Despite the numerous advances made in the prevention and treatment of cardiovascular diseases, there is a need for new strategies to repair and/or regenerate the myocardium after ischemia and infarction in order to prevent maladaptive remodeling and…
BACKGROUND: Filamentous actin (F-actin) forms polymers that contribute to the abnormal biophysical properties of sputum. Thymosin beta4 (Tbeta4) is the major monomeric actin-sequestering peptide in cells and can depolymerize F-actin. Tbeta4 could pot…
PURPOSE: Thymosin-beta4 (Tbeta4) is a small actin-sequestrating peptide that modulates inflammation and healing in different tissues. The aim of this study was to investigate the molecular and biochemical expression of Tbeta4 in the healthy conjuncti…
Proteins of the highly conserved PL-10 (Ded1P) subfamily of DEAD-box family, participate in a wide variety of biological functions. However, the entire spectrum of their functions in both vertebrates and invertebrates is still unknown. Here, we isola…
PL 14736 is a synthetic peptide, originally isolated from human gastric juice, that has anti-inflammatory and tissue-protective actions in experimental models of gastrointestinal inflammation. To investigate its possible benefit in poorly healing ski…
Formation of Ala-Glu-Asp-Gly peptide complex with duplex DNA [poly(dA-dT):poly(dA-dT)] at neutral pH and ambient temperature was studied experimentally. Peptide binding to duplex DNA was associated with hyperchromic effect indicating local separation…
A 12-year randomized clinical study of epithalamine (pineal gland peptide preparation) was carried out in elderly patients with coronary disease and accelerated aging of the cardiovascular system. Long-term treatment with epithalamine decreased the f…
Since conserved mammalian polypeptides are believed to exhibit enhanced immunogenicity in avian species, hens were immunized against the poorly immunogenic, highly conserved mammalian polypeptide prothymosin alpha (ProTalpha), i.e. against either non…
Talpha-1 tubulin promoter-driven EYFP expression is seen in murine neurons born as early as E9.5. Double labeling with markers for stem cells (Sox 1, Sox 2, nestin), glial progenitors (S100beta, NG2, Olig2), and neuronal progenitors (doublecortin, be…
Estrogen-receptor status provides a major biomarker in breast cancer classification and has an important impact on prognosis and treatment options. The aim of this study was to investigate peptide profiles of invasive breast cancer with positive (n=3…
Recursive relations are derived for nonlinear optical response functions of a two-level chromophore with stochastic frequency fluctuations described by a continuous-time random walk. Stationary ensembles are constructed and signatures of anomalous re…
OBJECTIVE: To evaluate the preventive and therapeutic effect of thymosin alpha(1) on lung infections in critical patients with tracheotomy. METHODS: Forty-two patients were randomly divided into treatment group and control group to receive daily subc…
BACKGROUND/AIMS: To observe the recurrence and prognosis of patients with hepatocellular carcinoma (HCC) coexisting with chronic hepatitis B infection with active virus replication after receiving antivirus therapy using lamivudine and thymosin alpha…
Dual reporter genes driven by either a ubiquitous cytomegalovirus (CMV) or a neuro-specific tubulin alpha1 promoter (Talpha1) were constructed. The new genes, CMV (pCMV-GL) or Talpha1 promoter-driven GFP-LacZ (pTalpha1-GL), robustly expressed the fus…
Combination therapy between two immunomodulators used for treatment of chronic hepatitis B was explored based on reported therapeutic efficacy of interferon-alpha, and thymosin-alpha1 as monotherapeutic agents to determine if combination therapy was…
Thymosin alpha1 (Talpha1), a 28-amino acid peptide, is a well-known immune system enhancer for the treatment of various diseases. In the present investigation, the effects of Talpha1 on the proliferation and apoptosis of human leukemia cell lines (HL…
BACKGROUND: More than one million individuals in Mexico are infected with hepatitis C virus (HCV), and 80% are at risk for developing a chronic infection that could lead to hepatic cirrhosis and other complications that impact quality of life and ins…
Thymosin alpha1 (Talpha1), a naturally occurring thymic peptide, primes dendritic cells (DCs) for antifungal T-helper type 1 resistance through Toll-like receptor 9 (TLR9) signaling. As TLR9 signaling also activates the immuno-suppressive pathway of…
AIM: To evaluate the potential therapeutic effect of liposomal gene delivery, genes encoding for human thymosin alpha1 (Talpha1) and interferon omega1 were injected via the tail vein into mice bearing a Hep-A-22 liver tumor. METHODS: The cDNA of huma…
AIM: To observe the efficiency and safety of thymosin-alpha1 treatment in patients with hepatitis B e antigen (HBeAg) and HBV DNA positive chronic hepatitis. METHODS: Sixty-two patients were randomly divided into groups A and B. The patients in group…
