Fish eyes from stem cells of bony fish
3/09/21 A research team from the Centre for Organismal Studies (COS) has demonstrated that complex retinal tissue can be cultured in a Petri dish from embryonic stem cells of bony fish. Until now, stem cells from mammals, including humans, have been used in organoid research. For the first time, researchers led by Prof. Dr Joachim Wittbrodt have demonstrated that stem cells from medaka and zebrafish can also form highly organised neural structures under controlled laboratory conditions. Among other things, the researchers expect to gain new insights into the basic mechanisms of retinal development. More information here.
Decoding genetic programs responsible for the development of the cerebellum
29/07/21 The mammalian cerebellum has long been associated almost exclusively with motor control, yet recent studies indicate that it also contributes to many higher brain functions. An international research team led by Prof. Dr Henrik Kaessmann from the Center for Molecular Biology of Heidelberg University (ZMBH) has now decoded the genetic programmes that control the development of cerebellar cell types before and after birth. The molecular biologists compared data from the mouse cerebellum with corresponding data from the opossum, revealing fundamental gene regulatory networks that must have already formed in the early stage of mammalian evolution more than 160 million years ago. The study was carried out in close collaboration with Prof. Dr Stefan Pfister of the Hopp Children’s Cancer Center Heidelberg (KiTZ). More information here.
Medaka model developed to study glycosylation defects in vivo
23/06/21 A research team led by Prof. Joachim Wittbrodt and Dr. Thomas Thumberger developed a new genetic model in the japanese rice fish medaka, to study multisystemic phenotypes of hypo-N-glycosylation in vivo. Using CRISPR/Cas9, a gene involved in glycosylation (ALG2) was truncated to mimic an existing genotype from a human patient suffering from CDG (congenital disorder of glycosylation). This led to similar phenotypes which could be rescued by microinjection of full-length alg2 mRNA. More information here (link to paper).
Second round CRC 1324 approved
20/05/21 The research of CRC 1324 focuses on so-called Wnt proteins, which control central processes in embryonic development and cell differentiation as well as in tumorigenesis. These proteins arose very early in the evolution of animals and also play an important role in human diseases. After focusing in particular on mechanisms of Wnt signal transduction in the first funding period, the Heidelberg life science researchers will now turn their attention to transferring the gained knowledge into a spatial and temporal context during organ development and in the development of diseases. Prof. Holstein (image) was the spokesperson of the CRC in the first round, a role which in the second funding period will be taken over by Prof. Boutros from the Medical Faculty Mannheim. The DFG is funding CRC 1324 “Mechanisms and Functions of the Wnt Signaling Pathway” with approximately 11.5 million euros. More Information
Natural functions of APP protein family unravelled
20/05/21 While the APP protein is well-known for its key role in Alzheimer’s disease, its contribution to healthy brain function, by contrast, has remained largely unknown until now. Recently, an international research team, led by Prof. Dr Ulrike Müller from the IPMB, gained new insights on the physiological functions of the APP protein family by using a mouse model lacking APP. The absence of APP during brain development was shown to result in the malformation of important brain regions implicated in learning and memory. Consequently, these mice were severely impaired in their learning abilities and exhibited autistic-like behaviour. More Information
Corals that "spit" algae
05/05/21 Microalgae of the dinoflagellate group are known for their ability to survive in other animal cells. These tiny single-cell organisms have engaged in mutually beneficial relationships with corals since primeval times. By passing on critical nutrients to their hosts, dinoflagellates allow corals to thrive even in barren areas. A research team led by Prof. Guse from the Centre for Organismal Studies (COS) recently discovered that such symbioses within the cell essentially depend on the ability of the algae to suppress the immune system of their host cell and thereby avoid being “spit out” again. At the same time, the researchers found indications that this cellular immune response is an evolutionarily ancient immune mechanism that is more widespread than previously assumed. More Information
ERC Advanced Grant for Henrik Kaessmann
23/04/21 In the project “VerteBrain – The Ancestral Vertebrate Brain and its Cellular Diversification During Evolution” funded by the ERC Advanced Grant, Prof. Kaessmann will study the evolutionary origins of the vertebrate brain. It is the third grant that the European Research Council has awarded him for his research. The two previous projects focused on the evolution of gene expression in adult mammalian organs and the genetic control of organ development in mammals. “Now we will investigate the fundamental question of how the vertebrate brain and its structures originally arose,” he says.

