New research has transformed the understanding of lactate from a perceived waste product to a vital energy source that helps regulate glucose levels and fuels the body during physical activity and rest, debunking old myths about its role in muscle fatigue. Research challenges the common belief among athletes and physicians that high lactate levels are harmful. As a student competing in track and field at his Parlier high school, Robert Leija was obsessed with how to improve his performance and, in particular, prevent the buildup of lactic acid in his muscles during training. Like many athletes, he blamed it for the performance fatigue and muscle soreness he experienced after intense workouts. But as a kinesiology student at Fresno State, he was handed an out-of-print textbook that told him he had it all wrong. Lactate wasn’t a danger sign that athletes had depleted their body’s supply of oxygen, but likely a normal product of the metabolic activity required to fuel the muscles during sustained exercise. Now, as a graduate student in the University of California, Berkeley, laboratory of the scientist who wrote that textbook, George Brooks, his research is providing a much clearer picture of lactate’s role in the body, further refuting the notion that lactate is a sign of oxygen deprivation in the muscles. In a paper published in February in the journal Nature Metabolism, Leija, Brooks, and their colleagues showed conclusively that lactate is produced normally in humans after ingestion of carbohydrates. Lactate rapidly enters the bloodstream, even before glucose shows up. Far from being a toxic byproduct to be eliminated during hard exercise, dietary glucose is converted so rapidly to lactate that it preempts or shares top billing with glucose as the two main carbon-energy carriers in the body. A volunteer is monitored after being given a large dose of glucose to determine how well people switch from fat to carbohydrate metabolism as they age. In the tests at UC Berkeley, subjects had their blood monitored for labeled lactate and glucose, underwent periodic blood sampling, and had their breath monitored for oxygen and carbon dioxide. Credit: Robert Leija, UC Berkeley The results show that the rapid conversion of glucose to lactate, starting initially in the intestines, is a way for the body to deal with a sudden dose of carbohydrates. Lactate, working with insulin, buffers the appearance of dietary glucose in the blood. “Instead of a big glucose surge, we have a lactate and glucose surge after eating,” said Brooks, a UC Berkeley professor of integrative biology. “And the more of it that is converted into lactate from glucose, the better it is to manage glucose. Lactate is a carbohydrate buffer.” Brooks and his colleagues had earlier shown this to be true during intense exercise. The new study confirms that lactate plays the same role during normal non-exercise activity and resting. “It’s evidence to show that lactate shouldn’t be associated with anaerobic metabolism — that is oxygen-limited metabolism. It’s just a normal response to consuming carbohydrates or to exercise,” Leija said. “In exercise, lactate is utilized as the dominant fuel source. That’s why your blood lactate increases as you exercise a little harder. It’s not that you’re making it as a waste product. It’s getting into the blood because it needs to go to tissues that need it to continue their physiological performance.” Glucose tolerance The study was conducted on 15 healthy, physically active young adults — eight women and seven men — as part of a larger NIH-funded study to determine how well people switch from fat to carbohydrate metabolism as they age. The volunteers were asked to fast overnight (12 hours) to deplete their carbohydrate and glycogen stores so that they were getting energy primarily by breaking down fats into fatty acids and using them to power basic bodily functions. They then drank 75 grams of glucose, a rapidly absorbed sugar, to stimulate a switchover from fatty acid to carbohydrate metabolism. This is similar to the glucose tolerance test used to diagnose diabetes and is commonly given to pregnant women to screen for gestational diabetes. Brooks’ study differed from previous similar studies in that he and his colleagues, including Leija, closely monitored the volunteers’ blood lactate levels over a two-hour period following ingestion of the glucose, and periodically measured the ratio of oxygen and carbon dioxide in their breath, which indicates the proportion of fatty acids versus carbohydrates being burned. In order to calculate the amount of lactate that entered the blood compared to glucose, they infused lactate and glucose tracers — lactate labeled with a stable, non-radioactive isotope, carbon-13, and glucose labeled with deuterium — for 90 minutes beforehand to bring the levels of labeled lactate and glucose in the blood to between 1% and 2%. The dilution of the labeled lactate and glucose by incoming, unlabeled dietary glucose allowed them to establish the kinetics, that is, the appearance, disappearance, and clearance of blood lactate and glucose. Most such experiments measure static venous blood concentration, which provides little information about glucose and lactate kinetics. Sampling of arterialized blood was also key to the success of the study, Leija said. That allowed the researchers to see what happened in the gut. Typically, a forearm vein is used to sample blood 30 minutes after a glucose challenge, but that sampling yields muddled results. The researchers found that the volunteers began converting the dietary glucose into lactate before it even left the intestines. Levels of lactate began rising in arterial blood a mere five minutes after the meal, while glucose, often touted as the energy currency of the body, only showed up in the bloodstream 15 to 30 minutes after glucose ingestion. “The first carbohydrate after a glucose meal gets into the blood as lactate because that’s what intestinal cells do and because most of the glucose is captured by the liver before it is released into the blood for the muscles, where glucose is going to be converted to lactate,” Brooks said. “We could see that because of lactate clearance and oxidation and because carbon-13 from the lactate tracer appeared in blood glucose. This shows that lactate is just a major energy highway for distributing carbohydrate — carbon energy flux.” The lactate shuttle Brooks has conducted human and animal studies for more than 50 years to investigate the role of lactate in the body, each study providing more evidence that it’s not a toxic byproduct of