MATERIALS AND METHODS: Western blotting was used to examine the effect of apigenin (10-40 microM) on the LPS- and nicotine-induced expression of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and heme oxygenase-1 (HO-1), as well as the phosphorylation of mitogen-activated protein kinases (MAPKs), in hPDL cells.

In order to explain the mechanism of nicotine-induced endothelium dysfunction, we investigated the effects of nicotine on cyclooxygenase-2 (COX-2) and intercellular adhesion molecule-1 (ICAM-1) expression in human umbilical vein endothelial cells (HUVECs).

To clarify the mechanism of the effect of nicotine, mRNA levels of cyclooxygenase-2 (COX-2), interleukin (IL)-1beta, IL-6 and inducible nitric oxide synthase (iNOS) and protein expression of COX-2 and iNOS in the necrotic area were investigated by real-time reverse transcription-polymerase chain reaction and Western blotting, respectively.

In addition, treatment with nicotine could induce COX-2, PGE (2), and IL-6 generation in in vivo and in vitro studies.
Cyclooxygenase-2 (COX-2) and prostaglandin E (2) (PGE (2)) have been shown to play critical roles in respiratory inflammation.
