The identification and characterization of phytogenic substances with the potential to positively influence the metabolic syndrome is the focus of Clemens Röhrl's research projects. The emphasis is on human cholesterol metabolism and the search for bioactive plants and their specific components that can lower cholesterol levels - especially the unfavourable LDL cholesterol. In addition, Clemens Röhrl is interested in the characterization of bioenhancers that increase the bioavailability of other plant constituents and can thus act synergistically against selected symptoms of metabolic syndrome. Clemens Röhrl cooperates with the Johannes Kepler University Linz (Bioinformatics Institute), the Medical University Vienna (Department for Medical Chemistry) and the ETH Zurich (Institute for Molecular Health Sciences) in his projects.

Research projects

Biosensors are widely used, both in basic research and in applied diagnostics. Especially in the biomedical field, an increased demand for new concepts can be observed. In the proposed project ZELLchip, an innovative and modular cell biochip platform, based on microstructured COP (cyclo-olefin polymere) foils are developed. The cell biochips are used for the analysis of the functional basis of selected MHC (major histocompatibility complex) proteins.
The project ZELLchip is funded by the ‘Dissertationsprogramm der Fachhochschule OÖ 2020’ with the financial support of the province of Upper Austria (Austrian Research Promotion Agency (FFG) grant).

MHC class I clusters
At the surface of mammalian cells, there are non-covalent clusters of major histocompatibility complex (MHC) class I molecules. Our preliminary data suggest that they are dimers of free heavy chains. There is evidence that these clusters play important roles in immunology, neuroscience, and cell biology, but they have been difficult to investigate. We will use a two-hybrid antibody micropattern technique that differentiates the conformational forms of class I to investigate the formation of these clusters, their structure, and their physiological role, and complement this work with single-molecule microscopy, biochemistry, and in silico studies.
This project is realized in collaboration with the group of Dr. Sebastian Springer (Jacobs University Bremen, Germany) within a DFG-FWF Lead Agency grant.

BIOsens beta
Basic research for applied biomedical sensors. BIOsens beta is a TIMed Center activity for proof-of-concept studies in the field of 2D/3D printing of functional polymers, micro- and nanostructuring of substrates, cell biochips for compound screening, etc.
BIOsens beta is funded by the province of Upper Austria as part of the FH Upper Austria Center of Excellence for Technological Innovation in Medicine (TIMed CENTER).

Research projects

Focus is on the development of extracts from different natural materials and vegetable raw materials. It is of great interest to find the ideal conditions for different materials such as fruits and seeds but also blossoms, roots and leaves. The type of extraction has an essential influence on the results achieved. This can be heating under reflux (Soxhlet), maceration or ultrasonic treatment. Additionally, the choice of extracting solvent, time, temperature, and the storage conditions are of importance. The quality of the starting materials also plays a major role e.g. if the material is already dry or still in its native condition, or the degree of aging. The obtained extracts are analyzed and prepared for further in-vitro and in-vivo studies.

Analysis can be performed on an HPLC system equipped with various detectors. Thus the type and concentration of polyphenols can be determined, which are very often secondary plant compounds. With GC-MS it is additionally possible to detect and identify volatile components. Complementary determinations can be carried out photometrically.

Development of customized methods for food and feed bioanalytics
The need for sustainable, healthy food is stronger than ever before. More and more people want to exclude additives in their diet and choose therefore healthy and untreated food. Those are more often affected by spoilage than treated ones. Therefore it is of special importance to identify the cause of spoilage, to characterize it and design strategies to prolong the beginning of decay naturally without stabilizers. We currently deal with the following issues

  • Analysis of spoiling substances in food and feed: Some substances in food/feed tend more to spoilage than others. To prolong the beginning of decay as long as possible, substances have to be identified and a strategy is set up to elongate the durability.
  • Enzyme analytics: Enzymes have a strong positive or negative influence on the stability of food and feed, respectively. Therefore, the enzyme concentration needs to be determined and the destructive enzymes inhibited.
  • Development of functional tests: To be able to predict the durability of food and feed, tests are developed, that are optimized for the corresponding food/feed.

Mold in bakery products
Due to the need to reduce chemical stabilizers in food, bakeries have often the problem of growing mold. I am developing protocols to identify the mold species to be able to design custom strategies to avoid and prevent mold.

In order to investigate the uptake and physiological effects of plant substances on humans, the conditions in the human body will be simulated in vitro.

