Just got finished watching a fascinating NOVA program entitled, “Ghost in Your Genes” which was about epigenetics. Epigenetics is the study of genetic modifiers called “epigenomes” that are instrumental in turning on and off the varied features of any given genome. The Human Genome Project of the early 90’s was monumental as it mainly purposed to identify all of the genomes or “genes” in the DNA make-up of humans. In 2000 they reported that they had found 22,000-23,000 genomes, which was surprisingly less than they had anticipated. That’s roughly the same that can be found in worms, rats, and frogs. Since it has been thought that humans are more genetically complex, it left many questions about what causes some genes to appear and others not to appear. The salient example of this question is how identical twins which have the exact same DNA structure can develop differently. The answer that has been found in the past few years is the discovery of “epigenomes” which can attach themselves to certain genes or gene sequences and turn them on or off depending on the circumstances. Moreover, they are finding that epigenomes can be influenced early in development, showing that although we inherit genes and epigenomes naturally through our parents, it is how we are nurtured that can determine which traits develop in us. That is certainly a simplification of very complex research, but nonetheless very compelling. They have now launched the Human Epigenome Project to try to identify what could be millions of epigenomes influencing genetic development. This is very exciting, and they have already benefited from this kind of research in cancer treatment.
