WebConclusion: In human oral cancer tissues and cells as well as Pirc rat colon, COX-1 plays an unexpectedly but more important role than COX-2 in abnormal PGE 2 production since COX-1 expression is much higher than COX-2. In addition, COX-1 expression levels are inducible in cells, and higher in polyps than surrounding mucosa in Pirc rat colon. WebThe rat tissue was removed on ice, cut into 1 mm 3 pieces and immersed in 2.5% glutaraldehyde. Then the tissue was subjected to the following procedures.
