Messenger RNA (mRNA) stability plays a crucial role in determining disease severity in nervous system mutations, according to researchers at Baylor College of Medicine. Aberrant mRNA forms are usually eliminated through nonsense-mediated decay, but some escape and lead to defective protein production.
Researchers at UNC School of Medicine have identified a novel enzyme that halts histone synthesis when no longer needed, preventing lethal cell damage. The discovery sheds light on the complex regulatory mechanisms governing histone mRNA expression.
Researchers have discovered that microRNAs play a crucial role in controlling plant growth and development by regulating cell division and leaf shape. The study found that a specific microRNA called "Jaw" targets messenger RNAs involved in preventing excessive cell division, leading to abnormal leaf shapes.
Researchers at TSRI introduce a revolutionary method to add unnatural amino acids to the genetic code of Saccharomyces cerevisiae yeast. This allows for unprecedented control over protein structure and function, enabling new insights into biological processes and potential therapeutic applications.
Researchers have discovered that a small protein, SmpB, helps modify the structure of tmRNA to facilitate its role in repairing damaged mRNA. This process prevents the production of toxic proteins and ensures cellular survival. The study also reveals how a plant virus exploits this mechanism for its own replication.
A new tool called APRA allows for detailed analysis of mRNA molecules in intact cells, revealing key interactions with the Fragile X Mental Retardation Protein (FMRP). The study provides a potential approach to develop new treatments for Fragile X syndrome, a genetic disorder that affects mental development.
Researchers have devised a method to correct RNA splicing defects implicated in breast cancer and spinal muscular atrophy. The technique uses designer molecules that can be programmed to bind to specific pieces of RNA, correcting the splicing error and producing normal messenger RNA.
Researchers developed a non-invasive method to generate a genetic fingerprint of fertile men's sperm cells, identified around 3000 individual mRNAs, and suggest it could help diagnose idiopathic infertility and reveal paternal influences on fetal development.
Researchers developed a new technique to analyze RNA splicing in yeast, revealing the complex process of gene expression. By studying yeast genes with DNA microarrays, they gained insights into alternative splicing and its role in human diseases.
Researchers at Stanford Medicine have identified hundreds of new genes involved in multiple sclerosis (MS) progression. The study found genes expressed differently in acute and chronic attacks, including those associated with pregnancy and allergic responses, which could lead to new treatment strategies.
Scientists found that viruses causing diverse ailments like AIDS, common cold, and hepatitis share functional traits, linking large groups of viruses. These traits involve replication mechanisms and messenger RNA stages, suggesting a common ancestor among the viruses. The discovery bolsters prospects for broad-spectrum antiviral agents.
Researchers at Emory University Health Sciences Center have identified specific genes in the brain associated with Fragile X Syndrome, a genetic disorder causing mental retardation and related problems. The study used DNA microarray technology to discover 251 dysregulated mRNAs in cells from patients with fragile X syndrome.
Researchers at University of Pennsylvania School of Medicine have discovered a pattern to protein manufacture in the hippocampus, which may help explain how memories are stored. The study found that protein synthesis in dendrites is exponentially faster than in the cell body, with specific patterns emerging.
Researchers used DNA-coated microchips to discover that flavopiridol works by broadly inhibiting messenger RNA molecules, which are responsible for carrying genetic information to cellular protein factories. This inhibition ultimately leads to a halt in the production of certain proteins, allowing normal cellular processes to continue.
Researchers at UC Davis have found that genes in one part of a plant can override the genetic program in a distant part, changing how it grows. They also developed a new method to permanently bind radioactivity to antibodies to deliver cancer treatment.
Researchers obtained the most detailed images of the ribosome's factory, where amino acids are linked into proteins. The high-resolution structure reveals that the ribosome is a ribozyme, an RNA enzyme, and provides insights into its evolution and function.
Researchers used three-dimensional cryo-electron microscopy to visualize the ratcheting rotation of ribosomal subunits relative to each other. This motion facilitates translocation of mRNA and tRNA during protein synthesis.
