A synthetic peptide fragment of thymosin beta-4, researched for wound healing and tissue repair.
Intratumoral hypoxia has been correlated with distant metastatic potential. Two hypoxia inducible factors (HIFs), HIF-1α and HIF-2α, are induced by hypoxia, and high expression of these proteins has been correlated to angiogenesis and distant metasta…
By an unknown mechanism, β-thymosins are extracellular modulators of angiogenesis, inflammation, wound healing, and development. We were interested in identifying β-thymosin interactors and determining their importance in β-thymosins signaling in hum…
We present use of a synthetic, injectable matrix metalloproteinase (MMP)-responsive, bioactive hydrogel as an in situ forming scaffold to deliver thymosin β4 (Tβ4), a pro-angiogenic and pro-survival factor, along with vascular cells derived from huma…
Thymosins are a family of highly conserved small peptides originally isolated from calf thymus. One representative member of the family is thymosin-β₄ (Tβ₄), a major G-actin-sequestering peptide present in many tissues. In the last decade, various st…
Thymosin β4 has been reported to play the key roles in tumor growth, metastasis, and angiogenesis. Although the importance of thymosin β4 in angiogenesis and metastasis is known, few studies to show the expression patterns of thymosin β4 in human tis…
Thymosin β4 (Tβ4) is a major intracellular G-actin-sequestering peptide. There is increasing evidence to support important extracellular functions of Tβ4 related to angiogenesis, wound healing and cardiovascular regeneration. We investigated the expr…
The pathogenesis of impaired healing within pressure ulcers remains poorly characterized and rarely examined. We describe the results of a pilot study that applies matrix-assisted laser desorption/ionization imaging mass spectrometry technology for d…
OBJECT: This study was designed to investigate the efficacy of delayed thymosin β(4) (Tβ(4)) treatment of traumatic brain injury (TBI) in rats. METHODS: Young adult male Wistar rats were divided into the following groups: 1) sham group (6 rats); 2) T…
Aspergillus fumigatus triggers inflammatory responses through Toll-like receptors (TLRs), particularly TLR2 and TLR4. In this study, we tested the hypothesis that lipopolysaccharide (LPS), a ligand of TLR4, can induce tolerance of A. fumigatus hyphae…
Thymosin beta-4 (Tβ4) is a member of beta-thymosins, a family of small peptides involved in polymerization of G-actin, and in many critical biological processes including apoptosis, cell migration, angiogenesis, and fibrosis. Previous studies in the…
RATIONALE: Thymosin beta-4 (Tβ4) is a ubiquitous protein with diverse functions relating to cell proliferation and differentiation that promotes wound healing and modulates inflammatory responses. The effecter molecules targeted by Tβ4 for cardiac pr…
A novel ionization device for controlling the charge states of peptides based on an inductive elecrospray ionization technique was developed. This ion source keeps the major capabilities of electrospray ionization (ESI) which is compatible with liqui…
AIM: Thymosin (Tβ4) may have various biological effects that are relevant to the pathogenesis of rheumatoid arthritis (RA). This study was performed to gain insight into the relevance of Tβ4 in the pathogenesis of inflammatory arthritis. METHOD: The…
Thymosin β4 (Tβ4) has been suggested to regulate multiple cell signal pathways and a variety of cellular functions such as cell migration, proliferation, survival, and angiogenesis. Here, we investigated the effect of Tβ4 on endothelial progenitor ce…
OBJECTIVES: Thymosin beta 4 (Tβ4) plays an essential role in cardiac vessel development and is currently being developed as a therapeutic agent for the treatment of coronary artery disease (CAD) in some experimental studies. Thus, we aimed to investi…
Venous ulcers are responsible for about 70% of the chronic ulcers of the lower limbs. Standard of care includes compression, dressings, debridement of devitalized tissue, and infection control. Thymosin beta 4 (Tbeta4), a synthetic copy of the natura…
Cornea absorbs most of daily ultraviolet (UV) light. An excess of UV damages results in not only keratopathy and cataract but also maculopathy. It has been reported that thymosin beta-4 (Tbeta4) promotes wound healing, decreases inflammatory response…
Thymosins beta 4 (Tβ4) is a member of the beta-thymosins family, a family of peptides playing essential roles in many cellular functions. Our recent studies suggested Tβ4 plays a key role in the development of human salivary glands and the…
The bHLH transcription factor Hand1 (Heart and neural crest-derived transcript-1) has a fundamental role in cardiovascular development; however, the molecular mechanisms have not been elucidated. In this paper we identify Thymosin β4 (Tβ4/Tmsb4x), wh…
β-Thymosins are small proteins that regulate the actin cytoskeleton and are involved in cell motility, differentiation, the induction of metalloproteinases, in anti-inflammatory processes and tumourigenesis. However, their roles in the ovary have not…
