| Research Abstract |
IL-1a increased phosphorylations of ERK, p38 MAPK, and HSP27, and expression of Ets-1 in human gingival fibroblasts. The inhibition of G1 cell cycle arrest in human gingival fibroblasts may result from an increase in phosphorylated Cdk2 and Rb proteins and decreased levels of p21 and p27 proteins by phenytoin. Because the phosphorylation of Ets-1 is controlled by cyclin, it is suggested that expressions of Ets-1 and ESE-3 by IL-1a is associated with gingival overgrowth.
