Summary
Hypoxia-inducible factors (HIF) traditionally sense low oxygen but now are found to regulate food intake and energy expenditure in the brain by controlling proopiomelanocortin (POMC) neurons.
Area of Science:
- Molecular Biology
- Neuroscience
- Metabolism
Background:
- Hypoxia-inducible factors (HIF) regulate cellular responses to low oxygen.
- Proopiomelanocortin (POMC) neuropeptides are key regulators of appetite and energy balance.
- Emerging evidence suggests a link between oxygen sensing and metabolic control.
Purpose of the Study:
- To explore the novel role of HIF proteins in regulating central appetite control.
- To investigate the mechanism by which HIFs influence energy expenditure.
- To connect oxygen homeostasis with nutrient sensing pathways in the brain.
Main Methods:
- Review of existing literature on HIFs and POMC.
- Discussion of experimental findings linking HIFs to POMC regulation in the brain.
- Analysis of the implications for understanding metabolic disorders.
Main Results:
- HIF proteins, beyond their role in oxygen sensing, directly impact brain circuits controlling feeding.
- HIFs regulate POMC neurons, thereby influencing food intake and energy expenditure.
- This highlights a novel intersection between hypoxia response and metabolic regulation.
Conclusions:
- HIFs represent a critical link between oxygen levels and energy homeostasis.
- Targeting HIF pathways in the brain may offer new therapeutic strategies for obesity and metabolic diseases.
- This discovery expands our understanding of how the body coordinates environmental sensing with energy balance.

01:23Diencephalon: Hypothalamus and Coordination
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...

01:30Diencephalon: Anatomical Regions
The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the subthalamic...
01:37Hypothalamic-Pituitary Axis
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.
01:17The Pituitary Gland
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.
01:27Diencephalon: Thalamus and Information Relay
The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals throughout the brain. Almost all inputs destined for the cerebral cortex, except for olfactory signals, are relayed through the thalamus. The thalamus is a sophisticated relay station, channeling information from various brain regions to the cerebral cortex, as well as a filter, prioritizing certain signals over others based on current physiological states or needs.
01:43Thermosensation
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
