胶原酶、金属蛋白酶组织抑制因子-1和-2(TIMP-1和TIMP-2)在牙周炎中的表达被认为是由三个基因的表达调节的。采用逆转录-聚合酶链式反应(RT-PCR)检测牙周炎患者牙周组织中TIMP-1、TIMP-2和胶原酶基因表达的差异。这项技术允许从非常小的样本量中检测转录本。实验表明,疾病组TIMP-1和胶原酶转录本相对于β-肌动蛋白的水平显著高于健康对照组(TIMP-1分别为8.11+/-0.83和1.38+/-0.28%,胶原酶分别为0.50+/-0.10和0.0075+/-0.0024%)。TIMP-2在两组间差异无统计学意义(2.91+/-0.46比1.84+/-0.87%)。因此,宿主可能通过优先产生TIMP-1来应对胶原酶水平的增加,以对抗组织破坏。本研究中TIMP-1和TIMP-2基因表达的差异可能解释了TIMP-1和TIMP-2在体内的不同遗传调控。
Collagenolysis in periodontitis is thought to be modulated by the expression of three genes, collagenase, tissue inhibitors of metalloproteinases-1 and -2 (TIMP-1 and -2). We assessed the possible difference in TIMP-1, TIMP-2 and collagenase mRNA levels between gingival samples from patients with periodontitis and those from healthy subjects by reverse transcription-polymerase chain reaction (RT-PCR). This technique allows detection of transcripts from a very small sample quantity. The experiments showed that levels of TIMP-1 and collagenase transcripts relative to beta-actin are significantly higher in the diseased group than in healthy controls (8.11 +/- 0.83 versus 1.38 +/- 0.28% for TIMP-1 and 0.50 +/- 0.10 versus 0.0075 +/- 0.0024% for collagenase, respectively). The difference in TIMP-2 between the two groups (2.91 +/- 0.46 versus 1.84 +/- 0.87%) did not differ. Therefore, the host would have responded to the increase in collagenase level by preferentially producing TIMP-1 against tissue destruction. The differential gene expression of TIMP-1 and TIMP-2 in our study may account for a distinct genetic regulation of TIMP-1 and -2 in vivo.