EU Consortium funding for a compact cell-imaging device
14/04/21 How do viral pathogens succeed in penetrating human cells? Which cellular mechanisms do they use to multiply efficiently and, in doing so, how do they change the structure of their host cell? These questions are the focus of a pan-European research project called “Compact Cell-Imaging Device” (CoCID), in which scientists from our Faculty (Dr. Weinhardt, Prof. Bartenschlager) are playing a major role. In order to advance research into viral diseases, the aim of the project is to develop a particularly suitable cell-imaging method – which has so far been of limited access to researchers – for extensive application in medical research.

How ribosomal subunits are formed
18/03/21 Ribosomes are the protein factories of the cell. How they are assembled from subunits is a complicated and multi-layered process being investigated by a research team led by Prof. Dr Ed Hurt from the BZH. Together with colleagues from Ludwig Maximilian University Munich, the researchers have now described the role that a type of molecular “shredder” plays in this process. The research results were published in the journal “Molecular Cell”.
New rice plant variant discovered that largely neutralises arsenic
04/03/21 The agricultural cultivation of the staple food of rice harbours the risk of possible contamination with arsenic that can reach the grains following uptake by the roots. In their investigation of over 4,000 variants of rice, a Chinese-German research team under the direction of Prof. Hell and Dr. Wirtz from the COS discovered a plant variant that resists the toxin. Although the plants thrive in arsenic-contaminated fields, the grains contain far less arsenic than other rice plants. At the same time, this variant has an elevated content of the trace element selenium. More Information
Super-resolution RNA imaging in live cells
01/03/21 Researchers from group of Prof. Jaeschke at the IPMB and cooperation partners at the Karlsruhe Institute of Technology (KIT) have devised a new fluorescence imaging method which enables live-cell RNA imaging with unprecedented resolution. The method is based on a novel molecular marker called Rhodamine-Binding Aptamer for Super-Resolution Imaging Techniques (RhoBAST). This RNA-based fluorescence marker is used in combination with the dye rhodamine. Due to their distinctive properties, marker and dye interact in a very specific way, which makes individual RNA molecules glow. They can then be made visible using single-molecule localisation microscopy (SMLM), a super-resolution imaging technique. More Information
Coronavirus gargling test developed at the ZMBH
22/02/21 Scientists at the ZMBH have developed a simple test to detect the coronavirus. This can also be used for approved on-campus events such as laboratory practicals or on-campus examinations which are strictly necessary for continuing or completing a degree course. This supports measures to prevent the virus and possible mutations from spreading, by detecting asymptomatic carriers of the virus as well as those who have not yet developed symptoms. The aim is to interrupt possible infection chains at an early stage. Teachers can order test kits for the students. The intention is for university staff, too, to be offered the opportunity of a test. More Information

How proteins find their place in the cell
9/12/20 Over a quarter of all proteins in a cell are found in the membrane, where they perform vital functions. To fulfil these roles, membrane proteins must be reliably transported from their site of production in the cell to their destination and correctly inserted into the target membrane. Researchers from the Heidelberg University Biochemistry Center (BZH) in the group of Prof. Sinning have succeeded in determining the three-dimensional structure of a molecular machine responsible for the correct placement of an important membrane protein family – the so-called “tail-anchored” membrane proteins, or TA proteins for short.

Groundbreaking new insights into the regulation and evolution of gene expression in mammalian organs
12/11/20 A large-scale study conducted by molecular biologists from the ZMBH around Prof. Dr. Henrik Kaessmann has yielded groundbreaking new insights into the evolution and regulation of gene expression in mammalian organs. The scientists investigated RNA synthesis and subsequent protein synthesis in the organs of humans and other representative mammals, and with the aid of sequencing technologies, they analysed more than 100 billion gene expression fragments from various organs. They were able to demonstrate that the finely tuned interplay of the two synthesis processes during evolution was crucial for shaping organ functions. The results were published in “Nature”.

