Cyclin D1 expression in B-cell lymphomas

Experimental Hematology, 2010
Cyclin D1, an important component of cell cycle machinery and a protein with known oncogenic potential, is downregulated in normal mature B lymphocytes. Its expression detected in a number of malignancies, including B-cell lymphomas, may be important for oncogenesis.In our work, we determined the level of cyclin D1 expression in various B-cell ...

Cyclin D1 Inhibits Mitochondrial Activity in B Cells

Cancer Research, 2011
Abstract Cyclin D1 is a cell cycle regulatory protein that acts at the G1-S transition, following its binding to and activation by the cyclin-dependent kinases 4 or 6. Cyclin D1 is absent from the entire B-cell lineage but is present in a large percentage of 2 types of malignant B-cell hemopathy—mantle cell lymphoma and multiple ...

The expression of SOX11, cyclin D1, cyclin D2, and cyclin D3 in B-cell lymphocytic proliferative diseases

Medical Oncology, 2011
SOX11 is mainly correlated with embryo neurogenesis and remodeling of tissues. D cyclins (cyclin D1, cyclin D2, and cyclin D3) work in cell transformation. We assessed the expression of SOX11, cyclin D1, cyclin D2, and cyclin D3 mRNA in 152 patients with B-cell lymphocytic proliferative diseases (B-LPD) using qRT-PCR and we detected SOX11 protein using

Factors controlling cyclin B expression

Plant Molecular Biology, 2000
Cyclins control the transition between the phases of the eukaryotic cell cycle as regulatory subunits of the cyclin-dependent kinases (CDKs). Phase-specific activation of the CDK is in part regulated by phase-specific expression of their cyclin component. In most eukaryotic cells including higher plant, B-type cyclin genes are expressed specifically at

Homology Model of the CDK1/cyclin B Complex

Journal of Biomolecular Structure and Dynamics, 2005
We describe a refined homology model of a CDK1/cyclin B complex that was previously used for the structure-based optimization of the Paullone class of inhibitors. The preliminary model was formed from the homologous regions of the deposited CDK2/cyclin A crystal structure. Further refinement of the CDK1/cyclin B complex was accomplished using molecular

Cyclin D1 regulates p27Kip1 stability in B cells

Cellular Signalling, 2011
p27(Kip1) is a cyclin-dependent kinase inhibitor that plays a critical role in regulating G(1)/S transition, and whose activity is, in part, regulated through interactions with D-type cyclins. We have generated the BD1-9 cell line, a BaF3 pro-B cells derivative in which cyclin D1 can be induced rapidly and reversibly by ponasterone A.

Identification of a novel vertebrate cyclin: cyclin B3 shares properties with both A- and B-type cyclins.

The EMBO Journal, 1994
Cyclins play a key role in controlling progression through the cell cycle. They act as regulatory subunits of p34cdc2/CDC28 and related cyclin-dependent protein kinases (cdks). In vertebrates, cyclins B1 and B2 function during M phase, whereas cyclin A is required for S phase as well as the G2 to M phase transition. Here, we describe the identification

Cdk1/cyclin B‐mediated phosphorylation regulates SREBP1

The FASEB Journal, 2007
The sterol regulatory element‐binding protein (SREBP) family of transcription factors controls the biosynthesis of cholesterol and other lipids, and lipid synthesis is critical for cell growth and proliferation. We have found that the mature forms of SREBP1a and SREBP1c are hyperphosphorylated in mitotic cells, giving rise to a phosphoepitope ...
