<p><strong>Cells in the human body constantly evaluate signals from their surroundings and decide whether to divide, grow, or remain inactive. One of the key systems controlling this communication is the so-called Wnt signalling pathway. If this mechanism becomes disrupted, cells can spiral out of control, leading to uncontrolled growth and the development of tumours. Scientists from CEITEC and the Faculty of Science at Masaryk University have now described a critical decision-making process – the point at which a cell’s future development is decided. Their findings may, in the future, contribute to the search for ways to slow down or stop such processes in diseases like cancer.</strong></p><p>The <strong>Wnt signalling pathway</strong> is a mechanism that coordinates billions of cells in the body – it is responsible for the development of an entire organism from a single cell, and it continues to regulate tissue renewal throughout adult life. Until now, it was not fully understood how this mechanism works in detail. However, new research by teams from Masaryk University (MUNI) shows that the cells do not respond to stimuli smoothly, but rather operate in an on-off mode once a certain decision-threshold is crossed. This principle changes our understanding of how cells function together and helps explain situations in which cellular decision-making goes out of control and may lead to cancer development.</p><p>The process begins at the surface of the cell, where a signal is captured by a receptor embedded in the cell membrane. A protein called Dishevelled (DVL) then binds to this receptor and carries the signal further into the cell. However, for the signal to continue, DVL must first undergo a series of chemical modifications. Small chemical groups begin to accumulate on its surface, progressively increasing its negative charge.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Vedci_nasli_bod_zlomu_v_bunce_Prave_takto_muze_zacit_rakovina_4_7c8f80376d.jpg" alt="CEITEC/Tripsianes Lab: Scientists Uncover a Tipping Point in Cells.

Only then does it rearrange and allow the signal to proceed further,”</i> explains first author <a target="_blank" rel="noopener noreferrer" href="https://www.ceitec.eu/miroslav-micka/u92423?page=publication"><strong>Miroslav Micka</strong></a>.</p><p>At this point, DVL detaches from the receptor, allowing the signal to move deeper into the cell. The cell then receives a clear instruction on how to respond – for example, to start dividing or change its function.</p><p>This crucial “tipping point,” where the fate of the signal is decided, has so far been only partially understood: <i>“Scientists knew the pathway the signal follows, but they mostly viewed it as a gradual regulatory system. However, our teams have shown that it is rather a process based on decision points and abrupt changes once a certain threshold is crossed. This is important not only for understanding how cells function, but also for explaining what happens when these processes become dysregulated,”</i> add corresponding authors <a target="_blank" rel="noopener noreferrer" href="https://www.ceitec.eu/konstantinos-tripsianes-ph-d/u17552?page=publication"><strong>Konstantinos Tripsianes</strong></a><strong> from CEITEC MUNI</strong> and <a target="_blank" rel="noopener noreferrer" href="https://www.muni.cz/en/people/11088-vitezslav-bryja"><strong>Vítězslav Bryja</strong></a><strong> from the Faculty of Science</strong>.</p><p>Such decision points in cellular signalling are particularly important from a medical perspective, as their disruption can trigger processes that lead to tumour development.

Here, we uncovered a Wnt-induced DVL phospho-switch that is mutually exclusive with FZD association. CK1 multiphosphorylation changes dramatically the bulk electrostatics to promote DVL intramolecular interaction between the DEP domain and the adjacent disordered region. A panel of DVL3 mutants demonstrated a switch-like behavior at the molecular level when a charge threshold was reached. Charge accumulation proximal to DEP proved to be a key functional event required, but not sufficient, for Wnt/β-catenin signaling. Proximity interactomics revealed FZD receptors as the prominent effectors of the DVL phospho-switch function consistent with the molecular competition at the DEP interface. By integrating findings at different levels, we propose a universal mechanism, in which Wnt-induced DVL conformational phospho-switch attenuates coresidence with FZDs as a means for downstream signaling events.</p>

Despite their importance, widely used assays for DNA-editing enzymes are time-consuming and expensive. Here, we describe a new assay for DNA-editing enzymes in which the substrate in the reaction is a chemiluminescent deoxyribozyme called Supernova. Editing alters the sequence of Supernova, which results in a change in catalytic activity and light production. By analyzing a data set of Supernova variants previously identified by selection and high-throughput sequencing, it was possible to generate sensors with a wide range of specificities. Sensors were also developed for APOBEC3A, a cytidine deaminase which converts C to U in single-stranded DNA and RNA. These include a turn-off sensor that produces light 14-fold slower after incubation with recombinant APOBEC3A than in its absence, and a turn-on sensor that generates light 10-fold faster after incubation with APOBEC3A than in its absence. Assays that use these sensors are faster and less expensive than existing ones, and should be particularly useful for applications such as high-throughput screening.</p><blockquote><h4><a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acschembio.5c00969"><strong>Probing the Specificity of Fluorescent Deoxyribozymes Using Single-Step Selections and Machine Learning</strong></a></h4><p>Král’ová, Z.; Isler, L.; Volek, M.; Jandová, M.; Kurfürst, J.; Curtis, E.

