Researchers have uncovered significant diversity in the TAS1R gene family, responsible for taste perception in vertebrates. This discovery, derived from a genome-wide survey, sheds light on the evolutionary history of taste receptors and has potential applications in developing specialized foods for various animal species. A genome-wide survey has uncovered substantial diversity in the evolution of taste receptors across vertebrates. Taste perception is a critical sense, playing a key role in distinguishing nourishing foods from potential toxins. This is exemplified in our preference for sweet and savory flavors, which aligns with the body’s requirements for carbohydrates and proteins. Due to its evolutionary significance, scientists globally are exploring the origins and development of taste receptors through time. Understanding these aspects of feeding behavior in various organisms contributes to a broader understanding of life’s history on our planet. One of the important tastes in our taste palette is umami, or the savory taste, which is associated with proteins that form a vital part of the diets of many organisms. The taste receptor type 1 (T1R) detects sweet and umami tastes among mammals. This taste receptor is encoded by the TAS1R, a family of genes, including TAS1R1, TAS1R2, and TAS1R3, and comes from a common ancestor of bony vertebrates. However, this gene pattern is not observed in coelacanth and cartilaginous fishes, where ‘taxonomically unplaced’ TAS1R genes have been identified, suggesting an incomplete understanding of the evolutionary history of taste receptors. Discovery of New TAS1R Groups Now, however, a research team led by Associate Professor Hidenori Nishihara from Kindai University and Professor Yoshiro Ishimaru from Meiji University, Japan, have identified five new, previously undiscovered groups within the TAS1R family. This discovery is a result of a genome-wide survey of jawed vertebrates including all major fish groups. A new study led by researchers from Kindai University identified five new groups of umami and sweet taste receptors within the TAS1R family (TAS1R 4, 5, 6, 7, and 8) and also diversity in TAS1R2 and TAS1R3 genes. Credit: Hidenori Nishihara from Kindai University The study was published in Nature Ecology & Evolution on December 13, 2023 and included the contributions of Senior Assistant Professor Yasuka Toda from Meiji University, Professor Masataka Okabe from The Jikei University School of Medicine, Professor Shigehiro Kuraku from the National Institute of Genetics, and Project Associate Professor Shinji Okada from The University of Tokyo. “Our study revealed that as compared to most modern vertebrates, the vertebrate ancestor possessed more T1Rs. These findings challenge the paradigm that only three T1R family members have been retained during evolution,” says Prof. Nishihara. The novel taste receptor genes, named TAS1R4, TAS1R5, TAS1R6, TAS1R7, and TAS1R8 by the researchers, were categorized based on their distribution among species with a common ancestor. The researchers found TAS1R4 genes to be present in lizards, axolotl, lungfishes, coelacanth, bichir, and cartilaginous fishes, but absent in mammals, birds, crocodilians, turtles, and teleost fishes. The color key indicates the names of the various T1R members. Filled, colored circles on the branches indicate the presence of the TAS1R members, whereas open circles indicate their absence. Arrowheads above open circles indicate that the TAS1R member was lost at the branch. Credit: Hidenori Nishihara from Kindai University Moreover, axolotl, lungfishes, and coelacanth were found to have TAS1R5. The researchers observed a close evolutionary relationship between TAS1R5, TAS1R1, and TAS1R2, indicating a shared ancestry between these genes. The cartilaginous fishes possess TAS1R6 exclusively. Notably, the researchers found that TAS1R6 evolved from the same ancestral gene that led to TAS1R1, TAS1R2, and TAS1R5 genes. While axolotl and lizards possess TAS1R7, bichir and lungfishes possess TAS1R8. The researchers determined that these two genes originated in the common ancestor of jawed vertebrates. Diversity and Duplication in TAS1R Genes In addition to these new genes, the study revealed diversity in the existing TAS1R genes. For instance, they found that TAS1R3 of bony vertebrates could be divided into TAS1R3A and TAS1R3B. TAS1R3A was present in tetrapods and lungfishes, while TAS1R3B was identified in amphibians, lungfishes, coelacanths, and ray-finned fishes. Additionally, the genome survey found TAS1R2 to have diversified into two distinct groups (TAS1R2A and TAS1R2B), challenging the conventional idea that TAS1R2 forms a single gene group. “We found that the TAS1R phylogenetic tree comprises of a total of 11 TAS1R clades, revealing an unexpected gene diversity,” adds Prof. Nishihara. The findings also suggest that the first TAS1R gene appeared in jawed vertebrates around 615–473 million years ago. The gene then underwent several duplications to produce nine taste receptor genes (TAS1R1,2A, 2B, 3A, 3B, 4, 5, 7, and 8) in the common ancestor of bony vertebrates. Over time, some of these genes were lost in different lineages, with mammals and teleosts retaining only three TAS1Rs (TAS1R1, TAS1R2A, and TAS1R3A in mammals). In addition to shedding light on the evolutionary history, the findings also have practical applications. Explaining these to us, Prof. Nishihara says, “These findings make it easier for us to deduce the taste preferences of diverse vertebrates. This, in turn, can have potential applications such as the development of pet foods and attractants tailored to the preferences of fish, amphibians, and reptiles.”

