19531467-12	2009	Our data demonstrate for the first time that PGN activates the nSMase/ceramide pathway to induce MKK3/6/p38 MAPK activation, which in turn initiates NF-kappaB activation and ultimately induces COX-2 expression in macrophages.	Ceramides	70-78	mitogen-activated protein kinase kinase 3	Homo sapiens	97-103
