An LNP is located on a long endosomal tubule (green), together with a perpendicular disperse mRNA signal (cyan), and likely representing an instance of mRNA (purple) escape. Credit: Marino Zerial / MPI-CBG Researchers have found where and how mRNA arrives in a cell to modify or deliver genetic information, a crucial process for the development of novel therapies. DNA (deoxyribonucleic acid) contains the genetic information required for the development and maintenance of life. This information is communicated by messenger ribonucleic acid (mRNA) to make proteins. mRNA-based therapeutics have the potential to address unmet needs for a wide variety of diseases, including cancer and cardiovascular disease. mRNA can be delivered to cells to trigger the production, degradation, or modification of a target protein, something impossible with other approaches. A key challenge with this modality is being able to deliver the mRNA inside the cell so that it can be translated to make a protein. mRNA can be packed into lipid nanoparticles (LNPs) – small bubbles of fat – that protect the mRNA and shuttle it into cells. However, this process is not simple, because the mRNA has to pass the membrane before it can reach its site of action in the cell interior, the cytoplasm. Researchers in the team of MPI-CBG director Marino Zerial are experts in visualizing the cellular entry routes of molecules in the cell, such as mRNA with high-resolution microscopes. They teamed up with scientists from AstraZeneca who provided the researchers with lipid nanoparticle prototypes that they had developed for therapeutic approaches to follow the mRNA inside the cell. The study is published in the Journal of Cell Biology.  “To be delivered, the mRNA must make a long journey. Enclosed in the fatty LNP bubble, it needs to get into the cell first,” explains Marino Zerial. “The LNPs arrive at the cell surface where they bind to receptors. They are then taken up into specialized membrane-enclosed compartments called endosomes. At this point, the mRNA is inside the cells but surrounded by two barriers, the fatty bubble and the endosome wall or more correctly, the membrane. The challenge for the mRNA is to escape both barriers to reach the cytoplasm where it serves as a template to make proteins. We know that only a tiny fraction of RNA molecules are able to escape into the cytoplasm.” Internalized cargo molecules, like the LNPs, are first transported to “early” endosomes. These are logistic centers that distribute cargo molecules to various destinations in the cell. They either recycle molecules to the cell surface or degrade them in late endosomes and lysosomes. So far, people thought that the mRNA escapes from late endosomes by exploiting their very acidic content. “With single molecule microscopy techniques,” explains Prasath Paramasivam, the first author of the study, “we could visualize for the first time the mRNA in the LNP inside the endosomes of cells. We also captured the actual escape of the mRNA, which happened in the tubules of the recycling endosomes, which are only mildly acidic. Our results imply that sending the LNP-mRNA to late endosomes is counterproductive for delivery and only increases cell toxicity,” says Zerial. These findings help in understanding the mechanism of mRNA escape from endosomes in more detail. Marino Zerial summarizes: “The LNP delivery system for mRNA necessitates high doses due to the low endosomal escape efficiency. Knowing where the mRNA goes and how it can escape the endosomes allows us to develop better vehicles for more efficient delivery, at lower dosage. We can improve the mRNA delivery system so it can be used for therapeutic applications, for example, cancer treatment.” Reference: “Endosomal escape of delivered mRNA from endosomal recycling tubules visualized at the nanoscale” by Prasath Paramasivam, Christian Franke, Martin Stöter, Andreas Höijer, Stefano Bartesaghi, Alan Sabirsh, Lennart Lindfors, Marianna Yanez Arteta, Anders Dahlén, Annette Bak, Shalini Andersson, Yannis Kalaidzidis, Marc Bickle and Marino Zerial, 9 December 2021, Journal of Cell Biology.

