Cerebral ischemia causes severe brain injury and results in selective neuronal death through programmed cell death mechanisms, including apoptosis and autophagy. Minimizing neuronal injury has been considered a hot topic among clinicians. The present…
Globular (G)-actin, the actin monomer, assembles into polarized filaments that form networks that can provide structural support, generate force and organize the cell. Many of these structures are highly dynamic and to maintain them, the cell relies…
Wide-lineH NMR measurements were extended and all results were reinterpreted in a new thermodynamics-based approach to study aqueous solutions of thymosin-β(Tβ), stabilin C-terminal domain (CTD) and their 1:1 complex. The energy distributions of the…
OBJECTIVE: The aim of the study was to determine whether serum thymosin beta4 (Tβ4) can be a useful noninvasive biomarker to differentiate between nonalcoholic steatohepatitis (NASH) and nonalcoholic fatty liver (NAFL). METHODS: The study included 24…
This study evaluated the clinical activity of RGN-259 (thymosin β4) in comparison with cyclosporine A (CsA), diquafosol (DQS), and lifitegrast (LFA) in a murine model of dry eye. The model was NOD.B10-H2mice in a 30-40% humidified environment togethe…
Cardiovascular diseases (CVDs) represent ∼31% of all global deaths, and hypertension alone accounts for ∼50% of these cases. Inflammation and subsequent fibrosis in heart, kidney and brain are associated with increased morbidity and mortality in CVD…
Thymosin β4 (Tβ4) is a multifunctional N-acetylated peptide with distinct activities important at various stages. Due to its potential multiple therapeutic uses in many fields, there is an increasing need of Tβ4 at lower costs than with the use of ch…
BACKGROUND: The present study aimed to clarify the effects of thymosin β4 (Tβ4) on CCl-induced hepatic fibrosis in mice and to further explore the underlying mechanisms. METHODS: Expression of Tβ4 in fibrotic liver tissues was assessed by a quantitat…
Endothelial progenitor cells (EPCs) are a promising cell source for tissue repair and regeneration, predominantly through angiogenesis promotion. Paracrine functions serve a pivotal role in EPC‑mediated angiogenesis, which may be impaired by various…
Translations of new therapeutic options for cardiovascular disease from animal studies into a clinical setting have been hampered, in part by an improper reflection of a relevant patient population in animal models. In this study, we investigated the…
OBJECTIVES: Thymosin beta 4 (Tβ4) has demonstrated neuroprotective potential in models of neurlogical injury. The neuroprotective potential of Tβ4 has been associated with increased miR-200a and miR-200b within the brain following stroke. Here we tes…
The transcription factor Islet-1 marks a progenitor cell population of the second heart field during cardiogenesis. In the adult heart Islet-1 expression is limited to the sinoatrial node, the ventricular outflow tract, and parasympathetic ganglia. T…
OBJECTIVE: To study the effects of exogenous thymosinβ4 (Tβ4) treatment in acetaminophen (APAP)-induced hepatotoxicity. METHODS: Liver injury was induced in mice by a single intraperitoneal injection of APAP (500 mg/kg). Exogenous Tβ4 was intraperito…
INTRODUCTION: There is an urgent need for new treatments for chronic kidney disease (CKD). Thymosin-β4 is a peptide that reduces inflammation and fibrosis and has the potential to restore endothelial and epithelial cell injury, biological processes i…
Thirty percent of global mortalities are caused by cardiovascular disease, and 54% of the aforementioned amount is instigated by ischemic heart disease that triggered myocardial infarction. Myocardial infarction is due to blood flow cessation in cert…
Thymosin β4 (Tβ4), a ubiquitous peptide, regulates several cellular processes that include cell morphology, wound healing, and inflammatory response. Administration of exogenous Tβ4 is protective in diabetic nephropathy and in a unilateral ureteral o…
INTRODUCTION: Formation of the vasculature is a complex process, defects in which can lead to embryonic lethality or disease in later life. Understanding mechanisms of vasculogenesis may facilitate the treatment of developmental defects and may be ex…
INTRODUCTION: Thymosin β4 (Tβ4) is a thymic hormone with multiple and different intracellular and extracellular activities affecting wound healing, inflammation, fibrosis and tissue regeneration. As the failure to resolve inflammation leads to uncont…
INTRODUCTION: Thymosin beta-4 (Tβ4) is an actin sequestering protein and is furthermore involved in diverse biological processes including cell proliferation, differentiation, wound healing, stem- or progenitor cell differentiation, and modulates inf…
Here, we demonstrated chimeric adeno-associated virus (chimeric AAV), AAV-DJ-mediated cardiovascular reprogramming strategy to generate new cardiomyocytes and limit collagen deposition in cardiac fibroblasts by inducing synergism of chimeric AAV-expr…
