Researchers in Frankfurt and Jena have now deciphered how the disturbed recycling chain of the endoplasmic reticulum can cause neurodegenerative diseases. Credit: Manja Schiefer for Jena University Hospital Researchers Have Discovered the Mechanisms That Regulate the Structure and Function of the Endoplasmic Reticulum The endoplasmic reticulum, often abbreviated as ER, is a complex network of tubes, sacs, and membrane-bound compartments that pervade the cells of humans, animals, plants, and fungi. It serves as the manufacturing hub for proteins, overseeing their production, ensuring they fold into the appropriate three-dimensional structure, and modifying them as needed. Additionally, the ER is integral to the production of lipids and hormones, and is responsible for maintaining the cell’s calcium balance. In addition, the ER serves as the foundation for the cell’s transport system, facilitating the movement of materials within the cellular environment. It also plays a key role in quality control by directing misfolded proteins toward the cell’s internal waste disposal system. Furthermore, it neutralizes harmful toxins that find their way into the cell, thus safeguarding the cell’s functionality and health. In view of its multiple tasks, the ER is constantly being remodeled. A process called ER-phagy (roughly “self-digestion of the ER”) is responsible for ER degradation. Involved is a group of signal-receiving proteins – receptors – that are responsible for the membrane curvatures of the ER and thus for its multiple forms in the cell. ER-Phagy and the Role of Ubiquitin in Protein Clustering In ER-phagy, the receptors accumulate at specific sites on the ER and increase membrane curvature to such an extent that, as a consequence, part of the ER is strangulated and broken down into its component parts by cellular recycling structures (autophagosomes). A super-high resolution microscopy technique reveals how FAM134B proteins assemble into clusters after stimulation of ER-phagy in the endoplasmic reticulum. Credit: Gonzáles et al., Nature (2023) How Ubiquitin Enhances ER-Phagy Through FAM134B In cell culture experiments, biochemical and molecular biological studies, and computer simulations, the scientific team led by Professor Ivan Đikić of Goethe University Frankfurt first tested the membrane curvature receptor FAM134B and demonstrated that ubiquitin promotes and stabilizes the formation of clusters of FAM134B protein in the ER membrane. Thus, ubiquitin drives ER-phagy. Đikić explains: “Ubiquitin causes the FAM134B clusters to become more stable and the ER to bulge out more at these sites. The stronger membrane curvature then leads to further stabilization of the clusters and, moreover, attracts additional membrane curvature proteins. So the effect of ubiquitin is self-reinforcing.” The researchers were also able to detect cluster formation using super-high-resolution microscopy. Đikić continues: “To fulfill this function, ubiquitin changes the shape of part of the FAM134B protein. This is another facet of ubiquitin that performs an almost unbelievable array of tasks to keep all different cell functions working.” The importance of ER-phagy is demonstrated by diseases resulting from a defective FAM134B protein. A team led by Professor Christian Hübner from Jena University Hospital previously identified mutations in the FAM134B gene causing a very rare hereditary sensory and autonomic neuropathy (HSAN), in which sensory nerves die. As a result, patients are unable to perceive pain and temperature correctly, which can lead to incorrect stresses or injuries going unnoticed and developing into chronic wounds. In a long-standing collaboration between Jena University Hospital and Goethe University Frankfurt FAM134B was identified as the first receptor for ER-phagy. ARL6IP1 and Its Role in Neurodegeneration Mutations in another membrane curvature protein called ARL6IP1 cause a similar neurodegenerative disorder which combines sensory defects with muscle hardening (spasticity) in the legs. The scientific team led by Christian Hübner and Ivan Đikić has now identified that ARL6IP1 belongs to the ER-phagy machinery as well and is also ubiquitinated during ER-phagy. Christian Hübner explains: “In mice that do not possess the ARL6IP1 protein, we can see that the ER virtually expands and degenerates as the cells age. This leads to an accumulation of misfolded proteins or protein clumps, which are no longer disposed of in the cell. As a result, nerve cells in particular, which do not renew as quickly as other body cells, die, causing the clinical symptoms in affected patients and genetically modified mice. We hypothesize from our data that the two membrane curvature receptors FAM134B and ARL6IP1 form mixed clusters during ER-phagy and depend on each other to control normal size and function of ER. Additional work will be required to fully acknowledge the role of ER-phagy in neurons as well as in other cell types.” Overall, however, the research teams have taken a decisive step toward understanding ER-phagy, Đikić is convinced: “We now understand better how cells control their functions and thus create something we call cellular homeostasis. In biology, this knowledge allows fascinating insights into the incredible achievements of our cells, and for medicine it is essential for understanding diseases, diagnosing them on time, and helping patients by developing new therapies.” References: “Ubiquitination regulates ER-phagy and remodeling of endoplasmic reticulum” by Alexis González, Adriana Covarrubias-Pinto, Ramachandra M.

