Spatial signals link exit from mitosis to spindle position
eLife, 2016 In budding yeast, if the spindle becomes mispositioned, cells prevent exit from mitosis by inhibiting the mitotic exit network (MEN). The MEN is a signaling cascade that localizes to spindle pole bodies (SPBs) and activates the phosphatase Cdc14.

A hyperactive transcriptional state marks genome reactivation at the mitosis–G1 transition
bioRxiv, 2016 During mitosis, RNA polymerase II (Pol II) and many transcription factors dissociate from chromatin, and transcription ceases globally. Transcription is known to restart in bulk by telophase, but whether de novo transcription at the mitosis-G1 transition

Phosphorylation of survivin at threonine 34 inhibits its mitotic function and enhances its cytoprotective activity [PDF]
, 2009 Survivin is an essential chromosomal passenger protein required for mitotic progression. It is also an inhibitor of apoptosis and can prevent caspase-mediated cell death.

Mechanical Cues Regulate Cargo Sorting and Export at the Golgi
Advanced Science, EarlyView.A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

Addressing a weakness of anticancer therapy with mitosis inhibitors: Mitotic slippage
Molecular & Cellular Oncology, 2017 Mitosis inhibitors, which include antimicrotubule drugs, are chemotherapy agents that induce the arrest and apoptosis of mitotic cells. Mitotic slippage, in which mitotically arrested cells exit mitosis, limits the effectiveness of mitosis inhibitors. We

Cell cycle regulation of a Xenopus Wee1-like kinase [PDF]
, 1995 Using a polymerase chain reaction-based strategy, we have isolated a gene encoding a Wee1-like kinase from Xenopus eggs. The recombinant Xenopus Wee1 protein efficiently phosphorylates Cdc2 exclusively on Tyr- 15 in a cyclin-dependent manner.

Advanced Science, EarlyView.This study presents a binary tumor‐microenvironment‐on‐a‐chip (T‐MOC) system incorporating multicellular tumor spheroids (MCTs) as an alternative preclinical platform to evaluate the efficacy of anticancer natural products. The T‐MOC model reproduces in vivo drug delivery barriers and physiological conditions, enabling morphological analysis to predict

Advanced Biomedical Research, 2012 Background: The cytological diagnoses of serous effusions are usually made by routine cytomorphology with certainty. However, overlapping cases sometimes exist between reactive mesothelial and adenocarcinoma cells.

The Long and Viscous Road: Uncovering Nuclear Diffusion Barriers in Closed Mitosis [PDF]
, 2014 During Saccharomyces cerevisiae closed mitosis, parental identity is sustained by the asymmetric segregation of ageing factors. Such asymmetry has been hypothesized to occur via diffusion barriers, constraining protein lateral exchange in cellular ...

Advanced Science, EarlyView.The quantitative proteomic and phosphoproteomic profiling reveals dynamic phosphorylation regulation of sperm morphogenesis. Kinase‐substrate phosphorylation network and phosphorylation module analysis, followed by in vivo knockdown and knockout analysis, identify TTBK2 and CSNK1G1 as key regulators of morphogenesis, including head, flagellar, and ...
