Cyclin D1 is a putative proto-oncogene overexpressed in a wide variety of human neoplasms including mantle cell lymphomas (MCL). In addition, cyclin D1 positively regulates protein phosphorylation, mammary gland epithelial cell proliferation, and fat cell differentiation. In humans, the CCND1 gene encoding cyclin D1 is present on chromosome 11.

The hallmark of MCL is over expression of cyclin D1, however about 15% of all MCL cases do not display this over expression and are easily misdiagnosed.

Regulatory component of the cyclin D1-CDK4 (DC) complex that phosphorylates and inhibits members of the retinoblastoma (RB) protein family including RB1 and regulates the cell-cycle during G(1)/S transition. Cyclin D1 is more frequently dysregulated than cyclin D2 or D3 in human cancers, and as such, it has been more extensively characterized. Overexpression of cyclin D1 results in dysregulated CDK activity, rapid cell growth under conditions of restricted mitogenic signaling, bypass of key cellular checkpoints, and ultimately, neoplastic growth. Cyclin D1 is mostly known for the role played in the nucleus, as regulator of cell cycle progression. Cyclin D1 modulates the transition from G1 to S phase through its action as allosteric regulator of the cyclin-dependent kinase 4 (CDK) and CDK6. The active Cyclin D1/CDK4 complex translocates into 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.

Protein degradation is directed by polyubiquitylation and, thereafter, destruction via the 26S proteasome. Cyclin D1 degradation requires site-specific phosphorylation by GSK-3β at a con- between cyclin D1, Id1 and EMT in primary breast cancer, supporting our in vitro findings that low cyclin D1 expression can be linked to aggressive features in subgroups of breast cancer.

82. Cyclin D1 is a 36-kDa protein located on chromosome 11q13, a region commonly amplified in breast cancer (Fantl, Smith, Brookes, Dickson, & Peters, 1993).

Cyclin E expression rescued the mammary gland and retinal developmental abnormalities in only approximately 30% of cyclin D1 −/− mice, suggesting cyclin D1-specific function in these tissues. Intriguingly, p27 KIP1 (cyclin-dependent kinase inhibitor 1B) deficiency also rescued the mammary gland and retinal defects of cyclin D1 -deficient mice, suggesting that p27 KIP1 may be negatively

Cyclin D1 contributes to PDGF-induced gliomagenesis. Given the exciting discovery that the cdk inhibitor p21 facilitated the nuclear accumulation of cyclin D1–cdk4 complexes to drive the development of PDGF-induced glioma (), we wanted to probe this further by asking whether cyclin D1 and cdk4 were required for tumor formation.

2016-09-21 Cyclin D1 induced the secretion of miRNA governing the tumor immune response and oncogenic miRNAs. miR-21 and miR-93, which bind Toll-Like Receptor 8 to trigger a pro-metastatic inflammatory response, represented >85% of the cyclin D1-induced secreted miRNA transcripts. Cyclin D1 is the regulatory partner of the cyclin-dependent kinases (CDKs) CDK4 or CDK6. Once associated and activated, the cyclin D1/CDK complexes drive the cell cycle entry and G1 phase progression in response to extracellular signals.

Cyclin D1 is a 36-kDa protein located on chromosome 11q13, a region commonly amplified in breast cancer (Fantl, Smith, Brookes, Dickson, & Peters, 1993). Cyclin D1 functions in regulation of progression of the cell cycle through the G1 to S phase and in cellular metabolism (Fu, Wang, Li, Sakamaki, & Pestell, 2004). Definition / general Cyclin D1 is also known as BCL1, B Cell Lymphoma #1, CCND1 Coded by BCL1 / PRAD1 (parathyroid adenoma 1) gene on #11q13 Responsible for transition to S phase by phosphorylating the retinoblastoma gene product, which releases transcription factors to initiate DNA replication Cyclin D1 is more frequently dysregulated than cyclin D2 or D3 in human cancers, and as such, it has been more extensively characterized. Overexpression of cyclin D1 results in dysregulated CDK activity, rapid cell growth under conditions of restricted mitogenic signaling, bypass of key cellular checkpoints, and ultimately, neoplastic growth. Cyclin D1, a protein of 36 kD, is also known as PRAD1 or bcl-1. Maximum expression of cyclin D1 occurs at a critical point in mid to late G1 phase of the cell cycle. The cyclin D1 gene, located on 11q13 has been reported to be overexpressed in mantle cell lymphomas due to the chromosomal translocation t (11;18).
