Summary
The p53 tumor suppressor protein
Area of Science:
- Oncology
- Molecular Biology
- Epigenetics
Background:
- The p53 protein is a crucial tumor suppressor involved in cellular stress responses.
- Its functions include cell cycle arrest and apoptosis, often through transcriptional regulation.
- Some p53 activities occur independently of transcription.
Purpose of the Study:
- To review recent advances in understanding p53 post-translational modifications (PTMs).
- To explore how p53 PTMs function as epigenetic-like codes.
- To discuss the role of PTM deregulation in tumorigenesis.
Main Methods:
- Literature review of recent research on p53 post-translational modifications.
- Analysis of the functional impact of these modifications in vivo.
- Discussion of the link between PTMs, genetic data interpretation, and p53 functions.
Main Results:
- A wide spectrum of p53 PTMs modulates its functions.
- These modifications act as epigenetic-like codes influencing p53 activity.
- Deregulation of p53 PTMs is implicated in cancer development.
Conclusions:
- Understanding p53 PTMs is critical for cancer research.
- Future research should focus on PTMs, genetic data interpretation, and p53's unconventional roles.
- p53 regulates metabolism, autophagy, and other tumor suppressor activities beyond traditional pathways.

Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Covalently Linked Protein Regulators
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein.

Negative Regulator Molecules
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.
DNA Damage can Stall the Cell Cycle
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
