Selective usage of D-Type cyclins by Ewing's tumors and rhabdomyosarcomas.
The genetic mechanisms that control proliferation of childhood musculoskeletal malignancies, notably Ewing's tumor (ET) and rhabdomyosarcoma (RMS), remain largely unknown. Most human cancers appear to overexpress at least one of the G1 cyclins (cyclins D1, D2, D3, E1, and E2) to bypass normal regulation of cell cycle G1 progression. We compared the gene expression profiles of 7 ET and 13 RMS pr...
متن کاملPlant D-type cyclins and the control of G1 progression.
The basic pattern of controls that operate during the G1 phase of the plant cell cycle shows much closer similarity to animals than to the yeasts and other fungi. The activity of D-type cyclin (CycD) kinases is induced in response to stimulatory signals, and these phosphorylate the plant homologue of the retinoblastoma tumour susceptibility (Rb) protein. It is likely that Rb phosphorylation res...
متن کاملComplexes of D-type cyclins with CDKs during maize germination
The importance of cell proliferation in plant growth and development has been well documented. The majority of studies on basic cell cycle mechanisms in plants have been at the level of gene expression and much less knowledge has accumulated in terms of protein interactions and activation. Two key proteins, cyclins and cyclin-dependent kinases (CDKs) are fundamental for cell cycle regulation an...
متن کاملThe D-type cyclins and their role in tumorigenesis.
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...
متن کاملRescue of defective mitogenic signaling by D-type cyclins.
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...
