| Research Abstract |
Nicotine in a cigarette smoke makes a production of stress-responsive protein chromogranin A(CgA) due to periodontal ligament fibers blast cells increase.
Particularly, expression levels of higher CgA increased under a passive smoking condition as compared with an active smoking.We suggested the possibility that stress was involved in a response of the periodontium.We conducted the functional analysis of the associated gene cluster for a cell cycle in the CgA addition group. The group additioned of CgA increased cell growth factor, MAPK and Smad gene group. We injected low-concentrated CgA into periodontal ligament, and we observed course, but the tissue changes was not found.
