Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from deoxyribonucleic acid (DNA) into ribonucleic acid (RNA) can be initiated. The researchers focused on a specific class of molecules known as alarmones, which are found in cells across a wide range of organisms and whose levels often increase under conditions of cellular stress. The results were published in the prestigious scientific journal Nature Chemical Biology.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_bc2bfffa6c.jpg" alt="IOCB Prague/Tomáš Belloň: Research from IOCB Prague reveals a previously unknown mechanism of genetic transcription: Dr. Hana Cahová, head of the Chemical Biology of Nucleic Acids research group." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_bc2bfffa6c.jpg 234w," sizes="100vw" width="2000" height="1335"><div>Molecules of ribonucleic acid can carry a variety of chemical modifications at one end, known as caps. In eukaryotic organisms, including human cells, the best-known cap plays an important role in RNA stability and in regulating its subsequent fate. In recent years, however, it has become clear that alternative, non-canonical RNA caps also exist, although their formation and the mechanisms by which they are attached to RNA remain only partially understood. These include alarmone caps, formed by dinucleoside polyphosphate molecules, that protect cellular RNA at moments when the cell is under threat.In their study, <a target="_blank" rel="noopener noreferrer" href="https://cahova.group.uochb.cz/en">Dr. Hana Cahová</a> and colleagues examined bacterial RNA polymerase and investigated how this enzyme can initiate transcription using dinucleoside polyphosphates (NpNs) instead of the standard RNA building blocks. For the first time, the scientists described, at the atomic level, how RNA bearing an alarmone cap can be generated directly at the initiation of gene transcription. They also observed that NpNs bind through a different type of base pairing than is typically observed.The work was significantly shaped by Valentina Serianni from Hana Cahová’s team, who demonstrated the ability of dinucleoside polyphosphates to initiate gene transcription, and by Jana Škerlová, who focused on the structural analysis of RNA polymerase. Using cryogenic electron microscopy data, she showed how dinucleoside polyphosphate molecules bind within the active site of RNA polymerase – that is, the core of the enzyme where genetic information is transcribed. Together, their findings help to elucidate the processes that accompany the transcription of genetic information from DNA to RNA.Hana Cahová adds: “We’re describing something that truly occurs in cells and that we’re now able to observe directly at the level of individual molecules. This allows us to answer fundamental questions about cellular processes, such as how cells adapt to stress. RNA plays a central role in this, as it carries the cascade of information underlying any cellular response – for example, to threatening conditions caused by nutrient deprivation or temperature shock.”<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_2_0fe88ff9e9.jpg" alt="IOCB Prague/Tomáš Belloň: Research from IOCB Prague reveals a previously unknown mechanism of genetic transcription: Dr. Tomáš Kouba, head of the Cryogenic Electron Microscopy core facility." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_2_0fe88ff9e9.jpg 234w," sizes="100vw" width="2000" height="1335"><div>Cryogenic electron microscopy (cryo-EM) was central to the project.

The likely mechanism of this specific capping involves direct incorporation of dinucleoside polyphosphates by RNA polymerase as noncanonical initiating nucleotides. However, how these compounds bind into the active site of RNA polymerase during transcription initiation is unknown. Here, we explored transcription initiation in vitro, using a series of DNA templates in combination with dinucleoside polyphosphates and model RNA polymerase from Thermus thermophilus. We observed that the transcription start site can vary on the basis of the compatibility of the specific template and dinucleoside polyphosphate. Cryo-electron microscopy structures of transcription initiation complexes with dinucleoside polyphosphates revealed that both nucleobase moieties can pair with the DNA template. The first encoded nucleotide pairs in a canonical Watson–Crick manner, whereas the second nucleobase pairs noncanonically in a reverse Watson–Crick manner. Our work provides a structural explanation of how dinucleoside polyphosphates initiate RNA transcription.</div></div>

Food adulteration is a phenomenon with a long history that has gained increasing importance in recent years due to the globalization of food supply chains and strong economic pressures. Whether it involves diluting olive oil with cheaper oils, adding sugar to honey, or the hidden use of substitutes in protein supplements, the result is a loss of consumer trust and, in some cases, a potential risk to health. Analytical chemistry plays a key role in this area by providing methods and technologies capable of identifying and quantifying target compounds as well as unwanted impurities in a wide range of food matrices.