Abstract

Doxycycline is a member of the tetracycline group and is a bacteriostatic antibiotic. Therefore, it stops/slows down the reproduction and spread of pathogenic microorganisms and gives the immune system the necessary time to destroy them. In this study, cytotoxic, anti-proliferative, and apoptotic effects of doxycycline on the rat glioma cell line derived from Rattus norvegicus were observed. To show the cytotoxicity of doxycycline, MTT test was performed to obtain the IC50 value and the dosages of treatment were determined accordingly. With the colony formation test, it was observed that the determined doxycycline dosages reduced the colony formation ability of the single cells. Similarly, wound healing test also showed that doxycycline treatment reduced the ability of cells to migrate. A dose-dependent decrease in the cell number was detected by DAPI staining after doxycycline treatment and the expression levels of cancer related genes were shown by the RT-qPCR method. In conclusion, doxycycline was found to have anti-proliferative and cytotoxic effects in rat glioma cell line, and more comprehensive studies are needed before doxycycline can be used as a complementary agent in cancer treatment.
