A synthetic peptide fragment of thymosin beta-4, researched for wound healing and tissue repair.
Chronic kidney disease represents a dramatic worldwide resource-consuming problem. This problem is of increasing importance even in preterm infants, since nephrogenesis may go on only for a few weeks (4 to 6 weeks) after birth. Recent literature focu…
Peripheral neuropathy is a chronic complication of diabetes mellitus. To investigated the efficacy and safety of the extended treatment of diabetic peripheral neuropathy with thymosin β4 (Tβ4), male diabetic mice (db/db) at the age of 24 weeks were t…
BACKGROUND: Random skin flaps can be used throughout the hands and fingers. Thymosin β4 can increase blood flow and reduce ischemia-reperfusion injury; the study was undertaken to investigate the effect of thymosin β4 on the survival of random skin f…
MALDI imaging mass spectrometry is a highly sensitive and selective tool used to visualize biomolecules in tissue. However, identification of detected proteins remains a difficult task. Indirect identification strategies have been limited by insuffic…
Signaling by small guanosine triphosphatases (GTPase), Rap1/Rac1, is one of the major pathways controlling cancer cell migration and tumor metastasis. Thymosin beta-4 (Tβ4), an actin-sequestering protein, has been shown to increase migration of cance…
Lamellipodia, the sheet-like protrusions of motile cells, consist of networks of actin filaments (F-actin) regulated by the ordered assembly from and disassembly into actin monomers (G-actin). Traditionally, G-actin is thought to exist as a homogeneo…
Due to its actin-sequestering properties, thymosin beta-4 (Tβ4) is considered to play a significant role in the cellular metabolism. Several physiological properties of Tβ4 have been reported;, however, many questions concerning its cellular function…
Although the various biological roles of thymosin β4 (Tβ4) have been studied widely, the effect of Tβ4 and Tβ4-expressing cells in the liver remains unclear. Therefore, we investigated the expression and function of Tβ4 in chronically damaged livers.…
PURPOSE: Standard therapies for severe dry eye are limited and fail to resolve the problem. The purpose of this study was to evaluate the safety and efficacy of Thymosin β4 eye drops (RGN-259) as a novel therapy for severe dry eye disease (including…
The therapeutic efficiency of recombinant thymosin β4 (rTβ4) synthesized by us was studied in vivo on spontaneous CBRB mouse model that is adequate to human chronic dermatitis. Three applications of the drug during a week significantly alleviated sym…
In previous studies by our group, we reported that thymosin beta 4 (Tb4) is closely associated with the initiation and development of the tooth germ, and can induce the expression of runt-related transcription factor 2 (RUNX2) during the development…
Hepatoblastoma (HB) is the most common malignant hepatic tumor in children and complete surgical resection offers the highest possibility for cure in this disease. Tumor metastasis is the principle obstacle to the development of efficient treatments…
Repairing defective cardiac cells is important towards improving heart function. Due to the frequency and severity of ischemic heart disease, management of patients featuring this type of cardiac failure receives significant interest. Previously we d…
OBJECTIVES: Thymosin β4 (Tβ4) is known to have pro-angogenic abilities in vitro and in vivo, and its cardioprotective effect is PI3/AKT-dependent. Tβ4-induced vessel formation requires transcriptional activation via the MRTF/SRF pathway. However, the…
KEY POINTS: Thymosin beta 4 (Tβ4 ) attenuates the vascular cellular toxicity induced by advanced glycation end products (AGEs) in human umbilical vein endothelial cells (HUVECs). Tβ4 reduces expression of both the receptor of AGEs (RAGE) and the fila…
Thymosin β4 (Tβ4) promotes CNS and peripheral nervous system (PNS) plasticity and neurovascular remodeling leading to neurological recovery in a range of neurological diseases. Treatment of neural injury and neurodegenerative disease 24 h or more pos…
OBJECTIVE: The actin polymerization regulator Thymosin β4 (Tβ4) has been shown to be involved in angiogenesis, wound healing, cell survival and anti-inflammatory responses. We have previously shown that Tβ4 is capable of recruiting pericytes, thus st…
Vascular endothelial growth factor (VEGF) is an important regulator of neovascularization. Hypoxia inducible nitric oxide (NO) enhanced the expression of VEGF and thymosin beta-4 (Tβ4), actin sequestering protein. Here, we investigated whether NO-med…
Thymosin beta 4 (Tβ4), which regulates vascular cell growth, can ameliorate some of the problems associated with diabetes. However, the precise signaling mechanisms by which Tβ4 protects against hyperglycemia-induced damage to endothelial cells have…
Peptide hormones represent an emerging class of potential doping agents. Detection of their misuse is difficult due to their short half-life in plasma and rapid elimination. Therefore, investigating their metabolism can improve detectability. Unfortu…