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Watrex_Praha_Falsovani_potravin_a_jak_ho_odhali_analyticka_chemie_6912db5492.jpg" alt="Watrex: Food Adulteration and How It Is Revealed by Analytical Chemistry" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Watrex_Praha_Falsovani_potravin_a_jak_ho_odhali_analyticka_chemie_6912db5492.jpg 245w," sizes="100vw" width="1600" height="900"><h4>The Role of Chromatography in Forensic Food Analysis</h4>Chromatography, particularly liquid chromatography (HPLC), is one of the most effective analytical tools for separating complex mixtures of molecules. It enables:<ul><li>qualitative identification of individual components in a sample,</li><li>quantitative determination of their concentrations,</li><li>detection of impurities and unexpected components that may indicate adulteration.</li></ul>In practice, HPLC is often combined with various types of detectors (UV/VIS, DAD, refractive index detectors) or with other techniques (e.g., mass spectrometry) to increase selectivity and sensitivity.<h4>Isocratic vs. Gradient Elution</h4>In the analysis of food samples, chromatographic methods are selected according to the analytical goal:<ul><li>Isocratic HPLC uses a constant mobile phase composition throughout the analysis. It is simple, robust, and ideal for routine determinations of well-defined target analytes (e.g., sugars or vitamins).</li><li>Gradient HPLC changes the mobile phase composition during separation, enabling better resolution of complex mixtures with a wide range of polarities (e.g., peptides or phenolic compounds).</li></ul>Gradient methods are particularly useful when analytes have very different properties and high separation efficiency is required.<h4>Watrex Praha and the Contribution of Modern Systems to Food Analysis</h4><a target="_blank" rel="noopener noreferrer" href="https://watrex.com/?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_clanky_HPLCsystemy">Watrex Praha, s.r.o.</a> is one of the leading Czech manufacturers and distributors of liquid chromatography systems and instruments, with a long tradition dating back to 1990.

The conversation is aimed primarily at undergraduate students and early-career researchers interested in chemistry, biotechnology, and life sciences.<h5>Research Focus: Malaria Drug Discovery and Kinase Targets</h5>Subhoja is currently involved in malaria drug discovery research at the University of Central Florida, where she has been working since beginning her postdoctoral position two years ago. Her earlier PhD research focused on structure-based drug design in malaria, using a combination of in silico approaches, recombinant protein expression, and X-ray crystallography to determine precise three-dimensional structures of target proteins and their inhibitors.This structural perspective provided a foundation for her current work, which centers on drug discovery through compound screening and repurposing. A recent publication from her laboratory explores the use of repurposed mammalian CDK-like kinase inhibitors as potential antimalarial agents. While such kinase inhibitors are well known in cancer and cardiovascular research, their application to malaria targets represents a novel and promising approach.Kinases are attractive drug targets because of their central role in cell signaling and growth pathways. By targeting specific kinases involved in different stages of the malaria parasite life cycle—whether asexual growth, gametocytogenesis, or differentiation—it may be possible to significantly inhibit parasite growth and progression.<h5>Chromatography in Protein Expression and Purification Workflows</h5>Chromatography plays a critical role throughout Subhoja’s research. Her experience spans from basic chromatography techniques during her early training to advanced protein purification workflows using affinity chromatography, gel filtration (size exclusion chromatography), and ion exchange chromatography.Recombinant proteins are routinely purified using affinity resins such as nickel or cobalt, followed by further purification to remove contaminants. Fast Protein Liquid Chromatography (FPLC) enables compact, stepwise purification workflows suitable for producing proteins for in vitro assays.A recurring challenge in this process is the expression of high-molecular-weight proteins, which often accumulate in insoluble fractions or inclusion bodies. Careful selection of expression vectors, host systems, and induction conditions is therefore essential to maximize yield and solubility.<h5>Integrating Size Exclusion Chromatography into the Workflow</h5>Size exclusion chromatography (SEC) is typically used after affinity purification to further improve protein purity. Following elution with imidazole or glutathione, desalting is required to prevent buffer components from interfering with downstream assays. This is often achieved using desalting columns such as G-25 or PD-10.To remove lower-molecular-weight contaminants, finer SEC media—such as Superdex or Sephacryl columns—are employed. Concentration steps using molecular-weight cut-off filters are then applied to obtain the desired protein concentration for functional studies.These iterative purification and troubleshooting steps are a routine part of protein biochemistry and reflect the importance of methodical optimization and careful validation.