A synthetic peptide fragment of thymosin beta-4, researched for wound healing and tissue repair.
Thymosin β4 (Tβ4) is expressed in developing tissue, where it stimulates cell differentiation and migration. Further, Tβ4 is expressed during molar development in mice, but the expression and function of Tβ4 in odontoblasts during mammalian tooth dev…
Thymosin beta-4 (Tβ4), actin-sequestering protein, plays important roles in many cellular functions including cancer cell migrations. Glycogen synthase kinase (GSK) in Wnt signaling pathway is a key molecule to control intercellular interaction. Here…
Melanoma is a malignancy characterized by high invasive/metastatic potential, with no efficient therapy after metastasis. Understanding the molecular mechanisms underlying the invasive/metastatic tendency is therefore important. Our genome-wide gene…
OBJECT: Thymosin β4 (Tβ4) is a regenerative multifunctional peptide. The aim of this study was to test the hypothesis that Tβ4 treatment initiated 6 hours postinjury reduces brain damage and improves functional recovery in rats subjected to traumatic…
Vascularization is critical for the survival of engineered tissues in vitro and in vivo. In vivo, angiogenesis involves endothelial cell proliferation and sprouting followed by connection of extended cellular processes and subsequent lumen propagatio…
Trichinella spiralis (T. spiralis) infection in muscle is characterized by the vascular network for the nurse cell-larva complex. We showed in a previous report that thymosin β4 was up-regulated during nurse cell formation by T. spiralis. As thymosin…
Antibodies against thymosin β4 are available from various sources and have been used in immunohistochemistry, ELISA, and Western blot analyses. None of these antibodies have been fully characterized for specificity and influence of fixation technique…
Clinical interventions leading to improved survival in patients with acute myocardial infarction have, paradoxically, increased the need for cardiac regenerative strategies as more people are living with heart failure. Over the last 10-15 years there…
OBJECTIVE: Thymosin β 4 (Tβ(4)) is a ubiquitous peptide that plays pivotal roles in the cytoskeletal system and in cell differentiation during embryogenesis. Recently, a role for Tβ(4) has been proposed in experimental and human carcinogenesis. This…
OBJECT: To evaluate the efficacy of thymosin beta 4 (Tβ(4)) on hyperglycemia and insulin sensitivity in a mouse model of type 2 diabetes mellitus (T2DM). METHODS: KK mice were divided into the following groups: KK control group, with saline treatment…
The mammalian heart loses its regenerative capacity during early postnatal stages; consequently, individuals surviving myocardial infarction are at risk of heart failure due to excessive fibrosis and maladaptive remodeling. There is an urgent need, t…
Finding insights into how viruses hijack metabolic processes and biomarkers for viral diseases often require hypotheses about target compounds and/or labelling techniques. Here we present a method based on laser ablation electrospray ionization mass…
RATIONALE: Thymosin beta 4 (Tβ4) is a 43-amino acid factor encoded by an X-linked gene. Recent studies have suggested that Tβ4 is a key factor in cardiac development, growth, disease, epicardial integrity, and blood vessel formation. Cardiac-specific…
In this review, we identify potential interaction partners of the β-thymosin family. The proteins of this family are highly conserved peptides in mammals and yet only one intracellular (G-actin) and one cell-surface protein (β subunit of F(1) -F(0) A…
Thymosin β4 (Tβ4) is a highly conserved G-actin binding polypeptide with multiple intra- and extracellular functions. While stem-cell activation as well as promotion of cell survival and migration by Tβ4 have been investigated in various in vitro and…
A sustained release formulation for the therapeutic peptide thymosin β4 (Tβ4) that can be localized to the heart and reduce the concentration and frequency of dose is being explored as a means to improve its delivery in humans. This review contains c…
INTRODUCTION: Thymosin β(4), a low molecular weight, naturally-occurring peptide plays a vital role in the repair and regeneration of injured cells and tissues. After injury, thymosin β(4), is released by platelets, macrophages and many other cell ty…
Trichinella spiralis (T. spiralis) has been reported to up-regulate the expression of the angiogenic molecule vascular endothelial cell growth factor (VEGF) during nurse cell formation. In order to analyze the induction of angiogenesis by T. spiralis…
OBJECTIVES: Thymosin beta4 (Tβ4) has been shown to have an important role in healing of damaged tissues and promoting cardiomyocyte survival in acute coronary syndromes. We evaluated endogenous Tβ4 levels in patients presenting with ST-elevation acut…
Thymosins are a family of highly conserved small peptides originally isolated from calf thymus. One representative member of the family is thymosin-β₄ (Tβ₄), a major G-actin-sequestering peptide present in many tissues. In the last decade, various st…
