Epigenetic Regulation01:46

Epigenetic Regulation

33.9K
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Epigenetic Regulation

3.9K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Fetal Circulation01:14

Fetal Circulation

3.1K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Combination Therapies and Personalized Medicine

6.2K
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...

Lewis Acids and Bases02:33

Lewis Acids and Bases

48.5K
In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Area of Science:

  • Developmental biology
  • Genetics
  • Public Health

Background:

  • The developmental origins of health and disease (DOHaD) theory posits that early-life environmental exposures impact adult health.
  • Epigenetics, modifications to DNA without altering the sequence, plays a crucial role in mediating these effects.
  • Fetal exposure to stressors like malnutrition or mental stress can lead to long-term health issues and even be passed to offspring.

Purpose of the Study:

  • To explore the link between fetal environmental stress, epigenetic alterations, and the development of adult diseases.
  • To highlight the reversibility of epigenetic modifications and their therapeutic potential.
  • To underscore the possibility of preventive and preemptive medicine for DOHaD-related disorders.

Main Methods:

  • Review of existing scientific literature on DOHaD and epigenetics.
  • Analysis of evidence linking fetal stress to epigenetic changes and disease phenotypes.
  • Examination of studies on the reversibility of epigenetic modifications and treatment efficacy.

Main Results:

  • Environmental stress during fetal development can induce lasting epigenetic dysregulation.
  • These epigenetic alterations are associated with increased risk for cardiovascular, metabolic, and neurodevelopmental disorders later in life.
  • Evidence suggests epigenetic modifications can be transmitted across generations.

Conclusions:

  • Epigenetic modifications induced by early-life stress are reversible and potentially treatable.
  • This reversibility opens avenues for preventive and preemptive medical interventions.
  • Targeting epigenetic mechanisms offers a promising strategy for mitigating DOHaD-related health consequences.