Researchers with the Conservancy of Southwest Florida observed this 15-foot-long Burmese python swallowing a 77-pound deer in the Everglades National Park. Credit: Ian Bartoszek/Conservancy of Southwest Florida Studies indicate Burmese pythons’ gape size is bigger than previously thought, allowing them to consume larger prey and significantly impact Florida’s ecosystem by preying on larger animals. A new study published in the journal Reptiles & Amphibians shows that Burmese pythons can consume far larger prey than previously believed. Thus, they pose a greater threat to wildlife in southern Florida, where these non-native, invasive snakes have already decimated populations of foxes, bobcats, raccoons, and other animals. Gape Measurements Reveal Surprising Data Pythons swallow deer, alligators, and other prey whole. Their diet is partially limited by the size of the prey they can wrap their flexible, stretchy jaws around, which researchers refer to as a snake’s gape. According to University of Cincinnati Professor Bruce Jayne, measurements of snakes captured in and around Everglades National Park show that the biggest pythons have an even bigger gape than mathematical models suggest. Jayne examined three of the largest snakes captured by research partners Ian Easterling and Ian Bartoszek at the Conservancy of Southwest Florida measuring 15, 17, and 19 feet long.University of Cincinnati Bruce Jayne poses with two mounted Burmese python specimens captured in Florida to show the impressive gape of their mouths. The specimen on the left has a 26-centimeter gape compared to the 22-centimeter gape of the snake on the right. But that gives the larger snake’s mouth a 40% bigger area to swallow prey. Credit: Bruce Jayne Researchers previously examined pythons with a gape of 22 centimeters (or 8.7 inches) in diameter. But the largest of the snakes Jayne’s research partners captured had a maximal gape of 26 centimeters (or 10.2 inches). “That doesn’t sound like a lot — just 18% bigger,” Jayne said. However, the total area of the gape increased by a whopping 40%, Jayne said. The largest snakes had a gape circumference of more than 81 centimeters — the equivalent of a 32-inch waist on a pair of pants. Implications of Increased Gape Size These findings indicate that snakes can consume far larger prey than was previously known. Based on prey items researchers found inside Burmese pythons, researchers know they will kill and consume animals nearly too big to swallow. Researchers observed one snake consuming a 77-pound deer representing two-thirds of the snake’s total mass. “Watching an invasive apex predator swallow a full-sized deer in front of you is something that you will never forget,” Bartoszek said.”The impact the Burmese python is having on native wildlife cannot be denied. This is a wildlife issue of our time for the Greater Everglades ecosystem.” Credit: University of Cincinnati Knowing the limits on the size of prey that predators can eat can help researchers predict the ecological impact the invasive snakes might have as they move into new areas. Burmese pythons are native to the rainforests of Southeast Asia. They were introduced to the wilds of Florida through the pet trade as escapees and intentional releases from irresponsible owners. Python Anatomy and Growth What gives pythons the ability to eat such large animals is their incredible mouths. The lower jawbone is not fused at the front allowing the jaws to stretch wide. Their skin is so soft and super stretchy that it accounts for more than half the circumference of their gape, allowing the pythons to consume prey six times bigger than that of other similar-sized snake species. Researchers examined the scaling relationship between the snake’s gape and its cranial anatomy and overall size to understand its predatory capabilities. Burmese pythons are about 24 inches long and weigh about 4 ounces when they hatch, but they grow fast. They can double their length and body weight in a year. The biggest adults can stretch nearly 20 feet and weigh more than 200 pounds. “Big pythons longer than 16 feet are very rare. Of the more than 9,000 pythons that contractors have captured in Florida, less than 1% were of that extreme size,” Jayne said. Conservation Efforts in Response to Invasive Species The Conservancy of Southwest Florida began its Burmese python research and removal efforts in southern Florida in 2013. A biologist with the Conservancy of Southwest Florida holds a 15-foot-long Burmese python. Credit: Ian Bartoszek/Conservancy of Southwest Florida The group tracked the movements of 120 radio-tagged adult pythons known as “scout snakes” to better understand the invasive population. Its primary objective is to create a database of behavior and habitat use to better understand python activity. This research helps to inform policymakers, biologists, and land managers to develop better control strategies for the invasive snakes. Conclusion and Research Implications Bartoszek and his team have removed 770 pythons, collectively weighing more than 33,000 pounds, that are large enough at 6.5 feet or more to eat an animal at least the size of a baby deer. If each of these snakes were to consume just one deer as big as they could swallow, Jayne estimates that would represent a staggering 13,000 pounds of prey. Jayne said this enormous capacity to eat prey is a big concern if pythons spread to other parts of Florida and potentially the rest of the American Southeast. Burmese pythons are showing up in more places across Florida. “That’s the tip of the iceberg of this phenomenal impact on prey populations in Florida,” he said. “Researchers are trying to get a handle on where the spread might stop.” Reference: “Big pythons, big gape, and big prey” by Bruce C.

