| tissue extracts | Preparations made from animal tissues or organs; they usually contain many components, any one of which may be pharmacologically or physiologically active; extracts may contain specific, but uncharacterised factors or proteins with specific actions. (12 Dec 1998) |
|---|---|
| tissue factor | <cell biology> Integral membrane glycoprotein of around 250 residues, that initiates blood clotting after binding factors VII or VIIa. (18 Nov 1997) |
| tissue fixation | The technique of using fixatives in the preparation of cytologic, histologic, or pathologic specimens for the purpose of maintaining the existing form and structure of all the constituent elements. (12 Dec 1998) |
| tissue fluid | The fluid in spaces between the tissue cells, constituting about 16% of the weight of the body; closely similar in composition to lymph. Synonym: tissue fluid. (05 Mar 2000) |
| tissue hormones | Hormones synthesised by cells other than those in the endocrine system. Compare: endocrine hormones. (05 Mar 2000) |
| tissue-inhibitor of metalloproteinase-1 | <chemical> A member of the family of tissue inhibitor of metalloproteinases. It is a n-glycosylated protein, molecular weight 28 kD, produced by a vast range of cell types and found in a variety of tissues and body fluids. It has been shown to suppress metastasis and inhibit tumour invasion in vitro. Pharmacological action: antineoplastic agent, protease inhibitors. (12 Dec 1998) |
| 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 polypeptide antigen | Serological tumour marker composed of a molecular complex of cytokeratins 8, 18, and 19. It is used in the diagnosis and staging of bronchogenic carcinoma. (12 Dec 1998) |
