Insights

Mutations in tumor suppressor p53 (p53) drive cancer. This review covers FDA-approved and investigational drugs targeting p53 mutations, exploring mechanisms to suppress tumor growth.

Area of Science:

  • Oncology
  • Molecular Biology
  • Drug Discovery

Background:

  • Mutations in the tumor suppressor p53 (p53) are prevalent in approximately 50% of human cancers.
  • These mutations lead to loss of tumor suppressive functions, dominant-negative effects, and oncogenic gain-of-function activities.
  • p53 mutations are cancer-specific, making them attractive therapeutic targets.

Purpose of the Study:

  • To review clinically available FDA-approved drugs and drugs in clinical trials that target p53 mutations.
  • To summarize the mechanisms of action for these drugs.
  • To evaluate their efficacy in suppressing cancer progression.

Main Methods:

  • Literature review of FDA-approved drugs and clinical trial candidates targeting p53 mutations.
  • Analysis of drug mechanisms, including restoration of wild-type p53, rescue of nonsense mutations, degradation of mutant p53, and synthetic lethality induction.
  • Summary of drug activities against cancer progression.

Main Results:

  • Several therapeutic strategies are being investigated to target p53 mutations.
  • These strategies include restoring wild-type p53 conformation, rescuing nonsense mutations, degrading mutant p53, and exploiting synthetic lethality.
  • Drugs targeting p53 mutations show promise in suppressing cancer progression.

Conclusions:

  • Targeting p53 mutations represents a promising strategy in cancer therapy.
  • A range of therapeutic approaches are under investigation, with several drugs in clinical trials.
  • Further research and clinical development are crucial to fully realize the therapeutic potential of targeting p53 mutations.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Abnormal Proliferation02:23

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...

Drugs that Stabilize Microtubules01:15

Drugs that Stabilize Microtubules

Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

DNA Damage can Stall the Cell Cycle02:37

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...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