<h5>The Role of Mass Spectrometry in Biomolecular Characterization</h5>Mass spectrometry is a key analytical tool in Subhoja’s research pipeline, particularly for target identification and validation. In both malaria and cancer research, MS is used alongside chromatography, immunoprecipitation, and pull-down assays to study protein interactions and molecular recognition events.Affinity-based mass spectrometry enables the identification of binding partners and interactors, whether studying proteins, long non-coding RNAs, or protein complexes. Techniques such as native MS, tandem affinity purification, and proximity labeling (e.g., TurboID-based workflows) provide deeper insights into molecular networks and signaling pathways.These approaches are essential for understanding how candidate drug targets function within complex biological systems.<h5>Sample Preparation Challenges in Biological Research</h5>Sample preparation remains one of the most challenging aspects of biological experimentation. Whole-cell lysates contain proteases, nucleases, and other components that can rapidly degrade target molecules. Preventing degradation requires minimizing preparation time, maintaining low temperatures, and using appropriate inhibitor cocktails.Reproducibility is also critical: biological experiments require multiple replicates, and variability is often unavoidable. Careful handling, protocol optimization, and continuous troubleshooting are essential to ensure reliable results, whether preparing samples for chromatography, mass spectrometry, sequencing, or immunoprecipitation.<h5>Advances in Chromatography and MS for Malaria Research</h5>Modern advances in chromatography and mass spectrometry significantly enhance malaria research by enabling precise target identification, quantification, and functional characterization. Drug discovery workflows begin with construct design and recombinant expression, followed by purification and interaction studies.In malaria research, stage-specific parasite biology requires careful extraction and analysis of proteins from different life cycle stages. Tandem affinity MS, immunoprecipitation, and in vivo validation studies help confirm target relevance and therapeutic potential.Recent work on repurposed kinase inhibitors has shown promising results, including inhibition of hemozoin formation—a key detoxification pathway for the malaria parasite—highlighting the potential of such compounds for further development.<h5>Malaria, Drug Resistance, and Global Impact</h5>Malaria remains a major global health burden, with over 600,000 deaths annually and widespread drug resistance complicating treatment. Artemisinin resistance, particularly associated with mutations in the K13 propeller domain, has driven the search for new targets and therapies.During her PhD, Subhoja focused on falcipain-2, a cysteine protease involved in hemoglobin degradation within the parasite. This pathway is critical for parasite survival and has emerged as a promising drug target. Her work revealed that falcipain-2 operates within a larger protein complex responsible for hemoglobin processing and amino acid release.Understanding these molecular mechanisms is essential for developing robust, stage-specific antimalarial strategies.<h5>Advice for Early-Career Researchers</h5>For researchers just starting out, Subhoja emphasizes the importance of hands-on experience. Working directly with cells, lysates, and analytical tools is essential for truly understanding experimental systems. Failure is an inherent part of research, and perseverance is key.Motivation, teamwork, careful sample handling, and thorough preparation all contribute to long-term success. Reading extensively, critically evaluating one’s own work, and appreciating incremental progress are vital aspects of a sustainable research career.Every successful experiment—no matter how small—represents meaningful progress and contributes to the broader goals of science and medicine.<h5>Closing Remarks</h5>The discussion highlights how interdisciplinary approaches combining chromatography, mass spectrometry, structural biology, and biochemistry are driving advances in malaria drug discovery. Through careful experimental design, analytical rigor, and collaborative teamwork, researchers can address complex biological challenges and contribute to global health solutions.<blockquote>This text has been automatically transcribed from a video presentation using AI technology.

The Latest Innovations in Mass Spectrometry

Join this webinar to explore the utility of hydrogen in chemical research, its associated risks, and a safer laboratory solution: H-Genie® Lite. This innovative, compact hydrogen generator employs unique patented cell technology to convert water into high-purity hydrogen gas, reaching pressures up to 50 bar (725 psi). As an ideal replacement for conventional hydrogen cylinders, it not only boosts lab safety but is also perfect for filling autoclaves and pressured containers.
Subsequently, we will delve into metal-catalyzed hydrogenation reactions. Heterogeneous catalysts like Pd/C are commonly employed for nitro group reductions and hydrogenation of carbon-carbon and carbon-heteroatom double bonds. These catalysts also aid in O- and N- deprotection, yielding respective alcohols or amines, and in asymmetric hydrogenation reactions.
We’ll discuss the core principles of hydrogenation, featuring both heterogeneous and homogeneous catalysts, and highlight their significance in industrial applications. H-Genie® Lite seamlessly integrates with both batch and continuous flow chemistry hydrogenation processes.

