Keeping the boron out of the ER: A genetic switch was engineered that activates gene expression in the presence of H2O2 (see scheme). The use of a boronate group on an estrone molecule allows for activation of gene expression through binding of the estrogen receptor only when the boron group is oxidized by H2O2. This sensor is highly sensitive and specific for H2O2.
