Murphy found that the normal pattern of gene activation seen in aging wild - type C. elegans was reversed in the body cells and oocytes of IGF - 1 mutants.

Dr Matthew Hobbs, Head of Research for Diabetes UK, said: «We know that preserving or restoring even relatively small levels of insulin secretion in Type 1 diabetes can prevent hypoglycaemia (low glucose levels) and reduce complications and therefore much research has focused on ways to make new cells that can be transplanted into the body.

Building upon their earlier research on the biology of fat metabolism, Joslin scientists discovered that microRNAs - small RNA molecules that play important roles in regulation in many types of tissue — play a major role in the distribution and determination of fat cells and whole body metabolism.

Since those discoveries, researchers have found that nearly every cell in the body contains a circadian clock, and almost every gene follows circadian rhythms in at least one type of cell.
