Molecular intermediates in T-cell activation pathways are crucial targets for the therapy and prevention of graft-versus-host disease (GVHD) following allogeneic hematopoietic cell transplantation (allo-HCT). We recently identified an essential role for cyclin-dependent kinase 5 (Cdk5) in T-cell activation and effector function, but the contribution of Cdk5 activity to the development of GVHD h...
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 real-time PCR. The subcellular translocation of CDK5 was monitored during gastric cancer ...
مقدمه: تنظیم افزایشی و کاهشی بیان ژن cdk5 به عنوان یک پروتئین کیناز، در سیستم عصبی راه اندازی مسیرهای مرگ یا بقا نورون ها را به همراه دارد. لذا با توجه به اثرات مزمن تمرین استقامتی بر رشد، جوانه زنی و عملکرد نورونی به ویژه در شرایط پاتولوژیکی تخریب عصبی، در پژوهش حاضر به بررسی تاثیر 6 هفته تمرین استقامتی بر میزان بیان ژن cdk5 در بخش حرکتی نخاع رت های نر ویستار با نوروپاتی دیابتی پرداختیم. روش ه...
Cyclin-dependent kinase 5 (Cdk5) is known to regulate prostate cancer metastasis. Our previous results indicated that Cdk5 activates androgen receptor (AR) and supports prostate cancer growth. We also found that STAT3 is a target of Cdk5 in promoting thyroid cancer cell growth, whereas STAT3 may play a role as a regulator to AR activation under cytokine control. In this study, we investigated t...
CDK5 is an important kinase in nervous system function, controlling neural development and postsynaptic signal integration. Here we show that CDK5 plays a major role in controlling neurotransmitter release. Inhibition of CDK5 activity, by either acute or genetic means, leads to profound potentiation of presynaptic function, including unmasking of previously "silent" synapses. Removal of CDK5 ac...
Two distinct protein cofactors, p35 and p39, independently activate Cyclin-dependent kinase 5 (Cdk5), which plays diverse roles in normal brain function and the pathogenesis of many neurological diseases. The initial discovery that loss of p35 impairs neuronal migration in the embryonic brain prompted intensive research exploring the function of p35-dependent Cdk5 activity. In contrast, p39 exp...
Cdk5 is a member of the cyclin-dependent kinase family, which is expressed predominantly in terminally differentiated neurons. Lower levels of Cdk5 are also found in a wide variety of cell types, including the lens. Although Cdk5 has been shown to play an important role in neuronal migration and neurite outgrowth, its function in non-neuronal cells is not known. Therefore, this study was undert...
Cyclin-dependent kinase 5(cdk5) is highly homologous to other members of the cdk family that are known to function in proliferating cells. Despite the structural similarity, cdk5-associated histone H1 kinase activity is only detectable in postmitotic neurons of the central nervous system (CNS). p35 is a neuronal-specific cdk5 regulator that activates cdk5 kinase activity upon association. The c...
PURPOSE To evaluate the nature of cyclin-dependent kinase 5 (CDK5) hyperactivity in pancreatic cancer progression. EXPERIMENTAL DESIGN We used genetic, biochemical, and molecular biology methods to investigate the nature and function of overexpression of CDK5 and its activators p35 and p39 during the progression of pancreatic cancer. RESULTS Amplification of the CDK5 gene or either of its m...
Two members of the CDK5 and ABL enzyme substrate (CABLES) family, CABLES1 CABLES2, share a highly homologous C-terminus. They interact associate with cyclin-dependent kinase 3 (CDK3), CDK5, c-ABL. mediates tumor suppression, regulates cell proliferation, prevents protein degradation. Although Cables2 is ubiquitously expressed in adult mouse tissues at RNA level, role CABLES2 vivo remains unknow...
