Through their wide-ranging study, they found 50 genes that interfere with the genetic activities of the first wave.

Mayr wondered whether loss of these let-7 binding sites, and therefore loss of regulation by let-7 of Hmga2, might cause over-expression of Hmga2 that in turn would result in tumor formation. To find out, Mayr created ...... processed in distinct areas of the brain and only later integrated.
