The World Health Organization’s 2014 data indicates that about 9% of the global adult population (age > 18) suffered from this disease and more than 1.5 million people died from complications caused by diabetes. Governments and private companies invest huge amounts of money into research to fight diabetes each year.

Seasonal Variations in Gene Expression

A lot changes in the fall – temperatures, leaf colors, coffee flavors, sunrise time, TV shows, it's a long list. Add to this list your transcriptome. A transcriptome is the set of all RNA molecules in a cell or population of cells. The name comes from transcription, which is the first part of gene expression where information in a strand of DNA is copied into messenger RNA. The DNA information in a eukaryotic organism, e.g. the genome, is more or less constant apart from the occasional mutation. In contrast the transcriptome is in constant flux.
