Nov. 22, 2023 Trans-vaccenic acid (TVA), a long-chain fatty acid found in meat and dairy products from grazing animals such as cows and sheep, improves the ability of CD8+ T cells to infiltrate tumors and kill ...
Nov. 17, 2023 Researchers have shown for the first time that hemoglobin, a protein found in red blood cells where it binds oxygen, is also present in the epidermis, our skin's outermost body tissue. The study ...
Nov. 17, 2023 If cells in cell cultures grow while being treated with division-suppressing agents, their growth becomes excessive and they permanently lose their ability to divide. However, if the cells are ...
Nov. 16, 2023 Researchers have discovered a 'genomic tug of war' in animal studies that could influence how well certain patients -- or certain cancers -- respond to decitabine, a drug used to treat ...
Nov. 16, 2023 A new theoretical model helps explain how epigenetic memories, encoded in chemical modifications of chromatin, are passed from generation to generation. Within each cell's nucleus, researchers ...
Nov. 16, 2023 Researchers have discovered that 'cell competition' following gene therapy results in the accumulation of stem cells with genetic mutations which make them grow faster. Some of these ...
Nov. 16, 2023 A new study finds that microglia with mutant TREM2 protein reduce brain circuit connections, promote inflammation and contribute to Alzheimer's pathology in other ...
Nov. 16, 2023 Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects neurons in the brain and spinal cord causing loss of muscle control. Scientists have now suggested a potential ...
Nov. 16, 2023 Researchers reveal that vitamin B12 significantly boosts the efficiency of cellular reprogramming, thus holding promise for regenerative medicine. Vitamin B12 supplementation shows potential in ...
Nov. 16, 2023 Investigators have developed an artificial intelligence (AI) model based on epigenetic factors that is able to predict patient outcomes successfully across multiple cancer ...
Nov. 15, 2023 Medical researchers have learned more about an enzyme found to be overly expressed in patients with hereditary breast cancer, ovarian cancer, and prostate ...
Nov. 15, 2023 Scientists mapped the gene regulatory networks responsible for progressive differentiation states of tumor-infiltrating T cells, using a technology known as single-cell CRISPR screening to knock out ...
Nov. 15, 2023 Researchers discover how ribosomes contribute to the recognition and removal of RNA crosslinking ...
Nov. 15, 2023 Scientists have 3D-printed hair follicles in human skin tissue cultured in the lab. This marks the first time researchers have used the technology to generate hair follicles, which play an important ...
Nov. 14, 2023 Exposure to ultrafine particles from traffic alters the expression of many genes in human olfactory mucosa cells, a new study shows. The study is the first to combine an analysis of emissions from ...
Nov. 14, 2023 A study of newly created databases of medulloblastoma has found that patients with tumors containing circular extrachromosomal DNA -- loops of DNA found outside of regular chromosomes -- are twice as ...
Nov. 13, 2023 An international team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer's and Parkinson's Diseases. The biosensor can also transmit the ...
Nov. 13, 2023 Fasting interventions, which involve alternating periods of fasting and refeeding, are generally thought to improve health. But these interventions don't work as well in old animals. The ...
Nov. 13, 2023 For years, researchers and clinicians have known that lupus, an autoimmune condition, occurs in women at a rate nine times higher than in men. Some of the factors that cause the disease's high ...
Nov. 9, 2023 Researchers have adapted CRISPR technologies for high-throughput screening of gene function in human immune cells and discovered that a single master regulator of the genome can be used to reprogram ...
