Abstract

We have reported that histone deacetylase (HDAC) inhibitors activate a member of the INK4 family, the p19INK4d gene, causing G1 phase arrest. We report here that HDAC inhibitor, Trichostatin A, activates another member of the INK4 family, the p18INK4c gene, through its promoter in Jurkat cells. Interestingly, the activation patterns of the p18INK4c gene were different from those of p19INK4d. Furthermore, mouse embryo fibroblasts lacking p18Ink4c or p18Ink4c/p19 Ink4d were resistant to the growth inhibitory effects of TSA as compared to their wild-type counterpart. Our findings suggest that p18 INK4c is involved in TSA-mediated cell growth inhibition and cooperates with p19INK4d. © 2004 Federation of European Biochemical Societies. Published by Elsevier B.V.