Improving the bioavailability of nutraceutical products
In vitro cultured human intestinal cells are incubated with plant extracts to investigate how the extraction procedure and the administration (extracts e.g. in micelles, oil or water) influence the uptake in the body. After incubation, the cells are harvested and the proportion of the absorbed extracts is analysed.

Cell protecting effects of nutraceutical products
In addition, methods are established and further developed to determine possible cell-protective properties of plant substances. For this purpose, cells are treated with plant extracts and stressed with pro-inflammatory or oxidative substances in order to identify possible anti-inflammatory and/or antioxidant properties of the extracts.

Development and application of analytical methods (HPLC-UV/VIS, GC-MS) for detection and quantification of phytogenic substances in food additives and cell culture systems.

Improvement of the bioavailability of nutraceutical products

To optimize the absorption and bioavailability of phytogenic substances in food additives and nutraceutical products, analytical methods for the detection and quantification of these substances in cell culture systems are being developed. Main challenges are the chromatographical separation of structurally similar compounds (e.g. the xanthophylls lutein and zeaxanthin) as well as potential metabolism and chemical modification of the substances in vitro (e.g. soy isoflavones). Some substances are absorbed only in minute amounts (e.g. the omega-3 fatty acids DHA and EPA), thus requiring sensitive analytical methods (GC-MS).

Prototype development of an onion extract

To aid in the development of a food additive based on fermented onion extracts, chemical and microbiological analyses are performed. Metabolites are monitored by HPLC-based methodsto optimize fermentation conditions and the antimicrobial activity of the product is assessed by performance of microbial inhibition assays.

Phytochemicals - Molecular bioanalytics of plant extracts

Selected, phytogenic substances are tested in various model-systems (CaCo2, C. elegans, broiler) by using gene expression analysis and cytotoxicity assays in order to evaluate their positive effects. Phytogenic substances are mainly herbs, spices as well as plants and their extracts or essential oils. In the context of antibiotic resistances as well as health problems of farm animals due to global warming, phytogenic substances play (besides pre- and probiotics) a major role in preservation of animal health. The genes of interest are mostly heat shock proteins, inflammation parameters, anti-oxidative enzymes and tight junction markers. Relevant molecular biological methods like sample homogenization, RNA extraction from cell and tissue samples, primer design, quantitative real-time PCR (qPCR) and methods for molecular cell physiology are established as well.

Utilizing C. elegans as model organism

Caenorhabditis elegans is a transparent nematode which is about 1 mm in length. It is utilized as a sensitive and reliable in-vivo high-throughput system for the characterization of phytogenic substances. Different methods like toxicity assays, life-span assays, quantitative real-time PCR (qPCR) or fluorescent gene reporters are currently available. Furthermore, C. elegans is utilized as infection model to identify phytochemicals with antimicrobial properties.

PhytoFERM - fermentation of plant substances to increase their biological activity (PhD grant of the FH OÖ)

Plant-derived bioactive compounds, termed phytochemicals, are used as feed additives to support health of farm animals. To exert any biological effect in the animal, the bioactive ingredients added to feed must pass the intestinal barrier and be available at the site of action. However, glycosylation of phytochemicals often limits their intestinal absorption, thereby reducing beneficial effects on animal health. This PhD project intends to develop a fermentation method for releasing of bioactive plant substances in glycosidic linkages by means of bacterial enzymes. Moreover, molecular and cellular mechanisms affected by fermented and non-fermented substances will be investigated in suitable in-vitro and in-vivo test models. In particluar, the influence on antioxidant and anti-inflammatory effects will be examined. Fermented plant extracts with biological activity could be used as innovative additives in the feed industry.

Drosophila melanogaster as model system for intestinal and cognitive function studies involving phytogenic compounds


Establishment of model organism Drosophila melanogaster

Drosophila melanogaster (D. melanogaster), also commonly known as a fruit fly, is a fly of the Drosophilidae family of about 3-4 mm in size. D. melanogaster will be established as an in vivo model organism for the study of intestinal functions (e.g., absorbance, digestion, intestinal immune defence) and cognitive functions (e.g., memory and learning) in context of phytogenic substances. The fully sequenced genome of D. melanogaster points that ca. 60% of genome is homologous to that of a human and therefore makes this species a valuable in vivo model for various nutrition studies. The relatively short lifespan of the fruit fly (20 to 50 days in average) allows life-long complex studies of the phytogenic compounds and drugs to observe the impact of the tested drugs on the longevity, fertility, and the genetic impact on the next generation of flies.

