Hormonal induction of transfected genes depends on DNA topology.

abstract：:The erb A oncogene is a dominant negative allele of a thyroid hormone receptor gene and acts in the cancer cell by encoding a transcriptional repressor. We demonstrate here that the DNA sequence recognition properties of the oncogenic form of the erb A protein are significantly altered from those of the normal thyroid...
