BACKGROUND: Chondrosarcomas are malignant cartilage tumors that do not respond to traditional chemotherapy or radiation. The 5-year survival rate of histologic grade III chondrosarcoma is less than 30%. An animal model of chondrosarcoma has been esta…
Angiogenesis is induced by soluble factors such as vascular endothelial growth factor (VEGF) released from tumor cells in hypoxia. It enhances solid tumor growth and provides an ability to establish metastasis at peripheral sites by tumor cell migrat…
Cell migration plays an important role in many physiological and pathological processes, including tumor metastasis. Tumor cell migration is increased through the sequential induction of HIF-1α and VEGF under hypoxic conditions. Thymosin β-4 (Tβ4) is…
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…
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…
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…
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…
In experiments on mice of lines C57BL/6J and CBA/CaLac, the possibility of strengthening of analgesic effect of corvitin by the action of red polarized light (PL) on the acupoint (AP) E-36 was studied. The pain behavioral response (licking of the pai…
Urinary incontinence in animals poses a growing therapeutic problem. Satisfactory results in the treatment of incontinence are not reported despite the wide availability of pharmaceuticals addressing the problem. The growing number of side effects an…
BACKGROUND/AIMS: Supplementation of n-3 long-chain polyunsaturated fatty acids (LCPUFA) is considered as adjuvant therapy in acute pancreatitis. We investigated plasma fatty acid status in chronic pancreatitis (CP). METHODS: Patients with alcoholic C…
Neonatal hypophysectomy in chicken produces enlarged follicles of the thyroid gland, accumulation of colloids, impressed follicular epithelium, increased nucleus-cytoplasm ratio in thyrocytes, atrophied inter-follicular epithelium, depressed immunity…
Identification of the molecule(s) that globally induce a robust regenerative state in sensory neurons following peripheral nerve injury remains elusive. A potential candidate is brain-derived neurotrophic factor (BDNF), the sole neurotrophin upregula…
Dorsal root ganglia (DRG) are recognized as one of the organs which are damaged in peripheral sensory diabetic neuropathy. In an experimental animal model, the alteration of the mRNA expression level of neurotrophins, their receptors and neuronal cyt…
BACKGROUND: Dental trauma is common. One of the most severe injuries is when a permanent tooth is knocked completely out (avulsed) of the mouth. In most circumstances the tooth should be replanted as quickly as possible. There is uncertainty on how b…
OBJECTIVE: Glucocorticoids (GCs) are indicated for a number of conditions in obstetrics and perinatal medicine; however, the neurodevelopmental and long-term neurological consequences of early-life GC exposure are still largely unknown. Preclinical s…
PURPOSE: Thymosin alpha 1 (Talpha1) is an immunomodulatory polypeptide that enhances effector T-cell responses. In this large randomized study, we evaluated the efficacy and safety of combining Talpha1 with dacarbazine (DTIC) and interferon alfa (IFN…
Hybrid protein, cancer necrosis factor thymosin-alpha1 (CNF-T), when synthesizing in strain-producer of Escherichia coli SG200-50 with plasmid pThy315, was a part of "inclusion bodies" mostly in the form of a high-molecular complex with other protein…
Human thymosin alpha1 is an effective immune system enhancer for the treatment of cancer and viral diseases. Therefore the development of new methods for its synthesis is an urgent problem. In the present work, we propose an efficient scalable scheme…
Thymosin-alpha1 (Talpha1) is indicated for the treatment of certain viral infections, including hepatitis B and C, and cancers, such as melanoma. In this paper, the fusion genes encoding human serum albumin (HSA) and Talpha1 with (rHSA-L-Talpha1) and…
IMPORTANCE OF THE FIELD: Inflammatory diseases are characterized by severe immune imbalances, leading to excessive or inappropriate release of mediators, which, in turn, result in massive damage to organs and systems. Effective means to control inapp…
