High fat programming of beta cell compensation, exhaustion, death and dysfunction

Area of Science:

• Metabolic programming
• Developmental origins of health and disease (DOHaD)

Background:

• Programming refers to critical developmental events impacting progeny health.
• Fetal and lactational programming are potent due to islet plasticity.
• High-fat (HF) programming alters progeny metabolism and physiology, inducing diabetogenic phenotypes.

Purpose of the Study:

• To explore the impact of high-fat (HF) programming on metabolic health.
• To understand the mechanisms of beta cell dysfunction induced by HF programming.
• To highlight the importance of early nutritional interventions.

Main Methods:

• The study defines and discusses concepts of developmental programming, including fetal, lactational, and postnatal stages.
• It examines the effects of high-fat diets (HFD) during critical developmental windows.
• The abstract describes the physiological consequences of HF programming on beta cells and insulin resistance.

Main Results:

• HF programming induces variable diabetogenic phenotypes dependent on timing and duration.
• Maternal obesity exacerbates HF programming effects.
• HF programming leads to beta cell compensation, exhaustion, death, and dysfunction, often co-occurring with insulin resistance.

Conclusions:

• Balanced nutrition during developmental windows is crucial for preserving beta cell structure and function.
• Early positive nutritional interventions can mitigate the risk of diabetes and metabolic disease.
• Understanding programming is key to preventing long-term metabolic disorders.
