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.
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.
