Insights

Lipid droplet-associated hydrolase (LDAH) plays a role in childhood obesity and adipose tissue inflammation. Lower LDAH expression correlates with higher BMI SDS and increased macrophage infiltration in children.

Area of Science:

  • Adipose tissue biology
  • Obesity research
  • Human genetics

Background:

  • Lipid droplet-associated hydrolase (LDAH) is a protein found in adipose tissue with an unknown function.
  • Understanding LDAH's role is crucial for addressing obesity, particularly in children.

Purpose of the Study:

  • To investigate the function of LDAH in human adipose tissue.
  • To determine the relevance of LDAH in the context of childhood obesity.

Main Methods:

  • Analysis of LDAH variant rs13385191 and gene expression in subcutaneous adipose tissue from 296 children.
  • Studying the association between LDAH and obesity/adipose tissue biology.
  • Investigating LDAH's effect on adipogenesis in SGBS preadipocytes.

Main Results:

  • Lower LDAH expression was linked to higher BMI SDS in children.
  • Reduced LDAH expression correlated with increased macrophage infiltration in adipose tissue.
  • High LDAH expression was associated with lower circulating TNFα levels.

Conclusions:

  • LDAH appears to be involved in adipose tissue inflammation.
  • LDAH may play a role in the development of obesity in children.

Overview of Lipid Metabolism01:24

Overview of Lipid Metabolism

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...
Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
Lysosomal Hydrolases01:22

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
Lipid Digestion01:06

Lipid Digestion

Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.
Hypodermis01:02

Hypodermis

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...
Cholesterol: Significance and Regulation01:29

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...
