The researchers also found that decreasing ATP levels enhances ClpXP (a damage-repairing enzyme)-mediated degradation of some classes of substrates. A specific enzyme may play dual roles in cell health according to a recent study from the University of Massachusetts Amherst. Exploring Cellular Stress Response A team of researchers from the University of Massachusetts Amherst investigated the mysteries surrounding how cells handle stress in a recent study that was published in the journal Cell Reports. Researchers found that a damage-repairing enzyme known as ClpX may not only mutate to fix multiple cellular issues but can also react to shifting levels of cellular energy to maintain cell health. “What we’re really interested in,” says Peter Chien, professor of biochemistry and molecular biology at UMass Amherst and the paper’s senior author, “is how cells respond to stress. We study a class of enzymes, called proteases, which target and destroy harmful proteins within a cell. These proteases can selectively recognize specific, individual proteins singular proteins. But how do they do this? How can they choose between healthy proteins and harmful ones?” Rendering of the protease ClpX: the gray part recognizes the harmful protein, the orange grabs onto it, and the blue destroys it. Credit: Chien Lab Chien and his co-authors focused on two specific proteases, called Lon and ClpX, each of which is finely tuned to recognize a different harmful protein, to answer this question. It had long been believed that Lon and ClpX functioned similarly to keys: each could only open one kind of lock and not another, and if a cell lacked either, severe side effects would result. “If you’ve ever had an extremely messy college roommate,” says Chien, “you know how important it is to empty the trash regularly. Missing the Lon protease is like having a roommate who never washes, changes, or cleans.” Discovery of Protease Flexibility But following a series of experiments in which Lon was removed from bacterial cell colonies, Chien’s team saw something strange: some of the colonies were still alive. Peter Chien (right) and UMass undergraduate researcher Oluwabusola Oreofe (left) running experiments in the Chien lab. Credit: UMass Amherst This observation led to their first discovery: ClpX can mutate to perform a Lon-like function, though it loses some of its ClpX abilities. It’s as if, to keep your dorm room clean, you started washing your roommate’s socks, but had to sacrifice some of your own clean laundry to do so. In tracing out exactly how the ClpX mutation allowed the protease to expand its function, the team made its second discovery: wild, non-mutant ClpX can also perform some of Lon’s duties, under the right conditions. It turns out that ClpX is highly sensitive to ATP, an organic compound that is the energy source for all living cells. At normal levels of ATP, ClpX focuses on its own duties, but at a specific, lower threshold it suddenly starts cleaning up after Lon. “This is a real breakthrough in the basic understanding of how cells work,” says Chien. “It changes the rules: not only does cellular energy control how fast a cell works, but how it works, as well.” Reference: “ATP hydrolysis tunes specificity of a AAA+ protease” by Samar A.

In starved fission yeast, the ribosomes attach to the mitochondrial outer membrane via their small subunit. This is a very unusual ‘upside-down’ orientation. Credit: Isabel Romero Calvo/EMBL Scientists from EMBL Heidelberg and the University of Virginia have uncovered an intriguing mechanism by which cells adapt to starvation, a discovery that could have significant implications for cancer research. What can stressed yeast reveal about fundamental cellular processes? Quite a bit, according to researchers at the European Molecular Biology Laboratory (EMBL). The team studies, among other topics, how cells adapt to stress — such as nutrient deprivation. One of their favorite test subjects is the yeast species S. pombe, for centuries used in traditional brewing. As a eukaryote, it’s in many ways similar to human cells, so biologists often use it as a model organism to study fundamental cellular processes. Ribosomes turn upside-down in hungry cells Scientists have observed that yeast cells have a remarkable adaptation to starvation: their mitochondria get coated by a swarm of massive molecular complexes called ribosomes. Intrigued by this odd phenomenon, the Mattei Team at EMBL Heidelberg and the Jomaa Lab at the University of Virginia School of Medicine explored it in greater detail using single-particle cryo-electron microscopy and cryo-electron tomography. Ribosomes are the cell’s heavyweight molecular machinery that produces proteins. It turned out, however, that in hungry yeast cells, the ribosomes that crowd on the surface of the mitochondria don’t produce anything. They are hibernating. “One way for a cell to survive stressful conditions until better days is to reduce its use of energy to a minimum,” explained Olivier Gemin, EIPOD Postdoctoral Fellow in the Mattei Team who led this new study. “Producing proteins demands a lot of energy, which can be saved by blocking ribosomes.” Why the hibernating ribosomes attach to the surface of mitochondria is a mystery. “There could be different explanations,” said Team Leader Simone Mattei. “A starved cell will eventually start digesting itself, so the ribosomes might be coating the mitochondria to protect them. They might also attach to trigger a signaling cascade inside the mitochondria.” Another possibility that Mattei is