Summary
MicroRNAs (miRNAs) are key regulators of gene expression. This review highlights their crucial role in hypothalamic neurons for controlling appetite and whole-body energy balance.
Area of Science:
- Neuroscience
- Metabolism Research
- Molecular Biology
Background:
- The hypothalamus regulates appetite, body weight, and metabolism through diverse neuronal types.
- Gene expression in hypothalamic neurons is modulated by hormonal and nutritional signals.
- Mechanisms controlling these neuronal gene programs in health and disease remain incompletely understood.
Purpose of the Study:
- To review current evidence on the role of microRNAs (miRNAs) in hypothalamic neurons.
- To explore the involvement of miRNAs in appetite and energy balance control.
Main Methods:
- Literature review of existing research on miRNAs and hypothalamic function.
- Analysis of studies investigating miRNA regulation of gene expression in the hypothalamus.
- Synthesis of findings linking miRNAs to systemic metabolism.
Main Results:
- MicroRNAs (miRNAs) are identified as critical regulators of gene expression.
- Emerging evidence points to miRNAs as pivotal modulators of systemic metabolism.
- miRNAs within hypothalamic neurons are implicated in appetite and energy balance.
Conclusions:
- Hypothalamic miRNAs play a significant role in regulating appetite and energy homeostasis.
- Further research into miRNA mechanisms in the hypothalamus is warranted for understanding metabolic disorders.
- Targeting miRNAs could offer novel therapeutic strategies for metabolic diseases.

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

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...

12.5K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

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...
