Researchers David Page and Adrianna San Roman discovered that human sex chromosomes, particularly the gene pair ZFX and ZFY, regulate a wide range of genes throughout the body. Their findings, which redefine the roles of the X and Y chromosomes, suggest these chromosomes are crucial regulators of gene expression beyond just determining sex. Credit: SciTechDaily.com A groundbreaking study reveals that sex chromosomes, especially through genes ZFX and ZFY, play a critical role in regulating gene expression across the human body, challenging traditional views of their function. Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes diverged to become two different chromosomes, X and Y. Even though X and Y have grown apart from each other and taken on unique functions—namely, determining sex and driving sex differences in males and females—they also retain shared functions inherited from their common ancestor. Groundbreaking Research on Gene Regulation New research from Whitehead Institute Member David Page, who is also a professor of biology at the Massachusetts Institute of Technology and a Howard Hughes Medical Investigator, and postdoc in his lab Adrianna San Roman sheds light on the sex chromosomes’ shared role as influential gene regulators. The research, published in the journal Cell Genomics on December 13, shows that genes expressed from the X and Y chromosomes impact cells throughout the body—not just in the reproductive system—by dialing up or down the expression of thousands of genes found on other chromosomes.

This suggests that ZFX and ZFY inherited their role as influential gene regulators from their shared ancestor and have independently maintained it, even as their respective chromosomes diverged, because that regulatory role is critical for human growth and development. The genes regulated by ZFX and ZFY are involved in all sorts of important biological processes, showing that the sex chromosomes contribute widely to functions beyond those related to sex characteristics. Impact of Sex Chromosomes on Global Gene Expression Page and San Roman measured how X and Y chromosomes affected global gene expression by graphing how each gene’s expression changed in cells depending on the number of X or Y chromosomes present. For this work, they used tissue samples from people who naturally have variation in their number of sex chromosomes: people born with anywhere from one to four X chromosomes and zero to four Y chromosomes. These sex chromosome variations are found throughout the human population, and they lead to a variety of health disorders but—unlike duplications of most other chromosomes—are compatible with life. “By using the natural variation of sex chromosome composition in the human population, we were able to mathematically model how the number of X and Y chromosomes impacts expression of genes in a way that’s never been done before. By taking this approach, we gained new insights into the massive impact that X and Y genes have broadly throughout the genome.” San Roman says. For this project, the researchers looked at two cell types that they chose for the ease of sample acquisition – lymphoblastoid cells, a type of immune cell, and skin-cell derived fibroblasts, which help form our connective tissues – and measured how gene expression changed in each cell type with each additional X or Y. They found that thousands of genes changed their expression levels in response to changes in the number of X and/or Y chromosomes present. The effects scaled linearly, meaning that each additional X or Y chromosome changed gene expression by the same amount. Which genes were affected, and by how much, were different for each of the cell types, suggesting that each type of cell in the body may have a unique response to gene regulation by X and Y chromosome genes. By taking this approach, we gained new insights into the massive impact that X and Y genes have broadly throughout the genome.” San Roman says. Unveiling Surprising Similarities and Differences in Gene Regulation However, for a given gene in a given cell type, the effect of an additional X tended to be similar to the effect of an additional Y. This was a surprising finding for the researchers, who had expected that differences in how genes on X and Y regulate other genes might help to explain some of the sex differences that are seen in health and disease. Males and females have, for example, different risks of developing certain diseases, different symptoms upon developing the same disease, and different reactions to certain medicines. There are many differences between male and female cells that are not yet explained, and gene regulators on X and Y that are tweaking gene expression throughout the body seem like promising candidates to be contributing to these differences. Instead, Page and San Roman narrowed in on the gene pair ZFX and ZFY as being responsible for about half of the effect of X and Y on widespread gene expression, and the pair appear to be functionally equivalent–although ZFX sometimes had a modestly stronger effect than ZFY. Other genes on X and Y are likely to be widespread gene regulators as well, making up the other half of the effect. These other gene regulators may, like ZFX and ZFY, be X-Y pairs that play essentially equivalent roles. After all, gene regulation is an important function, and the regulatory roles that X and Y inherited from their shared ancestor may need to be carried out in precisely the same way for fetal viability, regardless of how else X and Y grow apart. However, the researchers suspect that some X and Y genes must modify gene expression in different ways from each other, or to different degrees, in order to explain the many sex differences seen in male and female cells. The challenge is that, because the strongest effect of X and Y on widespread gene expression is shared, it will be harder for researchers to tease out the ways in which the two chromosomes affect gene expression differently. “The effects on the