Abstract:
As a nuclear receptor, peroxisome proliferator-activated receptor-δ (PPARδ) plays a critical role in regulating inflammation and cancer, while it is still unclear the mechanism of PPARδ agonist GW501516 on colitis-associated colorectal cancer. Here we found that GW501516 significantly enhanced colitis-associated colorectal cancer in AOM/DSS-induced mice. In addition, PPARδ agonist GW501516 enhanced pro-inflammatory gene expressions (COX-2, IL-6, IL-8 and MCP-1) in inflamed colon. Further analysis showed that GW501516 increased the expressions of Glut1 and SLC1A5 in colon cancer cells as well as AOM/DSS-induced colorectal tumors. These findings revealed a new mechanism of PPARδ agonist GW501516-mediated colitis-associated colorectal cancer.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
