14-3-3 proteins associate with cdc25 phosphatases.
The cdc25 phosphatases play key roles in cell cycle progression by activating cyclin-dependent kinases. Two members of the 14-3-3 protein family have been isolated in a yeast two-hybrid screen designed to identify proteins that interact with the human cdc25A and cdc25B phosphatases. Genes encoding the human homolog of the 14-3-3 epsilon protein and the previously described 14-3-3 beta protein h...
متن کاملA novel synthetic inhibitor of CDC25 phosphatases: BN82002.
CDC25 dual-specificity phosphatases are essential regulators that dephosphorylate and activate cyclin-dependent kinase/cyclin complexes at key transitions of the cell cycle. CDC25 activity is currently considered to be an interesting target for the development of new antiproliferative agents. Here we report the identification of a new CDC25 inhibitor and the characterization of its effects at t...
متن کاملcdc25 cell cycle-activating phosphatases and c-myc expression in human non-Hodgkin's lymphomas.
cdc25A, cdc25B, and cdc25C are a family of human phosphatases that activate the cyclin-dependent kinases at different points of the cell cycle. cdc25A and cdc25B have been shown to have oncogenic potential, and they have been identified as transcriptional targets of c-myc. To determine the role of cdc25 genes in the pathogenesis of human lymphomas and their possible correlation with c-myc dereg...
متن کاملDifferential expression of CDC25 phosphatases splice variants in human breast cancer cells.
BACKGROUND CDC25 phosphatases control cell cycle progression by activating cyclin dependent kinases. The three CDC25 isoforms encoding genes are submitted to alternative splicing events which generate at least two variants for CDC25A and five for both CDC25B and CDC25C. An over-expression of CDC25 was reported in several types of cancer, including breast cancer, and is often associated with a p...
متن کاملPharmacologic inhibition of CDC25 phosphatases impairs interphase microtubule dynamics and mitotic spindle assembly.
The CDC25 cell cycle regulators are promising targets for new pharmacologic approaches in cancer therapy. Inhibitory compounds such as BN82685 have proven to be effective in specifically targeting CDC25 in cultured cells and in inhibiting tumor cell growth. Here, we report that BN82685 impairs microtubule dynamic instability and alters microtubule organization and assembly at the centrosome in ...
