<p><strong>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.

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.</p><p>In their study,<strong> </strong><a target="_blank" rel="noopener noreferrer" href="https://cahova.group.uochb.cz/en"><strong>Dr. Hana Cahová</strong></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.</p><p>The work was significantly shaped by <strong>Valentina Serianni from Hana Cahová’s team</strong>, who demonstrated the ability of dinucleoside polyphosphates to initiate gene transcription, and by <strong>Jana Škerlová</strong>, who focused on the structural analysis of RNA polymerase.

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 <i>Thermus</i> <i>thermophilus</i>. 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.</p></div></div>

The conversation is aimed primarily at undergraduate students and early-career researchers interested in chemistry, biotechnology, and life sciences.</p><h5><strong>Research Focus: Malaria Drug Discovery and Kinase Targets</strong></h5><p>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.</p><p>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.</p><p>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.</p><h5><strong>Chromatography in Protein Expression and Purification Workflows</strong></h5><p>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.</p><p>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.</p><p>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.</p><h5><strong>Integrating Size Exclusion Chromatography into the Workflow</strong></h5><p>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.</p><p>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.</p><p>These iterative purification and troubleshooting steps are a routine part of protein biochemistry and reflect the importance of methodical optimization and careful validation.</p><h5><strong>The Role of Mass Spectrometry in Biomolecular Characterization</strong></h5><p>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.</p><p>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.</p><p>These approaches are essential for understanding how candidate drug targets function within complex biological systems.</p><h5><strong>Sample Preparation Challenges in Biological Research</strong></h5><p>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.</p><p>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.</p><h5><strong>Advances in Chromatography and MS for Malaria Research</strong></h5><p>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.</p><p>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.</p><p>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.</p><h5><strong>Malaria, Drug Resistance, and Global Impact</strong></h5><p>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.</p><p>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.</p><p>Understanding these molecular mechanisms is essential for developing robust, stage-specific antimalarial strategies.</p><h5><strong>Advice for Early-Career Researchers</strong></h5><p>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.</p><p>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.</p><p>Every successful experiment—no matter how small—represents meaningful progress and contributes to the broader goals of science and medicine.</p><h5><strong>Closing Remarks</strong></h5><p>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.</p><blockquote><p><strong>This text has been automatically transcribed from a video presentation using AI technology.

Characteristics of monoclonal antibodies (Bioanalytic)

At LabExperts, proteomic analyses are performed on a ZenoTOF 7600 high-resolution LC-MS/MS system (SCIEX). For MS/MS analyses, we use Collision induced dissociation (CID) and Electron-Activated Dissociation (EAD) fragmentation.

<p><strong>Antibodies are molecules made up of 4 polypeptide chains: two heavy (H - high-chain) linked to each other by a specific type of chemical bond - a disulfide bridge, and two light (L - light-chain) linked by an identical bond to the heavy chains. Monoclonal antibodies (mABs) are used in various forms - as free molecules, in the form of a drug-antibody combination, and in the form of an immunoconjugate, a drug-antibody-biopolymer combination.</strong></p><p>Their main use is in highly specific targeted therapy for cancer, cardiovascular, autoimmune and nervous system diseases. They are also used in the treatment of osteoporosis, Alzheimer's disease or transplantation. The range of applications of monoclonal antibodies is systematically expanded. The introduction of a new antibody to the market requires complex product characterization, which involves numerous proteomic analyses, which are performed by LC-MS/MS techniques, among others.</p><h4><strong>LC-MS/MS</strong></h4><p>The characterization of monoclonal antibodies involves many aspects, including, but not limited to, a suite of analyses related to confirmation of the structure, chain sequence and degree of modification of the antibody. Post-translational modifications (PTMs) are chemical changes that occur after the translation process. These changes generally result in an increase in the immunogenicity of the drug. For this reason, it is essential to monitor modifications as critical quality attributes (CQAs) during both the production and storage of the drug. To ensure monitoring of CQA points, the primary structure of the protein is characterized based on peptide mapping (peptide mapping) analysis. The protein under study is subjected to proteolytic digestion using enzymes such as trypsin, chymotrypsin, Lys-C, Glu-C. As a result of various proteolytic enzymes, a wide range of peptides is obtained. Ultimately, coverage of the entire sequence of the protein under study is obtained.</p><figure class="image"><img style="aspect-ratio:1536/947;" src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Bioanalytic_Bioanalytic_Characteristics_of_monoclonal_antibodies_3_d94fa1623b.jpg" alt="Bioanalytic: Characteristics of monoclonal antibodies." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Bioanalytic_Bioanalytic_Characteristics_of_monoclonal_antibodies_3_d94fa1623b.jpg 245w," sizes="100vw" width="1536" height="947"></figure><p>At LabExperts, proteomic analyses are performed on a <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?manufacturerItems=52&amp;search=ZenoTOF+7600"><strong>ZenoTOF 7600</strong></a> high-resolution LC-MS/MS system (SCIEX).