oxygen-limited, anaerobic metabolism, which does not happen in the human body, he said. That assumption, however, has colored the way athletes as well as physicians have looked at lactate. Many physicians still perceive high levels of lactate — often incorrectly called lactic acid — in the blood as a symptom of illness that needs to be fixed with supplemental oxygen or drugs. “Measuring lactate is one of the major things that sports medicine practitioners do. And now we understand what’s happening,” Brooks said. “Athletes are producing lactate all the time and clearing it all the time. And when they get to the point where they can’t clear it, mostly by oxidation and making it into glucose, we know the person can’t persist very long. “I think this is so revolutionary. But it’s really confusing to people. What was bad now is good. All the books are wrong.” Except for Brooks’ textbook, “Exercise Physiology: Human Bioenergetics and Its Applications.” Originally written in 1984 with Thomas Fahey, it’s now in its 5th edition. Text for the 6th edition is already being uploaded to the publisher. “When I read through Dr. Brooks’ 1984 book it was a complete mind blow to me, to be honest,” Leija said. “I had always associated lactic acid with exercising so hard that I was running out of oxygen and I wasn’t putting anything together in terms of physiology. Then it started to make a lot more sense.” In his book, Brooks coined the term “lactate shuttle” to describe the body’s metabolic feedback loop in which lactate is the intermediary sustaining most if not all tissues and organs. He has showed, for example, that in many tissues, lactate is preferred as a fuel over glucose. During intense activity, the muscle mitochondria burn it preferentially and even shut off glucose and fatty acid fuel use. Brooks used tracers to show that human skeletal muscle, heart muscle and the brain prefer lactate to glucose as fuel and run more strongly on lactate. Lactate also signals fat tissue to stop breaking down fat for fuel. One gap in these studies was what happens during normal non-exercise activity and resting. The current study fills that gap and supports the idea that when lactate levels in the blood remain high, it is a signal that something is disrupting the lactate shuttle cycle, not that lactate itself is harming the body. “It’s really informative about various medical conditions,” Brooks said. “I think what’s significant about the current result is that it’s just not a muscle thing. It starts with dietary carbohydrate. This was a missing piece in the puzzle.” The recent study is part of Leija’s Ph.D. thesis, after which he hopes to conduct further research on the metabolic role of lactate. “Since before college I would read physiology books trying to improve my training and I would see all these science terms that I kind of ignored back then because I was just looking for, How can I get faster? How can I run longer?” Leija said. “But now, wow, it ended up helping me out indirectly. Still to this day, there’s so much I think that’s left to be uncovered about it.” Reference: “Enteric and systemic postprandial lactate shuttle phases and dietary carbohydrate carbon flow in humans” by Robert G.

In mice deficient in USAG-1, an antagonist of BMP, the trace deciduous incisors survive and erupt as excess teeth. Credit: Kyoto University/Katsu Takahashi Antibody for USAG-1 shown to stimulate tooth growth. The tooth fairy is a welcome guest for any child who has lost a tooth. Not only will the fairy leave a small gift under the pillow, but the child can be assured of a new tooth in a few months. The same cannot be said of adults who have lost their teeth. A new study by scientists at Kyoto University and the University of Fukui, however, may offer some hope. The team reports that an antibody for one gene — uterine sensitization associated gene-1 or USAG-1 — can stimulate tooth growth in mice suffering from tooth agenesis, a congenital condition. The paper was published in Science Advances. Although the normal adult mouth has 32 teeth, about 1% of the population has more or fewer due to congenital conditions. Scientists have explored the genetic causes for cases having too many teeth as clues for regenerating teeth in adults. According to Katsu Takahashi, one of the lead authors of the study and a senior lecturer at the Kyoto University Graduate School of Medicine, the fundamental molecules responsible for tooth development have already been identified. “The morphogenesis of individual teeth depends on the interactions of several molecules including BMP, or bone morphogenetic protein, and Wnt signaling,” says Takahashi. BMP and Wnt are involved in much more than tooth development. They modulate the growth of multiple organs and tissues well before the human body is even the size of a raisin. Consequently, drugs that directly affect their activity are commonly avoided, since side effects could affect the entire body. Guessing that targeting the factors that antagonize BMP and Wnt specifically in tooth development could be safer, the team considered the gene USAG-1. “We knew that suppressing USAG-1 benefits tooth growth. What we did not know was whether it would be enough,” adds Takahashi. The scientists therefore investigated the effects of several monoclonal antibodies for USAG-1. Monoclonal antibodies are commonly used to treat cancers, arthritis, and vaccine development. USAG-1 interacts with both BMP and Wnt. As a result, several of the antibodies led to poor birth and survival rates of the mice, affirming the importance of both BMP and Wnt on whole body growth. One promising antibody, however, disrupted the interaction of USAG-1 with BMP only. Experiments with this antibody revealed that BMP signaling is essential for determining the number of teeth in mice. Moreover, a single administration was enough to generate a whole tooth. Subsequent experiments showed the same benefits in ferrets. “Ferrets are diphyodont animals with similar dental patterns to humans. Our next plan is to test the antibodies on other animals such as pigs and dogs,” explains Takahashi. The study is the first to show the benefits of monoclonal antibodies on tooth regeneration and provides a new therapeutic framework for a clinical problem that can currently only be resolved with implants and other artificial measures. “Conventional tissue engineering is not suitable for tooth regeneration. Our study shows that cell-free molecular therapy is effective for a wide range of congenital tooth agenesis,” concludes Manabu Sugai of the University of Fukui, another author of the study.

