What is the Origin of Hormone Response Elements?

The discovery of HREs was a major breakthrough in molecular endocrinology, emerging from rigorous research into how steroid hormones, unlike peptide hormones, are able to directly influence the nucleus and gene expression. This research provided the physical, molecular link between an external chemical signal and the core genetic machinery of the cell, establishing a key concept in transcriptional regulation.

What is the Mechanism of Hormone Response Elements?

The mechanism begins when a lipophilic steroid hormone, such as testosterone or cortisol, binds to its corresponding intracellular receptor protein. This binding event activates the receptor, causing it to translocate to the nucleus and dimerize with another activated complex. The hormone-receptor dimer then recognizes and binds with high affinity to the specific HRE sequence on the DNA. This precise binding event either promotes or represses the transcription of the adjacent gene, leading to a controlled increase or decrease in the synthesis of the corresponding protein, thereby executing the hormone's physiological command.

Hormone Response Elements

Meaning

Hormone Response Elements (HREs) are specific short DNA sequences located in the promoter regions of target genes that are directly regulated by steroid and thyroid hormones. These sequences serve as essential binding sites for activated hormone-receptor complexes, which directly regulate the rate of gene transcription. They function as the molecular switches that translate a hormonal signal into a precise, lasting change in protein synthesis and overall cellular function.
