Thymosin β4 is a major actin sequestering protein in cells and can interact with G-actin.
Cell lines | hCMEC/D3 cell line |
Preparation Method | Cells were treated with 200μM PrP (106-126) with or without Thymosin β4 and Thymosin β4 siRNA. Cell viability was determined by MTT assay and LDH assay. |
Reaction Conditions | 0.01, 0.05, 0.1, and 0.5μg/mL |
Applications | Pretreatment of hCMEC/D3 cells with various concentrations of Thymosin β4 on 200μM PrP (106-126)-treated cells resulted in significantly increased viability in a dose-dependent (0.1, 0.5 μg/ml) manner compared to cells incubated with 200μM PrP (106-126) alone. Analysis of LDH activity in the cell culture supernatants revealed that 0.1 and 0.5μg/ml Thymosin β4 significantly inhibited 200μM PrP (106-126)-induced cytotoxicity in hCMEC/D3 cells |
Animal models | CD1 adult nulliparous female mice, 2-5 months |
Preparation Method | Only 6 of 10 were pregnant. At 10:00 a.m. on day E14 and E17 of gestation mice were weighed and treated with an intraperitoneal injection of Thymosin β4. Three pregnant mice received treatment with Thymosin β4 and three mice were used as a control group. To keep the same conditions of stress, the mice of the control group underwent corresponding intraperitoneal injections of vehicle (PBS). On the day E19 of gestation, caesarean sections were performed. |
Dosage form | 6mg/kg, intraperitoneal injection |
Applications | Thymosin β4 is capable of accelerating the development of the entire fetus and fetal organs when administered to pregnant mice in the last week of gestation. Regarding the body length at birth, newborns of Thymosin β4-treated animals showed a length always higher than the neonates of non-treated mice. In multiple organs, including heart, kidney, lungs, gut, notochord and cerebral cortex, the degree of differentiation of stem/precursor cells was accelerated by the maternal administration of Thymosin β4, leading to the appearance of a more mature organ architecture |
| 产品描述 | Thymosin β4 is a major actin sequestering protein in cells and can interact with G-actin[1,2]. Thymosin β4 is found in many vertebrate tissues and cells and is especially concentrated in macrophages, fibroblasts, neutrophils, and platelets, which have large pools of G-actin[3]. The main physiological role of Thymosin β4 is the regulation of actin polymerization. Thymosin β4 is also involved in angiogenesis, cell survival, cell migration and fetal development[4]. Thymosin β4 plays a crucial role in the regulation of tight junction stability and acts in cytoskeleton rearrangement, which are closely related with BBB permeability[2]. Thymosin β4 is a novel regulator for primary cilia formation and it affects ciliogenesis by regulating the expression of NPHP3 in HeLa cervical cancer cells[5]. Thymosin β4 regulates HSC activation by influencing the activity of Smoothened and GLI2, suggesting Thymosin β4 as a novel therapeutic target in liver disease[6]. Synthetic Thymosin β4 peptide increases NK cell cytotoxicity mediated by intercellular adhesion molecule-1(ICAM-1) through the secretion of cytolytic granules to target cells, suggests that Thymosin β4 is a key activator of NK cell cytotoxicity[7]. Thymosin β4 enhanced wound healing in a rat full thickness wound model suggest that Thymosin β4 is a potent wound healing factor with multiple activities[1]. Thymosin β4 administration during gestation may act as a powerful fetal growth promoter, by accelerating the development of newborn organs and tissues[4].Recombinant Human Thymosin β4 significantly increased the survival rate of mice infected with MHV-A59 through inhibiting virus replication, balancing the host’s immune response, alleviating pathological damage, and promoting repair of the liver[8].
