  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. TP53-inducible glycolysis and apoptosis regulator - Wikipedia

    en.wikipedia.org/wiki/TP53-inducible_glycolysis...

    The TP53-inducible glycolysis and apoptosis regulator (TIGAR) also known as fructose-2,6-bisphosphatase TIGAR is an enzyme that in humans is encoded by the C12orf5 gene. [ 5 ] [ 6 ] [ 7 ] TIGAR is a recently discovered enzyme that primarily functions as a regulator of glucose breakdown in human cells .

  6. DNA damage (naturally occurring) - Wikipedia

    en.wikipedia.org/wiki/DNA_damage_(naturally...

    High-normal levels of the bile acid deoxycholic acid cause apoptosis in human colon cells, [56] but may also lead to colon cancer if repair and apoptotic defenses are insufficient. [57] Apoptosis serves as a safeguard mechanism against tumorigenesis. [58] It prevents the increased mutagenesis that excess DNA damage could cause, upon replication ...

  7. Apoptosis-inducing factor - Wikipedia

    en.wikipedia.org/wiki/Apoptosis-inducing_factor

    Apoptosis inducing factor is involved in initiating a caspase-independent pathway of apoptosis (positive intrinsic regulator of apoptosis) by causing DNA fragmentation and chromatin condensation. Apoptosis inducing factor is a flavoprotein. [2] It also acts as an NADH oxidase. Another AIF function is to regulate the permeability of the ...

  8. 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 ...

  9. Protein phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Protein_phosphorylation

    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] This activity occurs only in situations wherein the cell is damaged or physiology is disturbed in normal healthy ...
