Ageing impairs critical final egg maturation stage

Age may adversely affect women's fertility by impairing levels of RNA molecules which in turn alter the function of genes involved in key biological pathways during the final maturation stage of a human egg cell, according ...

New, highly precise 'clock' can measure biological age

Using the model organism Caenorhabditis elegans, researchers at the University of Cologne have developed an 'aging clock' that reads the biological age of an organism directly from its gene expression, the transcriptome. ...

Expert discusses RNA's role in diagnosing rare diseases

An individual's genetic makeup, or genome, can reveal important and intimate details of his or her biology. Now, scientists are showing that RNA, the lesser-known molecular cousin of DNA, is powerful in its own right and ...

A new way of finding compounds that prevent aging

Researchers at Karolinska Institutet in Sweden have developed a new method for identifying compounds that prevent aging. The method is based on a new way of determining age in cultured human cells and is reported in a study ...

New method for studying ALS more effectively

The neurodegenerative disease ALS causes motor neuron death and paralysis. However, long before the cells die, they lose contact with muscles as their axons atrophy. Researchers at Karolinska Institutet in Sweden have now ...

Redefining colorectal cancer subtypes

There is a long-standing belief that colorectal cancer (CRC), which causes some 50,000 deaths in the United States each year, can be categorized into distinct molecular subtypes. In a paper published recently in the journal Genome ...