Can DNA-nanoparticle motors get up to speed with motor proteins? Credit: Illustration by Takanori Harashima Researchers leverage their understanding of molecular motors to improve nanoscale artificial motors, aiming to bridge the speed gap between artificial motors and motor proteins. DNA-nanoparticle motors are exactly what they sound like: tiny artificial motors that harness the structures of DNA and RNA to generate motion through enzymatic RNA degradation. In simple terms, they convert chemical energy into mechanical motion by biasing Brownian motion. These motors operate via a mechanism known as the “burnt-bridge” Brownian ratchet. In this process, the motor moves forward as it “burns” the molecular bonds (or “bridges”) it encounters along its substrate. This degradation biases the random motion, effectively propelling the motor in one direction. DNA-nanoparticle motors are highly programmable and have potential applications in molecular computation, diagnostics, and targeted transport. However, they lack the speed and efficiency of their natural counterparts, motor proteins, which presents a significant challenge. This is where researchers come in to analyze, optimize, and rebuild a faster artificial motor using single-particle tracking experiment and geometry-based kinetic simulation. The Speed Bottleneck “Natural motor proteins play essential roles in biological processes, with a speed of 10-1000　nm/s. Until now, artificial molecular motors have struggled to approach these speeds, with most conventional designs achieving less than 1 nm/s,” said Takanori Harashima, researcher and first author of the study. Researchers published their work in Nature Communications on January 16th, 2025, featuring a proposed solution to the most pressing issue of speed: switching the bottleneck. The experiment and simulation revealed that the binding of RNase H is the bottleneck in which the entire process is slowed. RNase H is an enzyme involved in genome maintenance and breaks down RNA in RNA/DNA hybrids in the motor. The slower RNase H binding occurs, the longer the pauses in motion, which is what leads to a slower overall processing time. By increasing the concentration of RNase H, the speed was markedly improved, showing a decrease in pause lengths from 70 seconds to around 0.2 seconds. However, increasing motor speed came at the cost of processivity (the number of steps before detachment) and run-length (the distance the motor travels before detachment). Researchers found that this trade-off between speed and processivity/run-length could be improved by a larger DNA/RNA hybridization rate, bringing the simulated performance closer to that of a motor protein. Trade-Offs and Optimizations The engineered motor, with redesigned DNA/RNA sequences and a 3.8-fold increase in hybridization rate, achieved a speed of 30 nm/s, 200 processivity, and a 3 μm run-length. These results demonstrate that the DNA-nanoparticle motor is now comparable to a motor protein in performance. “Ultimately, we aim to develop artificial molecular motors that surpass natural motor proteins in performance,” said Harashima. These artificial motors can be very useful in molecular computations based on the motion of the motor, not to mention their merit in the diagnosis of infections or disease-related molecules with a high sensitivity. The experiment and simulation done in this study provide an encouraging outlook for the future of DNA-nanoparticle and related artificial motors and their ability to measure up to motor proteins as well as their applications in nanotechnology.