Mechanism of amyloid firbil disaggregation unravelled
12/11/20 In many neurodegenerative diseases like Parkinson’s, protein aggregates form in the brain and are assumed to contribute to neuronal cell death. Yet there exists a cellular defence mechanism that counteracts these aggregates, known as amyloid fibrils, and can even dissolve fibrils already formed. This defence mechanism is based on the activity of molecular chaperones, i.e. protein folding helpers, of the heat shock protein 70 family (Hsp70). Molecular biologists from the ZMBH investigated how the Hsp70 system disaggregates amyloid fibrils of the Parkinson-specific protein α-synuclein in a test tube. The research team led by Prof. Dr Bernd Bukau expects their research results to provide new insights into how Parkinson’s disease develops and what might be done to influence it. The results were published in two articles in the journal “Nature”. More Info

New class of highly effective inhibitors protects against neurodegeneration
12/10/20 Neurobiologists at our Faculty have discovered how a special receptor at neuronal junctions that normally activates a protective genetic programme can lead to nerve cell death when located outside synapses. Their fundamental findings on neurodegenerative processes simultaneously led the researchers at the Interdisciplinary Center for Neurosciences (IZN) to a completely new principle for therapeutic agents. In their experiments on mouse models, they discovered a new class of highly effective inhibitors for protecting nerve cells. As Prof. Dr Hilmar Bading points out, this novel class of drugs opens up – for the first time – perspectives to combat currently untreatable diseases of the nervous system. The results of this research were published in “Science”. More information can be found here.
Relationship of morphological variation and biological diversity in plants
29/09/20 Genome duplications play a major role in the development of forms and structures of plant organisms and their changes across long periods of evolution. Biologists from our faculty under the direction of Prof. Dr Marcus Koch made this discovery in their research of the Brassicaceae family. To determine the scope of the different variations over 30 million years, they analysed all 4,000 species of this plant family and investigated at the genus level their morphological diversity with respect to all their characteristic traits. The results of this research were published in the journal “Nature Communications”. More info here

Biodiversity in the agricultural landscape
14/07/20 How does ecological farming influence plant biodiversity in the agricultural landscape? Are there positive effects on the landscape level if, for instance, ecological varieties are raised and fields cultivated sustainably? What is the impact of a fluid transition from conventional to ecological farming? These questions are the focus of the AgroBioDiv research project, which combines the respective expertise of Heidelberg University researchers in biology and political science. In addition to exploring biodiversity, the Heidelberg scientists also strive to investigate how policy and public management can support preserving biological diversity in agriculture. The four-year research project headed by Prof. Dr Marcus Koch (picture) and Prof. Dr Jale Tosun has approximately 400,000 euros in funding from the State of Baden-Württemberg. More Info here.
Protecting the neuronal architecture
12/06/20 Protecting nerve cells from losing their characteristic extensions, the dendrites, can reduce brain damage after a stroke.

The results of this research were published in the journal “Nature Machine Intelligence”. More info here
Young Researcher's award goes to COS postdoc
12/8/19 Philippe Golfier, a postdoc from the BBW ForWerts Graduate Program at Centre for Organismal Studies (COS) at Heidelberg University has received the award of the 'Dr. Alexander and Dr. Rosemarie Bauer Stiftung'. The foundation supports young researchers with 2800 € for a research stay abroad to advance their research and to build an international network.
Philippe Golfier received the award for his work on 'Transcriptional regulation of secondary cell walls in Miscanthus sinensis'. The project aims to understand formation of lignocellulosic biomass in Miscanthus sinensis, a fast growing energy crop, which is considered as renewable resource for the production of bio-based products and energy in the future. The components of the lignocellulosic-rich secondary cell walls are tightly regulated by transcription factors. To gain deeper insight into the regulatory properties of three transcription factors (SND1, SCM1, and MYB103), Philippe Golfier spent three months in Prof. Dr. Yujie Fu's lab at the Beijing Forestry University in Beijing, China.
The results of his research were presented at the Bachelor Graduation Ceremony at Bioquant and subsequently the award was handed to Dr. Golfier by Prof. Thomas Greb, the academic dean of the Faculty of Bioscience (see image here).
Networks of Gene Activity Control Organ Development
25/6/19 Researchers from our faculty have decoded the genetic programmes that control the development of major organs in humans and other selected mammals – rhesus monkeys, mice, rats, rabbits, and opossums – before and after birth. Using next-generation sequencing technologies, the molecular biologists at from the ZMBH from the group of Henrik Kaessmann (image) analysed the brain, heart, liver, kidney, testicles, and ovaries. Their large-scale study demonstrated, among other things, that all the organs studied exhibit fundamental and original gene activity networks that must have originated early on in mammalian evolution more than 200 million years ago. In a second large study, the scientists explored for the first time the developmental roles of a hitherto poorly understood but large category of genes, so-called RNA genes, which produce ribonucleic acids and not proteins, like “normal” genes.

