A synthetic peptide fragment of thymosin beta-4, researched for wound healing and tissue repair.
Four trityl-type (i.e. non-substituted trityl-, o-Cl-trityl-, o-F-trityl- and p-CN-trityl-) amidomethyl polystyrene resins were evaluated comparatively, in terms of the stability of the trityl-ester bond in slightly acidic dichloromethane solutions,…
Osteoarthritis (OA) develops as a consequence of articular cartilage degeneration possibly initiated by excessive or abnormal loading of the joint, and potentially mediated through a proteinase/proteinase inhibitor imbalance. We have shown previously…
Thymosin beta(4) (Tbeta(4)), a highly conserved peptide with immunomodulatory properties, is the major actin-sequestering peptide in mammalian cells. Recent studies have established that Tbeta(4) can accelerate wound healing in full thickness skin wo…
Degradation of the myometrium contributes to the development of adenomyosis and disruption of the actin cytoskeleton occurs in the myometrium adjacent to the invasive endometrium. A subtractive cDNA library that contained genes up-regulated in the ut…
The intraepithelial lymphocyte (IEL) network of T-cell receptor gammadelta+ (Vgamma5+) dendritic epidermal T cells (DETC) in murine skin down-regulates cutaneous inflammation, although the mechanism is unknown. Thymosin-beta4 (Tbeta4), identified by…
Thymosin beta 4 is a small, 5-kDa protein with a diverse range of activities, including its function as an actin monomer sequestering protein, an antiinflammatory agent, and an inhibitor of bone marrow stem cell proliferation. Only the effects of thy…
BACKGROUND: Expression of the small peptide thymosin beta4 is associated with angiogenesis induction, accelerated wound healing, and the metastatic potential of tumor cells. However, little is known about the mechanism(s) by which thymosin beta4 prom…
Mechanical loading is paramount in regulating both the anabolic and catabolic activities of articular cartilage chondrocytes, essential for the matrix to retain its functional integrity. We have identified thymosin beta(4) as a putative mechanically…
The beta-thymosins are a highly conserved family of small polar peptides known to bind monomeric actin and inhibit its polymerization. The beta-thymosins show a high degree of sequence conservation among all vertebrate classes and they have been also…
UNLABELLED: In this study, the roles of hematopoietic inhibitors elaborated by bone marrow endothelial cells in the proliferation and differentiation of hematopoietic progenitors were investigated. Murine bone marrow endothelial cell conditioned medi…
Platelets share structural and functional similarities with granulocytes known to participate in antimicrobial host defense. To evaluate the potential antimicrobial activities of platelet proteins, normal human platelets were stimulated with human th…
BACKGROUND AND AIMS OF THE STUDY: Previous research has demonstrated that tenascin-C, an extracellular matrix protein involved in bone development and mineralization, was specifically present in calcified aortic valves, always in association with mat…
PURPOSE: In this study the effects of thymosin beta4 (Tbeta4) on migration and production of laminin-5 in the human conjunctival cell line HC0597 was analyzed. METHODS: Boyden chamber assays assessed the ability of Tbeta4 to stimulate in vitro cell m…
To identify genes that are involved in breast cancer, suppression subtractive hybridization (SSH) was utilized to construct a breast cancer subtracted library. Differential screening of the library isolated 28 genes which by Northern analysis were hi…
Hepatocyte growth factor (HGF) is a mesenchymal-derived cytokine. It exerts in vitro a motogenic effect on various target cells, which is displayed either by cell scattering, locomotion, and migration during the wound repair process of cultured cells…
The Listeria model system has been essential for the identification and characterization of key regulators of the actin cytoskeleton such as the Arp2/3 complex and Ena/vasodilator-stimulated phosphoprotein (VASP) proteins. Although the role of Ena/VA…
The cDNA thymosin beta(4) was synthesized by combining of chemical and enzymatic methods. First, two complement fragments of thymosin beta(4) cDNA were synthesized by DNA synthesizer, and then denatured, annealed and extended by DNA polymerase. This…
PURPOSE: Elevated expression of the beta-thymosin isotypes T beta(4), T beta(10), and T(15) appears to be involved in the manifestation of a malignant phenotype of human tumor cells, including those of mammary carcinomas. This has evoked an interest…
The beta-thymosins constitute a family of highly conserved and extremely water-soluble 5 kDa polypeptides. Thymosin beta4 is the most abundant member; it is expressed in most cell types and is regarded as the main intracellular G-actin sequestering p…
