  2. 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.

  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 - 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 ]

  5. Apoptosis - Wikipedia

    en.wikipedia.org/wiki/Apoptosis

    Part of this pathway includes alpha-interferon and beta-interferon, which induce transcription of the p53 gene, resulting in the increase of p53 protein level and enhancement of cancer cell-apoptosis. [85] p53 prevents the cell from replicating by stopping the cell cycle at G1, or interphase, to give the cell time to repair; however, it will ...

  6. BH3 interacting-domain death agonist - Wikipedia

    en.wikipedia.org/wiki/BH3_interacting-domain...

    The expression of BID is upregulated by the tumor suppressor p53, and BID has been shown to be involved in p53-mediated apoptosis. [7] The p53 protein is a transcription factor that, when activated as part of the cell's response to stress, regulates many downstream target genes, including BID. However, p53 also has a transcription-independent ...

  7. 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.

  8. Cellular senescence - Wikipedia

    en.wikipedia.org/wiki/Cellular_senescence

    This suggests that p53 pathway could be effectively harnessed as a therapeutic intervention to trigger senescence and ultimately mitigate tumorigenesis. [4] p53 has been shown to have promising therapeutic relevance in an oncological context. In the 2007 Nature paper by Xue et al., RNAi was used to regulate endogenous p53 in a liver carcinoma ...

  9. Survivin - Wikipedia

    en.wikipedia.org/wiki/Survivin

    This same effect was not seen in T47D cells that carry mutant inactive p53. [17] P53's normal function is to regulate genes that control apoptosis. As survivin is a known inhibitor of apoptosis, it can be implied that p53 repression of survivin is one mechanism by which cells can undergo apoptosis upon induction by apoptotic stimuli or signals.
