ProNGF and p75(NTR) are upregulated and induce cell death following status epilepticus (SE) in rats. However, less is known about the proneurotrophin response to SE in mice, a more genetically tractable species where mechanisms can be more readily dissected. We evaluated the temporal- and cell-specific induction of the proneurotrophins and their receptors, including p75(NTR), sortilin, and sorC...
The precursor of nerve growth factor (proNGF) has been described as a biologically active polypeptide able to induce apoptosis in neuronal cells, via the neurotrophin receptor p75(NTR) and the sortilin receptor. Herein, it is shown that proNGF is produced and secreted by breast cancer cells, stimulating their invasion. Using Western blotting and mass spectrometry, proNGF was detected in a panel...
Progranulin (PGRN) is a growth factor implicated in several neurodegenerative diseases, such as frontotemporal lobar degeneration. Despite its important role in the central nervous system (CNS), the mechanisms controlling PGRN expression in the CNS are largely unknown. Recent evidence, however, suggested that several stressors, such as hypoxia, acidosis, or oxidative stress, induce PGRN express...
BACKGROUND Neurotrophin receptors were initially identified in neural cells. They were recently detected in some cancers in association with invasiveness, but the function of these tyrosine kinase receptors was not previously investigated in colorectal cancer (CRC) cells. METHODS AND FINDINGS We report herein that human CRC cell lines synthesize the neural growth factor Brain-derived neurotro...
Several reports have shown that a sciatic nerve conditioned media (CM) causes neuronal-like differentiation in PC12 cells. This differentiation is featured by neurite outgrowth, which are exclusively dendrites, without axon or sodium current induction. In previous studies, our group reported that the CM supplemented with a generic inhibitor for tyrosine kinase receptors (k252a) enhanced the CM-...
Misfolding of tau proteins into prions and their propagation along neural circuits are thought to result in neurodegeneration causing Alzheimer's disease, progressive supranuclear palsy, chronic traumatic encephalopathy, and other tauopathies. Little is known about the molecular processes mediating tau prion replication and spreading in different brain regions. Using transgenic (Tg) mice with a...
به دلیل تشخیص دیر هنگام سرطان تخمدان و عدم شیوه های درمانی مؤثر، این بیماری از نظر تلفات در بین سرطان های زنان بیشترین مرگ و میر را دارد. نوروتنسین یک پپتید مغزی و گوارشی است که از طریق تعامل با رسپتورهای ویژه، عملکردهای مرکزی و محیطی زیادی را در مغز، لوله گوارش و سیستم قلبی عروقی انجام می دهد. این پپتید عصبی که به عنوان هورمون سیستم محیطی نیز به شمار می رود، سبب رشد بافت ارگان هایی همانند پانک...
G association studies have the potential to lead to identification of novel pathways and mechanisms for the pathogenesis of common complex diseases. Previous genome-wide association studies have identified a locus on 1p13 as a risk locus for dyslipidemia and myocardial infarction. However, the responsible mechanisms have remained elusive. Two recent reports implicate SORT1 as the causative gene...
Growth of axons and dendrites is a dynamic process that involves guidance molecules, adhesion proteins, and neurotrophic factors. Although neurite extension is stimulated by the neurotrophin nerve growth factor (NGF), we found that the precursor of NGF, proNGF, induced acute collapse of growth cones of cultured hippocampal neurons. This retraction was initiated by an interaction between the p75...
