With Alzheimer’s disease medical professionals have to conduct costly brain imaging scans, and sometimes, invasive cerebral spinal fluid tests to rule out other diseases. Now, a new study from researchers … Continue Reading Human study identifies biomarker in blood for Alzheimer’s disease.
DNA methylation is essential for the proper control of gene expression and cell identity, what enables cells with the same genetic material to become, for example, a nerve cell, a … Continue Reading Single-cell imaging developed which can record DNA methylation in real time.
As humans grow older, they lose strength and muscle mass. Skeletal muscle weakness and atrophy are among the most pervasive and disruptive effects of aging. In nearly all people, even … Continue Reading Researchers identify precise cause of muscle weakness and loss due to aging.
Another step forward has just been taken in the area of synthetic biology. Research teams from Inserm, CNRS (French National Centre for Scientific Research), Montpellier Regional University Hospital and Stanford … Continue Reading Intelligent bacteria, bactodetectors, have been programmed to successfully detect disease.
When cells are normal and unstressed, the molecule keeps transcription moving so that genes are ‘expressed’ and RNA is jotted down more quickly. When cells are stressed and transcription runs … Continue Reading Researchers identify key molecule which halts transcription of cell’s genetic code.
For years, scientists have been puzzled by the presence of short stretches of genetic material floating inside a variety of cells, ranging from bacteria to mammals, including humans. These fragments … Continue Reading Researchers identify new role for tRNA fragments in tumour suppression.
RNA is both the bridge between DNA and the production of proteins known to carry out the functions of life, guiding the amount and type of protein mades. As messenger … Continue Reading The first ever study to map splicing changes during T cell development has been published.
The micro RNA miR-22 has long been known for its ability to suppress cancer. However, questions remain about how it achieves this feat. For example, which molecules are regulating miR-22, … Continue Reading Researchers being to map the epigenetic pathway of miR-22 cancer suppression.
In the battle between a cell and a virus, either side may resort to subterfuge. Molecular messages, which control the cellular machinery both sides need, are vulnerable to interception or … Continue Reading Researchers map microRNA’s role in the human hepatitis c infection.
Researchers from the UC San Diego and the University of Iowa have identified a key piece in the complex molecular puzzle underlying heart failure, a serious and sometimes life-threatening disorder affecting more … Continue Reading Researchers identify protein responsible for epigenetic change in heart failure.
Researchers at The University of Texas at Austin have identified a network of genes that appear to work together in determining alcohol dependence. The findings, which could lead to future … Continue Reading Alcohol abuse linked to newly identified neurogenetic network.
