Hypodermis01:02

Hypodermis

7.7K
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...

cAMP-dependent Protein Kinase Pathways01:25

cAMP-dependent Protein Kinase Pathways

7.3K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

6.0K
Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but...

Hormones of the Adrenal Glands01:31

Hormones of the Adrenal Glands

5.9K
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Overview of Lipid Metabolism01:24

Overview of Lipid Metabolism

7.0K
Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Area of Science:

  • Endocrinology
  • Metabolic Health
  • Adipose Tissue Biology

Background:

  • Androgens significantly regulate human body fat distribution and adipocyte function via the androgen receptor (AR).
  • Both androgen excess and deficiency impact metabolic health, with adipose tissue playing a key role in mediating these effects through fat distribution and adipocyte function.
  • Inconsistent research findings highlight the need to consider sex-, depot-, and organism-specific effects of androgens in adipose tissue.

Purpose of the Study:

  • To elucidate the complex role of androgens in adipose tissue, including their effects on adipocyte differentiation, function, and metabolism.
  • To investigate the mechanisms of pre-receptor androgen metabolism within adipose tissue and the enzymes involved.
  • To explore the potential of modulating local adipose androgen availability for therapeutic interventions.

Main Methods:

  • Review of existing research on androgen effects on adipocyte differentiation, insulin signaling, lipid metabolism, and adipokine production.
  • Analysis of androgen metabolism pathways in human and animal adipose tissue, focusing on key enzymes like AKR1C isoforms and 5α-reductase.
  • Examination of depot-specific and sex-specific differences in androgen action and metabolism within adipose tissue.

Main Results:

  • Androgens generally stimulate lipolysis but impair adipocyte differentiation, insulin signaling, and adipokine generation, with observed effects often being gender-specific.
  • Adipose tissue acts as a critical site for pre-receptor androgen metabolism, with enzymes AKR1C2 and AKR1C3 regulating local androgen bioavailability.
  • Androgen inactivation appears to be the predominant metabolic pathway in adipose tissue, particularly in the abdominal subcutaneous depot.

Conclusions:

  • Local androgen availability in adipose tissue is tightly controlled by specific metabolic enzymes.
  • Modulating androgen metabolism within adipose tissue presents a promising therapeutic avenue for managing metabolic disorders associated with androgen imbalance.
  • Further research is needed to fully understand the intricate regulation of androgen generation and inactivation in adipose tissue.
