Senescent cells can cause chronic inflammation through the secretion of inflammatory molecules, leading to age-related diseases. The study found that a cellular circuit controlling DNA repair can suppress this inflammation, offering potential ways to promote healthier aging.
A new study reveals a link between senescent cells and the protein HIRA, which helps pack and unpack DNA. The research team discovered that HIRA is necessary for the cells to begin emitting inflammatory molecules, leading to chronic inflammation in the body.
Researchers at the University of Toronto have discovered a DNA repair mechanism that uses nuclear metamorphosis to fix double-strand breaks in human cells. This discovery has significant implications for cancer treatment and premature aging, and may lead to new therapeutic avenues.
A team of researchers from Ritsumeikan University in Japan has elucidated the mechanism behind the liquid-solid phase transition of FUS protein that leads to ALS. They discovered a new therapeutic target, arginine, which suppresses FUS aggregation and could delay ALS progression.
Scientists have discovered the orf137 gene responsible for male sterility in tomato plants, enabling the development of an efficient F1 hybrid breeding system. The study also demonstrates targeted mutagenesis and homologous recombination mechanisms underlying this trait.
Researchers have discovered toxic DNA buildup in the eyes of patients with geographic atrophy, a devastating form of age-related macular degeneration. Common HIV drugs or safer alternatives, such as Kamuvudines, may block inflammation and protect against retinal cell death, offering new hope for treatment.
The innate immune system interprets cytosolic DNA as a sign of intracellular pathogens. However, cGAS is found in the nucleus and prevents autoimmune reactions by binding to chromatin, not DNA. This interaction fails to activate the innate immune system.
A newly discovered molecular pathway involving topoisomerase 1 (TOP1) enables the detection of DNA in the cytoplasm, triggering inflammation and cellular senescence. This pathway may be targeted to enhance the response of cancer cells to immune checkpoint blockade therapy.
Researchers at LMU's Gene Center found that human cells use a different mechanism to recognize misplaced DNA than mouse cells. The inflammasome complex is activated via the cGAS-STING recognition mechanism, triggering both an antiviral response and a classical inflammatory reaction.
Researchers found that cytoplasmic DNA can accumulate beneficial substitutions faster than free-living sexual genomes. Cytoplasmic genomes, including mitochondria and plastids, undergo adaptation due to uniparental inheritance and egg cell selection against faulty mitochondria.
Researchers have identified a snitch that reveals cancer cells to the immune system by producing interferon, activating macrophages and T cells to kill cancer cells. MUS81 enzyme plays a crucial role in this process, triggering an immune response in cancer cells.
Researchers at UT Southwestern Medical Center identified a new enzyme, cyclic GMP-AMP synthase (cGAS), that acts as an innate immunity sensor. The discovery sheds light on the mechanism underlying immune responses to foreign DNA and may lead to new treatments for autoimmune diseases.
Researchers at Thomas Jefferson University discovered a key protein component involved in inflammation detection and reaction to cytoplasmic DNA produced by infections or tissue damage. AIM2, a tumor suppressor, induces cell death to prevent pathogen replication.
Researchers have discovered a significant link between low birth weight and mitochondrial DNA passed from mothers to offspring. This finding suggests that genetics play a substantial role in determining birth weight, and may also contribute to adult illnesses such as diabetes and heart disease.
A team of scientists from the University of Illinois at Chicago has discovered a molecular motor called myosin-1 in the nucleus, where it powers the assembly line that forges RNA messages off DNA templates. This finding offers insight into the DNA transcription process and may lead to new ways to treat cancers and other diseases.
Researchers have observed RNAP molecules possessing intrinsic transcription rates and propensities to pause and stop. The study provides new insights into how genetic expression in cells may be regulated, suggesting a kinetic competition between transcription and pausing.
A research team has discovered a key gene in the human telomerase enzyme, which could aid in diagnosing cancer. The discovery also provides opportunities for developing new treatments by inhibiting the enzyme.
