Inflammation Biomarkers of Advanced Disease in Nongingival Tissues of Chronic Periodontitis Patients

Figure 3

Metalloproteinases (MMPs) expression in alveolar bone tissue of control subjects and periodontal disease (PD) patients. Total RNA extracted from bone biopsies of PD and control groups was subjected to qRT-PCR, SYBR green method. RNA expression of MMP-1 (a), MMP-2 (b), MMP-3 (c), and MMP-9 (d) is presented as the intensity of expression of the individual mRNAs, with normalization to β-actin, using the cycle threshold method. Data are the mean ± SEM results for patients with PD and control subjects tested individually. The results shown are from one experiment representative of three. .
