Researchers uncover ‘circular logic’ of RNAs in Parkinson’s disease
Scherzer and colleagues laser-captured neurons from 190 frozen postmortem human brain samples, including some non-neuronal cells for comparison. Then, they used ultra-deep, total RNA sequencing to study the exact sequences…

Alzheimer’s disease is partly genetic − studying the genes that delay decline in some may lead to treatments for all
Diseases that run in families usually have genetic causes. Some are genetic mutations that directly cause the disease if inherited. Others are risk genes that affect the body in a…
Can at-home DNA tests predict how you’ll respond to your medications? Pharmacists explain the risks and benefits of pharmacogenetic testing
Have you ever wondered why certain medications don’t seem to work as well for you as they do for others? This variability in drug response is what pharmacogenomic testing hopes…
Study links epigenetic changes to historic trauma in Alaska Native communities

Gene-tweaked stem cells offer hope against sickle cell disease
A type of gene therapy that precisely “edits” a key bit of DNA might offer a new way to treat sickle cell disease—a painful inherited condition that largely strikes Black…
Study findings provide new insight into how breast cancer evolves
The der(1;16) translocation-positive breast cancer originated from a single cell around puberty. This cell repeatedly underwent cell division and expanded until it developed into breast cancer several decades later. Then,…
Gene Mutation Sheds Light on Schizophrenia Mysteries
Summary: Scientists developed a mouse model that carries a genetic mutation linked to an increased risk of schizophrenia. By studying the Grin2a gene, they found significant changes in gene expression,…
Schizophrenia gene mutation causes many changes in the mouse brain, new study shows
Researchers studied the effects of a schizophrenia gene mutation in different regions of the mouse brain. Credit: Susanna Hamilton, Broad Communications Researchers have identified common and rare gene mutations that…
