Genome-wide regulation of electro-acupuncture on the neural Stat5-loss-induced obese mice

Area of Science:

• Neuroscience and Metabolism
• Genomics and Molecular Biology

Background:

• Obesity is a complex metabolic disorder with unclear underlying mechanisms.
• Acupuncture is a traditional therapy suggested to aid in managing obesity-related conditions, but its molecular basis remains largely unknown.

Purpose of the Study:

• To investigate the molecular mechanisms by which electro-acupuncture (EA) influences obesity.
• To identify genomic networks affected by EA in a mouse model with a specific genetic predisposition to obesity.

Main Methods:

• Utilized a mouse model with neuron-specific deletion of the transcription factor STAT5 (Stat5NKO), which exhibits obesity.
• Applied electro-acupuncture (EA) to obese Stat5NKO mice.
• Employed RNA sequencing (RNA-seq) to analyze gene expression changes in the hypothalamus and epididymal white adipose tissue (Epi-WAT).

Main Results:

• EA treatment significantly reduced body weight and the ratio of epididymal white adipose tissue (Epi-WAT) to body weight in obese mice.
• EA decreased plasma levels of glucose, triglyceride, and cholesterol.
• EA enhanced cold endurance and reversed aberrant gene expression patterns in the hypothalamus and Epi-WAT of Stat5NKO mice.

Conclusions:

• This research elucidates the genomic networks involved in obesity and how EA modulates them.
• The findings provide novel insights into the molecular mechanisms underlying acupuncture-induced weight loss and metabolic improvements.
