| Research Abstract |
(l) Examination for the expression of uPA and MMPs stimulated by several cytokines using cultured cells.
The expression of uPA and MMPs was increased by the stimulation with TNFα using cultured cells derived from cartilaginous tissue of TMJ.
(2) Examination of transcriptional factor related to cytokines stimulation. Transcriptional factors, NF-kB and Sp1, were activated by TNFα stimulation at the cultured cells derived from cartilaginous tissue.
(3) Establishment of the condition for the gene transfer
We established the condition for the Decoy oligodeoxynucletides targeted to NF-kB and Sp1 using HVJ-liposome method, and decoy ODNs were routinely transferred to 1OO % of the cells.
(4) Inhibition of the expression of uPA and MMPs by Decoy ODNs transfection
The expression of the uPA and MMPs were inhibited by the transfection of Decoy ODNs to the cultured cells derived from cartilaginous tissue.