Establishment of the relevant experiments for the research of phytogenic substance in vivo using D. melanogaster

To study the impact of phytogenic substances on the whole organism lifespan and selected intestinal and cognitive functions, the relevant experiment designs will be established in the laboratory. First, the toxicity of the substances on the developmental processes, as well as toxicity in adult flies will be tested. To define the protective capabilities of the phytogenic drugs the heat shock and oxidative stress assay will be applied, followed up by the mRNA extraction and related gene expression analysis. The optimal dosage of bioactive compounds will be realized via lifespan and bioavailability analysis.

The use of plant based metabolites in areas such as the cosmetics, and food and feed industries has attracted particular attention in recent years. Despite this increasing popularity, little is known about the bioavailability and biological efficacy of these plant metabolites.

Using various in vitro and in vivo models, the uptake and bioavailability of phytogenic substances are quantified and compared by chemical analysis, especially by HPLC. The potential anti-inflammatory and antioxidant effects will be investigated in suitable in vitro and in vivo test systems. Initially, robust assays for the induction and quantification of inflammation will be established and further developed in these models. The expression of inflammatory and antioxidant genes will be analysed by RT-qPCR. The aim is to enable further characterisation of phytogenic substances and to gain new insights for further work in this field.

Analysis of plant-derived compounds on their antioxidant potential and the effects on intestinal barrier functionality in different cell lines.
The level of reactive oxygen species in different cell systems is increased by chemical or thermal stress. The treatment with herbal substances may reduce this oxidative stress. Additionally, these substances are tested in transwell-systems to determine the effects on intestinal barrier. Human and animal intestinal cells are cultivated on membranes and the permeability is measured with reference substances.

Screening of various natural substances with regard to their impact on the gene expression in human and animal cell models
Different cell systems are treated with herbal substances and subsequently the expression levels of certain genes are determined via quantitative RT-PCR. Especially genes involved in antioxidant or anti-inflammatory processes are of high interest. Hence constitutional food- or feed additives are characterized.

Effect of plant-based compounds on the intestinal barrier

The gastrointestinal epithelium represents the largest surface for exchange between the host milieu and the external environment. It facilitates the uptake of essential nutrients and limits the passage of potentially harmful substances. However, the gastrointestinal epithelium is constantly exposed to potent stressors, which may disrupt cell-cell junctions increasing the risk for the acquisition of gastrointestinal diseases. Therefore, the main objective of this project is to identify and characterize novel phytogenic substances/extracts that are effective in improving the intestinal barrier function and stress tolerance using an in vitro trans-well screening system based on different (intestinal) epithelial cell lines.

Bioavailability studies of micronutrients and the effect of phytogenic extracts

To investigate the absorption and bioavailability of micronutrients (vitamins) from nutraceutical products, in vitro test systems based on human intestinal and human buccal epithelial cell lines are established. Furthermore, co-treatment with various phytogenic extracts is tested additionally, as certain plant-derived compounds may act as bioenhancers by improving the absorption rate of (micro-)nutrients.

Identification of substances with regulatory effects on glucose transport through the intestinal barrier

Transport studies using the Caco-2 cell model grown and differentiated on trans-well inserts are carried out to determine the bioavailability of glucose. By using an intestinal cell line, conclusions about the glucose transport in the human intestine can be drawn. Extracts, which have a potentially regulatory influence on glucose transport through the intestinal barrier can be identified and tested for their exact mechanisms of action by means of further molecular biological methods and, if necessary, are verified in-vivo by means of animal experiments and clinical studies.

Phytogenic substances against atherosclerosis

Atherosclerosis is the main cause of cardiovascular or cerebrovascular diseases, two of the most common causes of disease and death worldwide. A therapeutic approach is the intervention in cellular cholesterol and lipoprotein metabolism. Statins, the most frequently utilized cholesterol-lowering drugs on the market, for example, are inhibitors of the rate-limiting enzyme for cholesterol synthesis (HMG-CoA reductase) and thus reduce cellular cholesterol biosynthesis. Phytogenic substances also interfere with these processes. Therefore, they can lead to a reduction of cholesterol, especially the unfavourable LDL-cholesterol in the plasma, thus, reducing the risk of atherosclerosis. Another approach is to find phytogenic substances that counteract the deposition of cholesterol in the arteries. Thus, cell culture studies will be carried out to identify phytogenic substances that have an anti-atherosclerotic effect via these two mechanisms of action.

