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 absence of p21 or 14-3-3 cannot sufficiently inhibit the CyclinB-Cdc2 complex, thus exhibiting the regulatory control of p53 and p21 in the G2 checkpoint in response to DNA damage. [12] p53 mutations can result in a significant checkpoint deficit, which has important implications in the treatment of cancer.
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.
Akt is activated downstream of vascular endothelial growth factor (VEGF) in endothelial cells in the lining of blood vessels, promoting survival and growth. Akt also contributes to angiogenesis by activating endothelial nitric oxide synthase (eNOS), which increases production of nitric oxide (NO).

p53 can be activated in response to a wide variety of cellular stressors, both oncogenic and non-oncogenic. An important checkpoint in a complex pathway, activated p53 has been shown to bind DNA and transcriptionally regulate genes that can mediate a variety of cellular growth processes including DNA repair , growth arrest, cellular senescence ...
