CRC 1430
Welcome to the Collaborative Research Centre "Molecular Mechanisms of Cell State Transitions" (CRC 1430)
The DFG-funded CRC 1430 "Molecular Mechanisms of Cell State Transitions" explores fundamental molecular mechanisms that underlie the regulation of cell proliferation. Cell proliferation needs to be tightly controlled to ensure organismal development and tissue regeneration, while preventing neoplastic disorders. A key hallmark of this control is the establishment of distinct, biochemically or epigenetically defined cell states and the regulated transitions between these states.
These transitions govern cell cycle progression and underlie cancer cell plasticity and cancer therapy resistance. The research focus is on understanding the switch-like molecular trigger mechanisms of state transitions and develop means to modulate them, ultimately to identify novel therapeutic strategies. Specifically, to overcome current limitations, the CRC 1430 will develop and apply direct methodologies such as advanced biochemical reconstitution and novel approaches of acute chemical or optical perturbation to decipher how the key triggers sense, integrate and transmit signals to regulatory circuits that define cell states.

25 October 2024 Preis der Klüh Stiftung an Kathrin Thedieck
Den diesjährigen Preis zur Förderung der Innovation in Wissenschaft und Forschung der Klüh-Stiftung erhielt Prof. Dr. Kathrin Thedieck für ihre herausragende Forschungsarbeit über "Therapieansätze für die seltene Krankheit Tuberöse Sklerose". Die Wissenschaftlerin leitet die Abteilung für "Stoffwechsel, Seneszenz und Autophagie" am Research Center One Health der Universitätsallianz Ruhr. Gemeinsam mit ihrem Team untersucht sie Signalnetzwerke, die den Stoffwechsel und das Wachstum von Tumorzellen regulieren.
5 September 2024 Role of protein kinase PLK1 in the epigenetic maintenance of centromes
The latest paper from the Musacchio lab (A02), published in Science, sheds light on how the Polo-like kinase 1 (PLK1) coordinates the regeneration of the centromeres and the associated protein complex at the end of mitosis. This process is essential for the attachment of mitotic spindle microtubules to chromosomal centromeres and, therefore for the precise separation of chromosomes during cell division. By interacting with numerous proteins, PLK1 first induces phosphorylation of centromere-associated proteins and subsequently binds to the centromere itself. They revealed, that this binding leads to conformational changes that result in the recruitment of the histone H3-like centromeric protein A (CENP-A) and its chaperone Holliday junction recognition protein (HJURP).
29 August 2024 Alternating binding and p97-mediated dissociation of SDS22 and I3 recycles active PP1 between holophosphatases
The Meyer Lab has published a new paper in PNAS. Dephosphorylation of diverse cellular targets is catalyzed by Protein phosphatase-1. Its catalytic subunit (PP1) therefore joins diverse targeting subunits to form holophosphatases. During holophosphatase biogenesis newly synthesized PP1 is trapped in an inhibitory complex with Suppressor-of-Dis2-number-2 (SDS22) and Inhibitor-3 (I3). This inhibitory SDS22-PP1-I3 complex is then disassembled by the ATPases Associated with diverse cellular Activities plus (AAA+) protein p97. Using Förster Resonance energy transfer (FRET) analysis of labeled proteins they show, that this mechanism extends to mature PP1 and that cycles of SDS22-PP1-I3 formation and p97-driven disassembly regulate dynamic exchange of PP1 to match holophosphatase composition to changing physiological conditions.
05 July 2024 tracerDB: a crowdsourced fluorescent tracer database for target engagement analysis
Nature Communications has published a new paper by Martin P. Schwalm from the Knapp lab (B03). They have created a novel open access database, dubbed tracerDB, to provide the research community with a knowledge base and a unified system for tracer and assay validation. This curated database contains detailed information on key reagents and associated data. Hence, the database facilitates the investigation of ligand-protein complexes, which in turn is essential in the area of chemical biology and drug discovery. The database can be accessed freely at https://www.tracerdb.org/
May - December Sex and Gender in the Life Sciences
The new lecture series, “Sex and Gender in the Life Sciences,” aims to showcase perspectives on how research in the life sciences can utilize the analytical potential of the gender dimension. The CRC 1430, along with six other major DFG networks at the University of Duisburg-Essen, are participating in this innovative seminar series. This initiative is led by UDE’s strategic research area "Biomedical Sciences," represented by the Erwin L. Hahn Institute (ELH), the Center of Medical Biotechnology (ZMB), and the Essen College of Gender Research.
Every 6 weeks Women in Science Networking Event
The CRC 1430 invites you to our upcoming female scientists Get-Together!
This gathering is an excellent opportunity for the talented women of CRC 1430 to share their experiences in research, discuss strategies for advancing their careers, and build a supportive network. These dynamic sessions alternate every six weeks between the UKE "Casino" and the Essen campus "Brücke," offering a welcoming space to connect, exchange ideas, and empower each other in the scientific community.
Join us for our next get-together at “Casino” 23rd of October!
