Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Regulation of Food Intake01:30

Regulation 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...

Gene-Environment Interactions01:20

Gene-Environment Interactions

270
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

3.3K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.
Humoral...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

316
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

3.0K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Area of Science:

  • Reproductive Endocrinology
  • Genetics
  • Neuroendocrinology

Background:

  • Functional hypothalamic amenorrhea (FHA) is a frequent cause of amenorrhea and anovulation in young women.
  • It is often triggered by stressors like calorie restriction, excessive exercise, and psychosocial stress.
  • These factors disrupt gonadotropin-releasing hormone secretion, causing hypoestrogenism and health issues.

Purpose of the Study:

  • To review recent genetic findings on FHA pathophysiology.
  • To explore the potential genetic predisposition influencing FHA development.
  • To raise awareness regarding a possible male counterpart to FHA.

Main Methods:

  • Narrative review of existing literature.
  • Analysis of genetic evidence related to FHA.
  • Examination of studies on idiopathic hypogonadotropic hypogonadism and FHA.

Main Results:

  • Genetic predisposition plays a role in FHA, explaining varied stress responses.
  • Rare gene variants linked to hypogonadotropic hypogonadism are found in FHA patients.
  • Preliminary data suggests a potential FHA equivalent in men.

Conclusions:

  • FHA is a complex condition influenced by genetics, environment, and epigenetics.
  • Genetic susceptibility may increase vulnerability to FHA triggers.
  • Further research is needed to confirm and characterize a male form of FHA.
