His idea was initially considered controversial but in the early 1970s Unger managed to show that the rate of metabolism of animals and humans is dependent on the relative concentration of insulin to glucose (Marcus
Remarkably, ER-, but not ER-specific ligands, lead to increased phosphorylation of ERK 1/2, which initiates cell cycle entry (demonstrated by the up-regulation of mitotic markers such as CDK1/cdc2 and PCNA), DNA replication, and duplication of the centrosome -the major microtubule-organizing center in the cell- in dividing cells (Wang et al., 2008)