Here, we systematically investigated the specificities of self-phosphorylating deoxyribozymes that convert the coumarin substrate 4-MUP into a fluorescent product using biochemical assays, single-step selections, and machine learning. Activity assays using a panel of 20 catalytic motifs and 10 substrates that generate different types of signals when they are dephosphorylated revealed that these deoxyribozymes are extremely specific for 4-MUP. To identify mutations that change specificity, we constructed a library based on a self-phosphorylating fluorescent deoxyribozyme called Aurora. A series of single-step selections yielded variants that react with 4-MUP and the structurally similar substrate diFMUP, but not with the more distinct substrates pNPP and ELF. Pairwise analysis of sequences in the 4-MUP and diFMUP data sets revealed four mutations that modulate Aurora specificity. The effects of these mutations were confirmed using biochemical assays and could be predicted using models developed by machine learning. Taken together, our results show how single-step selections can be used to identify mutations that change the specificity of a deoxyribozyme. They also highlight how machine learning can be used to model complex data sets from <i>in vitro</i> selection experiments.</p></div></div>

Drawing on more than 15 years of experience in LC-MS and protein mass spectrometry, she shares insights into peptide characterization, impurity profiling, workflow continuity, and the growing role of AI in analytical science.</p><h4><strong>Kelly's Background in Biopharmaceutical Analysis</strong></h4><p>Kelly currently focuses on biopharmaceutical development at Thermo Fisher Scientific, working closely with industry partners to transform complex analytical challenges into scalable and compliant workflows. Her scientific background includes cancer biology, quantitative proteomics, biomarker assays, systems oncology, and mass spectrometry-based drug discovery. Throughout her academic and industrial career, she has applied mass spectrometry to support patient stratification, treatment monitoring, and therapeutic development.</p><h4><strong>Why GLP-1 Therapeutics Are So Important Right Now</strong></h4><p>GLP-1 drugs have become one of the most discussed therapeutic classes because they occupy a unique space between traditional small molecules and large biologics. Their structural complexity, sensitivity to degradation, and global manufacturing scale make them an ideal example of how analytical science must evolve.</p><p>According to Kelly, these molecules require greater analytical sensitivity, deeper structural characterization, and seamless workflows that support everything from discovery through manufacturing and regulatory submission.</p><h4><strong>Analytical Challenges of Peptide Therapeutics</strong></h4><p>Unlike conventional small molecules, peptide drugs such as semaglutide are larger, conformationally dynamic, and often chemically modified to improve stability, half-life, and absorption.</p><p>These therapeutics may contain:</p><ul><li>Sequence variants</li><li>Oxidation products</li><li>Deamidation products</li><li>Aggregates</li><li>Trace-level impurities</li></ul><p>Many of these species are difficult to separate chromatographically and challenging to identify confidently. As a result, peptide characterization requires both highly selective chromatography and high-resolution accurate-mass spectrometry.</p><h4><strong>What GLP-1 Drugs Teach Us About the Future of Analytical Science</strong></h4><p>Kelly emphasized that the future of analytical science is not necessarily about generating more data but about measuring the right attributes earlier and with greater confidence.</p><p>GLP-1 developers increasingly require integrated analytical workflows that generate actionable insights during discovery while remaining robust enough to support late-stage development, manufacturing, and global regulatory filings. This trend highlights the growing importance of scalable and harmonized analytical ecosystems.</p><h4><strong>Why Small Molecular Changes Matter</strong></h4><p>Even a single amino acid substitution or post-translational modification can dramatically alter a peptide's biological behavior.</p><p>Minor structural changes may affect:</p><ul><li>Receptor binding</li><li>Potency</li><li>Stability</li><li>Immunogenicity</li></ul><p>Because these changes can directly influence safety and efficacy, regulatory agencies require precise structural characterization and control throughout development and manufacturing.</p><h4><strong>The Power of Combining Chromatography and Mass Spectrometry</strong></h4><p>For complex peptide therapeutics, chromatography and mass spectrometry work together to provide comprehensive characterization.</p><p>Chromatography separates complex mixtures and resolves closely related species, while high-resolution mass spectrometry provides molecular specificity and structural confirmation. Together, advanced UHPLC and HRAM MS deliver the selectivity, sensitivity, and confidence required for modern peptide analysis.</p><h4><strong>The Value of High-Resolution Accurate-Mass Spectrometry</strong></h4><p>Kelly described high-resolution accurate-mass (HRAM) mass spectrometry as an indispensable technology for drug development.