Credit: Roderich Roemhild Understanding resistance rates and cross-resistance can improve the potency of sequential antibiotic treatment protocols. Sequential treatment using antibiotics that are similar but swapped around frequently is an effective way to kill bacteria and prevent drug resistance, a study in eLife reports. The results challenge a broad assumption that using similar antibiotics promotes cross-resistance to drugs, and show that available antibiotics could offer unexplored, highly potent treatment options. “We are currently in an antibiotic crisis, where the overuse of antibiotics is leading to increased antibiotic resistance and certain infections have become difficult and even impossible to treat,” says first author Aditi Batra, a graduate student at the Max Planck Institute for Evolutionary Biology and the University of Kiel, Germany. “It is the ability of pathogens to evolve and adapt to drugs that underlies this resistance, but evolutionary theory predicts that adaptation is difficult when the environment changes rapidly. We wanted to test if we could use sequential antibiotic treatment to slow down the evolution of human pathogens and limit drug resistance.” The team used bacteria called Pseudomonas aeruginosa (P. aeruginosa), which can cause pneumonia and other infections in humans. They tested three different sequences of antibiotics under laboratory conditions and measured their potency at killing off different sub-populations of evolved bacterial cells. Two sets of antibiotics belonged to a class of drugs called ß-lactams, which have a common structural component – a ß-lactam ring. The other set of antibiotics all worked by different mechanisms. To the team’s surprise, treatment with both sets of ß-lactam antibiotics was better at killing off bacterial populations than some of the unrelated antibiotics. Moreover, switching rapidly between the individual antibiotics produced much better extinction of bacterial populations than when the switch between antibiotics was slower. This suggests that fast switching between antibiotics constrained the bacteria’s ability to adapt to the drugs. Given this unexpected result, the team explored the mechanisms that cause this evolutionary constraint. They studied the changes in growth, resistance profiles and whole genome sequences of the P. aeruginosa populations treated with the most potent sequence of ß-lactam antibiotics, which combined carbenicillin, doripenem and cefsulodin. They noted that when the sequences were switched quickly, bacterial growth during a switch to doripenem was much lower than for the other two antibiotics, indicating that resistance to this drug might emerge more slowly. They also looked at whether physiological changes that occur as a result of drug treatment made the bacteria resistant or more susceptible to the other drugs in the sequence. They found that spontaneous development of resistance was much lower for doripenem than the other two drugs. There was also less cross-resistance towards this drug than the other two antibiotics. This lack of cross-resistance may indicate the presence of so-called collateral sensitivity; this means that the mutant cells, which have become resistant to one drug, maintain at least ancestral levels of susceptibility against the second drug. Collateral sensitivity is known to be important for the effectiveness of sequential treatment. “Although sequential treatments with such similar antibiotics should have sped up resistance evolution, we found this is not the case if resistance to one of the antibiotics cannot emerge easily, and if the antibiotics show collateral sensitivity to each other,” says senior author Hinrich Schulenburg, Fellow of the Max Planck Institute for Evolutionary Biology and Professor at the University of Kiel. “It is ironic that the differential cross-resistance profile of the ß-lactam drugs was a key factor to treatment potency, even though this is usually used to reject treatment that exclusively uses these drugs. Our study shows that spontaneous resistance rates of component antibiotics could be used as a guiding principle for sequential treatments and could improve the potency of sequential protocols.” This study has been published as part of ‘Evolutionary Medicine: A Special Issue’ from eLife.

