How cholesterol and the SR-BI receptor affect fat cells

A novel role of cholesterol and SR-BI in adipocyte biology

NIH-funded research Ut Southwestern Medical Center · NIH-11169944

Researchers are looking at whether HDL cholesterol and the SR-BI protein change how fat cells store triglycerides, which could matter for people at risk of obesity.

What this research studies

This project uses mice engineered to lack SR-BI in their fat cells to see how that changes fat cell size and fat storage. Lab-grown human fat cells will be studied to learn how HDL cholesterol and SR-BI affect the genes that control lipid handling. The team will use modern DNA-access methods to see which genes are turned on or off in fat cells. They will also search human genetic data to find whether differences in SR-BI might influence obesity risk.

Who could benefit from this research

Good fit: Adults willing to provide adipose tissue samples or genetic information, including people with obesity or differing body fat levels, would be best suited to contribute.

Not a fit: People without obesity or metabolic concerns and anyone unwilling to donate tissue or genetic data are unlikely to receive direct benefit from participating.

Why it matters

Potential benefit: If successful, this could point to new ways to reduce fat storage in fat cells and lead to treatments or prevention strategies for obesity.

How similar studies have performed: Prior animal and cell studies link SR-BI and HDL to fat cell cholesterol and lipid metabolism, but translating those findings to human obesity remains relatively new.
