Repeats in the gene that causes Fragile X Syndrome normally regulate how and when proteins are made in neurons, a University of Michigan team has found. The process may be important for learning and memory in these nerve cells and potentially in people. “The repeats function like a switch, slowing down protein production and then… Read more

A novel mechanistic link between alterations in RNA splicing and tau-mediated neurodegeneration in Alzheimer’s disease us reported in a collaborative study in the journal Cell Reports[1]. The study, led by researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, integrates data from human brain autopsy… Read more

In recent years, MIT scientists have developed a new model for how key genes are controlled that suggests the cellular machinery that transcribes DNA into RNA forms specialized droplets called condensates. These droplets occur only at certain sites on the genome, helping to determine which genes are expressed in different types of cells. In a… Read more

Important clues to what goes wrong in the brains of people with autism have been found by A team of UCLA-led scientists. The new insights involve RNA editing — in which genetic material is normal, but modifications in RNA alter nucleotides, whose patterns carry the data required for constructing proteins. “RNA editing is probably having… Read more

A fusion gene is a new gene made by joining parts of two different genes. The current thought is that fusion genes can happen in cells with unstable genome when part of the DNA from one chromosome moves to another chromosome. When the fusion gene is transcribed into RNA, the product is a fusion RNA… Read more
