Lewismorpho Despite lung loss in adults for millions of years, lungless salamanders develop lungs as embryos. For many vertebrates, including humans, their lungs are essential. Four living amphibian clades, however, no longer breathe via their lungs and instead breathe predominantly through their wet skin. Little is known about the developmental basis of lung loss in these clades. Researchers at Harvard University’s Museum of Comparative Zoology and Department of Organismic and Evolutionary Biology examined the Plethodontidae, a dominant family of salamanders that are all lungless as adults, and discovered that they do develop lungs as embryos, providing insight into the evolution of lung loss over millions of years. Their findings were recently published in the journal Science Advances. Plethodontidae: Evolutionary Success Without Lungs Plethodontidae is the most species-rich salamander family, accounting for more than two-thirds of all current salamander diversity. All adult plethodontids lack lungs and breathe solely through nonpulmonary tissues, primarily the skin and mucus membranes of the mouth and throat. Lung loss has happened at least four times in distantly related amphibians independently, and there are more cases of lung reduction or loss in both amphibians as well as some vertebrates. However, the developmental explanation for this loss is unknown. “Clearly lungless salamanders do fine without lungs given that they make up about two-thirds of all salamander species,” said lead author Zachary R. Lewis, former doctoral candidate (Ph.D.’16), “perhaps losing lungs enabled, rather than hindered, this remarkable evolutionary success.” Investigating Lung Development in Embryos This research builds on Lewis’ doctoral work in the lab of senior author Professor James Hanken. Lewis, Hanken, and co-author Associate Professor Ryan Kerney of Gettysburg College examined the morphology of lung development in both lung and lungless salamanders using histology and micro-CT. They discovered that lungless salamanders develop lungs as embryos in the same manner as lungs develop in other species. The researchers subsequently employed in situ hybridization and RNA sequencing to demonstrate that the structure that arises during lungless salamander embryonic development is similar to a lung not just morphologically, but also in terms of the molecules expressed. The researchers suggest that lung development stops in these species due to a lack of cues that maintain lung development, which emerge from the tissue, mesenchyme, that surrounds the developing lung. Mesenchyme’s Role in Lung Development “We put mesenchyme from a salamander with lungs into a lungless salamander embryo and allowed it to develop,” said Lewis, “it resulted in the formation of structures that resemble lungs, offering some evidence that lungless salamanders remain capable of continuing to develop lungs.” The study also confirms Amy Grace Mekeel’s 1936 doctoral thesis that challenged the leading theory put forth by biologists that the slight fold in the adult pharynx is a vestigial lung which persisted since the initial lung loss of the plethodontids. Mekeel described a “lung rudiment” that formed in the embryo but was lost by the time it hatched. “The lung precursor appears and disappears before the lungless salamander embryos hatch, just as Mekeel described,” said Kerney, “this work vindicates Mekeel’s earlier thesis and lays the initial adult vestige hypothesis to rest.” The study reveals that lung developmental-genetic pathways are at least partially conserved despite the absence of functional adult lungs for at least 25 and possibly exceeding 60 million years. Understanding the evolution of lung loss in Plethondontidae could also shed light on organ loss in other vertebrates. “In the future, if these genetic mechanisms are revealed, we will have a more complete understanding of how evolution acts to do away with an organ such as the lung, which was long thought critical to achieving life on land,” said Lewis who is currently a scientist with NanoString Technologies.

