Myocardial infarction (MI) is one of the leading causes of morbidity and mortality world-wide. Whether endogenous repair and regenerative ability could be augmented by drug administration is an important issue for generation of novel therapeutic appr…
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 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…
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…
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…
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…
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…
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…
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…
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…
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…
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…
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…
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…
OBJECTIVE: Cancer-associated fibroblasts (CAFs) are one of the hallmarks of the cancer microenvironment. Recent evidence has indicated that CAFs are more competent in enhancing cancer cell growth and migration than normal fibroblasts. However, the un…
OBJECTIVE: To asses thymosin β4 specificity as relevant to the diagnosis of Creutzfeldt-Jakob disease (CJD). DESIGN: A matrix-assisted laser desorption ionization time-of-flight mass spectrometry protein profiling analysis was applied to several neur…
The reprogramming of adult cells into pluripotent cells or directly into alternative adult cell types holds great promise for regenerative medicine. We reported previously that cardiac fibroblasts,which represent 50%of the cells in the mammalian hear…
Numerous studies have demonstrated the effects of Tβ4 on cell migration, proliferation, apoptosis and inflammation after exogenous treatment, but the mechanism by which Tβ4 functions is still unclear. Previously, we demonstrated that incubation of en…