DOI: 10.7554/eLife.68876 Vertebrate evolution timeline. Credit: Dr. Guojie Zhang A new study reveals that the genetic basis for limbs and lungs predates the vertebrate land transition by 50 million years, reshaping our understanding of human evolutionary history. People traditionally think that lungs and limbs are key innovations that came with the vertebrate transition from water to land. But in fact, the genetic basis of air-breathing and limb movement was already established in our fish ancestor 50 million years earlier. This, according to a recent genome mapping of primitive fish conducted by the University of Copenhagen, among others. The new study changes our understanding of a key milestone in our own evolutionary history. There is nothing new about humans and all other vertebrates having evolved from fish. The conventional understanding has been that certain fish shimmied landwards roughly 370 million years ago as primitive, lizard-like animals known as tetrapods. According to this understanding, our fish ancestors came out from water to land by converting their fins to limbs and breathing under water to air-breathing. However, limbs and lungs are not innovations that appeared as recent as once believed. Our common fish ancestor that lived 50 million years before the tetrapod first came ashore already carried the genetic codes for limb-like forms and air breathing needed for landing. These genetic codes are still present in humans and a group of primitive fishes. This has been demonstrated by recent genomic research conducted by University of Copenhagen and its partners. The new research reports that the evolution of these ancestral genetic codes might have contributed to the vertebrate water-to-land transition, which changes the traditional view of the sequence and timeline of this big evolutionary jump. The study has been published in the scientific journal Cell. “The water-to-land transition is a major milestone in our evolutionary history. The key to understanding how this transition happened is to reveal when and how the lungs and limbs evolved. We are now able to demonstrate that the genetic basis underlying these biological functions occurred much earlier before the first animals came ashore,” stated professor and lead author Guojie Zhang, from Villum Centre for Biodiversity Genomics, at the University of Copenhagen’s Department of Biology. A group of ancient living fishes might hold the key to explaining how the tetrapod ultimately could grow limbs and breathe in air. The group of fish includes the bichir that lives in shallow freshwater habitats in Africa. These fishes differ from most other extant bony fishes by carrying traits that our early fish ancestors might have had over 420 million years ago. And the same traits are also present in, for example, humans. Through genomic sequencing, the researchers found that the genes needed for the development of lungs and limbs have already appeared in these primitive species. Our Synovial Joint Evolved From Fish Ancestor Using pectoral fins with a locomotor function like limbs, the bichir can move about on land in a similar way to the tetrapod. Researchers have for some years believed that pectoral fins in bichir represent the fins that our early fish ancestors had. The new genome mapping shows that the joint which connects the socalled metapterygium bone with the radial bones in the pectoral fin in the bichir is homologous to synovial joints in humans — the joints that connect upper arm and forearm bones. The DNA sequence that controls the formation of our synovial joints already existed in the common ancestors of bonefish and is still present in these primitive fishes and in terrestrial vertebrates. At some point, this DNA sequence and the synovial joint was lost in all of the common bony fishes — the so-called teleosts. “This genetic code and the joint allows our bones move freely, which explains why the bichir can move around on land,” says Guojie Zhang. First Lungs, Then Swim Bladder Moreover, the bichir and a few other primitive fishes have a pair of lungs that anatomically resembles ours. The new study reveals that the lungs in both bichir and alligator gar also function in a similar manner and express same set of genes as human lungs. At the same time, the study demonstrates that the tissue of the lung and swim bladder of most extant fishes are very similar in gene expression, confirming they are homologous organs as predicted by Darwin. But while Darwin suggested that swim bladders converted to lungs, the study suggests it is more likely that swim bladders evolved from lungs. The research suggests that our early bony fish ancestors had primitive functional lungs. Through evolution, one branch of fish preserved the lung functions that are more adapted to air breathing and ultimately led to the evolution of tetrapods. The other branch of fishes modified the lung structure and evolved with swim bladders, leading to the evolution of teleosts. The swim bladders allow these fishes to maintain buoyancy and perceive pressure, thus better survive under water. “The study enlightens us with regards to where our body organs came from and how their functions are decoded in the genome. Thus, some of the functions related to lung and limbs did not evolve at the time when the water-to-land transition occurred, but are encoded by some ancient gene regulatory mechanisms that were already present in our fish ancestor far before landing. It is interesting that these genetic codes are still present in these ‘living-fossil” fishes, which offer us the opportunity to trace back the root of these genes,” concludes Guojie Zhang. FACT BOX 1: Not just limbs and lungs, but also the heart Primitive fish and humans also share a common and critical function in the cardio-respiratory system: The conus arteriosus, a structure in the right ventricle of our heart which might allow the heart to efficiently deliver the oxygen to the whole body, and which is also found in the bichir. However, the vast majority of bony fish have lost this structure. The researchers discovered a genetic element that appears to control the development of the conus arteriosus. Transgenic experiments with mice showed that when researchers removed this genetic element, the mutated mice died due to thinner, smaller right ventricles, which lead to congenital heart defects and compromised heart function. FACT BOX 2: The vast majority of extant fish species belong to the ray-finned fishes, a subclass of bony fish. These are typically fish with gills, fins and a swim bladder. The terrestrial group of vertebrates are known as tetrapod. The tetrapod includes all vertebrates that descended from the first animals adapted to a life on land by developing four limbs and lungs, i.e., all mammals, birds, reptiles and amphibians. The researchers’ theory is that the air-breathing ability in these primitive fishes allowed them to survive the second mass extinction roughly 375-360 million years ago. At that time, oxygen depletion in Earth’s oceans caused a majority of species to be wiped out. Lungs allowed some fish to survive on land. The study has been published in the scientific journal Cell. The research team also contributed to another paper which reported the genome for another primitive fish, the lungfish. The genome is the biggest vertebrate genome decoded so far. This paper was published in Cell at the same time. The research is supported by the Villum Foundation, among others.

