Cornell University researchers have revealed how a key mechanism in genes is controlled. Researchers found “poised” genes in yeast, preassembled for rapid activation, revealing mechanisms of transcription regulation shared with humans. Cornell University researchers have discovered a crucial mechanism in how genes are controlled through the study of yeast, a simple organism that is necessary for the production of beer and bread. Gene transcription, the complex process through which human cells read genetic information encoded in DNA, was previously believed to be activated only when particular regulatory factors traveled to certain DNA sequences. A group of Cornell scientists found that certain genes already have their transcription regulatory factors and cofactors in place, but they are in a latent state, according to a recent study published in the journal Genes & Development. These “poised” genes become highly active when the appropriate signals arrive. The researchers used CRISPR techniques to delete elements of the yeast transcription machinery in order to comprehensively investigate their role in gene regulation. Because yeast and humans use the same molecular machinery to control their genes, yeast is an excellent model for understanding human gene regulation. “It’s like the game of Jenga, where you remove a wood block from a tower of blocks and see if the whole thing crashes down. That’s how we learn how protein machines work inside cells,” said B. Franklin Pugh ‘83, the Greater Philadelphia Professor of Molecular Biology and Genetics in the College of Arts and Sciences. Two Classes of Genes: Housekeeping and Inducible The researchers identified two classes of yeast genes, based on how they are regulated. The first and largest group provides basic housekeeping functions, allowing the cells to live and grow. These genes are always “on” at very low levels because the transcription machinery has a hard time finding its way to each gene. The second class, the “inducible” genes, has a whole entourage of proteins assembled nearby. When triggered by environmental signals this poised entourage provides a guiding hand to transcription machinery. This results in high levels of induced transcription. “The value of being poised is that certain genes, like environmental response genes, can rapidly respond to a changing environment; for example, when yeast encounters and metabolizes bread sugars, causing the bread dough to rise,” Pugh said. Similar metabolic processes happen in human cells when food is eaten. Pugh has been researching gene regulation for more than 30 years. As a student at Cornell, the idea of how our genes are regulated – so central to biology and so unknown – fascinated him, and he’s spent his life trying to understand it. “With this paper, we finally got to the core question of how do these gene-specific transcription factors that are sensing the environment recruit the core transcription machinery,” he said. “We could not completely answer the question in this paper, but we got solid insight into how that process works.” In previous related work, Pugh mapped precise binding sites of more than 400 different chromosomal proteins in the yeast genome, most of which regulate the expression of genes. “That paper shed significant light on understanding how all these proteins come together and work together to read and regulate genes,” Pugh said. The new research builds on that work, delving deeper into understanding the architectures of proteins and the machinery at genes. “Building upon years of existing research and combining them with modern and elegant genomics tools helped us in filling gaps in the current knowledge as well as in making new discoveries,” said first author Chitvan Mittal, research associate at the Baker Institute for Animal Health in the College of Veterinary Medicine.

A study found that seabream recognize individual divers, following those who feed them while ignoring others. For years, scientific divers at a Mediterranean research station noticed a curious problem — local fish would follow them and steal food meant for experiments. Even more intriguing, the fish seemed to recognize and target specific divers who had fed them before, while ignoring others. To test whether wild fish could truly distinguish between individual humans, researchers from the Max Planck Institute of Animal Behavior (MPI-AB) in Germany conducted a series of experiments. By varying their diving gear, they discovered that fish in the wild can indeed tell people apart using visual cues. Fish Follow Familiar Faces Scientists set out to answer a question that had never been tested in wild fish: can they tell people apart? While some studies have shown that certain captive fish, like archerfish, can recognize human faces in controlled lab settings, there was little evidence that wild fish could do the same. “But nobody has ever asked whether wild fish have the capacity, or indeed motivation, to recognize us when we enter their underwater world,” explains Maëlan Tomasek, a doctoral student at MPI-AB and the University of Clermont Auvergne, France. Now, researchers at MPI-AB have put the question to the test — and the fish have provided a clear answer. Wild fish can indeed recognize individual humans. Even more remarkably, they remember and follow specific divers who have fed them in the past. This discovery, published today (February 18) in Biology Letters, suggests that fish may form distinct relationships with certain humans, challenging assumptions about their cognitive abilities. Wild fish participated as willing volunteers in the study. Many turned up every day to experimental trials, and scientists could recognize some fish by their physical characteristics.

