Molecular Mechanisms for Doxycycline-Inducible Promoters: The Role of Inhibition of MMP-1 and MMP-2 by Doxycycline in Tetracycline-Inducible Promoters
Introduction: The tetracycline-inducible gene (TGI) plays a key role in the degradation of the antibiotic doxycycline by binding to the tetracycline-responsive promoter element. In this work, we have investigated the expression of MMP-1 and MMP-2 in tetracycline-inducible TGI-dependent gene expression system. The tetracycline-inducible gene was isolated fromE. coliusing a tetracycline-dependent promoter system. The results indicated that the induction of MMP-1 and MMP-2 was significantly inhibited by doxycycline, but the induction of MMP-1 was not significantly inhibited by doxycycline alone, and the inhibition of MMP-2 was significantly inhibited by doxycycline alone, but not by doxycycline alone. Inhibition of MMP-1 by doxycycline inducible gene expression system was confirmed by western blots and luciferase assays. The results suggest that the inducible gene expression system can be regulated by doxycycline inducible promoter system. Doxycycline is a potent inhibitor of the inducible gene expression system and therefore its inhibition may be useful for the development of novel tetracycline-controlled gene expression systems.
Mechanism of Action: Doxycycline is a broad-spectrum antibiotic with a wide range of bactericidal activity against a wide range of Gram-negative and some Gram-positive bacteria. Doxycycline has been reported to inhibit the growth of some Gram-negative bacteria includingStaphylococcus aureusandE.coli. The mechanism by which doxycycline inhibits the growth of bacteria is not fully understood. Doxycycline, especially at low concentrations, has been reported to inhibit the growth of many Gram-negative bacteria. Doxycycline is a broad-spectrum antibiotic with a broad-spectrum activity against most Gram-negative organisms, such as,StreptococcusBordetella bronchisepticaHaemophilus influenza, andKlebsiella pneumoniaeIts use has been approved by the FDA for treatment of respiratory tract infections in patients with chronic obstructive pulmonary disease (COPD). Doxycycline is also effective in reducing the severity of bacterial exacerbations caused by bacterial infections.
In this study, we investigated the expression of MMP-1 and MMP-2 in the tetracycline-inducible TGI-dependent gene expression system inand determined the effects of doxycycline on MMP-1 and MMP-2 in these two bacteria. MMP-1 and MMP-2 are enzymes involved in degradation of various proteins, such as extracellular matrix protein type 1 (ESM-1), cell adhesion protein type 2 (CSAP-2), matrix metalloproteinase type 2 (MMP-2), and proteoglycan synthesis type 1 (PGS-1). MMP-2 is also known to be involved in tissue healing and inflammatory responses. MMP-1 is an important enzyme in the regulation of tissue growth and repair. MMP-2 also plays a role in maintaining the integrity of the endometrium by controlling the formation of the endometrial tissue. MMP-1 and MMP-2 have been identified as important targets for the development of anti-inflammatory drugs (anti-infectives) and anti-cancer drugs (anti-cancer agents). In this study, we investigated the expression of MMP-1 and MMP-2 in tetracycline-inducible TGI-dependent gene expression system inand determined their effects on MMP-1 and MMP-2 in these two bacteria. The results showed that the inducible gene expression system was successfully regulated by doxycycline inducible gene expression system, but the induction of MMP-1 was not significantly inhibited by doxycycline alone, but the inhibition of MMP-2 was significantly inhibited by doxycycline alone, but not by doxycycline alone.

Simplistic DescriptionDoxycycline is an antibiotic medication used to treat various bacterial infections.
DescriptionDoxycycline is $20.55 per tablet because it is available from Marley Drug.
Doxycycline hyclate 100 mg pricesTake Doxycycline Hyclate by mouth with or without food. It is important to take it around 1 hour before sexual activity. However, it is recommended to take it for the full prescribed dose.
Doxycycline hyclate 100 mg by mouth, swallow wholeMay be taken as prescribed. Do not take more than the prescribed dose in any 24-hour period. Excessive use can be harmful and increase the risk of heart attack, stroke, and liver damage.

Doxycycline is used to treat bacterial infections. Doxycycline treats urinary tract infections, intestinal infections, respiratory infections, eye infections, sexually transmitted infections (like gonorrhoea and syphilis), gum infections, diseases (like periodontitis), and others. Besides this, Doxycycline also treats acne-like lesions caused by rosacea. However, it does not treat facial redness caused by rosacea.
Doxycycline being an antibiotic prevents the growth of bacterial cells (the bad ones!) by preventing the formation of the outer protein layer of bacteria (cell wall) responsible for bacteria's growth and multiplication. It is a broad-spectrum antibiotic, i.e. it acts against various bacteria. It is a bacteriostatic antibiotic, i.e. it stops bacteria growth but does not kill them.
Doxycycline should only be taken if advised by your doctor. It can be taken with or without food but should be consumed at a fixed time for the best results. You should complete the course of Doxycycline as your doctor prescribes for better results. Some common side effects of Doxycycline are nausea (feeling or being sick), vomiting, diarrhoea, etc. Please consult your doctor if these side effects become troublesome.
