Three gene products, including Myc and the D- and E-type G1 cyclins, are rate limiting for G1 progression in mammalian fibroblasts. Quiescent mouse NIH 3T3 fibroblasts engineered to express a mutant colony-stimulating factor (CSF-1) receptor (CSF-1R 809F) fail to synthesize c-myc and cyclin D1 mRNAs upon CSF-1 stimulation and remain arrested in early G1 phase. Ectopic expression of c-myc or eit...
The metazoan cell cycle is driven by the timely and composite activities of cyclin-dependent kinases (CDKs). Among these, cyclin D- and cyclin E-dependent kinases phosphorylate the pRb family proteins during G(1) phase of the cell cycle and thereby advance cells beyond the restriction point. Increasing evidence suggests that cyclin D-dependent kinases might affect events other than Rb pathway-m...
The D-type cyclins are expressed during the progression from G0/G1 to S phase in the mammalian cell cycle. There is considerable evidence that they contribute to the development of specific cancers, both in humans and in mouse models. For example, cyclin D1 can be activated by chromosomal translocation, DNA amplification and retroviral integration. Cyclins D1, D2 and D3 preferentially associate...
Proliferating Cell Nuclear Antigen (PCNA) is a key nuclear protein of eukaryotic cells. It has been shown to form complexes with cyclin dependent kinases, cyclin dependent kinase inhibitors and the D-type cyclins which are involved in the cell cycle control. In Arabidopsis two genes coding for PCNA1 and PCNA2 proteins have been identified. In this study by analyzing Arabidopsis PCNA/CycD comple...
Walleye dermal sarcoma (WDS) and walleye epidermal hyperplasia (WEH) are skin diseases of walleye fish that appear and regress on a seasonal basis. We report here that the complex retroviruses etiologically associated with WDS (WDS virus [WDSV]) and WEH (WEH viruses 1 and 2 [WEHV1 and WEHV2, respectively]) encode D-type cyclin homologs. The retroviral cyclins (rv-cyclins) are distantly related ...
Plants contain more genes encoding core cell cycle regulators than other organisms but it is unclear whether these represent distinct functions. D-type cyclins (CYCD) play key roles in the G1-to-S-phase transition, and Arabidopsis (Arabidopsis thaliana) contains 10 CYCD genes in seven defined subgroups, six of which are conserved in rice (Oryza sativa). Here, we identify 22 CYCD genes in the po...
