Two monoclonal antibodies against the receptor for platelet-derived growth factor (PDGF) were obtained by immunizing mice with pure PDGF receptor preparations derived from porcine uterus. The antibodies, denoted PDGFR-B1 and PDGFR-B2, both bound to the external domain of the receptor, as demonstrated by indirect immunofluorescence and binding of 125I-labeled antibodies to intact human fibroblas...
Platelet-derived growth factor (PDGF)-D is a PDGF receptor β (PDGFRβ)-specific ligand implicated in a number of pathological conditions, such as cardiovascular disease and cancer, but its biological function remains incompletely understood. In this study, we demonstrate that PDGF-D binds directly to neuropilin 1 (NRP1), in a manner that requires the PDGF-D C-terminal Arg residue. Stimulation wi...
BDNF (Brain derived neurotrophic factor) is a secretion protein and a member of the neurotrophin family of growth factors. Structural and functional characterization of BDNF Varanus komodoensis is of interest while its structure remains unknown. Thus, a homology molecular model of BDNF was constructed for gleaning possible structural insights. The model was compared with the structure of the ho...
سلول های بنیادی پالپ دندان شیری (shed) به عنوان یک جمعیت نو از سلول های بنیادی شناخته شده است که قادرند به انواعی از سلول ها شامل سلول های عصبی تبدیل شوند. سلول های بنیادی پالپ دندان از تاج عصبی منشا می-گیرند و ویژگی های نورونی شامل تولید فاکتورهای نوروتروفیک از قبیل ngf(nerve growth factor)،bdnf (brain derived neurotrophic factor) ، nt3 (neurotrophin 3) و nt4(neurotrophin 4) را دارا می باشند. ...
OBJECTIVE We used complementary deoxyribonucleic acid expression microarrays to assess the effects of radiotherapy on gene expression in glioblastoma multiforme. We hypothesized that postradiation recurrent tumors may demonstrate alterations in gene expression from the primary tumor specimen. METHODS Patients were diagnosed with glioblastoma multiforme at resection of the initial tumor, and t...
Background: Currently, a limited number of studies have been done on the vitrification of small ruminant oocytes, especially in sheep, where poor developmental rates are obtained following immature and mature oocyte vitrification. Poor ovine oocyte cryopreservation could attribute to the damage to enzymes which has role in metabolic pathways. Therefore, production of cytokines and growth factor...
