A groundbreaking study led by Guadalupe Sabio from the National Cancer Research Center (CNIO) and cintia Folgueira from the CNIO and the national Center for Cardiovascular Research (CNIC) has uncovered a novel mechanism by which brown fat burns calories to generate heat. Published in Nature Communications, the research highlights the pivotal role of a protein called MCJ, opening new avenues for combating obesity, a global health crisis affecting 650 million people and linked to metabolic disorders, cardiovascular diseases, and even cancer [1].
The Dual Nature of Fat: White vs. Brown
fat in the human body serves as an energy reservoir, storing calories primarily in white adipose tissue, the familiar fat found beneath the skin. Though, most mammals, including humans, possess a second type of fat known as brown fat, which burns calories to produce heat in response to cold temperatures. While brown fat is abundant in babies, it was once thought to be nearly absent in adults. Recent discoveries, though, have revealed its presence in adults, making it a prime target for anti-obesity research [2].
the brown color of this fat stems from its high concentration of mitochondria, the cellular powerhouses responsible for converting oxygen into metabolic energy. within brown fat, mitochondria contain a unique protein called thermogenin (UCP1), which enables them to burn fat and generate heat—a process known as thermogenesis. This mechanism is crucial for maintaining body temperature in cold environments [3].
MCJ: A New Player in Fat Metabolism
While UCP1 has long been the focus of obesity research, Sabio and Folgueira’s team discovered an option heat-generating process in brown fat, independent of UCP1 and regulated by the MCJ protein.Previously identified as a repressor of mitochondrial function in tissues like the liver, MCJ’s absence was found to accelerate metabolism.The researchers observed that MCJ levels in human subcutaneous fat correlate with metabolic health.Subcutaneous fat, which constitutes 90% of the body’s fat, also contains beige fat, which behaves similarly to brown fat. By eliminating MCJ in obese mice, the team observed meaningful weight loss and increased heat production. ”The mitochondria where eating fat and glucose, burning everything that came to them,” Sabio explained.
implications for Obesity Treatment
The study’s findings suggest that targeting MCJ could offer a novel approach to obesity treatment. By transplanting fat lacking MCJ into obese mice, researchers achieved weight reduction, demonstrating the protein’s potential as a therapeutic target. This breakthrough could pave the way for innovative treatments that enhance the body’s ability to burn fat, offering hope to millions struggling with obesity and its associated health risks.

Lose MCJ to Lose Weight: A Breakthrough in Obesity Research
Obesity, declared by the world Health Association as a global pandemic, continues to challenge public health systems worldwide. But a groundbreaking discovery involving the protein MCJ (Mitochondrial Carrier Homolog 2) could pave the way for innovative treatments. Researchers have found that eliminating MCJ in brown adipose tissue (BAT) triggers a thermogenic response, mimicking the effects of cold exposure and perhaps aiding weight loss.
The study, published in Nature Communications, reveals that MCJ acts as a brake on mitochondrial activity in brown fat. By removing this protein, mitochondria are tricked into behaving as if they are cold, even in normal conditions. “Mitochondria believe they are cold when in reality they are not,” explains lead researcher Beatriz Cicuéndez. This discovery positions MCJ as a promising therapeutic target in the fight against obesity.
The Science Behind MCJ and Brown Fat
brown adipose tissue, ofen referred to as “good fat,” is unique in its ability to generate heat by burning calories. Unlike white fat, which stores energy, brown fat is metabolically active and plays a crucial role in regulating body temperature. The study found that eliminating MCJ enhances this thermogenic process,effectively turning brown fat into a calorie-burning powerhouse.
In experiments with mice, researchers used a modified adenoassociated virus—a tool commonly employed in gene therapies—to silence MCJ. The results were striking: mice without MCJ exhibited increased energy expenditure and reduced fat accumulation.
Challenges and Opportunities
while the findings are promising, translating them into human therapies presents significant challenges. One major hurdle is ensuring that MCJ elimination does not cause harmful side effects. MCJ is present in various tissues, and altering its function could inadvertently impact other organs.However, researchers are optimistic. “What is already known about MCJ suggests that its elimination is also beneficial for the liver and heart,” notes Sabio, a key figure in the study.
Another challenge is developing a targeted delivery method for humans. Sabio believes that nanoparticles could be the solution. “This would concentrate the effect where it matters to maximize its action and not dilute it,” he explains.
The Road Ahead
The discovery of MCJ’s role in brown fat thermogenesis opens new avenues for obesity research. “Discovering new mechanisms of heat production in brown fat is one of the most interesting targets in the study of obesity,” Sabio concludes.
As the scientific community continues to explore this breakthrough, the potential for developing safe and effective obesity treatments grows. With obesity rates soaring globally, the need for innovative solutions has never been more urgent.
