A new method has been developed to link individual microbes to their genetic code, providing insights into the activity of microorganisms in coastal sediments. The study reveals a diverse microbial community thriving in environments subject to frequent disruptions from rapid temperature changes and tides.
Researchers developed a new method to link genetics and function of individual microbes living without oxygen deep below Earth's surface. The approach enabled discovery of the most active organism in a Death Valley groundwater aquifer, expanding its application to low biomass environments.
A study by researchers from Japan has revealed that cysteine persulfide, produced by cysteinyl-tRNA synthetase, regulates cellular longevity in budding yeast. The study found that introducing supersulfides can reverse detrimental effects on mitochondrial energy metabolism and protein quality.
Chicken sperm can retain fertility and viability for up to three weeks after refrigeration, making it unsuitable for traditional cryopreservation methods. The study found that removing calcium ions impacts energy metabolism dynamics, inducing a physiological dormancy-like state in the sperm cells.
Researchers have found that mouse stem cells mimic their parent animals' cold resistance, generating energy differently at low temperatures. This discovery opens up new avenues for studying organ preservation and human hibernation using in vitro models.
Researchers discovered that FDA-approved HDAC-inhibitors can impact energy metabolism in solid tumor cells, including glioblastoma. The combination of HDAC-inhibitors and imipridones may synergize to enhance killing of GBM cells by reversing cellular respiration.
A massive supercomplex in mitochondria comprising all four respiratory complexes induces a membrane curvature necessary for proper mitochondrial function. The supercomplex assembly actively contributes to the shaping of the macroscopic architecture of mitochondria.
A new study reveals that only a small fraction of marine microorganisms consume oxygen and release carbon dioxide, with less than three percent accounting for up to a third of the process. This discovery has significant implications for our understanding of the ocean's carbon cycle.
A study found that endurance exercise improves mitochondrial respiration in skeletal muscles but has no impact on adipose tissue. This difference affects insulin sensitivity, with women showing higher cellular respiration in adipose tissue than men.
A subset of immune cells from PID patients exhibit increased cellular respiration, leading to inflammation and autoimmunity. Researchers successfully administered a targeted treatment with fewer side effects.
A team at Harvard's Wyss Institute discovered that bacteriostatic antibiotics slow down oxygen consumption, reducing cellular respiration and making bacteria tolerant. This can explain why certain antibiotic therapies fail. The findings provide a new strategy for developing urgently needed therapeutics.
Researchers at Karolinska Institutet discovered unstable proteins cause premature ageing by impairing cell respiration. Changes in mtDNA introduce errors into mitochondrial proteins, leading to their instability and breakdown.
Researchers at Karolinska Institutet have discovered a new function for a protein essential to mitochondrial protein synthesis, which plays a key part in cell respiration. Without this protein, mitochondria cannot produce proteins and cellular respiration is impaired.