Sustainable food packaging

The extensive use of conventional plastics in the food packaging industries causes high levels of pollution and the formation of microplastics that can easily enter the food chain, endangering animal and human health.

Bio-based and biodegradable plastics have emerged as a promising alternative to replace fossil-based plastics in many applications, such as food packaging. A careful selection of the packaging material is necessary to ensure that a packed product has the required shelf life. Within the project, the application and characterisation of novel packaging materials made from sustainable raw materials and their functionalisation are researched in order to provide protection against microbial and oxidative spoilage in addition to the primary protective functions.

FAFA – fermented algae extract as feed additives

Due to their antioxidant and anti-inflammatory activity and prebiotic effects, natural molecules from plants and from marine algae (seaweeds) are used as feed additives to improve performance and health of animals. However, these phenolic compounds are present in plants in the form of esters, glycosides, or polymers, resulting in limited bioactivity in the animals. The aim of this project is to increase the bioavailability and bioactivity of phenolic compounds by biotransformation while maintaining their stability in the feed. Substrate bioactivity of bio-transformed and non-bio-transformed substances will be investigated in in-vitro and in-vivo models. Moreover, new molecules from plants and algae that have promise to advance toward feed application will be evaluated.

Identification of novel bioenhancers

Various nature-derived compounds and extracts display promising health-promoting effects in cell culture studies. However, their application is frequently limited by low bioavailability. Compounds that increase the bioavailability of other substances are referred to as bioenhancers and enable synergistic application for human and animal health. Within this project we aim to identify novel bioenhancers by means of combining in-silico bioinformatics analyses with methods of biochemistry, molecular and cell biology.

Natural products against metabolic disorders

Naturally occurring compounds can counteract symptoms of metabolic syndrome such as hypercholesterolemia, fatty-liver disease or cancer. In particular, various plant-derived substances act beneficially even on top of lifestyle modification or pharmaceutical intervention. We aim to identify and characterize novel natural compounds and extracts to ameliorate hypercholesterolemia and fatty liver disease. Therefore, high-content screening methods are combined with stringent validation and mechanistic studies on cell biological effects.

Bioavailability studies to improve nutrient resorption

Focus is on the development of analytical methods for the detection and quantification of micronutrients, for example vitamins. Their resorption and bioavailability should be optimized and investigated in cell culture systems. Analysis is carried out using liquid chromatography coupled to mass spectrometry, UV/Vis detection or refractive index detection.

Furthermore, the aim is to isolate and purify phytogenic substances and active components for subsequent characterization in in-vitro and in-vivo tests. Therefore, the transition from the analytical scale to the preparative scale is necessary, which is realized by a preparative high performance liquid chromatography.

Most infectious diseases are caused by bacteria which proliferate within quorum sensing (QS) mediated biofilms. QS is a cell-cell communication process in which bacteria use the production and detection of extracellular chemicals called autoinducers to monitor cell population density. Further, bacterial behavior within biofilms is regulated by QS through expression of virulence genes in a cell density dependent manner. Efforts to disrupt biofilms have enabled the identification of molecules with abilities to quench the QS system. The process of QS can be disrupted by different mechanisms like reducing or inhibiting the activity of signal molecules. Such findings are likely to lead to efficient treatments with much lower doses of drugs especially antibiotics than required at present. This is of special interest as the excessive use of antibiotics to treat bacterial infections has lead to the emergence of multiple drug resistant strains.
Within the project, we focus on the detection of QS activity by measuring the expression of downstream targets by qPCR and the detection of autoinducers by bioluminescence assay and HPLC.

Development of a plant extract 

Consumers demand from the food industry natural and high-quality products with a long shelf life. Most processed foods are currently preserved by the addition of chemical preservatives. More and more people want to eat sustainably and therefore avoid food with preservatives. Therefore, the aim is to replace artificial additives in processed foods (finished products) with natural extracts. Natural ingredients such as polyphenols are responsible for the preservative and antibacterial effect of such extracts.

Identification of microorganisms 

Another research project is the development of strategies for the identification of microorganisms based on their DNA.

Development of optimized substrates for the production of oyster mushrooms 

Vegetable raw materials are becoming increasingly important for the production of meat substitutes. Some edible mushrooms are particularly suitable as meat substitutes due to their meat-like structure. In order to increase the yield, the substrate must be adapted to the optimal growth conditions of the fungi. Strategies for alternative use/utilisation of the harvested substrate blocks are also of essential importance.