A frog and a tarantula make good housemates. Credit: Francesco Tomasinelli & Emanuel Biggi Tarantulas interact beneficially with many species, using their hair as a defense against predators. New findings suggest they may also use chemical secretions for protection. An international team of researchers has discovered new insights into the mutually beneficial ecological relationships and evolutionary adaptations of tarantulas. In their study, the team conducted an extensive review of literature and studied how tarantulas interact with various other species. The study is the first to report an association between tarantulas and snakes, whip spiders, and harvestmen, and it also identified over 60 new cases of partnerships between tarantulas and amphibians across ten different countries.

Credit: Delwin Eggers Mutual Benefits of Coexistence According to the researchers, the interaction, or even cohabitation, between the tarantulas and other species is often mutually beneficial. First author and researcher Alireza Zamani from the University of Turku, Finland says: “Apparently, the frogs and toads that live within the retreats of tarantulas benefit from the shelter and protection against their predators. In turn, they feed on insects that could be harmful to the spider, its eggs, and its juveniles. It seems that tarantulas might not be as scary and threatening as their reputation suggests.” One of the most significant findings of this study is the proposal of a new hypothesis on why tarantulas are so hairy. The researchers believe that the hirsuteness – or hairiness – of tarantulas may have evolved as a defense mechanism against predatory ants. Defence Mechanisms of Tarantulas “Observations indicate that army ants tend to ignore both adult tarantulas and spiderlings. This is quite interesting, since army ants are known to attack and feed on a wide variety of arthropods,” says Zamani. In their interactions with tarantulas, the ants were observed to enter the tarantula’s burrow, gather food remains, and clean the burrow, which is beneficial for the tarantula. Only a few ants attempted to attack the spider. However, these attempts failed because the spider’s legs were protected by a fringe of stiff hairs. Small spiderlings in a tarantula burrow and ants not being interested in the spiders. Credit: Witold Lapinski “The dense hair covering the tarantula’s body makes it difficult for the ants to bite or sting the spider. Therefore, we believe that the hairiness may have evolved as a defense mechanism. This hypothesis is supported by findings that many burrowing New World tarantulas cover their egg sacs with urticating hairs. The tarantulas typically release these barbed hairs as a defense mechanism, deterring and sometimes even killing their attackers. Covering their egg sacs with these hairs, however, effectively hinders the movement of small injurious arthropods, such as ants, that might try to attack the eggs,” explains Zamani. Avicularia hirschii tarantula escapes from army ants by hanging from a leaf. Credit: Emanuele Biggi Evolutionary Strategies and Future Research However, the authors suggest that the hirsuteness could be an evolving character unique to certain tarantula species. Those species that have less dense body hair are left more vulnerable to attacks from predatory ants. The researchers documented a unique escape strategy employed by New World arboreal tarantulas when threatened by ants. “In a field study in Peru, a female Avicularia hirschii was observed leaving its silken retreat and hanging from the edge of a leaf by the tips of its front legs after sensing the approach of army ants in search of live prey,” says Zamani. According to the authors, tarantulas may also have another defense strategy involving a previously unknown chemical mechanism. The researchers suggest that the spiders may have specialized epidermal glands in their cuticles that could secrete predator-repellent substances. “This hypothesis is supported by the observation that cats and dogs, animals with highly developed sense of smell, tend to wince and move away after sniffing a tarantula. Tarantulas have slit-like epidermal gland openings of unknown function, which may produce defensive secretions responsible for this reaction,” says Zamani. Although further evidence is needed to substantiate the hypothesis of the chemical defense mechanism, this study marks a significant step forward in understanding the behavior and the evolutionary strategies of tarantulas.
