Researchers at Nara Institute of Science and Technology identified the WOX13 gene as a key negative regulator of shoot regeneration in plants. The study found that WOX13 inhibits a subset of shoot meristem regulators while directly activating cell wall modifier genes involved in cell expansion and differentiation.
Researchers have discovered that gene editing technologies may introduce unintended mutations and damage to DNA in early human embryos. The study found that most cells repair breaks in the DNA using non-homologous end joining, which can lead to additional genetic abnormalities.
Researchers analyzed 557 subjects to link genetic variations, brain structure, and behavior to intelligence test performance. They found specific brain areas where gene variations influence brain characteristics, which in turn affect intelligence.
Researchers at NIH's National Human Genome Research Institute identified a gene, KTD1, that provides resistance to the K28 toxin in yeast. This discovery sheds light on the molecular mechanisms underlying toxin resistance and has implications for understanding human toxin resistance.
A Geisinger Health System study found that individuals with an additional X or Y chromosome have a four to five times higher risk of developing venous thromboembolism, a life-threatening condition. The analysis included data from over 642,000 patients and suggests that identifying those at high risk could minimize unnecessary illness a...
Researchers have solved an 80-year-old medical mystery that causes kidney damage in children and can be fatal in babies. They discovered a gene mutation is the primary cause, but found that around 10% of patients without the mutation still experience symptoms.
Researchers at Okayama University discovered genes and proteins responsible for the rapid contraction of axopodia in Heliozoa, a group of eukaryotes. The study identified key players in microtubule disruption, including katanin p60, kinesin, and calcium signaling proteins.
Researchers found four genetic populations of the finless porpoise in Chinese waters and three in the Gulf of Thailand, with unique matriline lineages. The study suggests ongoing gene flow among populations, requiring careful evaluation of inter-population connectivity for conservation action.
A gene called CRTC1 suppresses obesity when functioning in specific neurons, but its deletion leads to overeating and weight gain. Researchers created mice with a modified version of the gene to study its effects on obesity and diabetes.
Researchers from the Netherlands Cancer Institute have discovered a new 'mystery gene' responsible for maturing the actin protein, a main component of the cell skeleton. The findings shed light on the complex process by which proteins are completed and functional in cells, with potential implications for understanding muscle diseases.
Researchers discovered a rare genetic mutation that may lead to better diabetes treatments for patients, regardless of whether they inherited the mutation. The study found that carriers of the mutation had lower levels of adiponectin and higher levels of ceramides in their blood.
A new study found that ageing desexualizes the Drosophila brain transcriptome, causing both males and females to exhibit reduced gene expression differences. This effect is larger in males than females, indicating a weaker investment in sexual behaviors as they age.
Researchers have developed Fanflow4Insects, a functional annotation workflow that annotates gene functions in insects. The team has annotated the Japanese stick insect and silkworm, providing valuable information for entomological research and genome editing.
Researchers found that tendons, not muscles, are the key site where increased mechanosensitivity translates to better running and jumping capabilities. High expression of the calcium-ion channel mechanoreceptor coincided with wider tendons composed of larger collagen fibrils.
Scientists have identified the DOMINANT AWN INHIBITOR (DAI) gene in sorghum, which regulates the absence and shortening of awns. The gene encodes a protein that negatively regulates awn formation as a transcription factor, with implications for breeding modern awnless cultivars.
A study led by Brigham and Women's Hospital investigators has revealed that alpha-synuclein plays a dual role in Parkinson's disease, interacting with both vesicles and P-body structures. This new understanding may lead to targeted treatments for the disease, with ongoing genetic studies aiming to identify optimal therapeutic targets.
Researchers identify genetic determinants of immune phenotypes in type 1 diabetes, highlighting 11 genes as potential candidates for new treatments. Genetic variants affecting T-cell composition and cytokine production were found to be significantly involved in the disease.
Researchers at UC San Francisco have identified five genes that enable efficient sleep, contrasting with current thinking that lack of sleep accelerates neurodegeneration. These genes may confer protections against neurological disease and improve sleep quality, paving the way for new treatments.
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 discovered a population of Colorado blue columbines that have lost their petals and nectar spurs due to a single gene mutation. The finding supports the punctuated equilibrium hypothesis, suggesting that adaptation can occur in large jumps rather than gradual changes over extended timespans.
Researchers developed a new method to complete genetic data gaps using haplotype blocks, improving breeding efficiency in plants. The approach has shown comparable quality to collecting more information from DNA strands, reducing costs in animal and plant breeding.
Researchers from Hiroshima University analyzed 839 collections of genetic material to identify common features of oxidative stress. They found two genes, CRIP1 and CRIP3, downregulated during oxidative stress, suggesting a relationship with zinc homeostasis. The study also identified shared biological processes between the two types of...
Researchers found that patients with a rare genetic condition may develop chronic inflammatory bone diseases due to an impaired response to interferon gamma. The study suggests that this impairment leads to excessive osteoclast proliferation and increased bone resorption, causing multifocal osteomyelitis.
Researchers found that high levels of complement protein Ba are a reliable indicator of transplant-associated thrombotic microangiopathy development, contrary to previous reports. The study's findings provide hope for developing prophylactic treatments to prevent the disease.
