BBC3 gene. [5] [6] The expression of PUMA is regulated by the tumor suppressor p53.

  5. Suicide gene - Wikipedia

    en.wikipedia.org/wiki/Suicide_gene

    In the field of genetics, a suicide gene is a gene that will cause a cell to kill itself through the process of apoptosis (programmed cell death). Activation of a suicide gene can cause death through a variety of pathways, but one important cellular "switch" to induce apoptosis is the p53 protein.

  6. Apoptosis - Wikipedia

    en.wikipedia.org/wiki/Apoptosis

    The addition of agents such as Herceptin, Iressa, or Gleevec works to stop cells from cycling and causes apoptosis activation by blocking growth and survival signaling further upstream. Finally, adding p53-MDM2 complexes displaces p53 and activates the p53 pathway, leading to cell cycle arrest and apoptosis. Many different methods can be used ...

  7. P53 p63 p73 family - Wikipedia

    en.wikipedia.org/wiki/P53_p63_p73_family

    The p53 p63 p73 family is a family of tumor suppressor genes. [1] [2] This gene family codes the proteins: p53; TP73L (also known as "p63") p73; They are sometimes considered part of a "p53 family." When overexpressed, these proteins are known to be involved in tumor pathogenesis. [3]

  9. Protein phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Protein_phosphorylation

    One such example of the regulatory role that phosphorylation plays is the p53 tumor suppressor protein. The p53 protein is heavily regulated [28] and contains more than 18 different phosphorylation sites. Activation of p53 can lead to cell cycle arrest, which can be reversed under some circumstances, or apoptotic cell death. [29]
