Growth Hormone's Effect on Adipose Tissue: Quality versus Quantity.

Area of Science:

• Endocrinology
• Metabolic Research
• Obesity Science

Background:

• Obesity, characterized by excessive adipose tissue (AT) expansion, is a major public health concern.
• Adipose tissue is more complex than previously understood, necessitating nuanced efficacy measures beyond absolute mass reduction.
• Growth hormone (GH) has lipolytic effects beneficial for reducing AT mass and preserving lean body mass.

Purpose of the Study:

• To review the complexities of adipose tissue in relation to growth hormone (GH) action.
• To summarize current understanding of GH's influence on adipose tissue using human and mouse data.
• To discuss the therapeutic potential of GH or GH antagonists in obesity management.

Main Methods:

• Literature review of recent complexities in adipose tissue biology.
• Analysis of existing human and mouse data on GH and adipose tissue interaction.
• Synthesis of information regarding therapeutic applications and knowledge gaps.

Main Results:

• Adipose tissue is highly dynamic, requiring more than mass reduction to assess therapeutic efficacy.
• GH exhibits potent lipolytic effects but also possesses anti-insulin activities.
• Concerns exist regarding GH's potential role in promoting certain cancers.

Conclusions:

• Therapeutic strategies targeting GH action may be beneficial for obesity and metabolic dysfunction.
• Understanding the complex interplay between GH and adipose tissue is crucial for developing effective obesity treatments.
• Further research is needed to address knowledge gaps concerning GH and adipose tissue in obesity.
