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 ]
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.
Mutations of the cell pathway can either promote cell death or disallow cell death creating a huge amount of disease in the body. Mutated apoptosis pathways causing disease are plentiful and have a wide range from cancer, due to lack of apoptosome activity, Alzheimer's disease due to too much apoptosome activity, and many other ...
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 ...
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 ...

Normally, TIGAR manufactured by the body is activated by the p53 tumour suppressor protein after a cell has experienced a low level of DNA damage or stress. In some cancers, TIGAR has fallen under the control of other proteins. The hope is that future research into TIGAR will provide insight into new ways to treat cancer. [8] [9] [10]
