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 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]
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.
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.
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 ...
The connectome will significantly increase our understanding of how functional brain states emerge from their underlying structural substrate, and will provide new mechanistic insights into how brain function is affected if this structural substrate is disrupted. [4] In his 2005 Ph.D. thesis, From diffusion MRI to brain connectomics, Hagmann wrote:
For example, the p53 knockout mouse is named after the p53 gene which codes for a protein that normally suppresses the growth of tumours by arresting cell division and/or inducing apoptosis. Humans born with mutations that deactivate the p53 gene have Li-Fraumeni syndrome , a condition that dramatically increases the risk of developing bone ...
The brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
