Cyclin A1 Rabbit Pab Leader in Biomolecular Solutions for Life Science Cyclin A1 Rabbit pAb Catalog No.: A14529 Basic Information Background Catalog No. The protein encoded by this gene belongs to the highly conserved cyclin family, whose A14529 members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct Observed MW expression and degradation patterns which contribute to the temporal coordination of 52kDa each mitotic event. The cyclin encoded by this gene was shown to be expressed in testis and brain, as well as in several leukemic cell lines, and is thought to primarily function in Calculated MW the control of the germline meiotic cell cycle. This cyclin binds both CDK2 and CDC2 47kDa/52kDa kinases, which give two distinct kinase activities, one appearing in S phase, the other in G2, and thus regulate separate functions in cell cycle. This cyclin was found to bind to Category important cell cycle regulators, such as Rb family proteins, transcription factor E2F-1, and the p21 family proteins. Multiple transcript variants encoding different isoforms Primary antibody have been found for this gene.

The proto-oncogene MYC is strategies is required in the setting of relapsed and refractory disease, typified frequently dysregulated in the aggressive B-cell lymphomas, however, it has proven an elusive direct therapeutic target. MYC-dysregulated disease maintains a ‘transcriptionally-addicted’ state, whereby perturbation of A significant body of evidence is accumulating to suggest that RNA polymerase II activity may indirectly antagonise MYC activity. Furthermore, very recent studies implicate anti-apoptotic myeloid cell leukaemia 1 (MCL-1) as a critical survival determinant of MYC-driven lymphoma. This thesis utilises pharmacologic and genetic techniques in MYC-driven models of aggressive B-cell lymphoma to demonstrate that cyclin-dependent kinase 9 (CDK9) and MCL-1 are oncogenic dependencies of this subset of disease. The cyclin-dependent kinase inhibitor, dinaciclib, and more selective CDK9 inhibitors downregulation of MCL1 are used

In contrast, postmitotic multiciliated cells (MCCs) uncouple centriole assembly from cell cycle progression and produce hundreds of centrioles in the absence of DNA replication to serve as basal bodies for motile cilia. Although some cell cycle regulators have previously been implicated in motile ciliogenesis, how the cell cycle machinery is employed to amplify centrioles is unclear. We use transgenic mice and primary airway epithelial cell culture to show that Cdk2, the kinase responsible for the G1 to S phase transition, is also required in MCCs to initiate motile ciliogenesis. While Cdk2 is coupled with cyclins E and A2 during cell division, cyclin A1 is required during ciliogenesis, contributing to an *For correspondence: alternative regulatory landscape that facilitates centriole amplification without DNA replication.

However, the molecular mechanism(s) underlying their different tumor growth remains unknown. The aim of the current study was to evaluate and compare the gene expression profile of cell cycle regulators and cell growth-related transcription factors in CD, SCA, and non-functioning adenomas (NFA). Design and methods: Tumor tissue specimens resected from 43 pituitary tumors were studied: CD (nZ10), SCA (nZ11), and NFA (nZ22). The absolute transcript numbers of the following genes were quantified with real-time quantitative PCR assays: CDKN2A (or p16INK4a), cyclin family (A1, B1, D1, and E1), E2F1, RB1, BUB1, BUBR1, ETS1, and ETS2. Protein expressions of p16 and cyclin D1 were semi-quantitatively evaluated by immunohistochemical study. Results and conclusion: CDKN2A gene expression was about fourfold greater in CD than in SCA and NFA.

A specifically designed strategy was applied to oral squamous cell carcinomas (OSCC) in order to detect ectopic gene activations and develop a prognostic stratification test. METHODS: A dedicated original prognosis biomarker discovery approach was implemented using genome-wide transcriptomic data of OSCC, including training and validation cohorts. Abnormal expressions of silent genes were systematically detected, correlated with survival probabilities and evaluated as predictive biomarkers. The resulting stratification test was confirmed in an independent cohort using immunohistochemistry. RESULTS: A specific gene expression signature, including a combination of three genes, AREG, CCNA1 and DDX20, was found associated with high-risk OSCC in univariate and multivariate analyses. It was translated into an immunohistochemistry-based test, which successfully stratified patients of our own independent cohort. DISCUSSION: The exploration of the whole gene expression profile characterising

Academic Editor: Jonas Cicenas Received: 17 December 2014 / Accepted: 12 January 2015 / Published: 23 January 2015 Abstract: Cyclin-dependent kinases (CDK/Cyclins) form a family of heterodimeric kinases that play central roles in regulation of cell cycle progression, transcription and other major biological processes including neuronal differentiation and metabolism. Constitutive or deregulated hyperactivity of these kinases due to amplification, overexpression or mutation of cyclins or CDK, contributes to proliferation of cancer cells, and aberrant activity of these kinases has been reported in a wide variety of human cancers. These kinases therefore constitute biomarkers of proliferation and attractive pharmacological targets for development of anticancer therapeutics. The structural features of several of these kinases have been elucidated and their molecular mechanisms of regulation characterized in depth, providing clues for development of drugs and inhibitors to disrupt their function. However, like most other kinases, they constitute a challenging class of therapeutic targets due to their highly conserved structural features and ATP-binding pocket.
