The regulation of COX-2, ABCA1, and ABCG1 by the lncRNA PACERR links the inflammatory response and cholesterol homeostasis.
- Open access
PACERR lncRNA regulates COX-2, ABCA1, and ABCG1, linking inflammation and cholesterol homeostasis in vascular and immune cells.
- Why it matters: Understanding how inflammation and cholesterol regulation intersect is crucial for cardiovascular disease prevention, especially since COX-2 inhibition can increase risks.
- What they did: Researchers examined PACERR expression in response to HDL and LPS, using gene silencing and interaction studies to assess its effects on key inflammatory and cholesterol-related genes.
- The result: Silencing PACERR enhances cholesterol efflux and reduces COX-2 expression and prostaglandin production, indicating its potential as a target to modulate inflammation and cholesterol balance.
