Gene-Environment Interactions

Gene-Environment Interactions

Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Epigenetic Regulation

Epigenetic Regulation

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

Epigenetic Regulation

Epigenetic Regulation

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.

An Overview of the Endocrine System

An Overview of the Endocrine System

The endocrine system, a complex network of glands, orchestrates physiological balance within the body through the production and secretion of hormones. These hormones are chemical messengers in intercellular communication, acting as conduits between the secretory cells and distant target sites. They traverse the circulatory system by being released into the extracellular fluid, and their impact is specific to cells possessing receptors for a particular hormone.
The endocrine system collaborates...

The Endocrine System

The Endocrine System

The endocrine system is an extensive network of glands – organs or tissues in the body that create chemicals that control many bodily functions, that secrete hormones, which are chemical messengers that play essential roles in regulating various bodily functions. These hormones are secreted into the bloodstream and travel throughout the body. They require specific receptors to convey signals to cells possessing these corresponding receptors. This complex signaling mechanism ensures that every...

Area of Science:

Endocrinology
Epigenetics
Genetics

Background:

Genetics alone cannot fully explain endocrine phenotype variability and environmental responsiveness.
Epigenetics offers a mechanism linking genetics and environment to endocrine function.
Epigenetic mechanisms (DNA methylation, histone modification, microRNA) create phenotype plasticity.

Purpose of the Study:

To review the role of epigenetics in endocrine function regulation.
To discuss epigenetic mechanisms in hormone action and endocrine disruptors.
To propose a model explaining endocrine changes across the lifespan and in populations.

Main Methods:

Review of current understanding of epigenetics in endocrinology.
Discussion of epigenetic regulation at three levels of hormone action.
Examination of epigenetic effects of endocrine disruptors and hormones.

Main Results:

Epigenetics regulates hormone synthesis, release, levels, and target-organ responsiveness.
Environmental factors and developmental stages influence epigenetic modifications.
A three-dimensional model (genetics, environment, development) explains endocrine variability.

Conclusions:

Identifying plasticity genes responding to environmental stimuli is crucial for understanding epigenetics in endocrinology.
Investigating the heritability and reversibility of epigenetic changes is vital for endocrine disorder prevention and treatment.
Epigenetics provides a framework for understanding endocrine plasticity and disease origins.
