MALDI-Mass Spectrometric Imaging Revealing Hypoxia-Driven Lipids and Proteins in a Breast Tumor Model.
Baltimore, United States. In Anal Chem, 16 Jul 2015
In this study, we identified hypoxia-regulated proteins active in several distinct pathways such as glucose metabolism, regulation of actin cytoskeleton, protein folding, translation/ribosome, splicesome, the PI3K-Akt signaling pathway, hemoglobin chaperone, protein processing in endoplasmic reticulum, detoxification of reactive oxygen species, aurora B signaling/apoptotic execution phase, the RAS signaling pathway, the FAS signaling pathway/caspase cascade in apoptosis, and telomere stress induced senescence.
Aurora B/C in Meiosis: Correct Me If I'm Right.
Paris, France. In Dev Cell, 08 Jul 2015
(2015) report that during meiosis I in mouse oocytes, the kinase Aurora B/C continuously destabilizes chromosome attachments to spindle microtubules, which potentially provides an explanation for the notably high error rate of chromosome segregation in mammalian oocytes.
The aurora kinases in cell cycle and leukemia.
Chicago, United States. In Oncogene, Mar 2015
The Aurora kinases, which include Aurora A (AURKA), Aurora B (AURKB) and Aurora C (AURKC), are serine/threonine kinases required for the control of mitosis (AURKA and AURKB) and meiosis (AURKC).
The dynamic protein Knl1 - a kinetochore rendezvous.
Québec, Canada. In J Cell Sci, Sep 2014
We present emerging roles of the protein interaction motifs present in Knl1, including the RVSF, SILK, MELT and KI motifs, and their role in the recruitment and regulation of the SAC proteins Bub1, BubR1, Bub3 and Aurora B. Finally, we explore how the regions of low structural complexity that characterize Knl1 are implicated in the cooperative interactions that mediate binding partner recognition and scaffolding activity by Knl1.
An up-date on newly discovered immunohistochemical biomarkers for the diagnosis of human testicular germ cell tumors.
Caserta, Italy. In Histol Histopathol, Aug 2014
For proper diagnosis of the different histological subgroups, immunohistochemistry is required using different molecular markers, such as Aurora B, GPR30, Nek2, HMGA1, HMGA2, and others, and they could represent useful novel molecular targets for antineoplastic strategies.
Feedback control of chromosome separation by a midzone Aurora B gradient.
Porto, Portugal. In Science, Aug 2014
A midzone-associated Aurora B gradient was found to monitor chromosome position along the division axis and to prevent premature chromosome decondensation by retaining Condensin I. PP1/PP2A phosphatases counteracted this gradient and promoted chromosome decondensation and NER.
