Zymographic analysis of secreted enzymes identified the main caseinolytic band at 54 kDa. Macelignan inhibited the expression of uPA protein and mRNA, as well uPA secretion, in KB cells exposed to P. gingivalis supernatant. Consistent with these findings, macelignan suppressed phosphorylation of p38 and c-Jun N terminal kinase (JNK) in P. gingivalis supernatant-induced KB cells. The levels of c-Fos and phosphorylated c-Jun, which together form AP-1, the transcription factor that is involved in uPA gene expression, were partially reduced by macelignan. Macelignan also blocked P. gingivalis supernatant-induced AP-1 activity in these cells. These results suggest that macelignan decreased P. gingivalis supernatant-induced uPA expression by blocking AP-1 activity, which may be mediated by inhibition of phosphorylation of p38 and JNK in KB cells. Macelignan may potently use for the modulation of periodontal inflammation. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Lihat Sejarah Pengadaan  Konversi Metadata   Kembali