The Fish Who Volunteered The research team conducted the study eight meters underwater at a research site in the Mediterranean Sea where populations of wild fish have become habituated to the presence of scientists. Their experiments took place in open water and fish participated in trials as “willing volunteers who could come and go as they pleased,” explains Katinka Soller, a bachelor student from MPI-AB who was co-first author on the study with Tomasek. The first experimental phase—the training—tested if fish could learn to follow an individual diver. The training diver, Soller, started by trying to attract the attention of local fish; she wore a bright red vest and fed fish while swimming a length of 50 meters. Over time, Soller removed the conspicuous cues until she wore plain dive gear, kept the food hidden, and fed fish only after they had followed her the full 50 meters. Recognizing Their Trainer Of dozens of fish species inhabiting the marine station, two species of seabream in particular willingly engaged in the training sessions. Sea bream are best known to us as fish that we buy to eat, yet they surprised the scientists by their curiosity and willingness to learn. “Once I entered the water, it was a matter of seconds before I would see them swimming towards me, seemingly coming out of nowhere,” says Soller. Not only were bream learning to follow her, but the same individuals were showing up day after day to join the lessons. Soller even took to giving them names: “There was Bernie with two shiny silver scales on the back and Alfie who had a nip out of the tail fin,” she says. After 12 days of training, roughly 20 fish were reliably following Soller on training swims and she could recognize several of them from physical traits. By identifying individual fish participating in the experiment, the stage was set for the next experimental phase: testing if these same fish could tell Soller apart from another diver. The Two-Diver Test This time Soller dived with Tomasek whose dive gear differed slightly from hers, notably in some colorful parts of the wetsuit and fins. Both divers started at the same point and then swam in different directions. On the first day, the fish followed both divers equally. “You could see them struggling to decide who to chase,” says Soller. But Tomasek never fed the fish who followed him, so from the second day, the number of fish following Soller increased significantly. To confirm that fish were learning to recognize the correct diver, the researchers focused on six fish out of the large group to study individually, finding that four of these showed strong positive learning curves over the experiment. “This is a cool result because it shows that fish were not simply following Katinka out of habit or because other fish were there,” says Tomasek. “They were conscious of both divers, testing each one and learning that Katinka produced the reward at the end of the swim.” But when Soller and Tomasek repeated the trials, this time wearing identical diving gear, the fish were unable to discriminate them. For the scientists, this was strong evidence that fish had associated the differences in the dive gear, most likely the colors, with each diver. “Almost all fish have color vision, so it is not surprising that the sea bream learned to associate the correct diver based on patches of color on the body,” says Tomasek. Fish Know How We Look Underwater, we do the same. “Faces are distorted by diving masks, so we usually rely on differences between wetsuits, fins, or other parts of the gear to recognize each other,” says Soller. With more time, the authors say, fish might have learned to pay attention to subtler human features, like hair or hands, to distinguish divers. “We already observed them approaching our faces and scrutinizing our bodies,” adds Soller. “It was like they were studying us, not the other way around.” This study corroborates many anecdotal reports of animals, including fish, recognizing humans; but it goes further by performing dedicated experiments in completely natural contexts. Finding that wild fish can quickly learn to use specific cues to recognize individual human divers, it stands to reason that many other fish species, our pets included, can recognize certain patterns to identify us, the scientists say. This mechanism is the foundation for special interactions between individuals, even across species. A Surprising Bond Across Species Senior author Alex Jordan, who leads a group at MPI-AB, says: “It doesn’t come as a shock to me that these animals, which navigate a complex world and interact with myriad different species every minute, can recognize humans based on visual cues. I suppose the most surprising thing is that we would be surprised that they can. It suggests we might underestimate the capacities of our underwater cousins.” Adds Tomasek: “It might be strange to think about humans sharing a bond with an animal like a fish that sits so far from us on the evolutionary tree, that we don’t intuitively understand. But human-animal relationships can overcome millions of years of evolutionary distance if we bother to pay attention. Now we know that they see us, it’s time for us to see them.” Reference: “Wild fish use visual cues to recognize individual divers” by Maëlan Tomasek, Katinka Soller and Alex Jordan, 1 February 2025, Biology Letters.

