A recent study suggests that successful genetic blueprints for mesodermal development are recycled by evolution, rather than being invented anew in different species. The researchers found highly conserved transcription factor binding sites across six fruit fly species, indicating a shared regulatory program.
Researchers have successfully imaged the three-dimensional structure of Salmonella's needle complex with unprecedented precision, shedding light on its deadly mechanism. By combining high-resolution cryo-electron microscopy and advanced imaging software, the team was able to generate a single sharp image from thousands of blurred ones.
Researchers find that the RANK protein and its ligand regulate the body's fever response, helping to fight infection. Female mice lacking RANK in the brain have increased body temperatures compared to males, with a link to sex hormones and reproductive biology.
The DREAM gene plays a key role in regulating pain perception, learning, and memory. Mice without the gene show reduced sensitivity to pain but improved memory, suggesting a link between calcium regulation and brain function.
Researchers have identified a common molecular disease pathway explaining how diverse non-infectious and infectious agents like anthrax, lung plague, SARS, and H5N1 avian influenza can cause severe lung failure with similar pathologies. Oxidative stress triggers the innate immune system, leading to severe lung damage.
Researchers found that cohesin acts as a regulator of gene expression, playing an essential role in reading genes independently of its previously known function. The molecule is also necessary for the function of insulators, which separate regions influenced by regulators.
Researchers at the Research Institute of Molecular Pathology have identified a molecular switch responsible for the behavioral changes in female fruit flies after mating. The discovery could lead to new approaches for controlling reproductive behaviors in agricultural pests and human disease carriers.
Researchers at the Research Institute of Molecular Pathology in Vienna have developed an animal model for psoriasis, revealing that epidermal alterations can initiate skin lesions and arthritis. The discovery challenges long-held beliefs about autoimmune diseases and provides a powerful tool for future studies.
