DNA valve controlling molecular processes along DNA. Credit: Thomas Gorochowski Scientists created DNA valves for controlling cellular processes, using nanopore sequencing for rapid development. This technology opens new avenues for gene regulation and genome editing. Scientists at the University of Bristol have developed new biological parts that are able to shape the flow of cellular processes along DNA. The work, now published in the journal Nature Communications, offers a fresh perspective on how information is encoded in DNA and new tools for building sustainable biotechnologies. Despite being invisible to the naked eye, microorganisms are integral for our survival. They operate using DNA, often referred to as the code of life. DNA encodes numerous tools that could be useful to us, but we currently lack a complete understanding of how to interpret DNA sequences. Challenges in Understanding Microbial DNA Matthew Tarnowski, first author and a PhD student in Bristol’s School of Biological Sciences, said: “Understanding the microbial world is tricky. While reading a microbe’s DNA with a sequencer gives us a window into the underlying code, you still need to read a lot of different DNA sequences to understand how it actually works. It’s a bit like trying to learn a new language, but from only a few small fragments of text.” To tackle this problem, the Bristol team focused on how the information encoded in DNA is read, and specifically, how the flow of cellular processes along DNA are controlled. These biological information flows orchestrate many of the core functions of a cell and an ability to shape them would offer a way to guide cellular behaviors. Inspiration from Nature for DNA Valves Taking inspiration from nature, where it is known that flows on DNA are often complex and interwoven, the team focused on how these flows could be regulated by creating “valves” to tune the flow from one region of DNA to another. Dr. Thomas Gorochowski, senior author and Royal Society University Research Fellow at the University of Bristol, said: “Similar to a valve that controls the rate that a liquid flows through a pipe, these valves shape the flow of molecular processes along DNA. These flows allow cells to make sense of the information stored in their genomes and the ability to control them enables us to reprogram their behaviors in useful ways.” Designing new biological parts can typically take a huge amount of time. To get around this problem, the team employed methods to enable the rapid assembly of many DNA parts in parallel and a sequencing technology based on ‘nanopores’ that allowed them to simultaneously measure how each part worked. Dr. Gorochowski added: “Harnessing the unique features of nanopore sequencing was the step needed to unlock our ability to effectively design the biological valves. Rather than separately building and testing a couple at a time, we could instead assemble and test thousands in a mixed pool, helping us pull apart their design rules and better understand how they work.” Applications and Future Directions The authors go on to further show how valves can be used for regulating other biological components in the cell, opening avenues to the future simultaneous control of many genes and complex editing of genomes. Looking forward, the team are currently considering how this technology could be used responsibly. Dr. Mario Pansera, distinguished researcher of the Post-Growth Innovation Lab at the University of Vigo, Spain, said: “Now that they have crafted these tools, a big question is how they can be used responsibly and equitably in the real world. Post-growth entrepreneurship offers useful approaches for imagining more deliberative and inclusive ways to put such technology at the service of people.” Reference: “Massively parallel characterization of engineered transcript isoforms using direct RNA sequencing” by Matthew J.

