Kisspeptin Neurons in the Arcuate Nucleus of the Hypothalamus Orchestrate Circadian Rhythms and Metabolism [PDF]

Current Biology, 2019
Successful reproduction in female mammals is precisely timed and must be able to withstand the metabolic demand of pregnancy and lactation. We show that kisspeptin-expressing neurons in the arcuate hypothalamus (Kiss1ARH) of female mice control the daily timing of food intake, along with the circadian regulation of locomotor activity, sleep, and core ...

Short photoperiod-induced decrease of histamine H3 receptors facilitates activation of hypothalamic neurons in the Siberian Hamster [PDF]

, 2009
Nonhibernating seasonal mammals have adapted to temporal changes in food availability through behavioral and physiological mechanisms to store food and energy during times of predictable plenty and conserve energy during predicted shortage.

The hypothalamus as the central regulator of energy balance and its impact on current and future obesity treatments [PDF]

Archives of Endocrinology and Metabolism
The hypothalamus is a master regulator of energy balance in the body. First-order hypothalamic neurons localized in the arcuate nucleus sense systemic signals that indicate the energy stores in the body.

Deoxyribonucleic Acid Microarray Analysis of Gene Expression Pattern in the Arcuate Nucleus/Ventromedial Nucleus of Hypothalamus during Lactation [PDF]

Endocrinology, 2005
Lactation is characterized by extreme hyperphagia and negative energy balance resulting from a large energy drain due to milk production and by a suppression of cyclic ovarian function. Increases in neuropeptide Y and agouti-related protein and a decrease in proopiomelanocortin expression in the arcuate nucleus of hypothalamus (ARH) may contribute to ...

Control by the brain of vitamin A homeostasis

iScience, 2023
Summary: Vitamin A is a micronutrient essential for vertebrate animals maintained in homeostatic balance in the body; however, little is known about the control of this balance.

Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]

, 2016
Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...

Chronic high-fat diet induces overeating and impairs synaptic transmission in feeding-related brain regions

Frontiers in Molecular Neuroscience, 2022
Obesity is linked to overeating, which can exacerbate unhealthy weight gain. However, the mechanisms for mediating such linkages are elusive. In the current study, we hypothesized that synaptic remodeling occurs in feeding-related brain regions of obese ...

Substance P regulates puberty onset and fertility in the female mouse [PDF]

, 2015
Puberty is a tightly regulated process that leads to reproductive capacity. Kiss1 neurons are crucial in this process by stimulating GnRH, yet how Kiss1 neurons are regulated remains unknown. Substance P (SP), an important neuropeptide in pain perception,
