21251952-0	2011	HT-29 colorectal cancer cells undergoing apoptosis overexpress COX-2 to delay ursolic acid-induced cell death.	ursolic acid	78-90	prostaglandin-endoperoxide synthase 2	Homo sapiens	63-68	
21251952-4	2011	In this study, we focused our interest on the role played by COX-2 in apoptosis induced in HT-29 human colorectal cancer cells by ursolic acid (UA), a triterpenoid found in a large variety of plants.	ursolic acid	130-142	prostaglandin-endoperoxide synthase 2	Homo sapiens	61-66	
21251952-4	2011	In this study, we focused our interest on the role played by COX-2 in apoptosis induced in HT-29 human colorectal cancer cells by ursolic acid (UA), a triterpenoid found in a large variety of plants.	ursolic acid	144-146	prostaglandin-endoperoxide synthase 2	Homo sapiens	61-66	
21251952-8	2011	These results demonstrated that COX-2 was involved in a resistance mechanism to UA-induced apoptosis in HT-29 cells.	ursolic acid	80-82	prostaglandin-endoperoxide synthase 2	Homo sapiens	32-37