Researchers have developed a groundbreaking method called Zman-seq for tracking changes over time in single cells within the body. This method, which marks cells with time stamps, has significantly advanced our understanding of cellular dynamics, particularly in understanding diseases like glioblastoma. Zman-seq’s ability to trace the history and sequence of molecular and cellular changes offers a new perspective in the study of complex biological systems and paves the way for developing more effective therapies for cancer and other disorders. The technique known as Zman-seq uncovers the history of cells, potentially propelling the creation of innovative treatments for cancer and various other diseases. While physicists continue to debate over Albert Einstein’s assertion that time is an illusion, biologists are certain about its importance in comprehending life as a dynamic system. Recently, biologists have deepened their understanding of intricate biological systems. They have achieved this by using advanced tools that allow for the analysis of large quantities of cellular and molecular data, and by examining the cellular networks responsible for diseases.However, these in-depth investigations of how cells behave and interact have provided only separate snapshots of what happens inside complex organisms, without accounting for the dimension of time and revealing the sequence of cellular events. Now, in a new study recently published in Cell, researchers from Prof. Ido Amit’s lab at the Weizmann Institute of Science have managed for the first time to develop a method for tracking and measuring changes over time on in single cells inside the body. The method, called Zman-seq (from the Hebrew word zman, for “time”), consists of labeling cells with different time stamps and tracking them in healthy or pathological tissue. Using this cellular time machine, researchers can get to know the cells’ history and how long each cell had stayed in the tissue, ultimately achieving an understanding of the molecular and cellular temporal changes that had taken place within that tissue. The Advancements and Limitations of Single-Cell Technologies Single-cell technologies, the tools that enable biologists to understand what happens inside individual cells, have advanced significantly in recent years, in large part thanks to the vibrant single-cell research community in which Amit’s lab is one of the pioneers. With these tools, it is now possible to obtain high-resolution images of how diseases develop and how the body responds to different medications, to identify rare cell populations, decipher which cells interact with one other and how they are spatially distributed in a tissue. However, all these important insights are equivalent to getting many still-frame images from a movie and trying to understand the plot. “Knowing what preceded what is not enough to deduce causality, but without this knowledge, we don’t really have a chance of understanding what the cause is and what is the effect,” Amit says. The development of the groundbreaking new technology started with the research of Dr. Daniel Kirschenbaum, a postdoctoral researcher in Amit’s lab. Kirschenbaum was born in Hungary and did his PhD in neuropathology in Switzerland, where he studied glioblastoma, the most common and aggressive brain tumor. “We usually think of cancer as cells growing out of control, but in fact, cancer is also the loss of the ability of the body, and specifically of its immune system, to control this growth,” he says. “And when you look at tumors, large parts of them are composed of dysfunctional immune cells, which sometimes make up one-third or even half of all the cells in a tumor.” Glioblastoma is one of the most immune-suppressive types of tumors. “To understand how to defeat this cancer, we need to understand what happens to the immune cells as they enter the tumor and why they lose the capacity to fight the tumor and become dysfunctional,” Kirschenbaum explains. “Ideally, we’d want to have a little clock on each cell telling us when it entered the tumor and when the signals and checkpoints that instruct it to become incompetent are activated. This back-to-the-future time machine was thought to be impossible to develop.” The breakthrough came when Kirschenbaum decided to take an uncanny approach. “Instead of trying to measure time in cells within the tumor tissue, we decided to try to mark the cells while they are still in the blood – before they enter the tumor. By using different fluorescent dyes at different time points, we are later able to know exactly when each cell entered the tissue and how long it had been there, and this reveals the dynamic changes that happened to the cells in the tissue, for example, what are the different stages at which immune cells become dysfunctional inside the tumor.” Methodology and Insights from Zman-seq The challenge, Kirschenbaum adds, was to develop the optimal way to color the cells in the blood at specific time points, making sure the dye does not reach the tissue itself or stay too long in the blood, potentially mixing with the next dye. At the same time, the dye had to stay on the cells long enough for them to be measured. As part of the study, the researchers in Amit’s lab showed that the method makes it possible to measure time in immune cells in different tissues – the brain, the lungs, and the digestive system of animal models. Using Zman-seq, Kirschenbaum and his colleagues