cyclin d1 breast cancer - Role of cyclin D1 in breast carcinoma


Breast carcinoma is the most frequent cancer among women with considerable invasive and metastatic behavior. CCND1, the oncogene encoding cyclin D1, is amplified in a substantial proportion of human cancers. Although cyclin D1 overexpression has been reported in up to 50% of human breast cancers Cited by: 10. Apr 02, 2007 · Cyclin D1b localization, stability and role in cancer development. A cyclin D1 splice variant (cyclin D1b) has been identified in various cell lines and tissues [60-63]. An alternative splicing event within exon 4, results in a 274 amino acid product lacking the C-terminal PEST domain and residue T286.Cited by: 571.

Cyclin D1 is a protein required for progression through the G1 phase of the cell cycle. During the G1 phase, it is synthesized rapidly and accumulates in the nucleus, and is degraded as the cell enters the S phase. Cyclin D1 is a regulatory subunit of cyclin-dependent kinases CDK4 and CDK6.Aliases: CCND1, BCL1, D11S287E, PRAD1, . The cyclin D1 gene, CCND1, is amplified in approximately 20% of mammary carcinomas, and the protein is over- expressed in approximately 50% of cases. This has led to intensive study to ascertain whether cyclin D1 is a biological marker in breast cancer; however, the Cited by: 276.

Cyclin D1 is one of the frequently overexpressed proteins and one of the commonly amplified genes in breast cancer. This article reviews the roles of cyclin D1 in cell-cycle regulation (normal and abnormal), mammary gland development and carcinogenesis and the relationship to oestrogen in breast tissues.Cited by: 213. Sep 28, 2011 · Cyclin D1 is a well-characterised cell cycle regulator with established oncogenic capabilities. Despite these properties, studies report contrasting links to tumour aggressiveness. It has previously been shown that silencing cyclin D1 increases the migratory capacity of MDA-MB-231 breast cancer cells with concomitant increase in 'inhibitor of differentiation 1' (ID1) gene expression.Cited by: 92.
