MG132, a proteasome inhibitor, induces apoptosis in tumor cells.
Chengdu, China. In Asia Pac J Clin Oncol, Mar 2013
There are many cancer-related molecules in which the protein levels present in cells are regulated by a proteasomal pathway; for example, tumor inhibitors (P53, E2A, c-Myc, c-Jun, c-Fos), transcription factors (transcription factor nuclear factor-kappa B, IκBα, HIFI, YYI, ICER), cell cycle proteins (cyclin A and B, P27, P21, IAP1/3), MG132 induces cell apoptosis through formation of reactive oxygen species or the upregulation and downregulation of these factors, which is ultimately dependent upon the activation of the caspase family of cysteine proteases.
Control of sleep by cyclin A and its regulator.
New York City, United States. In Science, 2012
We show that cyclin A (CycA) and regulator of cyclin A1, essential cell cycle factors, function in postmitotic neurons to promote sleep in Drosophila melanogaster.
How APC/C-Cdc20 changes its substrate specificity in mitosis.
Cambridge, United Kingdom. In Nat Cell Biol, 2011
Cdc20 requires APC3 and APC8 to bind and activate the APC/C when the spindle assembly checkpoint is satisfied, but only APC8 when active, and APC10 is crucial for the destruction of cyclin B1 and securin, but not cyclin A
