Angiogenesis contributes to various pathological conditions. Due to the resistance against existing antiangiogenic therapy, an urgent need exists to understand the molecular basis of vessel growth and to identify new targets for antiangiogenic therapy. Here we show that cyclin-dependent kinase 5 (Cdk5), an important modulator of neuronal processes, regulates endothelial cell migration and angio...
Background and Objective: Increased and decreased CDK5gene expression regulation, as a protein kinase, is associated with launching death or survival pathways in the nervous system. According to the chronic effects of endurance training on growth germination, neuronal function and improvement ofpathological conditions of neurodegenerative diseases, the aim of our study was to investigate the ef...
Purpose: As a cyclin-independent atypical CDK, the role of CDK5 in regulating cell proliferation in gastric cancer remains unknown. Experimental Design: Expression of CDK5 in gastric tumor and paired adjacent noncancerous tissues from 437 patients was measured by Western blotting, immunohistochemistry, and realtime PCR. The subcellular translocation of CDK5 was monitored during gastric cancer c...
Cdk5, a multifunctional kinase involved in a wide range of neuronal behavior, is regulated by its neuron-specific activators, p35 and p39. It is becoming clear that cdk5, like the MAP kinases, is a key player in signal transduction networks underlying neuronal cell survival, growth and differentiation. Our studies of cdk5 KO mice (-/-) have shown that they express a lethal phenotype with abnorm...
چکیده مقدمه: درد نوروپاتیک به صورت درد ناشی از آسیب یا بیماری سیستم عصبی حسی- پیکری تعریف می‌شود. نورون‌ها به کاهش و افزایش فعالیت به لحاظ بیوشمیایی سازگار می‌شوند که چنین تغییرات بیوشمیایی می‌تواند در حفظ و بقای نورون‌ها اثر گذار باشد، با توجه به نقش تنظیمی CDK5 در عملکرد و ساختار اعصاب هدف از انجام پژوهش حاضر بررسی تاثیر شش هفته فعالیت کاهش یافته به شکل درد نوروپاتیک بر بیان CDK5 در عصب سیاتی...
Several previous studies have demonstrated that CDK5 or p27 expression in gastric cancer are associated with overall survival. We have previously reported that tumor suppressive function of CDK5 is related to p27. The aim of this study was to investigate correlation between the clinicopathological parameters and overall survival with different CDK5/p27 expression statuses in 244 gastric cancer ...
CDK5 and its activator, p35, are expressed in mouse corneal epithelium and can be coimmunoprecipited from corneal epithelial cell lysates. Immunostaining shows CDK5 and p35 in all layers of the corneal epithelium, especially along the basal side of the basal cells. Stable transfection of corneal epithelial cells with CDK5, which increases CDK5 kinase activity by approximately 33%, also increase...
Neurotoxic insults deregulate Cdk5 activity, which leads to neuronal apoptosis and may contribute to neurodegeneration. The biological activity of Cdk5 has been ascribed to its phosphorylation of cytoplasmic substrates. However, its roles in the nucleus remain unknown. Here we investigate the mechanism by which Cdk5 promotes neuronal apoptosis. We have identified the prosurvival transcription f...
Cyclin-dependent kinase 5 (Cdk5) plays a key role in the development of the mammalian nervous system; it phosphorylates a number of targeted proteins involved in neuronal migration during development to synaptic activity in the mature nervous system. Its role in the initial stages of neuronal commitment and differentiation of neural stem cells (NSCs), however, is poorly understood. In this stud...
Cyclin-dependent kinase 5 (Cdk5) is a unique member of the Cdk family; its kinase activity requires association with its activator, p35 or p39. p35 is the strongest and best characterized activator. Previous studies showed that p35 is a neuron-specific protein that restricts Cdk5 activity in neurons. However, a high expression level of Cdk5 is found in astrocytes, which raises the possibility t...
