The researchers linked the excess weight and changes in metabolism to epigenetic modifications that reduce expression of the gene for adiponectin — a hormone that helps regulate several metabolic processes, including glucose regulation.

Further analysis revealed that overexpression of these lncRNAs in turn changed the expression of proteins that regulate a well - known developmental process, termed the epithelial - to - mesenchymal transition (EMT).

Nick Owens, a post doc in Mike Gilchrist's lab, who developed the computational analysis, said: «This study improves our ability to understand the way gene expression changes with time, and from this we gain insight into the logic of how gene expression is regulated.

Using novel gene - array technology to measure the extent of gene expression in thousands of genes simultaneously, this study shows that as humans diverged from their ape ancestors in the last five million years, genes for transcription factors — which control the expression of other genes — were four times as likely to have changed their own expression patterns as the genes they regulate.