investigating relates to the fact that starving cells need a way to quickly start producing energy once food (in the form of glucose) is available again. Since mitochondria are the energy producers of the cell, having ribosomes nearby to produce necessary proteins might help this process along. What made the scientists’ jaws drop was noticing that the ribosomes attach to the mitochondrial outer membrane in a way that contradicts what’s been known about them before. “So far, ribosomes were known to interact with membranes only via their large subunit. But in starved cells, we saw that they do this upside-down, via the small subunit!” said Mattei. In their future studies, the team will investigate how and why the ribosomes attach in such an unusual way. Cancer cells go through the hell they create The struggles of the starved yeast cells have some similarities to those of cancer cells. Believe it or not, being a cancer cell is really tough. When a tumor becomes aggressive, its cells grow so rapidly that their demand for nutrients and oxygen outpaces the supply. This means most cancer cells are constantly starving in a kind of hell they create for themselves. Yet, they survive and even multiply. “That’s why we need to understand the basics of adaptation to starvation and how these cells become dormant to stay alive and avoid death,” said Ahmad Jomaa, Assistant Professor and Group Leader at the University of Virginia’s School of Medicine and a senior co-author of the study. “For that, we use yeast first, because we can manipulate it much more easily. Beyond this, we try to starve cultured cancer cells too, which is not easy, to figure out how they overcome starvation and can sometimes lead to cancer relapse.” Understanding the principles of this adaptation could help us find ways to override it, making cancer cells vulnerable to starvation and thus more susceptible to treatment.

Biologists and paleontologists have long debated the origins of North American porcupines, with DNA suggesting a 10 million year history, while fossils indicate they may have evolved only 2.5 million years ago. A new study, leveraging a nearly complete porcupine skeleton found in Florida, has clarified this timeline by comparing anatomical differences with South American species, concluding North American porcupines are indeed an ancient group. The study, supported by a unique college course, also explored the broader migratory and evolutionary patterns of porcupines and other mammals across continents, highlighting how environmental changes shaped their adaptations and survival. Credit: Florida Museum photo by Jeff Gage New findings from a complete porcupine skeleton in Florida reveal a much earlier origin for North American porcupines, predating the Isthmus of Panama, and suggest a mixed evolutionary lineage with traits of both North and South American species. There’s a longstanding debate simmering among biologists who study porcupines. In Central and South America, there are 16 species of porcupines, while North America has just one. Genetic data indicates that this lone North American porcupine is part of a lineage that dates back 10 million years. However, fossil records provide a contrasting narrative, suggesting that they might have evolved only 2.5 million years ago, at the beginning of the ice ages. A new study published in the journal Current Biology claims to have reconciled the dispute, thanks to an exceptionally rare, nearly complete porcupine skeleton discovered in Florida. The authors reached their conclusion by studying key differences in bone structure between North and South American porcupines, but getting there wasn’t easy. It took an entire class of graduate and undergraduate students and several years of careful preparation and study. “Even for a seasoned curator with all the necessary expertise, it takes an incredible amount of time to fully study and process an entire skeleton,” said lead author Natasha Vitek. While studying as a doctoral student at the Florida Museum of Natural History, Vitek teamed up with vertebrate paleontology curator Jonathan Bloch to create a college course in which students got hands-on research experience by studying porcupine fossils. Ancient radiation gave rise to the world’s largest rodents Porcupines are a type of rodent, and their ancestors likely originated in Africa more than 30 million years ago. Their descendants have since wandered into Asia and parts of Europe by land, but their journey to South America is a particularly defining event in the history of mammals. They crossed the Atlantic Ocean — likely by rafting — when Africa and South America were much closer together than they are today. They were the first rodents to ever set foot on the continent, where they evolved into well-known groups like guinea pigs, chinchillas, capybaras, and porcupines. Some took on giant proportions. There were lumbering, rat-like animals up to five feet long, equipped with a tiny brain that weighed less than a plum. Extinct relatives of the capybara grew to the size of cows. Porcupines remained relatively small and evolved adaptations for life in the treetops of South America’s lush rainforests. Today, they travel through the canopy with the aid of long fingers capped with blunt, sickle-shaped claws perfectly angled for gripping branches. Many also have long, prehensile tails capable of bearing their weight, which they use while climbing and reaching for fruit. North (left) and South (right) American porcupines have been on separate evolutionary trajectories for as long