Scientists have recently identified a new anatomical structure in the brain called SLYM, an abbreviation of Subarachnoidal LYmphatic-like Membrane, that acts as a barrier and a platform from which immune cells can monitor the brain. The newly discovered SLYM membrane segregates clean and dirty CSF, supporting the brain’s immune defenses and glymphatic system, paving the way for targeted treatments and deeper understanding of brain diseases. The human brain, with its intricacies ranging from neural networks to fundamental biological functions and structures, remains elusive in revealing its secrets. However, recent advancements in neuro-imaging and molecular biology have provided scientists with the ability to study the living brain with unprecedented detail, revealing many previously unknown mysteries. A recent discovery, reported in the journal Science, describes a previously undiscovered component of brain anatomy. This new component serves both as a protective barrier and a base from which immune cells can keep an eye out for any signs of infection or inflammation within the brain. The new study comes from the labs of Maiken Nedergaard, co-director of the Center for Translational Neuromedicine at University of Rochester and the University of Copenhagen and Kjeld Møllgård, M.D., a professor of neuroanatomy at the University of Copenhagen. Nedergaard and her colleagues have transformed our understanding of the fundamental mechanics of the human brain and made significant findings to the field of neuroscience, including detailing the many critical functions of previously overlooked cells in the brain called glia and the brain’s unique process of waste removal, which the lab named the glymphatic system. A newly discovered membrane in the brain called SLYM is a thin but tight barrier that appears to separate “clean” and “dirty” CSF and harbors immune cells. “The discovery of a new anatomic structure that segregates and helps control the flow of cerebrospinal fluid (CSF) in and around the brain now provides us a much greater appreciation of the sophisticated role that CSF plays not only in transporting and removing waste from the brain but also in supporting its immune defenses,” said Nedergaard. The study focuses on the membranes that encase the brain, which create a barrier from the rest of the body, and keeps it bathed in CSF. The traditional understanding of what is collectively called the meningeal layer, a barrier comprised of individual layers known as the dura, arachnoid, and pia matter. Central nervous system immune cells (indicated here expressing CD45) use SLYM as a platform close to the brain’s surface to monitor cerebrospinal fluid for signs of infection and inflammation. Credit: University of Rochester The new layer discovered by the U.S. and Denmark-based research team further divides the space below the arachnoid layer, the subarachnoid space, into two compartments, separated by the newly described layer, which the researchers name the SLYM, an abbreviation of Subarachnoidal LYmphatic-like Membrane. While much of the research in the paper describes the function of SLYM in mice, they also report its actual presence in the adult human brain as well. Structure and Purpose of the SLYM Membrane The SLYM is a type of membrane called mesothelium, which is known to line other organs in the body, including the lungs and heart. Mesothelia typically surround and protect organs, and harbor immune cells. The idea that a similar membrane might exist in the central nervous system was a question first posed by Møllgård, the first author of the study. His research focuses on developmental neurobiology, and on the systems of barriers that protect the brain. The new membrane is very thin and delicate, and consists of only one or a few cells in thickness. Yet the SLYM is a tight barrier, and allows only very small molecules to transit; it seems to separate “clean” and “dirty” CSF. This last observation hints at the likely role played by SLYM in the glymphatic system, which requires a controlled flow and exchange of CSF, allowing the influx of fresh CSF while flushing the toxic proteins associated with Alzheimer’s and other neurological diseases from the central nervous system. This discovery will help researchers more precisely understand the mechanics of the glymphatic system, which was the subject of a recent $13 million grant from the National Institutes of Health’s BRAIN Initiative to the Center for Translational Neuromedicine at the University of Rochester. SLYM and Brain Immune Defense The SLYM also appears important to the brain’s defenses. The central nervous system maintains its own native population of immune cells, and the membrane’s integrity prevents outside immune cells from entering. In addition, the SLYM appears to host its own population of central nervous system immune cells that use the SLYM for surveillance at the surface of brain, allowing them to scan passing CSF for signs of infection. The Discovery of the SLYM opens the door for further study of its role in brain disease. For example, the researchers note that larger and more diverse concentrations of immune cells congregate on the membrane during inflammation and aging. When the membrane was ruptured during traumatic brain injury, the resulting disruption in the flow of CSF impaired the glymphatic system and allowed non-central nervous system immune cells to enter the brain. These and similar observations suggest that diseases as diverse as multiple sclerosis, central nervous system infections, and Alzheimer’s might be triggered or worsened by abnormalities in SLYM function. They also suggest that the delivery of drugs and gene therapeutics to the brain may be impacted by SLYM function, which will need to be considered as new generations of biologic therapies are being developed.
