A synthetic peptide fragment of thymosin beta-4, researched for wound healing and tissue repair.
This study presents the expression pattern and functions of thymosin beta 10 (Tbeta10), a Tbeta4 homologue during the development of mouse lower first molars. An in situ signal of Tbeta10 was detected on embryonic day 10.5 (E10.5)-E15.5 mainly in den…
The frog Xenopus can normally regenerate its limbs at early developmental stages but loses the ability during metamorphosis. This behavior provides a potential gain-of-function model for measures that can enhance limb regeneration. Here, we show that…
Thymosin β4 (Tβ4) is a low molecular weight peptide found in several mammalian tissues and is known mainly by its ability to bind cytoskeletal actin, influencing cell migration and differentiation, and promoting tissue repair. Considering the functio…
Ameloblastoma is regarded to be a benign odontogenic tumor, but it is destructive, locally invasive and presents a high rate of recurrence. Thymosin β4 (Tβ4) is closely associated with tooth germ development. Tβ4 also plays a role in malignant progre…
We previously demonstrated that thymosin β4 (Tβ4) regulates a variety of endothelial progenitor cell (EPC) functions, including cell migration, proliferation, survival and angiogenesis. However, the effect of Tβ4 on the senescence of circulating EPCs…
It has been proposed that thymosin beta 4 (TB4)-protein delivery stimulates differentiation of resident adult WT1-positive cardiac progenitor cells, but with very low efficiency. We determined whether gene therapy with human TB4 stimulates proliferat…
Thymosin β4 (Tβ4), a small acidic actin binding peptide, is overexpressed in a side population of cancer stem cells and CD133-positive colorectal cancer stem cells. In order to understand the relationship between Tβ4 and CD133, we studied the express…
Thymosin beta-4 (Tβ4) is known to be ubiquitously involved in the actin monomer sequestering on the cytoskeleton. Our previous study showed specific temporal and special in situ expression pattern of Tβ4 mRNA in dental epithelial and mesenchymal cell…
Cardiac KATP channels link metabolism with electrical activity. They are implicated in arrhythmias, secretion of atrial natriuretic peptide and protection of the heart from hypertrophy and failure. These processes may involve mechanosensitivity. KATP…
BACKGROUND: Our aim was to explore the therapeutic effects of peripheral blood-derived endothelial progenitor cells (PB-EPC) in cardiac ischemia-reperfusion infarction models in rats and in in vitro culture systems. METHODS: Rat models of ischemia re…
Interferon regulatory factor 6 (IRF6) encodes a highly conserved helix-turn-helix DNA binding protein and is a member of the interferon regulatory family of DNA transcription factors. Mutations in IRF6 lead to isolated and syndromic forms of cleft li…
Amyotrophic lateral sclerosis (ALS) is a devastating, rapidly progressing disease of the central nervous system that is characterized by motor neuron degeneration in the brainstem and the spinal cord. Matrix-assisted laser desorption/ionization (MALD…
Inflammation and angiogenesis are inevitable in vivo responses to biomaterial implants. Continuous progress has been made in biomaterial design to improve tissue interactions with an implant by either reducing inflammation or promoting angiogenesis.…
While cardiovascular diseases remain the major worldwide cause of mortality and morbidity, there is an urgent need to tackle the clinical and economic burden of heart failure. Since the mammalian heart is unable to adequately regenerate beyond early…
Epicardial resident stem cells are known to differentiate into cardiomyocytes during cardiac development, amongst other cell types. Whether epicardium-derived progenitor cells (EPDCs) retain this plasticity in the adult heart has been the topic of he…
Clinicians regularly transplant omental pedicles to repair a wide variety of injured tissues, but the basic mechanism underlying this efficacious procedure is not understood. One possibility that has not been addressed is the ability of omentum to di…
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…
Thymosin beta 4 (Tβ4), a G-actin sequestering peptide, increases oligodendrogenesis and improves functional outcome in models of neurological injury. The molecular mechanisms of Tβ4 mediated oligodendrogenesis are unclear. The p38 mitogen-activated p…
A veterinary preparation known as TB-500 and containing a synthetic version of the naturally occurring peptide LKKTETQ has emerged. The peptide segment (17)LKKTETQ(23) is the active site within the protein thymosin β(4) responsible for actin binding,…