The research group analyzed the ancient DNA extracted from 50,000-year-old sedimentary feces (the oldest sample of fecal material available to date). The samples were collected in El Salt (Spain), a site where many Neanderthals lived. Credit: University of Bologna Ancient Neanderthal microbes show shared gut health roots with modern humans. Neanderthals’ gut microbiota already included some beneficial micro-organisms that are also found in our own intestines. An international research group led by the University of Bologna achieved this result by extracting and analyzing ancient DNA from 50,000-year-old fecal sediments sampled at the archaeological site of El Salt, near Alicante (Spain). Published in Communication Biology, their paper puts forward the hypothesis of the existence of ancestral components of human microbiota that have been living in the human gastrointestinal tract since before the separation between the Homo Sapiens and Neanderthals that occurred more than 700,000 years ago. “These results allow us to understand which components of the human gut microbiota are essential for our health, as they are integral elements of our biology also from an evolutionary point of view” explains Marco Candela, the professor of the Department of Pharmacy and Biotechnology of the University of Bologna, who coordinated the study. “Nowadays there is a progressive reduction of our microbiota diversity due to the context of our modern life: this research group’s findings could guide us in devising diet- and lifestyle-tailored solutions to counteract this phenomenon.” The Issues of the “Modern” Microbiota The gut microbiota is the collection of trillions of symbiont micro-organisms that populate our gastrointestinal tract. It represents an essential component of our biology and carries out important functions in our bodies, such as regulating our metabolism and immune system and protecting us from pathogenic micro-organisms. Recent studies have shown how some features of modernity — such as the consumption of processed food, drug use, life in hyper-sanitized environments — lead to a critical reduction of biodiversity in the gut microbiota. This depletion is mainly due to the loss of a set of microorganisms referred to as “old friends.” “The process of depletion of the gut microbiota in modern western urban populations could represent a significant wake-up call,” says Simone Rampelli, who is a researcher at the University of Bologna and first author of the study. “This depletion process would become particularly alarming if it involved the loss of those microbiota components that are crucial to our physiology.” Indeed, there are some alarming signs. For example, in the West, we are witnessing a dramatic increase in cases of chronic inflammatory diseases, such as inflammatory bowel disease, metabolic syndrome, type 2 diabetes, and colorectal cancer. How the “Ancient” Microbiota Can Help How can we identify the components of the gut microbiota that are more important for our health? And how can we protect them with targeted solutions? This was the starting point behind the idea of identifying the ancestral traits of our microbiota — i.e. the core of the human gut microbiota, which has remained consistent throughout our evolutionary history. Technology nowadays allows to successfully rise to this challenge thanks to a new scientific field, paleomicrobiology, which studies ancient microorganisms from archaeological remains through DNA sequencing. The research group analyzed ancient DNA samples collected in El Salt (Spain), a site where many Neanderthals lived. To be more precise, they analyzed the ancient DNA extracted from 50,000-year-old sedimentary feces (the oldest sample of fecal material available to date). In this way, they managed to piece together the composition of the micro-organisms populating the intestine of Neanderthals. By comparing the composition of the Neanderthals’ microbiota to ours, many similarities arose. “Through the analysis of ancient DNA, we were able to isolate a core of microorganisms shared with modern Homo sapiens,” explains Silvia Turroni, researcher at the University of Bologna and first author of the study. “This finding allows us to state that these ancient micro-organisms populated the intestine of our species before the separation between Sapiens and Neanderthals, which occurred about 700,000 years ago.” Safeguarding the Microbiota These ancestral components of the human gut microbiota include many well-known bacteria (among which Blautia, Dorea, Roseburia, Ruminococcus, and Faecalibacterium) that are fundamental to our health. Indeed, by producing short-chain fatty acids from dietary fiber, these bacteria regulate our metabolic and immune balance. There is also the Bifidobacterium: a microorganism playing a key role in regulating our immune defenses, especially in early childhood. Finally, in the Neanderthal gut microbiota, researchers identified some of those “old friends.” This confirms the researchers’ hypotheses about the ancestral nature of these components and their recent depletion in the human gut microbiota due to our modern life context. “In the current modernization scenario, in which there is a progressive reduction of microbiota diversity, this information could guide integrated diet- and lifestyle-tailored strategies to safeguard the micro-organisms that are fundamental to our health,” concludes Candela. “To this end, promoting lifestyles that are sustainable for our gut microbiota is of the utmost importance, as it will help maintain the configurations that are compatible with our biology.” Reference: “Components of a Neanderthal gut microbiome recovered from fecal sediments from El Salt” by Simone Rampelli, Silvia Turroni, Carolina Mallol, Cristo Hernandez, Bertila Galván, Ainara Sistiaga, Elena Biagi, Annalisa Astolfi, Patrizia Brigidi, Stefano Benazzi, Cecil M.
