What is the Origin of Transrepression?

The term is a compound of the Latin prefix trans (across or beyond) and "repression," signifying the act of inhibiting or suppressing genetic transcription. The concept emerged from molecular endocrinology studies that sought to explain how nuclear receptors could modulate cellular responses in the absence of a hormone response element (HRE) on the DNA. It provides a molecular explanation for the potent anti-inflammatory action of certain steroid molecules.

What is the Mechanism of Transrepression?

The mechanism involves the activated nuclear receptor, such as the glucocorticoid receptor (GR) or the androgen receptor (AR), physically interacting with and sequestering key pro-inflammatory transcription factors like NF-κB or AP-1 in the cytoplasm or nucleus. This protein-protein interaction prevents the pro-inflammatory factor from binding to its target gene promoters, effectively repressing the transcription of inflammatory genes. This indirect silencing of the inflammatory cascade is a key therapeutic goal.

Transrepression

Meaning

Transrepression is a distinct mechanism of gene regulation where a transcription factor or a nuclear receptor suppresses the activity of another, separate transcription factor without directly binding to the DNA sequence of the target gene. This process is a critical pathway by which steroid hormones, particularly glucocorticoids and some sex hormones, exert anti-inflammatory effects by interfering with the pro-inflammatory signaling pathways. It is a non-genomic or indirect method of modulating gene expression.
