A research team discovered that leucine prevents the degradation of specific mitochondrial proteins, enabling efficient energy production. This mechanism allows cells to adapt to increased energy demands during periods of nutrient abundance.
Researchers at Salk Institute discover a new microprotein, SLC35A4-MP, that regulates mitochondrial structure and function in brown fat tissue. The study reveals the microprotein's role in maintaining healthy cellular metabolism and regulating body temperature.
Researchers at Sanford Burnham Prebys found that blocking macropinocytosis reshapes the tumor microenvironment, allowing more access to immune cells. This change made immunotherapy and chemotherapy more effective in treating PDAC tumors in mice.
A groundbreaking study published in Science Signaling has identified protein tyrosine phosphatase PTP1B as a key driver of maladaptive cardiac metabolism and dysfunction under dietary stress. Mice lacking PTP1B in cardiomyocytes were resistant to harmful changes, highlighting the enzyme's role in heart disease progression.
Researchers found that neurons have a built-in 'backup battery' in the form of stored glycogen, which helps them function during periods of metabolic stress. This discovery challenges traditional views on brain energy metabolism and opens new avenues for exploring treatments for neurological conditions.
Dr. Randy J. Nelson's research reveals that artificial light exposure disrupts immune function, causes neuroinflammation, and influences mood regulation. His work has significant implications for understanding depression and anxiety disorders, as well as the obesity epidemic.
A new study from the Buck Institute has uncovered how breaking down glycogen in neurons may protect against toxic protein buildup and degeneration. Researchers found that restoring an enzyme called glycogen phosphorylase can reduce tau-related damage and improve oxidative stress reduction.
Creatine has broad health benefits beyond athletic performance, including maintaining energy in stressed cells and preventing muscle loss with aging. Studies have shown no significant side effects from creatine supplementation, contradicting common misconceptions.
Researchers have discovered a novel cell-clearance pathway linked to diseases such as Chediak-Higashi Syndrome, which affects immune system function. The study used CRISPR/Cas9 gene-editing technology and live imaging to characterize this pathway and identify key genes involved.
A recent study found that women are more metabolically efficient under extreme conditions, closing the performance gap with men. Women's greater fat mass may contribute to this advantage, enabling them to complete longer distances without burning out.
A new study has identified novel strains of microbes that have adapted to use limited resources in cities, including those found in Hong Kong's subways and skin. These microbes can metabolize manufactured products, posing health risks if they are pathogenic.
Researchers found that switching fruit flies to a low-calorie diet extends their lifespan, even in old age. This study suggests that obese humans may benefit from reducing calorie intake in old age, as it can dramatically change their metabolisms and extend their lives.
Autophagy helps protect cardiomyocytes from damage caused by anthracycline drugs like Doxorubicin. The study found that a protein regulator called ER-phagy alleviates Dox-induced cardiomyopathy, promoting cell survival.
A recent study by researchers at UNICAMP found that low-load with many repetitions and high-load with fewer repetitions both promote similar muscle growth. Muscle activation patterns were different, but metabolic stress was the same in both groups.
Researchers uncover the critical link between cellular energy levels and mitochondrial damage through protein FNIP1. The study reveals that FNIP1 enables communication between AMPK and TFEB, instructing genes to remove damaged mitochondria and create new ones.
Scientists at the University of Utah Health have discovered a complex network of protein-metabolite interactions within cells that enable them to respond to environmental cues and maintain homeostasis. The study, published in Science, highlights the importance of these interactions in regulating metabolic processes and preventing disease.
A hormone called FGF21 protects mice from ethanol-induced loss of balance and righting reflex by activating a specific part of the brain that controls alertness. The study reveals that higher FGF21 concentrations can dramatically accelerate recovery from intoxication.
Diabetes-resistant mice develop a protective beta cell cluster with reduced glucose uptake and increased beta cell division, while diabetic-prone mice experience metabolic stress and beta cell failure. This study reveals the key role of adaptive gene expression in protecting against type 2 diabetes.
Researchers from Juntendo University developed a vaccine targeting senescent cells using glycoprotein nonmetastatic melanoma protein B (GPNMB). The vaccine showed significant improvements in mice with age-related diseases, including atherosclerosis and progeria. This breakthrough has exciting potential for new anti-aging therapies.
Researchers found that IL-1β increases insulin levels in healthy human islets. In contrast, islets from obese individuals with type 2 diabetes were not responsive to IL-1β stimulation. The study suggests that IL-1R signaling plays a crucial role in glucose homeostasis.
Studies suggest that maintaining a normal level of the protein SirT1 may be effective in preventing obesity- and age-related diseases. Researchers have demonstrated that changing three amino acids on SirT1 can produce a 'super-sirt' that functions normally despite metabolic stress.
A new study found that formula-fed rhesus monkeys experienced metabolic stress, similar to those who were breastfed, which may explain the link between early feeding practices and chronic diseases. Reducing protein content in infant formula could be beneficial in reducing metabolic stress.
A new study found that metabolic stress can increase the onset of atrial arrhythmias, such as atrial fibrillation, by activating KATP channels in the atria. Blocking these channels with anti-diabetic drugs reversed the effects of metabolic stress and prevented atrial arrhythmia induction.
A new method, metabolic stress disinfection (MSDD), sucks the life out of bugs by subjecting them to alternating vacuum and carbon dioxide, effectively suffocating organisms. The technique could replace post-harvest pesticides and may complete phasing out ozone-depleting methyl bromide, reducing chemical costs and environmental impact.
