An alternatively spliced cyclin D1 isoform, cyclin D1b, is a nuclear oncogene.
Glycogen synthase kinase-3beta-dependent phosphorylation of cyclin D1 at a conserved COOH-terminal residue, Thr-286, promotes CRM1-dependent cyclin D1 nuclear export at the G(1)-S boundary. Mutations that perturb the phosphorylation of cyclin D1 at Thr-286 contribute to cell transformation, although to date, no such mutations have been found in human cancers. Cyclin D1 (CCND1) undergoes alterna...
متن کاملCyclin D1 induction of cellular migration requires p27(KIP1).
The cyclin D1 gene is amplified and overexpressed in human breast cancer, functioning as a collaborative oncogene. As the regulatory subunit of a holoenzyme phosphorylating Rb, cyclin D1 promotes cell cycle progression and a noncatalytic function has been described to sequester the cyclin-dependent kinase inhibitor protein p27. Cyclin D1 overexpression correlates with tumor metastasis and cycli...
متن کاملAlternate cyclin D1 mRNA splicing modulates P27<sup>KlP1</sup> binding and cell migration
Cyclin D1 is an important cell cycle regulator but in cancer its overexpression also increases cellular migration mediated by p27 stabilization and RhoA inhibition. Recently, a common polymorphism at the exon 4-intron 4 boundary of the human cyclin D1 gene within a splice donor region was associated with an altered risk of developing cancer. Altered RNA splicing caused by this polymorphism give...
متن کاملCyclin D1 Expression in Patients with Laryngeal Squamous Cell Carcinoma
Background & Objective: Laryngeal squamous cell carcinoma (LSCC) is considered to be one of the most common cancers of the head and neck, accounting for roughly 90% of all malignant tumors of the larynx. To have a timely diagnosis for a better and practical therapy, molecular markers have to be investigated. The aim of this study was to determine the expression of Cyclin D1 (CD...
متن کاملPhosphorylation-dependent regulation of cyclin D1 nuclear export and cyclin D1-dependent cellular transformation.
GSK-3beta-dependent phosphorylation of cyclin D1 at Thr-286 promotes the nuclear-to-cytoplasmic redistribution of cyclin D1 during S phase of the cell cycle, but how phosphorylation regulates redistribution has not been resolved. For example, phosphorylation of nuclear cyclin D1 could increase its rate of nuclear export relative to nuclear import; alternatively, phosphorylation of cytoplasmic c...