genome that may explain sex differences are more subtle than we had previously predicted,” San Roman says. “One point of interest for future study is that although we saw that X and Y had highly correlated effects on gene expression, we observed larger effects with X as opposed to Y copy number, and this may contribute to sex differences.” Rethinking Sex Chromosomes: Inactive Versus Active X A subtlety thus far not discussed is that when Page and San Roman think about the sex chromosomes, they no longer think of X as most people think of it. Their work has convinced them that our current understanding of the sex chromosomes is imprecise. Although the human sex chromosomes are defined as X and Y, in fact there are two types of X chromosomes, and only one of them differs between typical males and females. Every human in the world has one “active X” chromosome. This chromosome is, like an autosome, universally present and so its presence has no bearing on sex. What differs between typical males and females is the chromosome that pairs with the active X: typical males have a Y chromosome and typical females have an “inactive X” chromosome, which is genetically identical to the active X but has the majority of its genes turned off. In people who have atypical compositions of sex chromosomes, any additional X chromosomes will always be inactive X chromosomes—so when the researchers measured the effect of adding more X chromosomes, they were actually measuring the effect of adding more inactive X chromosomes. The inactive X and the Y, rather than the X and Y, are more accurately the sex chromosomes that the researchers found to be modifying widespread gene expression. Furthermore, Page and San Roman found that the inactive X and the Y both regulate the expression of many genes on the active X chromosome, just as they do on all of the autosomes. (This expands on previous work from Page and San Roman that focused on the relationship between the inactive and active X.) In summary, the active X chromosome behaves like an autosome, while the inactive X chromosome and the Y chromosome function as two sides of the same coin, both as sex chromosomes and as gene regulators. “These chromosomes have historically been known as the ‘inactive’ X and the ‘gene-poor’ Y chromosomes, and given little attention beyond how they contribute to sex differentiation, so it was stunning to us to see how wide their network of influence was,” Page says. “These chromosomes contain genes like ZFX and ZFY that are global gene regulators, and I think as we learn more about them, it’s going to completely change how we think about the genetics of the human X and Y chromosomes.” Reference: “The human Y and inactive X chromosomes similarly modulate autosomal gene expression” by Adrianna K.

Credit: Christina Painting, CC BY-SA 4.0 Nepalese craftsman, Chandra Bahadur Dangi, holds the record as the world’s shortest adult, at 54.6 cm (1 ft 9 ½ inches). The tallest human is Sultan Kösen, a Turkish farmer, almost five times taller at 2.52 meters (8 feet 3 ¼ inches). In nature, size differences among males of a single species are not uncommon, but in a new paper, a team from the Smithsonian Tropical Research Institute (STRI), The University of Auckland and the University of Arizona, discovered a case of male beetles that are not only extremely different in size, but also provide an answer to a long-standing puzzle in evolutionary biology: how can larger animals afford the energetic cost of making and maintaining disproportionately large weapons? Almost one in every four species in the world is a beetle: about 350,000 beetle species have been identified so far. Male New Zealand giraffe weevils, Lasiorhynchus barbicornis, were known to be the longest beetles in the world, but when researchers measured the differences in the weight of the smallest and largest beetles, they were in for a surprise: “When I first saw the weights of the smallest and largest males, I thought someone had made a mistake,” said Ummat Somjee, Earl S. Tupper fellow at STRI. “But we weighed them again and got the same results. The largest males are 30 times larger than the smallest ones. This is the biggest adult size-range we know of any beetle species in the world.” And like many other animals with fighting weapons (like elephants with tusks and antelopes with horns), the big males have snouts that are disproportionately larger than the snouts of tiny males. A big male lords over a female as she lays an egg, using his extra-long snout as a lance to fend off rivals as he fertilizes her. But as massive males vie for position above, one of the smallest males may be sneaking in underfoot to fertilize the female. Because both of these mating strategies result in offspring, both large and small males persist. In tropical forests, every bit of energy expenditure may mean the difference between life and death. Somjee is fascinated by the economics of energy—and looks to insects for inspiration. The male giraffe weevils, literally embody energetic trade-offs. The snouts of big males are disproportionately larger than the snouts of their smaller counterparts: so at first glance it seems that big males invest relatively more materials and energy in their weapons than smaller males. But is this really the case? Somjee teamed up with Chrissie Painting, now senior lecturer at the University of Waikato and local expert on these beetles in New Zealand, to take a closer look at the economics of beetle weaponry. To measure how much energy large and small males use they placed them each in little chambers and measured their oxygen consumption. They found that larger males pay lower, not higher, costs—in terms of energy—per gram of tissue in their bodies compared to smaller ones. How do these large males carry relatively larger weapons, and still pay lower relative metabolic costs?  A large male L. barbicornis guards a female drilling an egg-laying hole, demonstrating the extreme sexual dimorphism in this species.

