Insights

Ornithine decarboxylase (ODC) is a known cancer target. New research shows spermidine synthase, an enzyme in polyamine metabolism, is activated by the MYC gene and may prevent B-cell lymphomas.

Area of Science:

  • Biochemistry and Molecular Biology
  • Cancer Research
  • Oncology

Background:

  • Ornithine decarboxylase (ODC) has been a long-standing target for cancer chemoprevention and chemotherapy.
  • Polyamines are crucial for cell growth and proliferation, and their metabolism is often dysregulated in cancer.

Discussion:

  • This study identifies spermidine synthase, an enzyme in the polyamine pathway, as a novel target.
  • Evidence suggests spermidine synthase is transactivated by the MYC gene, a known oncogene implicated in various cancers.

Key Insights:

  • Spermidine synthase represents a potential therapeutic target for cancer chemoprevention.
  • Targeting spermidine synthase may be particularly effective for B-cell lymphomas, given the MYC gene's role.

Outlook:

  • Further research into the MYC-spermidine synthase interaction could reveal new chemoprevention strategies.
  • Exploring inhibitors of spermidine synthase may offer a novel approach to treating B-cell malignancies.

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 specific...

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...
Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

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...