Laboratories rely on efficiency, safety, and cost-effectiveness to optimize their workflows. One of the most significant factors in achieving these goals is ensuring a reliable supply of nitrogen gas. Organomation’s latest webinar, Improving Laboratory Workflows through Nitrogen Generation, explores how nitrogen generators can revolutionize lab operations by eliminating the need for gas cylinders.<h4>The Challenge: Gas Cylinders vs. On-Site Nitrogen Generation</h4>Traditionally, many laboratories depend on nitrogen cylinders, which come with hidden costs and logistical challenges.&nbsp;These include:<ul><li>Rental Fees: The recurring costs of renting cylinders add up over time.</li><li>Refill and Delivery Charges: Market fluctuations and scheduling conflicts can delay deliveries, leading to downtime.</li><li>Safety Concerns: Handling and transporting high-pressure cylinders can pose workplace hazards.</li><li>Space Limitations: Storing multiple bulky cylinders takes up valuable lab space.</li></ul>Organomation’s David Oliva shared a real-world example of a lab located in a multi-floor building without an elevator. Employees were forced to carry heavy gas cylinders up and down staircases, creating an unnecessary safety risk. Another lab experienced a several-week delay in research due to a miscommunication in their cylinder delivery. Situations like these highlight the need for a more reliable and efficient solution.<h4>The Solution: On-Site Nitrogen Generation</h4>Nitrogen generators provide labs with a cost-effective, continuous nitrogen supply while addressing many of the pain points associated with gas cylinders.Key benefits include:<ul><li>Significant Cost Savings: Eliminates rental, refill, and delivery fees.</li><li>Operational Efficiency: Reduces workflow disruptions by ensuring an uninterrupted nitrogen supply.</li><li>Enhanced Safety &amp; Convenience: Removes the need to store and handle high-pressure cylinders.</li><li>Space Optimization: Compact generators free up valuable lab space.</li><li>Sustainability: Reduces the environmental impact associated with nitrogen gas transportation.</li></ul>To help labs assess whether a nitrogen generator is a worthwhile investment, Organomation has developed a payback calculator. Many labs find that they achieve a full return on investment within 1-2 years.<h3>Real-World Success Stories</h3>Several laboratories have already made the switch to nitrogen generators, experiencing improved efficiency and cost savings.<h4>Temple University’s McKenzie Environmental Engineering Research Group</h4>Temple University’s research group, which concentrates PFAS sample extracts for mass spectrometry, made the transition to nitrogen generation to combat rising costs associated with tank rentals, delivery, and surcharges. Their investment in the NITRO-GEN generator allowed them to meet growing sample throughput requirements without the logistical headaches of cylinder replacements. With a compact design and plug-and-play functionality, the generator seamlessly integrated into their workflow.<h4>Moyo Lab at Louisiana State University</h4>The Moyo Lab, which studies nutrient movement across habitats, relies on nitrogen evaporation to remove excess chloroform from their extraction samples. Dissatisfied with nitrogen cylinders, they opted for the NITRO-GEN+ generator to streamline their operations.Lab Manager and Assistant Professor of Biology Sydney Moyo shared his experience:"I love the NITRO-GEN+ for many reasons. First, a vital benefit is that I can move the generator around the department because it has wheels. When I used cylinders, I had difficulty moving them around the lab. Second, when the NITRO-GEN+ is not in use, I can safely store it in a corner in my lab because it only takes up a little space. Third, the NITRO-GEN+ is also very quiet and is one of the quietest generators we have used in the lab. Fourth, I love that there is less risk of running out of nitrogen as I always have a 24/7 supply when needed. Lastly, the NITRO-GEN+ is so easy to use that students in the Moyo Lab can use it with little training.”With user-friendly features and portability, the NITRO-GEN+ has proven to be a game-changer for the Moyo Lab, ensuring they never run out of nitrogen while simplifying lab operations.<h4>Making the Right Choice for Your Lab</h4>To assist labs in selecting the best nitrogen generator for their needs, Organomation offers a generator recommendation chart that matches evaporator models with the most suitable generator options. Additionally, their customer service team is always available to help labs find the best solution for their workflow requirements.<blockquote>Presenter: David Oliva (General Manager of Organomation)One of Oliva’s favorite responsibilities is visiting academic institutions and environmental laboratories around the world.
