WebAug 12, 2009 · Abstract. D- and E-type cyclins mediate G1-S phase cell cycle progression through activation of specific cyclin-dependent kinases (cdk) that phosphorylate the retinoblastoma protein (pRb), thereby alleviating repression of E2F-DP transactivation of S-phase genes. Cyclin D1 is often overexpressed in a variety of cancers and is associated … WebCyclin E mRNA and protein expression were determined by RT-PCR and western blotting. Cell proliferation and clonality were detected using a CCK-8 test and soft agar colony formation assay. Cell cycle distribution, apoptosis and invasion of EC9706, Eca109 and KYSE30 cells were evaluated with flow cytometry and a transwell culture system.

Cyclin E - Wikipedia

Cyclin E is a member of the cyclin family. Cyclin E binds to G1 phase Cdk2, which is required for the transition from G1 to S phase of the cell cycle that determines initiation of DNA duplication. The Cyclin E/CDK2 complex phosphorylates p27 (an inhibitor of Cyclin D), tagging it for degradation, thus promoting … See more Like all cyclin family members, cyclin E forms a complex with cyclin-dependent kinase (CDK2). Cyclin E/CDK2 regulates multiple cellular processes by phosphorylating numerous downstream proteins. See more Over-expression of cyclin E correlates with tumorigenesis. It is involved in various types of cancers, including breast, colon, bladder, skin and lung cancer. DNA copy-number amplification of cyclin E1 is involved in brain cancer.
