A new study shows that gut bacteria can influence the molecular pattern of glycosylation – the presence of sugar groups on proteins – in the brain. Credit: Daniela Velasco Lozano/EMBL By employing a novel technique to examine how carbohydrates modify proteins, scientists have found that gut bacteria can influence molecular signatures in the brain. Our gut is home to trillions of bacteria, which play a crucial role in our health and disease. A recent study by researchers at EMBL Heidelberg reveals that these gut bacteria can trigger significant molecular changes in one of our most vital organs—the brain. Published in Nature Structural & Molecular Biology, the study is the first to demonstrate that gut bacteria can influence how proteins in the brain undergo glycosylation, a process in which carbohydrates modify proteins. This breakthrough was made possible by a newly developed method called DQGlyco, which enables researchers to analyze glycosylation with greater scale and precision than ever before. A new way to measure glycosylation Proteins are the workhorses of our cells and their main building blocks. Sugars, or carbohydrates, on the other hand, are among the body’s main sources of energy. However, the cell also uses sugars to chemically modify proteins, altering their functions. This is called glycosylation. “Glycosylation can affect how cells attach to each other (adhesion), how they move (motility), and even how they talk to one another (communication),” explained Clément Potel, first author of the study and Savitski Team Research Scientist. “It is involved in the pathogenesis of several diseases, including cancer and neuronal disorders.” However, glycosylation has traditionally been notoriously difficult to study. Only a small portion of proteins in the cell are glycosylated and concentrating enough of them in a sample for studying (a process called ‘enriching’) tends to be laborious, expensive, and time-consuming.  “So far, it’s not been possible to do such studies on a systematic scale, in a quantitative fashion, and with high reproducibility,” said Mikhail Savitski, Team Leader, Senior Scientist, and Head of the Proteomics Core Facility at EMBL Heidelberg. “These are the challenges we managed to overcome with the new method.”  DQGlyco uses easily available and low-cost laboratory materials, such as functionalised silica beads, to selectively enrich glycosylated proteins from biological samples, which can then be precisely identified and measured. Applying the method to brain tissue samples from mice, the researchers could identify over 150,000 glycosylated forms of proteins (‘proteoforms’), an increase of over 25-fold compared to previous studies. The quantitative nature of the new method means that researchers can compare and measure differences between samples from different tissues, cell lines, species etc. This also allows them to study the pattern of ‘microheterogeneity’ – the phenomenon where the same part of a protein can be modified by many (sometimes hundreds of) different sugar groups.  One of the most common examples of microheterogeneity is human blood groups, where the presence of different sugar groups on proteins in red blood cells determines blood type (A, B, O, and AB). This plays a major role in deciding the success of blood transfusions from one individual to the other.  The new method allowed the team to identify such microheterogeneity across hundreds of protein sites. “I think the widespread prevalence of microheterogeneity is something people had always assumed but that had never been clearly demonstrated, since you need to have enough coverage of glycosylated proteins to be able to make the statement,” said Mira Burtscher, another first author of the study and a Savitski Team PhD student. From the gut to the brain Given the method’s precision and power, the researchers decided to use it to address an outstanding biological question. In collaboration with Michael Zimmermann’s group at EMBL, they next tested whether the gut microbiome had any effect on the glycosylation signatures they had observed in the brain. Both Zimmermann and Savitski are part of the Microbial Ecosystems Transversal Theme at EMBL, which was introduced by the 2022-26 EMBL program ‘Molecules to Ecosystems’.  “It is known that gut microbiomes can affect neural functions, but the molecular details are largely unknown,” said Potel. “Glycosylation is implicated in many processes, such as neurotransmission and axon guidance, so we wanted to test if this was a mechanism by which gut bacteria influenced molecular pathways in the brain.” Interestingly, the team found that when compared to ‘germ-free mice,’ i.e. mice grown in a sterile environment such that they completely lack any microbes in and on their body, mice colonized with different gut bacteria had different glycosylation patterns in the brain. The changed patterns were particularly apparent in proteins known to be important in neural functions, such as cognitive processing and axon growth.  The study’s datasets are openly available via a new dedicated app for other researchers. In addition, the team is also curious whether the data can be used to inform predictions about glycosylation sites, especially in different species. For this, they have been using machine learning approaches such as AlphaFold – the AI-based tool for predicting protein structures recognized with the 2024 Nobel Prize in Chemistry.   “By training the models on mouse data, we can start predicting what could be the variability of glycosylation sites in humans, for example,” said Martin Garrido, a postdoc in the Savitski and Saez-Rodriguez groups at EMBL and another first author of the study. “It could be very useful for people studying other organisms to help them identify glycosylation sites in their proteins of interest.” The researchers are also working towards applying the new method to answer more fundamental biological questions and to understand the functional role glycosylation plays in cells.  Reference: “Uncovering protein glycosylation dynamics and heterogeneity using deep quantitative glycoprofiling (DQGlyco)” by Clément M.

