MicroRNA News and Research

RSS

In genetics, microRNAs (miRNA) are single-stranded RNA molecules of 21-23 nucleotides in length, which regulate gene expression. miRNAs are encoded by genes from whose DNA they are transcribed but miRNAs are not translated into protein (i.e. they are non-coding RNAs); instead each primary transcript (a pri-miRNA) is processed into a short stem-loop structure called a pre-miRNA and finally into a functional miRNA. Mature miRNA molecules are partially complementary to one or more messenger RNA (mRNA) molecules, and their main function is to down-regulate gene expression.

New biomarkers offer hope for early detection and prevention of Alzheimer's

The failure to diagnose Alzheimer's disease, the most common form of dementia in the elderly, at an early stage of molecular pathology is considered a major reason why treatments fail in clinical trials. Previous research to molecularly diagnose Alzheimer's disease yielded "A/T/N" central biomarkers based on the measurements of proteins, β-amyloid ("A") and tau ("T"), and "N" encompassing neurodegeneration. A/T/N can be measured in brain tissue, by in vivo brain imaging techniques, and by analysis of cerebrospinal fluid and plasma.

Gene editing silences mutant microRNA, restores hearing in adult mice

Researchers have used gene editing to restore hearing in adult mice with a type of inherited hearing loss. They showed that shutting down a damaged copy of a gene called a microRNA (miRNA) enabled the animals to regain hearing. The approach by a research team supported by the National Institutes of Health (NIH), reported in Science Translational Medicine, may eventually lead to potential treatments for inherited hearing loss in people.

MicroRNAs shed light on aggressive youthful type 2 diabetes

Type 2 diabetes in young people ages 10 to19 has more than doubled in the past 20 years, yet it remains difficult for physicians to predict who will be diagnosed and who will improve with treatment. A newly published study from the University of Oklahoma shows that measuring the circulating abundance of microRNAs – which affect insulin-producing beta cells in the pancreas – is likely as effective as measuring the level of sugar in the blood for determining how a young person with the condition will fare.