as 10 million years. Credit: Florida Museum photo by Kristen Grace Despite their excellent track record of getting around, South America was a dead end for many millions of years. A vast seaway with swift currents separated North and South America, and most animals were unable to cross — with a few notable exceptions. Beginning about 5 million years ago, the Isthmus of Panama rose above sea level, cutting off the Pacific from the Atlantic. This land bridge became the ancient equivalent of a congested highway a few million years later, with traffic flowing in both directions. Prehistoric elephants, saber-toothed cats, jaguars, llamas, peccaries, deer, skunks, and bears streamed from North America to South. The reverse trek was made by four different kinds of ground sloths, oversized armadillos, terror birds, capybaras, and even a marsupial. The two groups met with radically different fates. Those mammals migrating south did fairly well; many became successfully established in their new tropical environments and survived to the present. But nearly all lineages that ventured north into colder environments have gone extinct. Today, there are only three survivors: the nine-banded armadillo, the Virginia opossum, and the North American porcupine. New fossils catch evolution in the act Animals that traveled north had to contend with new environments that bore little resemblance to the ones they left behind. Warm, tropical forests gave way to open grasslands, deserts, and cold deciduous forests. For porcupines, this meant coping with brutal winters, fewer resources and coming down from the trees to walk on land. They still haven’t quite gotten the hang of the latter; North American porcupines have a maximum ground speed of about 2 mph. South American porcupines are equipped with a menacing coat of hollow, overlapping quills, which offer a substantial amount of protection but do little to regulate body temperature. North American porcupines replaced these with a mix of insulating fur and long, needle-like quills that can be raised when they feel threatened. They also had to modify their diet, which changed the shape of their jaw. “In winter, when their favorite foods are not around, they will bite into tree bark to get at the softer tissue underneath. It’s not great food, but it’s better than nothing,” Vitek said. “We think this type of feeding selected for a particular jaw structure that makes them better at grinding.” They also lost their prehensile tails. Although North American porcupines still like climbing, it’s not their forte. Museum specimens often show evidence of healed bone fractures, likely caused by falling from trees. Many of these traits can be observed in fossils. The problem is there aren’t many fossils to go around. According to Vitek, most are either individual teeth or jaw fragments, and researchers often lump them in with South American porcupines. Those that are considered to belong to the North American group lack the critical features that would provide paleontologists with clues to how they evolved. So when Florida Museum paleontologist Art Poyer found an exquisitely preserved porcupine skeleton in a Florida limestone quarry, they were well aware of its significance. “When they first brought it in, I was amazed,” said Bloch, senior author of the study. “It is so rare to get fossil skeletons like this with not only a skull and jaws, but many associated bones from the rest of the body. It allows for a much more complete picture of how this extinct mammal would have interacted with its environment. Right away we noticed that it was different from modern North American porcupines in having a specialized tail for grasping branches.” By comparing the fossil skeleton with bones from modern porcupines, Bloch and Vitek were confident they could determine its identity. But the amount of work this would require was more than one person could do on their own in a short amount of time. So they co-created a paleontology college course, in which the only assignment for the entire semester was studying porcupine bones. “It’s the kind of thing that could only be taught at a place like the Florida Museum, where you have both collections and enough students to study them,” Vitek said. “We focused on details of the jaw, limbs, feet, and tails. It required a very detailed series of comparisons that you might not even notice on the first pass.” The results were surprising. The fossil lacked the reinforced bark-gnawing jaws and possessed a prehensile tail, making it appear more closely related to South American porcupines. But, Vitek said, other traits bore a stronger similarity to North American porcupines, including the shape of the middle ear bone as well as the shapes of the lower front and back teeth. With all the data combined, analyses consistently provided the same answer. The fossils belonged to an extinct species of North American porcupine, meaning this group has a long history that likely began before the Isthmus of Panama had formed. But questions remain as to how many species once existed in this group or why they went extinct. “One thing that isn’t resolved by our study is whether these extinct species are direct ancestors of the North American porcupine that is alive today,” Vitek said. “It’s also possible porcupines got into temperate regions twice, once along the Gulf Coast and once out west. We’re not there yet.” Reference: “An extinct north American porcupine with a South American tail” by Natasha S. Vitek, Jennifer C. Hoeflich, Isaac Magallanes, Sean M. Moran, Rachel E.
