microRNA (miRNA)
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.

You are what you eat - study suggests veg can alter your genes
Small fragments of genetic material from vegetables we eat could be altering our genes, according to a study carried out by scientists in China...
'Man flu' - do women just have stronger immune systems?
Genetic differences between men and women could mean that women are better at resisting certain infections and diseases than men, a new study suggests. The second X chromosome in women gives them an immunological advantage over men, possibly giving credence to man's perceived susceptibility to 'man-flu'....
Brain cells made from skin
US researchers have successfully converted human skin cells directly into brain nerve cells, skipping an intermediate stem cell stage. The new technique has the potential to aid research into neurodegenerative disorders of the brain, such as Parkinson's and Alzheimer's....
New method '100-fold' better at stem cell reprogramming
A novel and more efficient method for generating induced pluripotent stem cells (iPSCs) from adult cells using small RNA molecules has been discovered by researchers at the University of Pennsylvania School of Medicine in the USA...
Researchers discover 'oncogene addiction' in cancer
Researchers at Yale have identified a potential therapeutic target for cancer in the form of a micro RNA (miRNA) gene that cancer cells, but not normal cells, are dependent on for survival. Inactivating the miRNA causes cancer cell death and tumour regression....
LRRK2 gene key to Parkinson's Disease, say experts
Researchers have uncovered a genetic mutation linked to the neurodegenerative condition, Parkinson's disease, which affects one in five hundred people in the UK, mainly over the age of 60....
Small RNAs help stem cells change state
Researchers at the University of California, San Francisco, have discovered that microRNA (miRNA) play a key role in the switch in state between a stem cell and a mature, differentiated cell...
