Cyclin D1 overexpression is observed mainly in nonfunctioning and aggressive pituitary tumors and is not a frequent event in corticotropinomas (Jordan et al., 2000). The cyclin D/CDK4/6 action is inhibited by the INK4 family of CDK inhibitors (p16, p18, and p19). p16/INK4 is encoded by the cyclin-dependent kinase inhibitor 2A (CDKN2A) gene.

Also substrate for SMAD3, phosphorylating SMAD3 in a cell-cycle-dependent manner and repressing its transcriptional activity. Component of the ternary complex, cyclin D2/CDK4/CDKN1B, Cyclin D turnover is regulated by ubiquitination and proteasomal degradation which are positively regulated by cyclin D phosphorylation on threonine-286 (Diehl et al., 1997). After the Cyclin D serves the role of mediating reactions by Cdk4 and Cdk6, it is shuttled to the cytoplasm and degraded in a ubiquitin-dependent manner. Three types of D-cyclins have been identified that show tissue-specific patterns of expression.1 Whereas cyclin D1 is known to be expressed mainly by epithelial cells or in some mesenchymal cells,2 cyclins D2 and D3 are expressed by myelomonocytic and lymphoid cells.3,4 An overexpression of cyclin D1 can be induced either by amplification of the chromosomal region of the cyclin D1 gene at Cyclin D/CDK4/6 complexes, together with cyclin E/CDK2, cause phosphorylation of the family of retinoblastoma proteins (pRb, p107, and p130) in the G1 phase of the cell cycle, resulting in abrogation of their growth inhibitory activity.

Cyclin D has been shown in many cancer types to be misregulated. Well established for their oncogenic properties, the cyclins, and the cyclin-dependent kinases (CDK's) they activate, have been the focus of major research and development efforts over the past decade.

Cyklin D ÖVERORDNAT BEGREPP. 2017-11-16 · Abundance of PD-L1, the ligand of the anti-cancer immunotherapy target PD-1, is negatively regulated by poly-ubiquitination via the cyclin D–CDK4/cullin 3–SPOP axis and PD-1 blockade treatment A cyclin subtype that is specific for CYCLIN-DEPENDENT KINASE 4 and CYCLIN-DEPENDENT KINASE 6. Unlike most cyclins, cyclin D expression is not cyclical, but rather it is expressed in response to proliferative signals. Cyclin D may therefore play a role in cellular responses to mitogenic signals.