A new study explores the significance of the genetic information absent in the human genome compared to other primates. The researchers found that humans lost around 10,000 fragments of genetic information over evolutionary history, which differentiate us from our closest primate relatives, like chimpanzees. Some of these “deleted” fragments relate to neuronal and cognitive functions, including those involved in brain cell formation. These deletions, present in other mammals but absent in humans, became conserved across all humans, suggesting they provided a biological advantage. The team used Massively Parallel Reporter Assays (MPRA) technology to screen and measure the function of thousands of genetic changes among species, contributing to our understanding of what makes humans unique. Researchers from Yale and the Broad Institute discovered that the loss of about 10,000 fragments of genetic information differentiates humans from our closest primate relatives. These conserved deletions, associated with cognitive functions and brain cell formation, suggest an evolutionary advantage, altering the function of our genes and potentially contributing to our unique human characteristics. What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and the Broad Institute of MIT and Harvard. The new findings, published recently in the journal Science, fill an important gap in what is known about historical changes to the human genome. While a revolution in the capacity to collect data from genomes of different species has allowed scientists to identify additions that are specific to the human genome — such as a gene that was critical for humans to develop the ability to speak — less attention has been paid to what’s missing in the human genome. For the new study researchers used an even deeper genomic dive into primate DNA to show that the loss of about 10,000 bits of genetic information — most as small as a few base pairs of DNA — over the course of our evolutionary history differentiate humans from chimpanzees, our closest primate relative. Some of those “deleted” pieces of genetic information are closely related to genes involved in neuronal and cognitive functions, including one associated with the formation of cells in the developing brain. These 10,000 missing pieces of DNA — which are present in the genomes of other mammals — are common to all humans, the Yale team found. Evolutionary Significance of DNA Deletions The fact that these genetic deletions became conserved in all humans, the authors say, attests to their evolutionary importance, suggesting that they conferred some biological advantage. “Often we think new biological functions must require new pieces of DNA, but this work shows us that deleting genetic code can result in profound consequences for traits make us unique as a species,” said Steven Reilly, an assistant professor of genetics at Yale School of Medicine and senior author of the paper. The paper was one of several published in the journal Science from the Zoonomia Project, an international research collaboration that is cataloging the diversity in mammalian genomes by comparing DNA sequences from 240 species of mammals that exist today. Rewriting Genetic Instructions Through Deletions In their study, the Yale team found that some genetic sequences found in the genomes of most other mammal species, from mice to whales, vanished in humans. But rather than disrupt human biology, they say, some of these deletions created new genetic encodings that eliminated elements that would normally turn genes off. The deletion of this genetic information, Reilly said, had an effect that was the equivalent of removing three characters — “n’t” — from the word “isn’t” to create a new word, “is.” “[Such deletions] can tweak the meaning of the instructions of how to make a human slightly, helping explain our bigger brains and complex cognition,” he said. The researchers used a technology called Massively Parallel Reporter Assays (MPRA), which can simultaneously screen and measure the function of thousands of genetic changes among species. “These tools have the capability to allow us to start to identify the many small molecular building blocks that make us unique as a species,” Reilly said.

Four women and three men aged 23-49 years, participated in the hearing tests. The study found that hear much better underwater than previously reported. Humans or Seals? Who Has the Best Underwater Hearing? All mammals lived on land millions of years ago, but eventually, certain species abandoned the land and adapted to life in the sea: take seals and whales, which both can now live underwater. The remainder of the species that persisted on land has similarly adapted to a life on land. That is why it shouldn’t be a surprise that a group of experts came to the conclusion that people today hear better on land than underwater in a recent study. However, the research also offers unexpected information on human hearing. A specialist in animal hearing, Jakob Christensen-Dalsgaard devotes his time and energy to studying the hearing of creatures including cormorants, geckos, frogs, and crocodiles, as well as people, in his laboratory at the University of Southern Denmark. This time, he is working alongside Ph.D. candidate Kenneth Sørensen and biologist Magnus Wahlberg, who is an expert on animal underwater hearing and also attends the University of Southern Denmark.

The US military, for example, has had an interest in understanding how divers are affected by underwater explosions, and in general, the hearing tests have been very different. Some subjects have been tested with diving equipment on, others with neoprene caps, and still others with air-filled diving masks — all of which can affect the test subjects’ hearing. However, the authors state that one thing in common with all of these scientific studies is that they all find hearing thresholds that are higher than the thresholds we have found in their new study. Illustration of how the hearing tests were conducted. Credit: Jakob Christensen-Dalsgaard, University of Southern Denmark. We Hear As Well as Seals Underwater In the new study, in which 7 people participated, the average hearing threshold of 71 dB (3.5 mPa) is at 500 Hz. Hearing threshold is the sound level below which a person’s ear cannot hear anything. “It is 26 dB lower than hypothesized in previous studies, so we must conclude that humans hear significantly better underwater than previously reported by science. In fact, the threshold at 500 Hz is in line with how well animals such as cormorants and seals hear underwater,” says Jakob Christensen-Dalsgaard. Worth noting in this context is, that e.g., seals and dolphins – unlike us — can hear very loud sounds underwater – also sounds that humans cannot hear. The previous studies hypothesized that the human ear underwater works by so-called bone conduction; that is, the sound waves vibrate the skull. That hypothesis would fit the high hearing thresholds found in previous studies. A human and seal underwater.

We have also shown this in previous studies of cormorants, turtles, and frogs,” explains Jakob Christensen-Dalsgaard “You should not expect to be able to jump into the sea and orient yourself perfectly using only your sense of hearing,” says Jakob Christensen-Dalsgaard,  “Sense of hearing is not just about being able to pick up a sound. It is also about determining the direction of the sound — and this is very difficult for a person underwater.” “In the air, we can determine the sound direction within a few degrees, but in water, there is an up to 90 degrees error margin. This is not so strange, because we are trained to react to the small time differences between the ears, which are due to the speed of sound in air. In water, the speed of sound is four times greater, and the time differences are much smaller,” Jakob Christensen-Dalsgaard explains, concluding, “The results tell us that humans have a reduced ability to determine the direction of sounds underwater, thus confirming that human hearing is not adapted to work well underwater.” Reference: “Is human underwater hearing mediated by bone conduction?” by K.Sørensen, J.Christensen-Dalsgaard and M. Wahlberg, 19 March 2022, Hearing Research. DOI: 10.1016/j.heares.2022.108484
