Insights

Folic acid may prevent neural tube defects, but its mechanism remains unclear for many cases. Myo-inositol shows promise as a complementary therapy for folate-resistant defects.

Area of Science:

  • Developmental biology
  • Genetics
  • Nutritional science

Background:

  • Neural tube defects (NTDs) are congenital abnormalities with significant public health impact.
  • Folic acid is known to prevent NTDs, but the underlying metabolic mechanisms are not fully understood.
  • A subset of NTDs (~30%) is resistant to folic acid intervention.

Purpose of the Study:

  • To investigate the unclear mechanism of folic acid in preventing neural tube defects.
  • To explore myo-inositol as a potential complementary therapeutic strategy for folate-resistant NTDs.
  • To leverage genetic models for identifying the basis of human NTDs.

Main Methods:

  • Analysis of folate-related enzymes in embryos during neurulation.
  • Evaluation of myo-inositol administration in mouse genetic models of NTDs.
  • Utilizing known mouse genes associated with NTDs to identify genetic causes.

Main Results:

  • Current studies on folate-related enzymes have not identified the precise metabolic defect corrected by folic acid.
  • Mouse genetic models suggest myo-inositol may offer a complementary approach for specific NTDs.
  • A substantial number of mouse genes linked to NTDs exist, offering a resource for human genetic studies.

Conclusions:

  • The exact mechanism by which folic acid prevents neural tube defects requires further elucidation.
  • Myo-inositol presents a potential therapeutic avenue for folate-resistant neural tube defects.
  • Mouse genetic models are valuable tools for uncovering the genetic etiology of human NTDs.

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
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.

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Biosynthesis of Nucleic Acids01:28

Biosynthesis of Nucleic Acids

Nucleic acid biosynthesis is a fundamental biochemical process that produces the purine and pyrimidine nucleotides essential for DNA and RNA synthesis. This pathway maintains a balanced nucleotide pool, preventing imbalances that could jeopardize genetic integrity and cellular function. Given the crucial role of nucleotides, their synthesis is tightly regulated to ensure proper cellular homeostasis.Purine BiosynthesisThe biosynthesis of purine nucleotides begins with ribose-5-phosphate, a...
