Catechol Containing Polyelectrolyte Complex Nanoparticles as Local Drug Delivery System for Bortezomib at Bone Substitute Materials

Martin Guillermo Mueller, Jeremy Pak Hei Wong

The proteasome inhibitor bortezomib (BZM) is one of the most potent anti-cancer drugs in the therapy of multiple myeloma. In this study, an adhesive drug delivery system (DDS) for BZM was developed. Therefore, we extended the present DDS concept of polyele ...

Selective inhibition of STAT3 signaling using monobodies targeting the coiled-coil and N-terminal domains

Florence Pojer, Kelvin Ka Ching Lau, Oliver Hantschel, Grégory La Sala

The transcription factor STAT3 is frequently activated in human solid and hematological malignancies and remains a challenging therapeutic target with no approved drugs to date. Here, we develop synthetic antibody mimetics, termed monobodies, to interfere ...

Proteasomal and lysosomal clearance of faulty secretory proteins: ER-associated degradation (ERAD) and ER-to-lysosome-associated degradation (ERLAD) pathways

Maurizio Molinari

About 40% of the eukaryotic cell's proteins are inserted co- or post-translationally in the endoplasmic reticulum (ER), where they attain the native structure under the assistance of resident molecular chaperones and folding enzymes. Subsequently, these pr ...

Schwann cells ER-associated degradation contributes to myelin maintenance in adult nerves and limits demyelination in CMT1B mice

Maurizio Molinari, Francesca Bianchi

In the peripheral nervous system (PNS) myelinating Schwann cells synthesize large amounts of myelin protein zero (P0) glycoprotein, an abundant component of peripheral nerve myelin. In humans, mutations in P0 cause the demyelinating Charcot-Marie-Tooth 1B ...

Targeted protein degradation through cytosolic delivery of monobody binders using bacterial toxins

Oliver Hantschel, Nadine Eliane Schmit, Katyayanee Neopane

Monobodies are small engineered binding proteins that, upon expression in cells, can inhibit signaling of cytosolic oncoproteins with outstanding selectivity. Efficacy may be further increased by inducing degradation of monobody targets through fusion to t ...

Analysis of the S. pombe Meiotic Proteome Reveals a Switch from Anabolic to Catabolic Processes and Extensive Post-transcriptional Regulation

Viesturs Simanis, Romain Hamelin, Andrea Krapp, Florence Armand, Diego Chiappe, Lucien Fabrice Krapp, Marc Moniatte, Elena Cano

Meiotic progression in S. pombe is regulated by stage-specific gene expression and translation, changes in RNA stability, expression of anti-sense transcripts, and targeted proteolysis of regulatory proteins. We have used SILAC labeling to examine the rela ...

Proteomics and Beyond: Cell Decision-Making Shaped by Reactive Electrophiles

Yimon Aye, Xuyu Liu

Revolutionary proteomic strategies have enabled rapid profiling of the cellular targets of electrophilic small molecules. However, precise means to directly interrogate how these individual electrophilic modifications at low occupancy functionally reshape ...

Cryo-EM structures of the pore-forming A subunit from the Yersinia entomophaga ABC toxin

Henning Paul-Julius Stahlberg

ABC toxins are pore-forming virulence factors produced by pathogenic bacteria. YenTcA is the pore-forming and membrane binding A subunit of the ABC toxin YenTc, produced by the insect pathogen Yersinia entomophaga. Here we present cryo-EM structures of Yen ...

Single Live Cell Monitoring of Protein Turnover Reveals Intercellular Variability and Cell-Cycle Dependence of Degradation Rates

Felix Naef, David Michael Suter, Eric Paquet, Andrea Brigitta Alber, Martina Biserni

Cells need to reliably control their proteome composition to maintain homeostasis and regulate growth. How protein synthesis and degradation interplay to control protein expression levels remains unclear. Here, we combined a tandem fluorescent timer and pu ...

Chemical Ligand Space of Cereblon

Iuliia Boichenko

The protein cereblon serves as a substrate receptor of a ubiquitin ligase complex that can be tuned toward different target proteins by cereblon-binding agents. This approach to targeted protein degradation is exploited in different clinical settings and h ...
