Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

7.5K
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.

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

2.7K
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...

Testosterone: Functions and Regulation

2.9K
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...

Hormonal Regulation of Blood Pressure

7.2K
Endocrinal or hormonal intervention in the cardiovascular system is predominantly exerted by the catecholamines - epinephrine and norepinephrine, as well as a slew of hormones that interact with renal function to modulate blood volume.
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction...

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

6.2K
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...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

2.2K
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...

Summary

Benign prostatic hyperplasia (BPH) involves prostate cell growth influenced by hormones and growth factors. Inflammation and hormonal imbalances, like hypogonadism, contribute to BPH development and lower urinary tract symptoms.

Area of Science:

  • Urology
  • Andrology
  • Cell Biology

Background:

  • Benign prostatic hyperplasia (BPH) is a common condition in aging men.
  • Androgens, growth factors (IGF, FGF, TGF), and their interactions are crucial for prostate homeostasis.
  • Alterations in these factors disrupt the balance between cell proliferation and death, contributing to BPH.

Purpose of the Study:

  • To review the etio-pathogenesis of benign prostatic hyperplasia (BPH).
  • To explore the role of hormonal and inflammatory factors in BPH development.
  • To understand the mechanisms leading to lower urinary tract symptoms (LUTS) in BPH patients.

Main Methods:

  • Literature review of experimental studies on BPH pathogenesis.
  • Analysis of the interplay between growth factors, androgens, and prostate cells.
  • Examination of the role of inflammation and hormonal abnormalities in BPH.

Main Results:

  • Androgens and growth factors are essential for prostate cell differentiation and proliferation.
  • Disrupted interactions between growth factors and hormones can lead to BPH.
  • Chronic inflammation, often linked to hormonal imbalances like hypogonadism, plays a significant role in BPH onset.

Conclusions:

  • BPH pathogenesis is multifactorial, involving complex interactions between hormonal milieu, growth factors, and inflammation.
  • Hypogonadism and associated prostate inflammation are implicated in BPH development.
  • Further research is needed to fully elucidate the mechanisms underlying BPH and LUTS.