Senescent cells, or “zombie cells,” are unique in that they ultimately cease multiplying but do not die off as expected. Researchers have found a new pathway for the buildup of “zombie cells,” which promote aging. Senescent cells, or cells that have lost their ability to divide, increase with age and are major contributors to age-related illnesses such as cancer, dementia, and cardiovascular disease. In a new study, a team led by the University of Pittsburgh and UPMC Hillman Cancer Center researchers discovered a method through which senescent, or “zombie,” cells develop. Patricia Opresko, Ph.D., professor of environmental and occupational health and of pharmacology and chemical biology at the University of Pittsburgh and co-leader of the Genome Stability Program at UPMC Hillman Cancer Center. Credit: Patricia Opresko The study, which was recently published in the journal Nature Structural & Molecular Biology, demonstrates for the first time that oxidative damage to telomeres — the protecting tips of chromosomes that behave like plastic caps at the end of a shoelace — can cause cellular senescence. These discoveries might ultimately result in new treatments that promote healthy aging or fight cancer. “Zombie cells are still alive, but they can’t divide, so they don’t help replenish tissues,” said senior author Patricia Opresko, Ph.D., professor of environmental and occupational health and of pharmacology and chemical biology at Pitt. “Although zombie cells don’t function properly, they’re not couch potatoes — they actively secrete chemicals that promote inflammation and damage neighboring cells. Our study helps answer two big questions: How do senescent cells accumulate with age, and how do telomeres contribute to that?” When a healthy human cell divides to create two identical cells, a little bit of DNA is shaved off the tip of each chromosome, causing telomeres to get shorter with each division. However, it is unknown if a cell may divide so often in a person’s lifetime that its telomeres fully degrade, resulting in a zombie-like condition. For decades, scientists have known that telomere shortening causes senescence in lab-grown cells, but they could only assume that DNA damage at telomeres could convert cells into zombies. This hypothesis could not previously be tested since the techniques used to damage DNA were non-specific, creating lesions across the entire chromosome. “Our new tool is like a molecular sniper,” explained first author Ryan Barnes, Ph.D., a postdoctoral fellow in Opresko’s lab. “It creates oxidative damage exclusively at the telomeres.” X-shaped chromosomes are stained purple, and telomeres appear as green spots at chromosome tips. When researchers used a novel tool to induce oxidative damage specifically at telomeres, they can become fragile (green arrows), sending cells into senescence. The inset shows an enlarged chromosome with fragile telomeres, indicated by multiple green spots at chromosome tips. Credit: Barnes et al., Nature Structural & Molecular Biology, (2022) To develop such marksman-like precision, the team used a special protein that binds exclusively to telomeres. This protein acts like a catcher’s mitt, grabbing hold of light-sensitive dye “baseballs” that the researchers tossed into the cell. When activated with light, the dye produces DNA-damaging reactive oxygen molecules. Because the dye-catching protein binds only to telomeres, the tool creates DNA lesions specifically at chromosome tips. Accelerated Senescence Due to Telomere Damage Ryan Barnes, Ph.D., a postdoctoral fellow at the University of Pittsburgh. Credit: Ryan Barnes Using human cells grown in a dish, the researchers found that damage at telomeres sent the cells into a zombie state after just four days — much faster than the weeks or months of repeated cell divisions that it takes to induce senescence by telomere shortening in the lab. “We found a new mechanism for inducing senescent cells that is completely dependent on telomeres,” explained Opresko, who also co-leads the Genome Stability Program at UPMC Hillman. “These findings also solve the puzzle of why dysfunctional telomeres are not always shorter than functional ones.” Sunlight, alcohol, smoking, poor diet, and other factors generate reactive oxygen molecules that damage DNA. Cells have repair pathways to patch up DNA lesions, but, according to Opresko, telomeres are “exquisitely sensitive” to oxidative damage. The researchers found that damage at telomeres disrupted DNA replication and induced stress signaling pathways that led to senescence. Potential for New Interventions and Senolytic Drugs “Now that we understand this mechanism, we can start to test interventions to prevent senescence,” said Barnes. “For example, maybe there are ways to target antioxidants to the telomeres to protect them from oxidative damage.” The findings could also inform the development of new drugs called senolytics that home in on zombie cells and kill them. “By reducing the accumulation of zombie cells, which contribute to degenerative diseases, we might be able to promote ‘healthspan’ — the length of time that a person is healthy,” he added.
