Engineering a Wolverine!! -- Interview with Junsu Kang about regeneration specific regulatory elements!

Let's imagine you are the scientist responsible for engineering a human into a mutant capable of recovering from any and all injury, like Wolverine. You would need to 'program' his genetic content to do a few things. Firstly, his body has to recognize the injury rapidly and respond to it strongly. Secondly, it should produce a potent healing genetic network, which will mostly include cell proliferative genes. Thirdly, but most importantly, this program has to be tightly controlled so that it does not have background leakage making his body defective and giving him a zillion cancers in the process. Seems like a stretch, doesn't it!

Well, seems like the puzzle might not be so enigmatic after all. Regulatory elements in our genome control gene expression in temporal and spatial manner. If one could isolate regions that are capable of tightly controlling expression between injury and recovery period, then one could use them to drive 'helpful' healing networks for enhancing regenerative abilities, without the side-effect of inducing cancer. But is it possible? Junsu and colleagues show us how to identify and characterize such regions! Please listen in to know more.
