Summary
Functional hypothalamic amenorrhea (FHA) is a common cause of infertility linked to low energy availability. Kisspeptin neurons regulate reproductive hormones and may offer new treatments for FHA.
Area of Science:
- Reproductive Endocrinology
- Neuroendocrinology
- Metabolic Regulation
Background:
- Functional hypothalamic amenorrhea (FHA) is a prevalent condition causing anovulation, infertility, and low estrogen.
- FHA involves suppressed pulsatile gonadotropin-releasing hormone (GnRH) release, leading to hypogonadotropic hypogonadism.
- It arises from low energy availability (diet, exercise) and stress, potentially influenced by genetic factors.
Purpose of the Study:
- To review the physiological regulation of GnRH pulsatility by kisspeptin.
- To explore how energy status signals modulate kisspeptin neurons and reproductive function.
- To discuss the role of kisspeptin in FHA pathophysiology and its therapeutic potential.
Main Methods:
- Review of physiological regulation of GnRH secretion.
- Analysis of kisspeptin neuron modulation by energy status signals.
- Exploration of endocrine factors in FHA and kisspeptin's role.
Main Results:
- Kisspeptin is a key regulator of the GnRH pulse generator.
- Hypothalamic kisspeptin neurons integrate signals of energy status.
- Kisspeptin neurons are a likely final common pathway for GnRH suppression in FHA.
Conclusions:
- Kisspeptin plays a central role in regulating reproductive function.
- Dysregulation of kisspeptin signaling contributes to FHA.
- Kisspeptin-based therapies hold promise for treating FHA.

01:30Regulation of Food Intake
204
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...

01:24Glucagon-like Receptor Agonists
305
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

01:27Major Hormones and Their Functions
347
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

01:28Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
153
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...

01:27Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
1.2K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.

01:22PI3K/mTOR/AKT Signaling Pathway
3.4K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...