Painting, CC BY 3.0 “The big males are like very fuel–efficient cars—the Prius of the beetle world (58 miles per gallon)—and the small ones are more like Rolls Royce Phantom Coupes (14 miles per gallon). How can large males be so energy efficient and still bear the additional energy costs of a larger weapon?” Somjee said. The secret, they discovered, lies in the architecture of the weapon itself. Small snouts are made up of a high proportion of living tissue, which is relatively more expensive to maintain—like our muscles—but big snouts are made of a higher proportion of cuticle—like the keratin in our hair and fingernails, which is much cheaper to maintain. So the big males are actually using less energy to maintain their disproportionately big weapons than the small males are using to maintain their small weapons. The finding that large individuals often carry disproportionately large weapons has been a puzzle in biology for almost a century. These bizarre weevils demonstrate that large animals can cut the costs of large structures. Now Ummat is back in Panama looking for other insect species to find out if other insects with extreme structures also find creative ways to minimize their maintenance costs. “It is precisely because of the Giraffe weevils unusually large size variation that we were able to answer this long-standing evolutionary question,” Somjee said. “Giraffe weevils don’t somehow find extra energy to sustain their giant heads, they change the architecture of their heads to make them more efficient and thus save energy.” Reference: “Exaggerated sexually selected weapons maintained with disproportionately low metabolic costs in a single species with extreme size variation” by Ummat Somjee, Erin C.

Aging clocks, which measure biological age with precision, can deviate from chronological age due to environmental influences like smoking or diet. Researchers at the University of Cologne found that these clocks actually track increasing random cellular changes, suggesting that biological aging could be influenced by stochastic variations in processes like DNA methylation and gene activity. Aging clocks can accurately determine a person’s biological age, which can differ from their chronological age—the age calculated from their date of birth—due to environmental influences like diet or smoking. The precision of these clocks indicates that the aging process follows a program. Scientists David Meyer and Professor Dr. Björn Schumacher at CECAD, the Cluster of Excellence Cellular Stress Responses in Aging-Associated Diseases of the University of Cologne, have now discovered that aging clocks actually measure the increase in stochastic changes in cells. The study was recently published published in Nature Aging. “Aging is triggered when the building blocks in our cells become damaged. Where this damage occurs is for the most part random. Our work combines the accuracy of aging clocks with the accumulation of entirely stochastic changes in our cells,” said Professor Schumacher. Fewer Checks, More Noise With increasing age, controlling the processes that occur in our cells becomes less effective, resulting in more stochastic results. This is particularly evident in the accumulation of stochastic changes in DNA methylation. Methylation refers to the chemical changes that affect DNA, the genome’s building blocks. These methylation processes are strictly regulated within the body. However, during the course of one’s life, random changes occur in the methylation patterns. The accumulation of variation is a highly accurate indicator of a person’s age. The loss of control over the cells and the increase in stochastic variation are not restricted to DNA methylation. Meyer and Schumacher demonstrate that the increase in stochastic variations also in gene activity can be used as an aging clock. “In principle it would be feasible to take this even further, allowing the stochastic variations in any process in the cell to predict age,” Schumacher said. According to the authors, it is above all crucial to ascertain if such aging clocks can show the success of interventions that slow the aging process or harmful factors that accelerate aging. Using the available datasets, the scientists showed that smoking increases the random changes in humans and that ‘anti-aging’ interventions such as lower calorie intake in mice reduce the variation in methylation patterns. They also showed that the stochastic noise is even reversible by means of reprogramming body cells to stem cells. The scientists compared human fibroblasts from the skin that were reprogrammed into stem cells and as a result of the reprogramming are rejuvenating. The high variation indicative of the age of the body cells was indeed reversed to the low stochastic noise of young stem cells. Meyer and Schumacher hope that their findings on the loss of regulation and the accumulating stochastic variations will lead to new interventions that can tackle the root cause of aging and may even lead to cellular rejuvenation. A target for such interventions could be repairing stochastic changes in DNA or improved control of gene expression. Reference: “Aging clocks based on accumulating stochastic variation” by David H. Meyer, and Björn Schumacher, 9 May 2024, Nature Aging. DOI: 10.1038/s43587-024-00619-x
