Example of a T-REx system controlling the expression of shRNA. Tetracycline-controlled transcriptional activation is a method of inducible gene expression where transcription is reversibly turned on or off in the presence of the antibiotic tetracycline or one of its derivatives (e.g. doxycycline).
The overall structure of TetR can be broken down into two DNA-binding domains (one per monomer) and a regulatory core, which is responsible for tetracycline recognition and dimerization. TetR dimerizes by making hydrophobic contacts within the regulatory core. There is a binding cavity for tetracycline in the outer helices of the regulatory domain.
Members of the tetracycline class of antibiotics are often used as research reagents in in vitro and in vivo biomedical research experiments involving bacteria as well in experiments in eukaryotic cells and organisms with inducible protein expression systems using tetracycline-controlled transcriptional activation.

Ras gene can be combined with rtTA (reverse tetracycline transactivator) to generate bi-transgenic inducible mouse model through tetracycline-controlled transcriptional activation e.g. mice carrying TetO-KrasG12D (TOR) and MMTV-rtTA (MTB), comes with the transgene expressing the reverse tetracycline transactivator (rtTA) in mammary epithelial ...
Tetracycline hydrochloride is available as yellow crystalline powder. Since tetracycline is absorbed into bone, it is used as a marker of bone growth for biopsies in humans. Tetracycline labeling is used to determine the amount of bone growth within a certain period of time, usually a period around 21 days.
Inducible systems - An inducible system is off unless there is the presence of some molecule (called an inducer) that allows for gene expression. The molecule is said to "induce expression". The manner by which this happens is dependent on the control mechanisms as well as differences between prokaryotic and eukaryotic cells.
Housekeeping genes account for majority of the active genes in the genome, and their expression is obviously vital to survival. The housekeeping gene expression levels are fine-tuned to meet the metabolic requirements in various tissues.
