Independent and coordinate trafficking of single Drosophila germ plasm mRNAs.
Princeton, United States. In Nat Cell Biol, 06 May 2015
We find that the germ-cell-destined transcripts nanos, cyclin B and polar granule component travel within the oocyte as ribonucleoprotein particles containing single mRNA molecules but co-assemble into multi-copy heterogeneous granules selectively at the posterior of the oocyte.
A PP1-PP2A phosphatase relay controls mitotic progression.
Manchester, United Kingdom. In Nature, Feb 2015
The pathway is blocked in early mitosis because the Cdk1-cyclin B kinase (Cdk1 also known as Cdc2) inhibits PP1 activity, but declining cyclin B levels later in mitosis permit PP1 to auto-reactivate.
Apigenin, a dietary flavonoid, inhibits proliferation of human bladder cancer T-24 cells via blocking cell cycle progression and inducing apoptosis.
Tainan City, Taiwan. In Cancer Cell Int, Dec 2014
By performing flow cytometry and Western blotting, apigenin-mediated subG1 phase acculmulation was also associated with an increase in the phospho-p53, p53, p21, and p27 levels, and with a decrease in the Cyclin A, Cyclin B1, Cyclin E, CDK2, Cdc2, and Cdc25C levels, thereby blocking cell cycle progression.
Synergistic blockade of mitotic exit by two chemical inhibitors of the APC/C.
Boston, United States. In Nature, Nov 2014
An example is the anaphase-promoting complex/cyclosome (APC/C), a 13-subunit ubiquitin ligase that initiates the metaphase-anaphase transition and mitotic exit by targeting proteins such as securin and cyclin B1 for ubiquitin-dependent destruction by the proteasome.
Aurora-A: a potential DNA repair modulator.
Shanghai, China. In Tumour Biol, Apr 2014
Direct evidences from literatures suggest that Aurora-A inhibits pRb, p53, p21(waf1/cip1), and p27(cip/kip) but enhances Plk1, CDC25, CDK1, and cyclin B1 to repeal cell cycle checkpoints and to promote cell cycle progression.

The activation of the Cdk1 (cyclin-dependent kinase 1)-cyclin B complex to promote commitment to mitosis is controlled by the phosphorylation status of the Cdk1 catalytic subunit.