Credit: Birchmeier Lab, MDC Three oscillating proteins cause new muscle cells to emerge from muscle stem cells in a balanced manner. In a paper being published in the journal Nature Communications, a team led by MDC researcher Carmen Birchmeier explains in detail how this process works. When a muscle grows, because its owner is still growing or has started exercising regularly, some of the stem cells in this muscle develop into new muscle cells. The same thing happens when an injured muscle starts to heal. At the same time, however, the muscle stem cells must produce further stem cells – i.e., renew themselves – as their supply would otherwise be depleted very quickly. This requires that the cells involved in muscle growth communicate with each other. Muscle Growth Is Regulated by the Notch Signaling Pathway Two years ago, a team of researchers led by Professor Carmen Birchmeier, head of the Developmental Biology/Signal Transduction Lab at the Berlin-based Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC), showed that the development of stem cells into muscle cells is regulated with the help of two proteins, Hes1 and MyoD, which are produced in the progenitor cells in an oscillatory manner – i.e., there are periodic fluctuations in the number of cells produced. Both proteins are involved in the Notch signaling pathway, a widespread mechanism by which cells respond to external stimuli and communicate with other cells. The signaling pathway is named after its receptor “Notch,” onto which the ligand “Delta,” a cell surface protein, latches. A Third Protein, Delta-like1, Plays a Crucial Role “In our current study, we have provided unequivocal evidence that oscillation in muscle tissue is not just some strange phenomenon of the cells involved, but that these rhythmic fluctuations in gene expression are actually crucial for transforming stem cells into muscle cells in a balanced and controlled manner,” says Birchmeier. Together with researchers from Japan and France, Birchmeier and four other scientists at the MDC also uncovered the crucial role of a third protein that, along with Hes1 and MyoD, forms a dynamic network within the cells. As the team reports in the journal Nature Communications, this protein is the Notch ligand Delta-like1, or Dll1 for short. “It is produced in activated muscle stem cells in a periodically fluctuating manner, with the oscillation period lasting two to three hours,” Birchmeier explains, adding: “Whenever a portion of the stem cells expresses more Dll1, the amount in the other cells is correspondingly lower. This rhythmic signaling determines whether a stem cell becomes a new stem cell or develops into a muscle cell.” The Hes1 Protein Sets the Pace in the Stem Cells In their experiments with isolated stem cells, individual muscle fibers, and mice, Birchmeier and her team further investigated how the Hes1 and MyoD proteins are involved in muscle growth. “Put simply, Hes1 acts as the oscillatory pacemaker, while MyoD increases Dll1 expression,” says Dr. Ines Lahmann, a scientist in Birchmeier’s lab and a lead author of the study along with Yao Zhang from the same team. “These findings were demonstrated not only in our experimental analyses, but also in the mathematical models created by Professor Jana Wolf and Dr. Katharina Baum at the MDC,” Birchmeier says. Experiments With Mutant Mice Provided the Decisive Proof With the help of gene-modified mice, the researchers obtained the most important evidence that Dll1 oscillation plays a critical role in regulating the transformation of stem cells into muscle cells. “In these animals, a specific mutation in the Dll1 gene causes production of the protein to occur with a time delay of a few minutes,” Birchmeier explains. “This disrupts the oscillatory production of Dll1 in cell communities, but does not alter the overall amount of the ligand.” “Nevertheless, the mutation has severe consequences on the stem cells, propelling them to prematurely differentiate into muscle cells and fibers,” reports Zhang, who performed a large portion of the experiments. As a result, he says, the stem cells were depleted very quickly, which resulted, among other things, in an injured muscle in the mice’s hind legs regenerating poorly and remaining smaller than it had been before the injury. “Quite obviously, this minimal genetic change manages to disrupt the successful communication – in the form of oscillation – between stem cells,” Zhang says. This Knowledge Could Lead to Better Treatments for Muscle Diseases “Only when Dll1 binds to the Notch receptor in an oscillatory manner and thus periodically initiates the signaling cascade in the stem cells is there a good equilibrium between self-renewal and differentiation in the cells,” Birchmeier concludes. The MDC researcher hopes that a better understanding of muscle regeneration and growth may one day help create more effective treatments for muscle injuries and diseases.