Traffic Jam in the Cell: How Are Proteins Assigned to Specific Transporters?
9/04/19 A fundamental cellular mechanism ensures that proteins are transported to the places they are needed in the cells and vesicles are responsible for that transport. Determining their composition has been difficult up to now, not least because of their short life span. By combining innovative investigative techniques, biochemists at Heidelberg University have succeeded in analysing two of these transport vesicles – the COPI and COPII vesicles – comprehensively for the first time. Dr. Frank Adolf from the group of Prof. Wieland published the results of this research in the journal “Cell Reports”. More info here.

Together with 15 international partners, they just launched their 5-year EU H2020 project "ERGO“ on new testing and screening methods to identify endocrine disrupting chemicals (see https://twitter.com/ERGO_EU). Additionally, they received funding for a 2-year EU tender project to develop study protocols for testing of endocrine disrupting effects in non-mammalian vertebrates or invertebrates to improve the identification of substances disturbing the endocrine system in biotic systems, i.e. regulatory relevant endpoints for environmental hazard assessment.
Bifacial Stem Cells Produce Wood and Bast
22/01/19 So-called bifacial stem cells are responsible for one of the most critical growth processes on Earth – the formation of wood. By alternately developing into wood and bast cells, these stem cells are thus starting points for forming wood as well as generating plant bast fibres. A team of researchers under the direction of Prof. Dr. Thomas Greb, a Heisenberg Professor at our faculty, were recently able to demonstrate this phenomenon using new experimental tools. The scientists from the Centre for Organismal Studies labelled and studied specific types of cells in the growth layer of plants, the cambium. More Info
Sulfate Helps Plants Cope With Water Scarcity
21/12/18 Plants absorb the mineral sulfate from groundwater.

Group leader Dr Michael Raissig and his team are studying how grasses form microscopic “breathing” pores on their leaves. The researchers hope to unravel why the grass family, which includes major food crops like rice, maize and wheat, can exchange gases with the atmosphere so efficiently, thus conserving water in the process. Over the next five years, the “Biology of Stomata” research group will receive funding from the German Research Foundation (DFG) totalling approximately 1.5 million euros. More info here
26/04/2018 The intestine of many organisms must be able to renew itself to recover from environmental insults like bacterial infections. This renewal is made possible by a small number of intestinal stem cells which divide and produce daughter cells throughout their lives. The daughter cells differentiate into highly specialised gut cell types. Prof. Sylvia Erhardt and Dr. Ana García del Arco from the ZMBH have studied these processes in the fruit fly and gained new insights into the role of centromeric proteins that largely regulate cell division. The studies reveal that these proteins also play an important part in cell differentiation and tissue renewal. More information here
16/04/2018 A cleavage product of the Alzheimer's APP protein stimulates nerve cell communication and memory.

Spore "memory" links different stages of the bacterial life cycle
8/03/2018 The phenotypic memory of Bacillus subtilis spores can be visualized by tagging the enzyme alanine-dehydrogenase with a red fluorescent protein. Early forming spores contain higher levels of the enzyme than late forming spores. After the addition of the amino-acid L-alanine the early spores germinate faster and grow out. Bacterial spores store information about the individual growth history of their progenitor cells, thus retaining a "memory" that links the different stages of the bacterial life cycle. This phenomenon was demonstrated in a recent study by an interdisciplinary research team led by Dr Ilka Bischofs at the BioQuant Centre of Heidelberg University. The spore memory could give rise to various adaptive behaviours in microbes. The results of the study were published in the journal "Nature Communications". More Information

Distant Relatives: TOR Protein Regulates Cell Growth in Plants and Animals
27/10/2017 Two such different organisms as plants and humans developed from a common precursor cell. Traces of this over one-billion-year kinship remain anchored in the genetic material of both organisms. An international team of plant researchers led by Dr Markus Wirtz and Prof. Dr Rüdiger Hell of Heidelberg University has looked more closely into one such trace – the TOR protein. In human and animal cells, TOR acts as a signal generator that controls both survival and cell growth. The Heidelberg researchers have now discovered how this protein also functions as a growth regulator in plants. More Info
