POMC neuronal heterogeneity in energy balance and beyond: an integrated view

open access: yesNature Metabolism, 2021
Hypothalamic AgRP and POMC neurons are conventionally viewed as the yin and yang of the body's energy status, since they act in an opposite manner to modulate appetite and systemic energy metabolism. However, although AgRP neurons' functions are comparatively well understood, a unifying theory of how POMC neuronal cells operate has remained elusive ...

5-ht inhibition of rat insulin 2 promoter cre recombinase transgene and proopiomelanocortin neuron excitability in the mouse arcuate nucleus [PDF]

open access: yes, 2009
A number of anti-obesity agents have been developed that enhance hypothalamic 5-HT transmission. Various studies have demonstrated that arcuate neurons, which express proopiomelanocortin peptides (POMC neurons), and neuropeptide Y with agouti-related ...

Selective Restoration ofPomcExpression in Glutamatergic POMC Neurons: Evidence for a Dynamic Hypothalamic Neurotransmitter Network [PDF]

open access: yeseneuro, 2019
AbstractHypothalamic POMC deficiency leads to obesity and metabolic deficiencies, largely due to the loss of melanocortin peptides. However, POMC neurons in the arcuate nucleus (ARC) are comprised of glutamatergic and GABAergic subpopulations. The developmental program, relative proportion and function of these two subpopulations are unresolved.

Unveiling the transcriptome alteration of POMC neuron in diet-induced obesity [PDF]

open access: yesExperimental Cell Research, 2019
Abstract Background: Loss of neuron homeostasis in the Arcuate nucleus (ARC) is suggested to be responsible for the development diet-induced-obesity (DIO). We previously reported that loss of Rb1 gene compromised the homeostasis of anorexigenic POMC neurons in ARC and induced obesity in mice.Method: To shed light on how DIO develops, we propose

Steroid receptor coactivator-1 modulates the function of Pomc neurons and energy homeostasis. [PDF]

open access: yes, 2019
Hypothalamic neurons expressing the anorectic peptide Pro-opiomelanocortin (Pomc) regulate food intake and body weight. Here, we show that Steroid Receptor Coactivator-1 (SRC-1) interacts with a target of leptin receptor activation, phosphorylated STAT3,

Hypothalamic Proopiomelanocortin Is Necessary for Normal Glucose Homeostasis in Female Mice

open access: yesFrontiers in Endocrinology, 2018
The arcuate nucleus of the hypothalamus is a key regulator of energy balance and glucose homeostasis. In particular, arcuate proopiomelanocortin (POMC) neurons inhibit food intake, stimulate energy expenditure and increase glucose tolerance.

Glucose regulates the effects of leptin on hypothalamic POMC neurons. [PDF]

open access: yes, 2016
Leptin is believed to exert its potent appetite-suppressing effects via stimulation of hypothalamic anorexigenic proopiomelanocortin (POMC)-containing neurons and inhibition of orexigenic agouti-related protein (AgRP) neurons.

A Novel NR3C1 Frameshift Variant Associated With Familial Glucocorticoid Resistance Syndrome: An Integrated Analysis of Steroid Profiling and Structural Modeling

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Glucocorticoid resistance syndrome (GRS) is a rare hereditary disorder caused by pathogenic variants in NR3C1, characterized by marked phenotypic heterogeneity and frequent misdiagnosis as primary aldosteronism or subclinical Cushing's syndrome.

Pretreatment Cachexia Index Is Associated With Severe Treatment Toxicity and Overall Survival in HPV‐Negative Head and Neck Squamous Cell Carcinoma

open access: yesHead &Neck, EarlyView.
ABSTRACT Introduction Cancer cachexia is characterized by skeletal muscle loss, poor nutrition, and systemic inflammation and is common in head and neck cancer. We evaluated whether the Cachexia Index (CXI) predicts treatment toxicity and survival in HPV‐negative HNSCC.
