| tissue inhibitor-of metalloproteinase-2 | <chemical> A member of the family of tissue inhibitor of metalloproteinases. It is a 21 kD nonglycosylated protein found in tissue fluid and is secreted as a complex with progelatinase a by human fibroblast and uncomplexed from alveolar macrophages. An overexpression of timp-2 has been shown to inhibit invasive and metastatic activity of tumour cells and decrease tumour growth in vivo. Pharmacological action: antineoplastic agent, protease inhibitors. (12 Dec 1998) |

| tissue inhibitor of-metalloproteinase-3 | <chemical> A member of the family of tissue inhibitor of metalloproteinases. It is a 21 kD, nonglycosylated protein. Timp-3 does not show a high degree of structural similarity unlike timp-1 and timp-2 which are structurally similar. However, it does possess a high degree of structural similarity with that of chicken timp-3 (chimp-3). Human timp-3 is of particular concern because of its potential role in cancer, arthritis, and eye diseases. Pharmacological action: antineoplastic agent, protease inhibitors. (12 Dec 1998) |
| tissue inhibitor of metalloproteinases | <chemical> A family of secreted proteins (timp-1, timp-2, and timp-3) that play a crucial role in regulating the activity of the secreted metalloproteinases (collagenases, stromelysins, gelatinases). Of the three characterised, only timp-1 and timp-2 appear to have related primary structures and inhibitory properties. They influence the activation of the prometalloproteinase and act to modulate proteolysis of extracellular matrix, notably during tissue remodeling and inflammatory processes. On certain cell types, they can exhibit growth factor-like activity, and they can inhibit the tumourigenic and metastatic phenotype in cancer cells. (pharmacol ther 1993;59:329-41) Pharmacological action: antineoplastic agent, protease inhibitors. (12 Dec 1998) |
| tissue inhibitors of metalloproteinase | <cell biology> Family of proteins of around 200 residues that can inhibit metalloproteinases, for example collagenase, by binding to them. (18 Nov 1997) |
| tissue lymph | True lymph, i.e., lymph derived chiefly from fluid in tissue spaces (in contrast to blood lymph). (05 Mar 2000) |
| tissue molding | The shaping of an impression material by the manipulation or action of the tissues adjacent to the borders of an impression. Synonym: muscle-trimming, tissue molding, tissue-trimming. (05 Mar 2000) |
| tissue perfusion | A term that describes blood flow into the tissues. Inadequate tissue perfusion is a clinical syndrome known as shock. (27 Sep 1997) |
| tissue plasminogen activator | <enzyme> Plasma serine protease, one of a closely related group of plasminogen activators. Contains an EGF like domain and multiple copies of the kringle domain. (18 Nov 1997) |
| tissue preservation | The process by which a tissue or aggregate of cells is kept alive outside of the organism from which it was derived (i.e., to keep from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism). (12 Dec 1998) |
| tissue procollagenase | <enzyme> Precursor of tissue collagenase; do not confuse with procollagenase, which is the precursor of clostridiopeptidase a Registry number: EC 3.4.24.- Synonym: promatrixmetalloproteinase-1, prommp-1, pro-matrix metalloproteinase-1 (26 Jun 1999) |
| tissue registration | In dentistry, the accurate registration of the shape of tissues under any condition by means of a suitable material, an impression. (05 Mar 2000) |
| tissue respiration | The interchange of gases between the blood and the tissues. Synonym: internal respiration. (05 Mar 2000) |
| tissue survival | The span of viability of a tissue or an organ. (12 Dec 1998) |
| tissue tension | A theoretical condition of equilibrium or balance between the tissues and cells whereby overaction of any part is restrained by the pull of the mass. (05 Mar 2000) |
| tissue therapy | Historically, tissue transplantation, especially of refrigerated tissue (after filatov). It was theorised that non-specific substances, capable of initiating restorative processes, formed in tissues when refrigerated. This therapy has been discredited and outlawed in western medicine. Cell therapy (after niehans) refers to implantation of tissue by injection. Originally this involved fresh cells but later frozen or lyophilised cells. This therapy has also been banned in most countries but its illicit use is apparently widespread. (12 Dec 1998) |
