A previously mysterious small RNA molecule in mice is found to play a crucial role in gene expression, and may be the first identified member of a new class of regulatory RNAs.
Have you ever wondered why we carry two copies of each chromosome in all of our cells? During reproduction, we receive one from each of our parents. This means that we also receive two copies, or alleles, of each gene—one ...
RNA (ribonucleic acid), which is made up of ribonucleotides, is a molecule found in all living organisms. RNA is thought to have probably preceded DNA in primordial life billions of years ago. RNA was eventually replaced ...
To carry out all of life's functions, proteins must be produced from instructions carried by genes within DNA and delivered to the cell's protein-making machinery by messenger RNA.
A new molecular technology capable of binding to mRNA and regulating gene expression may offer a new avenue for treating diseases caused by haploinsufficiency, or the absence of one functional gene copy, according to a study ...
Scientists have shown how a molecule with broad-spectrum antibiotic activity works by disabling a process vital to bacterial growth without affecting the normal functioning of human cells. The journal mBio published the work, ...
The cells in our body continuously keep each other informed. They do this by exchanging, among other things, virus-like vesicles. Pascale Zimmermann's group, from the Department of Human Genetics, has been studying these ...
A broad-spectrum antiviral drug candidate, 2-thiouridine, that targets positive-strand RNA viruses has been identified and characterized.
Identifying different types of body fluids can help forensic experts reconstruct a crime scene, but it's difficult to do so. In a study published in Electrophoresis, researchers developed a method using two different types ...
Messenger RNA (mRNA) vaccines are revolutionizing the therapy of cancer. They can be flexibly developed in a short period of time, allowing transient expression of multiple antigens for safe and efficient immunization. A ...
