Summary
Maternal nutrition during pregnancy can program adult obesity risk by altering offspring
Area of Science:
- Developmental Biology
- Metabolic Syndrome
- Nutritional Epigenetics
Background:
- Global rise in adult and childhood obesity rates.
- Evidence suggests intrauterine and early postnatal environments program adult metabolic disorders.
- Concept of "fetal programming of adult disease" supported by nutritional studies.
Purpose of the Study:
- Review the impact of maternal nutrition on programming offspring's obesity risk.
- Focus on changes in hypothalamic appetite-regulating circuits.
- Explore epigenetic mechanisms linking maternal diet to later-life obesity.
Main Methods:
- Analysis of animal models of maternal under- and over-nutrition.
- Examination of experimental evidence on hypothalamic circuit development.
- Discussion of epigenetic modifications affecting gene expression.
Main Results:
- Maternal nutritional insults during critical developmental periods perturb hypothalamic circuits.
- These perturbations lead to permanent changes affecting appetite and energy expenditure.
- Epigenetic modifications are identified as key molecular mediators.
Conclusions:
- Maternal diet plays a crucial role in fetal programming of obesity.
- Hypothalamic epigenetic programming links maternal nutrition to offspring's metabolic health.
- Understanding these mechanisms can inform preventative strategies against obesity.

01:30Regulation of Food Intake
3.2K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

01:19Energy Balance
1.5K
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

5.3K
The hypothalamus is a small yet highly complex and essential brain region that plays a crucial role in regulating various bodily functions. Anatomically, it is located at the base of the brain, just above the brainstem and below the thalamus, forming part of the limbic system.
The hypothalamus interacts with other brain regions, including the pituitary gland, through a direct physical connection called the hypothalamic-pituitary axis. The hypothalamus receives somatic and visceral inputs and...

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

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.
