Biological Activity

Description	Doxycycline (Vibramycin, Doxytetracycline, Doxiciclina, Doxycyclinum) is an antibiotic that is used in the treatment of a number of types of infections caused by bacteria and protozoa. Doxycycline is also a nonspecific matrix metalloproteinase (MMP) inhibitor.
In vitro	100 ng/mL-5 µg/mL Dox can significantly alter the metabolic profile of the cell, as well as reduce the proliferative rate, though the effect size depends upon the particular cell line used^[1]. Doxycycline arrests cells in G1-S phase of the cell cycle in PANC-1 cells and induces the expression of p53 and its downstream target p21. It down-regulates antiapoptotic genes and induces proapoptotic genes. Doxycycline also induces apoptosis through a Fas/Fas-ligand dependent pathway in Jurkat T lymphocytes^[2].
In vivo	Doxycycline successfully reduces tumor growth in vivo (inhibited pancreatic cancer cell growth)^[2].
