Effects of Prevotella intermedia lipopolysaccharide on the gene expression in periodontal ligment cells / 实用口腔医学杂志

ABSTRACT

Objective:To study the gene expression in periodontal ligament cells (PDLCs) stimulated by Prevotella intermedia(Pi) lipopolysaccharide (LPS). Methods:PDLCs of passage 7 were treated with Pi LPS at 100 ?g/ml for 24 h, then gene express of the cells was examined by a gene chip of 512 genes. Results: Genes of Z46973,M62810,AF109632,U45879,X81882,M10051,D14520 and L36529 were downregulated.Conclusion:Some genes in PDLCs can be downregulated by Pi LPS.
