Summary
Environmental obesogens, chemicals that promote obesity, are increasingly linked to the global obesity pandemic. Understanding these endocrine disruptors is crucial for developing effective prevention strategies.
Area of Science:
- Environmental Science
- Endocrinology
- Toxicology
Background:
- The global rise in obesity necessitates exploring beyond the traditional caloric model.
- Endocrine disruptors (EDs), specifically obesogens, are implicated in the pathogenesis of obesity.
- The obesogen hypothesis links increased exposure to exogenous pollutants post-WWII with the current obesity epidemic.
Discussion:
- Obesogens disrupt adipocyte development and lipid accumulation, altering metabolic balance and appetite regulation.
- Obesogens contribute to increased body fat mass through various mechanisms, including impaired adipocyte programming and altered neuroendocrine control.
- The spectrum of obesogens includes industrial chemicals, biocides, pharmaceuticals, pollutants, and smoke.
Key Insights:
- Obesogens interfere with the development and function of adipose tissue.
- These environmental chemicals can dysregulate the hormonal control of appetite and satiety.
- Scientific evidence increasingly supports the role of obesogens in contributing to obesity.
Outlook:
- Further research into obesogens and their mechanisms can inform obesity prevention.
- Translational studies are essential to elucidate the proposed mechanisms of obesogen action.
- Mitigating environmental exposure to obesogens may reduce the deleterious effects on human health and development.

Obesity
608
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Hormonal Regulation
44.1K
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Target Cell Response to Hormones
3.5K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Chemical Signaling in the Endocrine System
3.8K
A signaling cascade is a series of events that facilitates the transmission of information within or between cells, culminating in a targeted response in the recipient cell. As chemical messengers, hormones are pivotal in initiating and modulating these intricate signaling cascades based on their solubility.
Lipid-soluble hormones, such as steroid hormones, demonstrate an intracellular action. These hormones traverse cell membranes due to their lipid nature. Once inside the target cell, they...

Hormonal Control of the Ovarian Cycle
2.6K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Regulation of Hormone Secretion
4.0K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.