were able to gain insights into why the immune system is so dysfunctional in battling glioblastoma. “For example, we showed that immune cells called natural killer cells, which, as their name implies, are crucial to killing rogue cells, become dysfunctional very quickly because the tumor hijacks their killing mechanisms – and this happens within less than 24 hours after their entry into the tumor. This explains why therapeutic attempts to harness the immune system for fighting glioblastoma are so ineffective,” Kirschenbaum says. Other members of Amit’s lab in Weizmann’s Systems Immunology Department, including Dr. Ken Xie and Dr. Florian Ingelfinger, contributed to the development of Zman-seq. Collaborators included immunologists Prof. Marco Colonna of Washington University, Prof. Katayoun Rezvani of the University of Texas, Prof. Florent Ginhoux of the Shanghai Institute of Immunology, neurooncologist Dr. Tobias Weiss of the University Hospital Zurich, and computational biologists Prof. Fabian J. Theis of the Helmholtz Center Munich and Prof. Nir Yosef of the Weizmann Institute. Now, researchers in Amit’s lab are developing ways to block the immune-disabling tumor checkpoints in order to reactivate the immune system in glioblastoma and other hard-to-treat tumors. In addition, they plan to adapt Zman-seq to the study of temporal dynamics of cells throughout the human body. “For example, many cancer patients are getting therapy before surgery. We want to use the method to color immune cells in the body during that period so that after the surgery, we can better understand the dynamics of immune cells in the tumor and optimize patient treatments,” adds Kirschenbaum. “Until today, there were quite a few different methods trying to analyze single-cell data and arranging them along a time axis according to different parameters. But these approaches were all somewhat arbitrary in choosing what are the sequence of events,” Amit says. “Zman-seq supplies the ‘hard facts,’ the empirical measurements enabling scientists to understand the precise order of events that immune and other cells are going through when they enter a tumor, and this may lead to a completely new thinking on how to generate more effective therapies for cancer and other disorders.” Reference: “Time-resolved single-cell transcriptomics defines immune trajectories in glioblastoma” by Daniel Kirschenbaum, Ken Xie, Florian Ingelfinger, Yonatan Katzenelenbogen, Kathleen Abadie, Thomas Look, Fadi Sheban, Truong San Phan, Baoguo Li, Pascale Zwicky, Ido Yofe, Eyal David, Kfir Mazuz, Jinchao Hou, Yun Chen, Hila Shaim, Mayra Shanley, Soeren Becker, Jiawen Qian, Marco Colonna, Florent Ginhoux, Katayoun Rezvani, Fabian J.

Sudden burst of evolution 66 million years ago expanded snake diets and put vertebrates on the menu. The remarkable diversification of mammals and birds after the demise of the dinosaurs 66 million years ago is well known; but what happened to the snakes? According to a study published in the open-access journal PLOS Biology by Michael Grundler at the University of California, Los Angeles and Daniel Rabosky at the University of Michigan, snakes experienced a similarly spectacular burst of evolution from unassuming insectivorous ancestors to diverse lineages that included the newly available birds, fish and small mammals in their diets. The K-Pg mass extinction event 66 million years ago – during which 75% of species, including all non-avian dinosaurs, went extinct – marked the beginning of the Cenozoic era and opened a myriad of empty niches for the surviving species to exploit. Like mammals and birds, snakes diversified rapidly during the Cenozoic era, resulting in the nearly 4,000 species that we see today. To better understand the pace and sequence of this phenomenon, the researchers collated published data on the diets of 882 living snake species and used sophisticated mathematical models to reconstruct how the diets of their ancestors changed and diversified since the K-Pg boundary. They found that the most recent common ancestor of living snakes was insectivorous, but after the K-Pg boundary, snake diets rapidly expanded to include birds, fish, and small mammals – vertebrate groups that were also flourishing in the wake of the dinosaurs’ extinction.

These species show considerable variability in their diets, ranging from generalist predators on vertebrates (rainbow boa, anaconda) to species that specialize on sleeping lizards (tree snake), earthworms (worm snake), and tree frogs (parrot snake). The study sheds light on the explosive adaptive radiation that gave rise to modern snake diversity. Diet diversification in snakes slowed after the initial radiation, but some lineages experienced further bursts of adaptive evolution. For example, Colubroid snakes diversified when Old World ancestors colonized North and South America. These findings show that mass extinctions and new biogeographic opportunities can spur evolutionary change, the authors say. “Much of the stunning ecological diversity in snakes seems to result from evolutionary explosions triggered by ecological opportunity,” Grundler adds. “We find a major burst of snake diet diversification after the dinosaur extinction, and we also find that, when snakes arrive in new places, they often undergo similar bursts of dietary diversification.” For more on this research, read Snakes Diversified Explosively After Mass Extinction Where Dinosaurs Were Wiped Out.
