Gene therapy could prevent breast cancer from spreading
A new gene therapy technique using microRNAs has successfully prevented the spread of breast cancer in mice...
MicroRNAs are small, non-coding RNA molecules that regulate gene expression by suppressing the RNA pathway that translates genes into protein. They act like 'master switches', having the ability to control the activity of multiple genes.

The general public have appropriated the term DNA to mean much more than just the molecule itself. This may not be a problem most of the time but, in the case of donor eggs and sperm in particular, it's important that people are clear on what genetics and epigenetics really tell us...
A recent study suggests that embryonic gene activity may be altered by factors present in the womb even before implantation. This finding triggered a somewhat misleading newspaper article entitled 'Infertile mums "pass on DNA"', which claimed the research means recipients of donor eggs are passing on their own DNA to their child. This isn't the case...
Researchers have identified a biological process that may cause the failure of embryos to attach to the uterus wall during IVF, raising the possibility of future treatments...
Stress in early life can alter the production of small sections of the genetic material RNA in the sperm of mice, affecting behaviour not only in the mice themselves but also in their offspring, research suggests...