University of California Riverside-led study identifies how blood stem cells maintain their fate. Understanding the molecular mechanisms that specify and maintain the identities of the human body’s more than 200 cell types is perhaps one of the most fundamental problems in molecular and cellular biology, with major implications for human disease management. Stem cells, which exist in every tissue of the body, play a critical role in the cell fate decision process. When stem cells divide, they have the extraordinary potential to self-renew — that is, to replicate themselves — or to develop into specified lineages. The study of a research team led by biochemists at the University of California, Riverside has improved our understanding of how a distinct lineage identity is maintained every time a stem cell divides. The research study led by Sihem Cheloufi and Jernej Murn, both assistant professors in the Department of Biochemistry, shows how a protein complex, called chromatin assembly factor-1, or CAF-1, controls genome organization to maintain lineage fidelity. The report will be published today (April 29, 2022) in the journal Nature Communications. Sihem Cheloufi (left) and Jernej Murn are assistant professors of biochemistry at UC Riverside. Credit: Stan Lim, UC Riverside Each time a cell divides, it has to create a replica of its genome — not only its DNA sequence but also how the DNA is packaged with proteins into chromatin. Chromatin is organized into genomic sites that are either open and easily accessible or more densely packed and less accessible (or closed). “Identities of different cells rely heavily on the genome sites that are more open because only genes located in those regions can potentially become expressed and turned into proteins,” Cheloufi explained. She added that to maintain cell identity during cell division, the locations of open and closed chromatin, or “chromatin organization,” must be faithfully passed onto the new replica of the genome, a task largely entrusted to CAF-1. “To help CAF-1 secure correct chromatin organization during cell division, a host of transcription factors are attracted to open regions in a DNA sequence-specific manner to serve as bookmarks and recruit transcription machinery to correct lineage-specific genes, ensuring their expression,” she said. “We wondered about the extent to which CAF-1 is required to maintain cell-specific chromatin organization during cell division.” Research on Blood Cell Lineage and CAF-1 The authors took as a study paradigm immature blood cells that can either self-renew or turn into neutrophils, which are non-dividing cells that present our body’s first line of defense against pathogens. Intriguingly, they found CAF-1 to be essential not only for maintaining the self-renewal of these immature blood cells, but for preserving their lineage identity. Even a moderate reduction of CAF-1 levels caused the cells to forget their identity and adopt a mixed lineage stage. “Neutrophil stem cells missing CAF-1 become more plastic, co-expressing genes from different lineages, including those of red blood cells and platelets,” Cheloufi said. “This is very intriguing from a developmental biology perspective.” Image shows mouse blood cells — a mix of stem and progenitor cells, differentiated neutrophils and mixed identity cells. Credit: Meijuan Chen, Cheloufi lab, UC Riverside ELF1 and Aberrant Chromatin Sites At the molecular level, the team found that CAF-1 normally keeps specific genomic sites compacted and inaccessible to specific transcription factors, especially one called ELF1. “By looking at chromatin organization, we found a whole slew of genomic sites that are aberrantly open and attract ELF1 as a result of CAF-1 loss,” Murn said. “Our study further points to a key role of ELF1 in defining the fate of several blood cell lineages.” The UCR researchers used immature blood cells derived from mouse bone marrow and engineered for growth in tissue culture. They validated their findings in vivo using a mouse model in collaboration with Andrew Volk, a hematology expert at the Cincinnati Children’s Hospital Medical Center and a co-corresponding author on the study. Next, Cheloufi and her colleagues would like to understand the mechanism by which CAF-1 preserves the chromatin state at specific sites and whether this process works differently across different cell types. “Like a city, the genome has its landscape with specific landmarks,” Cheloufi said. “It would be interesting to know how precisely CAF-1 and other molecules sustain the genome’s ‘skyline.’ Solving this problem could also help us understand how the fate of cells could be manipulated in a predictive manner. Given the fundamental role of CAF-1 in packaging the genome during DNA replication, we expect it to act as a general gatekeeper of cellular identity. This would in principle apply to all dividing cells across numerous tissues, such as cells of the intestine, skin, bone marrow, and even the brain.” Reference: “Regulation of Chromatin Accessibility by the Histone Chaperone CAF-1 Sustains Lineage Fidelity” by Reuben Franklin, Yiming Guo, Shiyang He, Meijuan Chen, Fei Ji, Xinyue Zhou, David Frankhouser, Brian T.
