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].

Protocol (from reference)

Cell Assay:

[1]

  • Cell lines

    U87 astrocytoma cells, lung cancer cell lines H157 and H1437, LNCaP prostate cancer and HeLa cervical cancer cell lines

  • Concentrations

    100 ng/mL, 1 µg/mL

  • Incubation Time

    24, 72, and 96 hours