Analysis of Anabolic steroids (Bioanalytic)

We offer a highly specific and sensitive qualitative analysis of a wide profile of anabolics by LC-HR-MS/MS technique (detection limits range from 0.01 to 5 ng/ml, depending on the substance).

<h4><strong>Anabolic substances in urine</strong></h4><p>The effect of anabolic steroids (<a target="_blank" rel="noopener noreferrer" href="https://en.wikipedia.org/wiki/Anabolic_steroid"><strong>more information</strong></a>) is to stimulate the growth of muscle mass and sometimes also bone mass by stimulating protein synthesis or altering calcium metabolism. This effect is often used in sports doping. However, anabolic steroids also have many side effects, as they strongly affect the body's overall hormonal balance.</p><p>Anabolic steroids used by purely recreational athletes are still not banned in most countries, including Poland. Nevertheless, their amateur use during adolescence often results in the inability to continue a professional sports career into adulthood or leads to hormonal imbalances in the body.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Bioanalytic_Analysis_of_Anabolic_steroids_Bioanalytic_1_46fa2f41ca.jpg" alt="Bioanalytic: Analysis of Anabolic steroids." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Bioanalytic_Analysis_of_Anabolic_steroids_Bioanalytic_1_46fa2f41ca.jpg 245w," sizes="100vw" width="1200" height="740"></p><p>If you want to know whether and which anabolic substances are present in the samples of athletes, or you want to exclude doping in this area - use the offer carried out by us together with the company <a target="_blank" rel="noopener noreferrer" href="http://www.lab4tox.pl/"><strong>Lab4Tox</strong></a>.

Identification of the proteins (Bioanalytic)

We perform proteomic analyses on a state-of-the-art high-resolution ZenoTOF 7600 (SCIEX), in which the Zeno ion trap and EAD (Electron-Activated Dissociation) technology together make a powerful combination.

<p><strong>Protein identification is based on experimental measurement of peptide molecular weights and matching the amino acid sequence of the protein under study with protein sequences deposited in libraries (databases). Two approaches are most commonly used in proteomic studies: top-down and bottom-up. The top-down method involves analyzing full protein sequences. Bottom-up analyses, on the other hand, use digestion of proteins with proteolytic enzymes. The peptides obtained by digestion are analyzed using a mass spectrometer. Each analysis leads to a comparison of experimental data with data obtained by theoretical digestion of proteins described in the database.</strong></p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Bioanalytic_Identification_of_the_proteins_Bioanalytic_2_6231b73f0d.jpg" alt="Bioanalytic: Identification of the proteins." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Bioanalytic_Identification_of_the_proteins_Bioanalytic_2_6231b73f0d.jpg 245w," sizes="100vw" width="1536" height="766"></p><h4><strong>LC-MS/MS</strong></h4><p>Tandem mass spectrometers are commonly used to determine protein sequences. They allow ion selection of pseudomolecular peptides and then fragmentation and measurement of the masses of the resulting fragments. Fragmentation using <i>collision induced dissociation</i>(CID ) is an invaluable tool in targeted and untargeted MS/MS analysis of small molecules. It is important to note that in proteomic analysis, data obtained using the aforementioned fragmentation method may leave gaps. For example, spectra obtained by CID fragmentation do not allow unambiguous differentiation of some amino acids: leucine from isoleucine (identical molar masses and CID fragmentation) and lysine from glutamine (very similar masses). For this reason, we perform proteomic analyses on a state-of-the-art high-resolution <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?manufacturerItems=52&amp;search=+ZenoTOF+7600"><strong>ZenoTOF 7600</strong></a> (SCIEX), in which the Zeno ion trap and EAD (<i>Electron-Activated Dissociation</i>) technology together make a powerful combination.

This provides a truly unique investigative toolbox for the in-depth interrogation of complex mixtures.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_SYNAPT_XS_High_Resolution_Mass_Spectrometer_2_9179e575a4.jpg" alt="Waters SYNAPT XS High Resolution Mass Spectrometer: During each scan the quadrupole separates co-eluting precursor masses by scanning the mass range, and transiting them in sequence.

As well as ion mobility offering an additional dimension of resolution, multiplying <strong>peak capacity</strong>, and <strong>selectivity of analysis</strong> the measurement of CCS offers additional molecular identifiers. The measured CCS of an ion can be used to help confirm an ion’s identity or investigate its structure. The inclusion of ion mobility significantly increases the extent and confidence with which a scientist can profile complex mixtures and complex molecules – dramatically enhancing sample definition.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_SYNAPT_XS_High_Resolution_Mass_Spectrometer_3_2240bff527.jpg" alt="Waters SYNAPT XS High Resolution Mass Spectrometer: Retention and drift time principle ion mobility enabled data-independent LC-HDMSE analysis (LC-DIA-IM-MS)." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Waters_SYNAPT_XS_High_Resolution_Mass_Spectrometer_3_2240bff527.jpg 204w," sizes="100vw" width="1024" height="784"></p></div></div><div><div><h3><strong>Achieve ultra-confident structural characterization of components</strong></h3><p>Time aligned parallel (TAP) fragmentation is an acquisition mode unique to the T-Wave IMS design.
