We previously showed that the -278 to +410 region of mouse thymosin beta4 (mT,beta4) gene supports high levels of reporter gene expression in NIH3T3 cells. This region contains part of the 5'-flanking sequences (-278 to -1), the intact first exon (+1…
Thymosin beta4 (Tbeta4), the actin-sequestering protein that regulates the polymerization and depolymerization of actins, is widely distributed in animal tissues. Expression of this gene in human cells is developmentally regulated and appears to play…
Protein expression profiles linked to sclerosis in the 5/6 nephrectomy (Nx) rat model of focal segmental glomerulosclerosis were investigated. Sections of control glomeruli from normal baseline Nx tissue and nonsclerotic and sclerotic glomeruli from…
Here, we review the biochemical and molecular properties of thymosin beta(4) (Tbeta(4)), the major actin-sequestering molecule in eukaryotic cells, and its key role in dermal- and corneal-wound healing. Tbeta(4) has several, novel, potential clinical…
We examined the detailed in situ expression pattern of thymosin beta 4 (Tbeta4) in the developing mouse mandibular first molar. Tbeta4 mRNA was expressed in the presumptive dental epithelium at embryonic day 10.5 (E10.5) and in the thickened dental e…
PURPOSE: To identify proteinases and growth factors abnormally expressed in human corneas of donors with diabetic retinopathy (DR), additional to previously described matrix metalloproteinase (MMP)-10 and -3 and insulin-like growth factor (IGF)-I. ME…
Thymosin beta4 is a major actin-sequestering molecule. Here, we report a prominent upregulation of thymosin beta4 in the hippocampus following entorhinal deafferentation. Northern blotting displayed a transient increase of thymosin beta4 mRNA in the…
Wiskott-Aldrich syndrome protein (WASP)-homology domain 2 (WH2) is a small and widespread actin-binding motif. In the WASP family, WH2 plays a role in filament nucleation by Arp2/3 complex. Here we describe the crystal structures of complexes of acti…
In the dystrophin-deficient mdx mice, an animal model of Duchenne muscular dystrophy (DMD), damaged skeletal muscles are efficiently regenerated and thus the animals thrive. The phenotypic differences between DMD patients and mdx mice suggest the exi…
The thermal rise threshold of an 810-nm semi-conductor diode laser on the root surface when used in root canals in vitro for laser assisted root canal treatment is investigated in this study. A total of 50 human single-rooted extracted teeth were inc…
The titer of thymic serum factor was measured in adult and old CBA females 15, 30, and 60 min, 24, 48, 72, and 96 h after injection of 3% suspension of sheep erythrocytes and changes of this parameter under the effect of epithalamin were studied in o…
Adenoviral vectors (AVV) are widely used as tools for exploring gene function in studies of the central autonomic control, but the cellular specificity of the promoters commonly used in these vectors has not been studied. We evaluated AVV with four "…
Hepatitis B virus (HBV) is one of the most prevalent viral pathogens of man with around 350 million chronically infected patients. It has been postulated that in persistently infected individuals the HBV-specific immune response is too weak to elimin…
Synthesized gene of human thymosin alpha 1 (Talpha1) was inserted into pET-28a, pET-9c, pThioHis B, pGEX-2T or pBV222 and then inductively expressed in strains of Escherichia coli. Among the five expression systems, the BL21/pET-28a system provides t…
A fusion thymosin alpha1-soluble B lymphocyte stimulator (TM alpha1-cBLyS) gene was generated to engineer a bifunctional lymphokine, which was then over-produced in Escherichia coli. The molecular weight of the expressed fusion protein was approximat…
The derivation of somatic cell types from pluripotent and self-renewing embryonic stem (ES) cells offers attractive prospects for basic research, compound development, and regenerative medicine. A key prerequisite for biomedical applications of ES ce…
BACKGROUND: This study was designed to compare the efficacy and safety of thymosin-alphal (T-alpha1) with that of interferon-alpha (IFN-alpha) in patients with chronic hepatitis B who were positive for hepatitis B virus (HBV) DNA and hepatitis B enve…
OBJECTIVE: To explore the inhibitory effect of combination of lamivudine with thymosin alpha1 (Talpha1) on the replication of duck hepatitis B virus (DHBV). METHODS: Peking ducks of 1 d old were challenged with DHBV-positive serum and used as a duck…
Precise determination of the peptide content in drug substance samples depends highly upon the particular peptide compound and methodology used. Four independent methods were evaluated and compared to determine which would produce the best experiment…
AIM: Interferon alpha2b (IFNalpha2b) and thymosin alpha1 (Talpha1) exhibit synergic effects in the treatment of hepatitis B and hepatitis C when used together. For developing a fusion protein drug, fusion proteins of IFNalpha2b and Talpha1 linked by…