Progesterone-sensitive neurons in the anterior VMH drive sexual rejection in females, depending on their fertility. This discovery sheds light on the brain’s regulation of reproductive behavior. Researchers at the Champalimaud Foundation (CF) have identified a key neural circuit involved in sexual rejection, uncovering a group of brain cells that influence whether a female accepts or rejects mating attempts depending on her reproductive cycle. Published in the journal Neuron, their study provides new insights into how the brain governs social and reproductive behaviors. Female mammals, such as rodents, accept mating attempts only during their fertile phase and actively reject males outside this period. Although the brain regions controlling sexual receptivity are well-studied, the mechanisms underlying active rejection remain less understood. “Sexual rejection isn’t just the absence of receptivity, it’s an active behavior,” explains Susana Lima, senior author and head of the Neuroethology Lab at CF. “Females exhibit defensive actions like running away, kicking, or boxing the male. We wanted to understand how the brain switches between these two drastically different behavioral states.” Central to their research is the ventromedial hypothalamus (VMH), an evolutionarily ancient brain region that controls social and sexual behavior across species, including humans. “We suspected that the VMH might house a separate population of cells dedicated to rejection, based on previous low-resolution imaging experiments showing VMH activity during both acceptance and rejection of male advances,” says Lima. The team focused on the anterior VMH, a less-explored area, particularly on cells responsive to the hormone progesterone, which fluctuates throughout the reproductive cycle. “These neurons are ideal for studying how the female brain toggles between acceptance and rejection during the cycle,” notes first author Nicolas Gutierrez-Castellanos. No. Yes. It Depends. “Understanding this flip gives us insight into how the brain integrates signals from the environment and the body to shape behavior,” continues Gutierrez-Castellanos. “It’s a striking example of how the same stimulus—in this case, an eager male—can elicit completely opposite behaviors, depending on the female’s internal state.” Through advanced techniques like fiber photometry—which tracks real-time brain activity by measuring calcium signals—researchers observed the behavior of these progesterone-sensitive neurons in both receptive and non-receptive female mice during interactions with males. The results were striking: anterior VMH neurons became highly active in non-receptive females, correlating with defensive actions like kicking and boxing, but were far less active in receptive females. Example neuron in the anterior ventromedial hypothalamus (VMH, blue line). Using a technique called “uncaging,” researchers found that inhibitory signals near the center of this neuron (yellow squares) were stronger during the fertile phase of the reproductive cycle. Reduced activity in these cells promotes mating behavior. Credit: Nicolas Gutierrez-Castellanos, Lima Lab, Champalimaud Foundation “It appears that progesterone-responsive neurons in the anterior VMH act as gatekeepers for sexual rejection,” says co-first author Basma Husain. “When a female is outside her fertile window, these neurons become highly active, prompting rejection. But during fertility, their activity decreases, allowing mating to occur.” The Brain’s Dual Control Knobs How do these neurons switch on or off depending on fertility? To investigate, the team performed electrophysiology experiments, measuring the activity of progesterone-responsive neurons in brain slices. “We found that in non-receptive females, these neurons received more excitatory signals, making them more likely to be activated”, explains Gutierrez-Castellanos. “In receptive females, they received more inhibitory signals, reducing their likelihood of firing. It’s a testament to how adaptable and flexible neural connections in the hypothalamus—and the brain—can be.” “The activity levels and excitation/inhibition balance of progesterone-responsive neurons in the anterior VMH strongly suggested their role in sexual rejection,” says Husain. “To confirm this, we used optogenetics to selectively activate these neurons with light.” Indeed, artificially stimulating them during the fertile phase induced rejection behaviors such as kicking and boxing. “It’s like flipping a switch—even though the females were fertile, they acted as if they weren’t.” Conversely, silencing these neurons with a chemical drug in non-receptive females reduced rejection behaviors, though interestingly, it didn’t make them fully receptive—indicating that two distinct populations of neurons, one controlling rejection, and the other receptivity, work in concert to produce the appropriate behavior according to the female’s internal state. “This setup gives the brain two ‘knobs’ to adjust,” Lima explains. “It’s a more efficient and robust way for the brain to balance these behaviors, ensuring mating occurs when conception is most likely, while minimizing the risks and costs of mating, such as exposure to predators or diseases.” Husain adds, “This dual-system likely adds flexibility to the brain’s regulation of sexual behavior. Sex isn’t deterministic. Even during the receptive phase, a female might still reject males, so the ability to draw on both sets of neurons may allow for more nuanced and dynamic behaviors.” Notably, these findings align with recent research showing that progesterone-responsive neurons in the posterior VMH, which drive sexual receptivity, undergo similar cycle-dependent changes, but in the opposite direction—active during the fertile phase and inactive outside it. “The VMH exists in humans and likely plays similar roles”, notes Lima. “Recent studies in mouse models have shown that the VMH changes in pathological conditions like polycystic ovarian syndrome. Additionally, socially isolating female mice during development may lead to reduced sexual receptivity, with alterations in the same brain area, underscoring the VMH’s clinical relevance.” “We’re just beginning to scratch the surface of how the brain’s internal wiring orchestrates social behavior,” concludes Lima. “There’s much more to learn, but these findings bring us a step closer to understanding how neural mechanisms and internal states drive complex social interactions, from sexual behavior to aggression and beyond.” Reference: “A hypothalamic node for the cyclical control of female sexual rejection” by Nicolas Gutierrez-Castellanos, Basma Fatima Anwar Husain, Inês C.
