Bisphenol A changes brown fat by causing cell death, fat buildup, and inflammation

BPA exposure for six weeks led to reduced brown adipose tissue mass in male mice.

• The reduction in brown adipose tissue was associated with increased cell death and the transformation of brown fat into white fat.
• Brown adipocytes exhibited characteristics of stress, including larger cell size, lower nuclear density, and decreased mitochondrial DNA content.
• Increased expression of fat-forming markers was observed, indicating a shift towards white adipose tissue characteristics.
• BPA exposure triggered inflammation and oxidative stress, contributing to the observed cellular changes.
• These findings suggest specific mechanisms by which BPA may remodel brown adipose tissue, warranting further investigation into its effects on human adipose health.
