Cyclin D1 Induces Chromosomal Instability
We developed mouse model systems to investigate the potential for cyclin D1 to induce CIN in vivo. In a mammary gland specific Tet-inducible model the acute expression profile regulated by cyclin D1 after 7 days was enriched in genes that rank highly with CIN. We also used a mammary gland targeted model (MMTV) to continuously express cyclin D1. The mice started to develop mammary gland tumors a...
متن کاملKinase-independent role of cyclin D1 in chromosomal instability and mammary tumorigenesis
Cyclin D1 is an important molecular driver of human breast cancer but better understanding of its oncogenic mechanisms is needed, especially to enhance efforts in targeted therapeutics. Currently, pharmaceutical initiatives to inhibit cyclin D1 are focused on the catalytic component since the transforming capacity is thought to reside in the cyclin D1/CDK activity. We initiated the following st...
متن کاملChIP sequencing of cyclin D1 reveals a transcriptional role in chromosomal instability in mice.
Chromosomal instability (CIN) in tumors is characterized by chromosomal abnormalities and an altered gene expression signature; however, the mechanism of CIN is poorly understood. CCND1 (which encodes cyclin D1) is overexpressed in human malignancies and has been shown to play a direct role in transcriptional regulation. Here, we used genome-wide ChIP sequencing and found that the DNA-bound for...
متن کاملAntisense Cyclin D1 Induces Apoptosis and Tumor Shrinkage
Cyclin D1 plays an essential regulatory role in the G1 phase of the cell cycle. The cyclin D1 gene is amplified in 20–50% of squamous cell carcinomas (SCCs), and the protein is overexpressed in up to 80% of SCCs. Our hypothesis was that gene transduction of antisense (AS) cyclin D1 in human SCCs in vivo would result in tumor reduction. A cyclin D1 cDNA was inserted into an E1/E3-deficient serot...
متن کاملCyclin D1 goes metabolic
Budding yeast is a preeminent model organism in studies of cellular aging pathways that are conserved in eukaryotes, including humans. There are two primary ways to query the lifespan of this organism.1 if one asks how many times a cell can divide, the answer will be its replicative lifespan (RLS). if, on the other hand, one asks how long a cell can stay alive without dividing, the answer will ...