</p><p>Compared with older analytical approaches, HRAM provides:</p><ul><li>Exact mass measurements</li><li>Isotopic resolution</li><li>Structural confirmation</li><li>Trace impurity detection</li><li>Identification of sequence variants</li><li>Characterization of post-translational modifications</li></ul><p>These capabilities enable confident data generation that can withstand regulatory scrutiny, audits, and global submissions.</p><h4><strong>Why Sensitivity Is Critical</strong></h4><p>The distinction between a safe and unsafe therapeutic can exist at extremely low concentration levels.</p><p>Detecting impurities at parts-per-billion levels allows developers to identify risks early in development and address them before manufacturing scale-up. Analytical sensitivity therefore supports both regulatory confidence and patient safety.</p><h4><strong>Resolving Co-Eluting Impurities</strong></h4><p>One of the greatest challenges in peptide analysis is distinguishing nearly identical molecular species.</p><p>By combining ultra-high-resolution mass spectrometry with optimized chromatographic separations, scientists can accurately differentiate closely related compounds and remove uncertainty from impurity profiling. This capability is essential for both regulatory submissions and therapeutic safety assessments.</p><h4><strong>Workflow Continuity Across Drug Development</strong></h4><p>Kelly stressed that analytical methods should not be reinvented at every stage of development.</p><p>Instead, workflows should transition smoothly from:</p><ul><li>Research and discovery</li><li>Development</li><li>Quality control</li><li>Manufacturing</li></ul><p>Maintaining continuity improves reproducibility, preserves data integrity, and enables scalable development without disrupting analytical performance.</p><h4><strong>The Evolution of Instruments, Software, and Data Platforms</strong></h4><p>Modern analytical ecosystems extend beyond LC-MS instrumentation alone.</p><p>Today's workflows integrate:</p><ul><li>Consumables</li><li>Chromatography systems</li><li>Mass spectrometers</li><li>Informatics platforms</li></ul><p>Instrumentation continues to become faster, more sensitive, and capable of higher throughput, while advanced software transforms complex datasets into actionable insights. These integrated platforms support compliance, traceability, and harmonized global operations.</p><h4><strong>Data Integrity and Regulatory Compliance</strong></h4><p>As drug development becomes increasingly global, maintaining data integrity is more important than ever.</p><p>Validated software systems, secure data management tools, and comprehensive audit trails help organizations harmonize workflows across multiple sites while ensuring that generated data can withstand regulatory review worldwide.</p><h4><strong>Lessons for Next-Generation Biologics</strong></h4><p>Although GLP-1 therapeutics are currently in the spotlight, Kelly believes the broader lesson is that molecular complexity is increasing across all therapeutic classes.</p><p>This includes:</p><ul><li>Peptides</li><li>Monoclonal antibodies</li><li>Fusion proteins</li><li>Advanced biologics</li></ul><p>Across all these modalities, the need for deeper molecular understanding, early risk detection, and scalable analytical control continues to grow.</p><h4><strong>Biosimilars, Generics, and Equivalence Testing</strong></h4><p>As GLP-1 patents expire, analytical science will play a crucial role in establishing biosimilarity and equivalence.</p><p>Developers must demonstrate rigorous structural and functional comparability between original products and follow-on versions. High-resolution analytical platforms provide the depth of characterization required to prove equivalence while protecting patient safety and therapeutic efficacy.</p><h4><strong>Future Opportunities in Chromatography and Mass Spectrometry</strong></h4><p>Looking ahead, Kelly sees significant innovation opportunities in:</p><ul><li>Greater integration of analytical platforms</li><li>Faster chromatographic separations</li><li>Enhanced multiplexing</li><li>Smarter data analytics</li><li>Increased automation</li><li>Real-time process monitoring</li><li>Process analytical technologies (PAT)</li></ul><p>These developments will bring analytical insights closer to manufacturing environments and improve efficiency across the drug development lifecycle.</p><h4><strong>The Next 5–10 Years</strong></h4><p>Over the next decade, Kelly expects analytical workflows to become:</p><ul><li>More predictive</li><li>More automated</li><li>More interconnected</li><li>Increasingly supported by AI-driven interpretation</li></ul><p>However, she emphasized that these advances must remain grounded in high-quality analytical data generated by ultra-high-resolution instrumentation.</p><h4><strong>Final Thoughts</strong></h4><p>Kelly concluded by highlighting the critical role analytical scientists play in enabling patient access to safe and effective medicines. By identifying hidden risks, characterizing complex molecules, and supporting innovation without compromising scientific rigor, analytical science remains a cornerstone of modern drug development and aligns directly with Thermo Fisher Scientific's mission of making the world healthier, cleaner, and safer.</p><blockquote><p><strong>This text has been automatically transcribed from a video presentation using AI technology.
