Researchers at Johns Hopkins University have developed a new molecular switch that can transform bacteria into working sensors. The device, created using a novel fusion technique, shows promise for detecting cancer cells, releasing drugs, and monitoring chemical or biological agents.
Scientists have developed a new fluorescent protein probe to study cyclic AMP activity in living cells. The probe allows for real-time monitoring of cyclic AMP's impact on cellular responses, revealing its importance in various biological processes.
The melanocortin-4 receptor's (MC4R) basal activity is essential for maintaining energy balance. The N-terminal domain of the MC4R protein is responsible for this activity. Deletion of this domain impairs the receptor's ability to regulate energy homeostasis.
USC researchers detail process of beak formation in journal Science, identifying BMP4 as a major mediator of beak shape. The study sheds light on how different bird species develop uniquely shaped beaks reflecting their ecological niches.
Researchers have identified a gene essential for the synthesis of a novel plant hormone that regulates shoot branching. The hormone is believed to be a carotenoid derivative, with a protein that can cleave carotenoids such as carrots' orange pigment.
Researchers have identified a protein called RIP140 that blocks the expression of UCP1, leading to increased energy expenditure and reduced fat accumulation. This discovery could lead to novel obesity treatments by increasing the activity of UCP1.
Researchers at Dana-Farber Cancer Institute have identified a protein, TRIM5-alpha, that blocks HIV replication in monkey cells. This discovery opens new avenues for intervening in early HIV infection and provides critical insights into viral uncoating, a little understood step in the viral lifecycle.
The study reveals N-WASP activity in unexpected cellular compartments, including ruffles on the cell membrane and the nucleus. The team's new technique allows for visualization of protein activation and its integration with cellular signaling processes.
Researchers have discovered a common pharmacophore that can be used to develop more potent and selective lethal factor inhibitors. This breakthrough holds promise for developing new anthrax therapies, particularly in cases where antibiotics are not effective.
Researchers discover protein CPEB uses prion properties to strengthen synaptic connections, enabling long-term memory storage. The finding challenges traditional views of prions as toxic and suggests they may play a key role in fundamental processes.
Researchers at Johns Hopkins University have developed a technique called domain insertion to join two proteins, creating a microscopic protein partnership where one controls the activity of the other. This could lead to specialized molecules that deliver lethal drugs only to cancerous cells and biological warfare sensors.
Scientists have improved understanding of TGF-beta's regulation in Marfan syndrome by studying mice with genetic mutations. They found that blocking TGF-beta activity during development may prevent features of the disorder, including emphysema and aortic rupture.
Researchers at Purdue University have discovered a single protein that sets the length of periods of activity and inactivity within cells, known as the biological clock. The discovery has significant implications for medicine, including minimizing jet lag and determining optimal cancer treatment timing.
New research has solved a long-standing mystery about DNA unzipping, revealing that it requires at least two proteins working together. The study found that if one protein falls away, the process stops and DNA reverts to its zipped state unless another protein joins in.
Researchers at Cold Spring Harbor Laboratory found that visual stimulation causes neurons to sprout new branches, a process that requires increased activity of certain proteins and decreased activity of others. The study provides insights into how visual stimulation guides the development of normal brain architecture.
Researchers found that a single fly gene encodes two proteins with opposing actions: one inhibits the other's activity. This discovery provides insight into complex biological phenomena and may lead to novel treatments for human cancers, particularly those with overactive STAT proteins. The study highlights the importance of considerin...
A recent study reveals that mutations in the FBN1 gene can cause Marfan syndrome by disrupting an exonic splicing enhancer, leading to exon skipping and compromised fibrillin protein activity. This understanding may help explain other human diseases associated with exon skipping.
Scientists create protein SPICE to study variola's role in immune system, with potential to reduce side effects from vaccination. By understanding the virus's pathogenesis, researchers hope to develop new therapies and prevent bioterrorism.
Researchers found that forager bees have lower activity levels of a protein called acetylcholinesterase (AChE) in their brains, which may lead to enhanced cognitive performance. A study led by Gene E. Robinson at the University of Illinois showed that reducing AChE activity improved learning abilities in foragers.
Researchers found that p53 and GR interact to balance cell survival and death in response to environmental stress. JIP1 protein is crucial for activating the JNK signaling pathway, which helps neurons respond to severe hypoxic stress.
Researchers have discovered a crucial genetic element that regulates alpha-synuclein protein activity, which is involved in both inherited and non-inherited forms of Parkinson's disease. By identifying this element, scientists hope to gain insights into the underlying mechanisms of the devastating disease.
A recent study published in the American Journal of Clinical Nutrition found that physical activity has a greater impact on preschoolers' weight than diet. The research, which followed 77 preschool children for four days, showed no significant correlation between energy intake and body fat percentage.
Scientists at Oregon Health & Science University have discovered a naturally occurring protein, herstatin, that inhibits the functions of the HER-2 oncogene, a major factor in breast and other cancers. Herstatin blocks the HER-2 signaling activity that causes tumor cells to grow, ultimately killing those cells.
Researchers at Duke University have discovered that spontaneous neural activity plays a key role in organizing the visual cortex, contradicting current theories on ocular dominance. The study used young ferrets with closed eyes to record brain activity patterns and found that input from one eye drives the entire system.
A recent study by the American Heart Association found that physical activity significantly reduces the risk of stroke in individuals aged 45-64. Those who were more active at work had a 49% lower risk, while those with high levels of sports activity had a 23% reduced risk.
Scientists identify a common gene family responsible for generating rhythmic electrical impulses in both the brain and heart. This discovery could lead to the development of screening tests and therapeutic applications for cardiac and neurological disorders.
