[Effects of garlicin on NIH3T3 cell proliferation and collagen synthesis].

OBJECTIVE: To investigate the effects of garlicin on fibroblasts proliferation and type I collagen synthesis and explore its anti-fibrosis mechanism. METHODS: Garlicin was added into the culture fluid of NIH3T3 cell, taking Radix Salviae miltiorrhizae as the control medicine. The spiking of H3-thymidine DNA was detected, also the hydroxyproline (HOP) concentration in the culture fluid by alkali digestion method and the protein expression of type I collagen in NIH3T3 cells by immunofluorescent staining. RESULTS: The NIH3T3 cell growth and proliferation rate were obviously reduced after garlicin treatment concentration-dependently in range of 0.2 - 5 microg/mL; HOP level and protein expression of type I collagen also lowered. CONCLUSION: Garlicin could inhibit NIH3T3 cell proliferation, reduce the synthesis and protein expression of type I collagen so as to exert the anti-fibrosis effect.