Scientists examined how alterations in the DNA replication timing program affect the packing of DNA with its regulatory factors. Over the last 60 years, scientists have been able to observe how and when genetic information was replicated, determining the existence of a “replication timing program,” a process that controls when and in what order segments of DNA replicate. However, scientists still cannot explain why such a specific timing sequence exists. In a study published on April 23, 2021, in Science, Dr. David Gilbert and his team have answered this 60-year-old question. Dr. David Gilbert, Lead Scientist. Credit: David Gilbert “Why would cells care about the order in which they replicate DNA?” asked lead scientist Dr. Gilbert. “After all – all cells need to replicate all their DNA. Our hypothesis has been that it’s not just DNA that replicates, but all of the regulatory molecules that read the DNA replicate as well.” Dr. Gilbert further hypothesized that there might be a purpose behind the replication timing program and process because “Mother Nature would not squander this opportunity to control how the DNA is read.” “The time at which you replicate provides an ideal time at which to choose whether to maintain all the regulatory factors and continue with the same functional interpretation of the information in DNA or change it to elicit new functions,” explains Dr. Gilbert. Over the last 13 years, Dr. Gilbert and his team showed that each type of cell had a unique replication timing program and that diseased cells had distinct alterations in the program. In this study, Dr. Gilbert and his team looked at how changes in the replication timing program impact the packing of DNA with its regulatory factors, collectively known as the epigenome. The epigenome are regulatory factors that are believed to control the “identity” of the cell, and the functions that the cell will perform. Peiyao A. Zhao, Lead Author of Paper. Credit: Peiyao A. Zhao By eliminating a protein called RIF1, that helps to regulate DNA replication, they found that the replication program was severely and sometimes, almost completely gone so that all segments of chromosomes were replicating at different times in different cells. Without RIF1, if cells were prevented from replicating DNA, their epigenomes were fine. However, as soon as the DNA started to replicate, the regulatory molecules that associate with the DNA became incorporated incorrectly and worsened with each round of DNA replication. Eventually, the 3-dimensional folding of the chromosomes was also altered. Dr. Gilbert suggests that when the epigenome is disrupted by altering the replication timing program, the cells might no longer perform their normal functions, or they may perform inappropriate functions. These inappropriate functions may have a large and negative impact on a person’s health. “We and others have shown previously that the program is altered in many diseases,” says Dr. Gilbert. “Our lab recently showed specific patterns of altered timing that were linked statistically to poor outcomes in pediatric leukemia, and in another study to diseases of premature aging.” Kyle N. Klein. Credit: Kyle N. Klein Thus, the replication timing program provides a whole new genre of molecular pathways and biomarkers that lead to and identify disease states. This could lead to earlier diagnoses and more accurate prognoses for patients. While Dr. Gilbert’s work has answered one important question, he does not plan to stop here. “We think that the epigenome… is not [only] essential for a cell to just maintain its identity, but we hypothesize that it is critical for cells to turn into other cell types.” Testing this hypothesis is crucial for the fields of stem cell research and the therapeutic application of stem cells. Dr. Gilbert is currently using human stem cells to test how a disrupted replication timing affects development of these cells into liver cells, heart cells, and neurons. The results from this study will provide valuable information for human health and disease studies in the future.

Attractive food smells are enough to blunt the life-extending effect of a restricted diet. A research team figured out why this is the case and whether the phenomenon could be blocked with a drug. The smell of food blocks the life-extending effect of a restricted diet. These drugs may unblock it. A research study using worms provides new clues about the role of serotonin and dopamine in aging. It’s common knowledge that a healthy diet is essential to a healthy life. And while many people follow specialized diets to trim down or improve their overall health, scientists interested in aging have been actively studying the life-extending effects of dietary restriction and fasting. “There’s a concept called hormesis in biology, the idea of which is what doesn’t kill you makes you stronger,” said Scott Leiser, Ph.D., an assistant professor in Molecular & Integrative Physiology, and Internal Medicine at University of Michigan Medical School. “One of the stresses that’s been most studied is dietary restriction, shown in many different organisms to extend lifespan and in people to improve health.” Related Anti-Aging Vitamins and Nutrients That Actually Work Cutting Calories and Eating at the Right Time of Day Leads to a Longer Life Potential Supplement for Longer Human Lifespans Adding a Particular Seafood to Your Diet Can Reverse Signs of Aging However, as anyone on a strict weight loss regimen can attest, the mere smell of delicious food can be enough to break one’s willpower. What’s more, previous research actually found that in fruit flies, attractive food smells are enough to blunt the life-extending effect of a restricted diet. That study was from Leiser’s colleague Scott Pletcher, Ph.D., also of the Department of Molecular & Integrative Physiology. Investigating the fmo-2 Gene in Lifespan Extension In a new study published on June 7, 2022, in Nature Communications, Leiser, first authors Hillary Miller, Ph.D., and Shijiao Huang, Ph.D., and their team build on that research to figure out why this is the case and whether a drug could block the phenomenon. In the roundworm C. elegans, lifespan extension in response to environmental stressors such as dietary restriction involves the activation of the fmo-2 gene. The researchers used the transparent nature of C. elegans to be able to see, in real time, the levels of FMO proteins. When worms were limited in the amount of food they could eat, the FMO protein, which was highlighted using a fluorescent marker, lit up “like a Christmas tree…it was bright red,” noted Leiser. However, when the worms were exposed to food smells, there was considerably less activation of FMO, leading to a loss of life extension. One of the main issues of dietary restriction as a potential approach for life extension in people is how difficult it is. But, said Leiser, “what if you could give yourself a drug that confused your body into thinking you were restricting your diet?” Drug Compounds That Mimic Dietary Restriction Building on earlier research showing that neurotransmitters regulate longevity resulting from dietary restriction, the team screened compounds known to act on neurons. They found three compounds that could prevent the reversal of fmo-2 induction in the presence of food: an antidepressant that blocks the neurotransmitter serotonin, and two antipsychotic drugs used to treat schizophrenia, both of which block the neurotransmitter dopamine. “We know serotonin and dopamine are major players in the reward portion of the brain and tend to be involved in satiety and food response signals,” said Leiser. “The fact that the drugs we found were antagonizing this suggests you are blocking aspects of these pathways.” Ultimately, the drugs enabled the life extension effect of FMO, even in the presence of the smell of food. These specific drugs are unlikely to be prescribed for this effect however, given their many potentially dangerous side effects. But they provide important clues about the fmo-2 activation pathway and its effect on life extension.
