This application claims priority under provisional patent application U.S. No. 61/288359, filed December 21, 2009, which is incorporated in this document by reference.
Matrix metalloproteinases (MMP) constitute a natural family of calcium-dependent and zinc-dependent endopeptidases, which are found in most mammals. It was suggested that increased expression and activation of MMP or the imbalance between MMP and MMP inhibitors play a role in the pathogenesis of diseases characterized by destruction of extracellular matrix or connective tissues.
The organic matrix is a major component of the periodontium (gums, cement, periodontal ligament and alveolar processes). Matrix metalloproteinases (MMP) are involved in periodontal reconstruction matrix. Destructive MMP destroy various components of the extracellular matrix in physiological and pathological conditions. Pathological over-production of destructive MMP leads to inadequate and excessive destruction of the matrix. Over-production of destructive MMP promotes resorption of bone tissue: first, due to the destruction of osteoid (not mineralized and noloop�organized bone matrix), and then the destruction of the Mature matrix, which may lead to clinical manifestations of periodontitis, including atrophy of the gingival margin, the formation of pockets, loss of fixation, tooth mobility and loss.
One of the main destructive MMP is MMP-13, which plays a role in the destruction of extracellular matrix. The expression level of MMP-13 correlated with clinical indicators of periodontitis. MMP-13 is detected in the diseased periodontal tissues and gingival fluid, but in a healthy oral mucosa of MMP-13 is missing. Uitto et al. American Journal of Pathophysiology, 152(6), 1489 (1998).
Matrix metalloproteinase-13 was identified as the enzyme responsible for bone resorption and cartilage destruction in rheumatoid arthritis and osteoarthritis. It is also known that the level of MMP-13 is elevated in gingival fluid in patients with chronic periodontitis. In addition, it is known that MMP-13 contributes to the destruction of both bone and connective tissue in patients with periodontal disease and periodontitis. Ilgenli, T. et al. Oral Diseases, 12, 573 (2006).
Currently for the treatment of diseases of the periodontium used antimicrobials, nonsteroidal anti-inflammatory drugs (NSPs), bisphosphonates and tetracyclines. These tools often fail to provide adequate relief of symptoms and, apparently, do not have a significant pliniana natural progression of the disease. In addition, most of these therapeutic modalities is associated with serious side effects. Therefore, there is a great need for safe and effective therapeutic treatment of such diseases.
Although there are many ways of treatment that are aimed at different aspects of periodontal disease, there remains a need to develop improved oral compositions containing active ingredients, which are aimed at destructive ISMS that contribute to the resorption of bone tissue and cause tissue destruction. There is a particularly urgent need to develop improved oral compositions targeting MMP-13, which contributes in bone resorption and destruction of the connective tissue.

Quantitative RT-PCR in real time
Cells UMR 06-01 were seeded into 12-well plates and cultured for 2-3 days in a culture medium for cell cultivation. After the merger, the cell culture medium was replaced with 1% fetal calf serum (5% fetal calf serum) for fasting cells during the night. Cells were preincubated with the active ingredient for 15 minutes and then incubated with PTH (10-8M) for 4 hours.
Total RNA from cells UMR 106-01, stimulated with or without PTH PTH, was isolated with TRIzol reagent. Total RNA (0.1 μg) back was transcribed into cDNA with a set of Superscript company Invitrogen according to the manufacturer's instructions. PCR was performed on cDNA using primers, the sequences of which are listed below. Samplefile performed adds 2.5 μl cDNA to a PCR mixture (22,5 ál) containing each primer (0.2 μm) and 12.5 µl of a mixture of Platinum SYBR Green qPCR SuperMix UDG (Invitrogen). The reaction was preincubated at 50°C for 2 minutes for the decontamination of dU-containing DNA by UDG, and then at 95°C for 2 minutes to inactivate UDG and Taq activation. The PCR program continued, performing 49 cycles of denaturation at 95°C for 15 seconds, annealing and elongation of the primers at 60°C for 30 seconds. Relative quantification of gene expression was performed using the 2-delta delta CT, with multiple changes in gene expression was determined relative to control samples. All samples were normalized to β-actin.
